Hello and welcome to Automation Talk where you have the opportunity to see and hear live what's happening here at Automation Direct. If this your first time logging into Automation Talk we welcome you and thank you for coming in today. My name is Shane Crider and I'm the host, as I usually am, here on Automation Talk. Today, joining me to help put on this presentation is Tom Elavsky and he's my side kick, partner in crime and helps me a come up with all these seminars and try to put these on, and give our customers the best information we possibly can through our Automation Talk show. This is "Ethernet Communications" - you signed up for it - so you should know what it is, but if not... If we could get started on this, the opening slide here and everything - Shane if I can jump in... Basically we are going to cover all our products that have some form of ethernet capabilities. That might be the standard ethernet where you're communicating protocol or programming from a PC to PLC or PAC we got to start using the word PAC. That's our newest product, the Productivity 3000 we'll talk about that a little bit today but also we're going to cover the ethernet capability when it comes to our C-more HMI panels and also our Stride ethernet unmanaged type switches we'll talk about them a little bit and there's also capability with ERMs an EBCs and I am going to pass that off to shane 'cause he's kind of the expert that area. I don't understand this language of ERMs and EBCs I think we'll... you'll explain them. We'll also talk a bit about GS and DuraPulse type drives and the addition of a GS... what is it... a GS E drive... to it So more lingo not RS485 but ethernet Ethernet, ethernet is the way to go you don't want to go serial communications unless you have to and we're gonna discuss a little bit about the advantages of ethernet over serial. Yah we'll actually show some examples the slide there says ethernet communications. He had done ethernet seminars way back... I think we stopped in like 2007 Bruce Perry over in tech support would do it with me and it was ethernet PLC communications and that's all we covered was just the PLCs, but we've launched so many new products with it, more than just PLCs Tom and I are going to try to cover everything today as you see on the slide I think I'll bring up we're going to touch base on it a couple times, but you know the original ethernet was classified as 10 base T meaning 10,000 megabits per second, the newer rate is 100,000 some of the equipment we're going to be covering is rated at both 10 and 100 and we do still have some products and we'll try to point those out that only communicate at the 10 like the GS drive, the GS-E drive interface card Well sometimes its not necessary for a faster speeds on some of the products, I mean the ethernet makes it nice and easy for communications and talking, but as far as speeds go, some devices aren't, you know, as critical and like Tom says used to, we had and I even noticed when I was laying the products out and ran across some of our older for instance an ECOM which is just an ethernet communications module. Sorry, I'm sitting on the wrong side of the studios. This is the first-time I ever sat on this side, so I'm gonna look at the wrong camera way too many times bear with me yeah, our old ones were just like this 205 ethernet communications it's a H2-ECOM and the old ones just say H2-ECOM when I picked it up I was laying them out and I thought Oh! That's an old one! The new ones say H2-ECOM100 which will do 10 base or 100 base. It automatically senses the differences coming through the ethernet cablel. The other thing I would like to point out real quick we're gonna talk about is not everything we're going to talk about today with an ethernet cable is strictly ethernet type protocol and communications some of the things we'll talk about use ethernet cable to actually do remote IO Ok so next slide. Introduction Industrial ethernet today according to Automation World, actually this year, still the fastest growing wire based or wireline type infrastructure that's used in industry I think the reason why is because it's so common that most and correct me if I am wrong, its sort of an open protocol it's not a proprietary communication so pretty much anybody can create, you know, write the drivers that and put it in their product so it's a nice protocol that'll go across different manufacturers products so not only will it work with ours it will work for brand x, brand y, and brand z so that's why. The other thing with this seminar we're gonna have today We're going to try to cover all the Automation Direct products including PLCs, the switches, and the drives that make use of ethernet, ethernet protocol, and ethernet type cabling and wiring and we're also still going to do the demo with the serial and the ethernet that Shane was showing me earlier that was kind of impressive to me because I'd never seen it before Some of those hidden links in DirectSOFT that we never knew existed until we had to Alright The agenda, like I said we're just gonna go over everything, technical overview of some of the PLC stuff the industrial stuff, and then you know common communications amongst the products We'll do a quick demonstration on the Productivity3000 ethernet, on just how easy it is to connect up with it and I'll open up DirectSOFT to show you how to create ethernet links with it actually serial link as well and then difference in the speeds of serial vs ethernet and then we've got some actual customer examples in here, we haven't done any of these in a while its tough to get customers to cough up some of their examples so if you actually have some examples that you want to send to us on any of this stuff feel free to send it to us and our marketing department can always use it and we'll give you back for free and then we'll have some information we could pass on to help you out with this stuff alright, little bit in the uses of ethernet and I think we've already talked about this, but you know, here's kind of a quick don't try to wire to this graphic we have up here it's just a pictorial representation of all the devices... it's a nice one... actually one of our graphic artist just completed this for us yesterday but we're gonna cover programming by way of ethernet were gonna cover ethernet remote IO and networking between PLCs, peer to peer also the C-more which gets into operator interfaces we'll talk a little about the drives and also, we'll mention that ethernet is good for data type systems to collect data jump too quick ok there we go okay remote IO really quick I don't know... correct me if I'm wrong, do we go into some slides that actually dive down deep into the the remote io or we going... I think we are going to wing that on... a little bit on the demo or something Okay, right. Well some of the stuff we mention, we say ERMs, EBCs, a lot of customers might not know what it is but for remote IO, used to, excuse me, if you're not familiar with Koyo or DirectLogic or Automation Direct, which is all the same stuff our remote IO, used to, if you had let's say a 205 Rack, which, one of these nice racks here and I'll make sure I don't get myself shocked or try not to but the 205 Rack its one of the most popular, we have been selling these for years but when you ran out of space in the 205 the only way you could get more rack was to use serial remote IO, now we have a solution for that now on the newer stuff you can actually do an expansion rack but serial remote would allow you to run long distances, but like I said it was a two wire with a ground twisted shielded cable what was the hardest part of that was actually the configuration in trying to setup all the IO that point you had account for everything that had to get it in to the ladder logic Yeah, you had to code for everything then you had to have spec cable and resistors and if you didn't have everything just perfect and you didn't hold your mouth right it wouldn't work and there was worksheets you actually had to plug-in how many IO you actually had, where each module... so forth and so it got... it worked and it worked great once you had it set up, but the time that you had spent on it to get to work, and then... I don't know its probably been 7 years maybe they came out with ethernet remote IO and we'll show you the demo here on how much easier it is and whats funny was when they first came out with the ethernet remote IO it came out before the DirectSOFT5 which has iBoxes or intelligent boxes so when they first came out with the ethernet remote i you know it's easier ot it was easier at the time to set up analog in a slave rack than it was to set up analog in your main rack because with ethernet remote IO you can say, okay here's my analogs, it saw it you can say, okay here's the memory addresses I want it to log to and it was set up and actually I remember taking a couple calls from a couple customers the time on I was on tech support with you, that customer had a application where it involved a lot of analog type cards and the easy solution was actually put all the analog cards in the remote bracket and have more or less automatic setup on the cards so yeah that's a little bit on the remote IO stuff now PLC to PLC networking you still do serial you know if you still do RS485 or 422 but there's, you know, drawbacks on it but there's also some drawbacks on ethernet what's nice for the ethernet is it's not as susceptible to noise and some of the others are, the serials are with ethernet it's pretty much plug and go and ethernet cable I'm sure I'm gonna unplug this and something is gonna flip out here but I'm gonna do it anyway Ethernet cable, if you've been into any of the big box stores if you've been into discount stores if you've been into a drug store you've probabaly seen an ethernet cable. Hardway stores should sell it. Gas stations sell them. You get any new products, typically they throw one or two in there if you have a computer it you know what it is internet it's an RJ45 connector and you can make 'em yourself, actually some of the home improvement stores sell the tools, you can get them at RadioShack stuff like that and make them yourself its like 8 conductors. Right, we'll show the difference in the wiring how much easier wire one of these, serial as well but doing PLC to PLC communications it's pretty much plug up to the PLC and you can go to a hub you don't have to, but you can go to hubs broadcast out, Toms got a lot of nice hubs there. I was gonna kinda highlight our newer Stride unmanaged switches and real quick if you want to know the difference between a hub and a switch, basically any kind of packet of data that comes into a hub is actually rebroadcast out to all the ports on the hub where as on the switch it actually has some intelligence and basically anything coming in and once it where its being routed to, it remembers that so the next time time it gets it out there onto whatever that device is but besides that it also does not broadcast to devices that don't need that information which gets the throughput up there for you. So it doesn't clog the network. And real quick since I have the Stride here in hand... We also have Stride in two different versions. There's the original plastic case, I don't have the spects in front of me but it was like 50 degrees C on the max and then we came out with a metal housing that gets you up to, I think its 55 degrees C But we have them in five port, eight port, nine port; also fiberoptic we talked ethernet and we talked RJ45 but fiberoptic is used quite extensively for the same protocol that's transmitted You can do longer distances with the fiberoptic but it's gonna cost you a lot for your cabling and installation okay HMI to PLC communications You know, there again, ethernet. Whats nice about that, as just a quick example... specially, lets just use this for an example we've got a 260 CPU in this 205 well if we were using serial communications to a touch panel like one behind my head back there it looks like a window, that thing back there, its so large then you're take up one of your ports, right? So that leaves you one port for that and for the HMI and port for communicating to your computer for programming well that's it, you just hogged up all the ports you had. Well if you had ethernet I can go from, say this is... actually there's my ECOM down here on the end I can go from the ECOM to a hub and I can go out the multiple panels, I can still communicate to my PC with it, I can communicate to other devices as well if I need to So I can network out to some other stuff as well so makes life easier, Plus again re-initiate the fact that with lower noise susceptibility using the internet versus serial cables plus increase in distances and we're probably going to hit up these same topics again and again but we'll try to if we get to the slide, to skip over it I keep referring to this 205, the 205 here I've actually got two ethernet devices in it. I've got the CPU which is all serial but then I've got an ERM which is the ethernet remote master. Stands for ethernet remote master, ok... its H2-ERM, the H means Host Engineering developed it, thats one of our partners the two means it is for 205 rack and ERM and also I have an H2-ECOM 100 down here now this 100 is actually going to a hub and all kinds of stuff excuse me... our newer products like the Productivity3000 which is actually a PAC, we've got some on the table over there and one behind Tom, but reach this one over here But if you'll notice, Tom is going to hold it up for you Mr. Camera Guy, TJ.. If you'll notice the CPU actually has ethernet, USB, everything built onto the CPU itself. You don't have to buy an extra card out in the rack so if you look at cost savings when he first look at a Productivity3000 you'll be like, Wow that CPU is a little bit expensive, but you're saving yourself a lot of money on communications and you're not hogging up a slot out in your rack, you have.. This real quick, here we have USB here's our ethernet we also use an ethernet type port for remote IO as Shane said and we also have two additional USB ports and on top of that we have this little green plug over here that will be RS485 which would be serial and above it is an RJ12 type jack which would be RS232 Alright, lets go to the next slide... so we're probably gonna hit some of this stuff again and again... Well, Serial PLC communications was the original. Ethernet didn't come out... Did we pull that slide out? The history of ethernet? Or do we still got it in there? I think it is still in there. Ok, we'll get to it then... I won't jump that far ahead.. But most common configurations include the PLC to PLC, you know, to device serial, and PC to PLC And trust me you can still use you know standard serial communications to your pc for programming I mean, easy way to go. You don't have to use... And some of our PLCs, thats all they support Say a 105, that is all it has. Our newer Click is strictly serial. Right, no ethernet capabilities. Correct... It's not that it's a bad thing, it's just, you know, ethernet makes life a little easier and its faster. But in some applications it doesn't matter and then you can see down at the bottom there, but you also, you can see our little example of the 205 going out to slaves and go into the next slide there Tom. Can you see the hodgepodge of wiring? Can you imagine sitting out there on the plant floor trying to wire up all this with a soldering iron and DV connectors? Takes a little... and... Basically that's very similar to the serial remote IO that originally was available on the DL205 product line. You can see all the specs for it, but the plus side is you have long 3300 foot, so you... But, when you max that out that's it, you're done... But you got 232, 485, 422... you see all the specs there. Go on to the next slide. Ethernet Communications. There we go! There is your history. It was actually developed by Xerox in the 70s. Were you around then? Okay... Go out and do a Google search for ethernet, you'll popup all kinds of stuff, but you can the history of it. Its was pretty interesting, some of the terminology and why they actually came up with this but it was Xerox, I believe they said they had a common printer in the office and they needed away for everbody to share it, right. So that is how it came about. Actually, I was there when that happened. I, at one time in my career, was a Novell Network Administrator. everything was IBM token ring with coax cables and 'T's and terminators and everything... And then all of a sudden we realized we actually had, in the office area, a bunch of twisted pair wires that ran to everybody's office with telephone, and there was some spares in there and all of a sudden we saw ethernet and we started use network interface cards and PCs back to a mainframe, and we were able to utilize that twisted pair of wire that eventually became to be known as ethernet protocol. Cool. Okay... "Speeds" - you can see the specs on the speeds, it is a little bit faster... "Distances" - The thing about this is, we don't have that in the spec on the slide, but one of things distance is What is it? A 100 meters? Right? I forget what the conversion is... Couple hundred feet... 300 and something feet? but that's the distance on ethernet but if you need go further than that you can use a repeater or a hub/switch and you can actually tag off of that again Yoy can keep going with it. Right. okay next slide. "Industry Communications" In that regards, one of the advantages of ethernet and everything... I mean they're there are some air checking and everything with serial type communications but ethernet allows more air checking, there's more redundancy in sending packets of information and higher speed... lower cost because you're dealing with twisted pair type wire, small gauge... there is easier connectivity, with the serial type connection, even though in our case with our serial connectors we use RJ12, which is pretty straight forward. It's very similar to the RJ45, but when you start getting into serial type connections with the DB9 type connectors and you have to wire them up, it gets a little more complicated Next slide, what do we got? Basically, we're just showing two variations of ethernet and the only reason I think we bring this up is we're just trying to show how easy it is verses the serial... Yes... You saw the wiring configuration for serial. The ethernet, its pretty straightforward. You've got straights and crossovers. And sometimes it get a little confusing... I guess the best way for me is to either try to remember if I am sitting here with one of our ECOM and a PC... And I'm trying to communicate to the ECOM to do some programming to the PC, and I want to go direct, because maybe I don't have a hub or a switch then I need a crossover. Right. If I do have a hub up there and I go from the PC that would be a straight connection out to the hub or switch... and we will call it a switch like our Stride switches then another straight cable to go from the switch back to the ECOM on the switch or in the case of the Productivity 3000, I can plug directly into my CPU. "Products" - So we've got the Productivity 3000, we've got the Stride ethernet switches, the C-more, like what's behind me... Now real quick on the C-more any of our C-more panels, not all of them, we have some lower end, but used to on some of our older HMIs you could put ethernet on 'em but it was an optional card that you had purchase and put on the panel now with I would say about 80 to 90 percent of our C-more panels, if you buy the panel it's already built into the panel and so if you weigh it it out, it was actually... these panels are cheaper than our old ones are and they actually have ethernet capabilities built in. So save yourself some time and money all at the same time Continuing... We are showing the EBCs and ERMs we're gonna talk about them a little bit. Again, you know, the drives with the E-Drive Interface Card and we don't want forget our Terminator line either. Nope. The cool blue stuff. Now we talked about ERMs, what does ERM stand for. What does EBC stand for? You're the expert in that area. No, I'm not. If I have to guess, EBC is Ethernet Based Controller Is that right? Pretty close, yep. And ERM is Ethernet Remote Master. Ok, I'm learning. So yeah, an ERM is a master and it has to talk to a slave which is an EBC I'm not sure what examples we'ed put out here And I'll apologize, I've jump around on some of these slides that I forget which ones are which but the EBCs can be used for multiple things like for instance, I've got a master rack in my hand, or on my leg, and a slave rack in my hand this actually has an EBC and my ERM is going out to one of the Stride switches and it's talking to an EBC so this rack sees this was a slave. Now the EBC actually goes in the same slot that a processor, CPU, would go in, and... but the EBCs don't have to only talk to ERMs, you could use these in a different application where you were using some kind of computer based control like... Yeah, PC based control. like Think and Do or something like that... you'd have your computer talking directly to the PLC hardware and you'd use an EBC for that The one thing I think's really nice I can be set here with a DL205 with, let's say, a 260 CPU with an ERM. Right. Correct? correct. I can talk out to a remote base with an EBC module through a hub or a switch, probably a switch but I... In this case its a remote D2 type IO rack, but I can also use the Terminator, which Shane is holding over here so I can you field IO, which is nice because I can stack that up all over the place and actually hang that out there and be talking to the 260 CPU out to it The EBCs we offer those in flavors of the 205, 405, and the Terminator. So yes, an ERM, an Ethernet Remote Master which we make those 205s and 405s an ERM can talk to a 205, a 405, or a Terminator, or all above at the same time, you can use all those out in your rack... And again everything is interconnected with relatively inexpensive ethernet type cable The E-Drives and then what was the last one we had there? The Terminator IO. Terminator is sort of dumb IO. There's no CPU to put in those but there's all kinds of different communications and one of them is the ethernet and this next slide shows a little bit more in regards to some of the accessories that we have available for ethernet. We've already talked about Stride and the different flavors in it. One of the other industrial switches we have, we still sell. Shane is holding it over here. Here is the ESWO5U, thats been around for a while. We actually... I don't want to talk price too much, but I remember when that switch first came out it was something like $495 at that time... Maybe not that high.. Or even $272 somebody is going to say that's expensive compared to a $15 hub that I can go to RadioShack and purchase We always bring up that you'd use this in an industrial application where you'd have an enclosure out in a factory where it gets hot its rugged and withstands the environment and everything. And if you look on this one, it could be mounted a couple of different ways. It could be screwed to a a panel or backplane, also it's got on the back, its a little easier to see there, but its DIN rail mountable as well and yeah, this was our first ethernet.. industry ethernet switch that we were selling. People were, "Why should I buy that?" Well, of course, we have to give them the switch versus hub, but also the ruggedness. Vibration was one of the biggest killer of hubs I mean you can put a standard, you know, ethernet hub in your cabinet but if you've got a machine thats hopping around or vibrating or humming, thats gonna come apart where as these are actually made to withstand vibration and high temperature. We do carry, for little applications, applications were you can use a simple type ethernet hub, we do sell that with the cables too. Most of the time, I think our customers buy those because they're first getting into our products and are using let's say, hopefully, new Productivity3000 with a C-more and they want to set everything up with their PC right there on their desk where they can program both of them and have them connected up with the software and everything. So in those cases they might use a simple little hub with the cables. Next slide. Okay, this is the PLC Ethernet products. Like I said, we talked about the ECOMs now we do have... we have up there HX meaning we have them in 05, 06, 205, 405. So the 05, can put one option card in it. So you could put an ethernet card in it. The 06 actually has four options lots. So you could have... You could actually put four ethernet cards if you wanted to. The HX-ERM, so we have the ERM, Ethernet Remote Mastersm you have this for 205 and 405. and then HX-EBC, which, like we said, 205, 405, and Terminator. I think this next slide just gets into, and we'll go through it real quick, specifications. We're just showing it and all those are also available in a, I'm sorry I shouldn't say all of them, the ERMs and the EBCs are also available. They're not used a lot, but they're available in a fiber-optic version But, we show all the specifications for the ratings on it and throughput. You can find that on our website. "Configuration Options" - you've got a couple different ways IPX, TCPIP, all kinds of stuff you can get heavily into the ethernet communication protocols. You've got DIP switches you can go in to set up you can name... It's been awhile since I've set up one of these. I'm to set them up from NetEdit with in the software but I kinda remember one time you can either software set it up, or as this slide is showing, you can also set the address. Which would be the mode address with a DIP switch Don't ask me what, I have to break out pen and paper to figure those out "ECOM Software Configuration Option" Like Tom said, NetEdit. And tell you what I'm gonna do guys. If ya'll can go ahead... Switch over to... Let's see if I can minimize us a little bit so it can fit... There we go, its a little bit better. This is DirectSOFT... This is our DS Launch. You can get that with DirectSOFT. and actually, we have free DirectSOFT its like a play with version. A 100 instruction version. Yeah, so you can actually, get this and go out and play with it but inside of the DS Launch, there's a couple of tools and one of them is gonna be NetEdit. We can go here. Go to NetEdit... and open it up and it actually goes out sees what we've got here in our office now we have unplugged from the company network so we're not pinging everybody's office We'd see so many pieces of equipment but it shows that we've got a 205 EBC, a 205 ECOM, and a 205 ERM within NetEdit and now NetEdit is only going to show us the DirectLogic stuff right? to show us the DirectLogic stuff right? Correct. It's not going to see the Productivity3000 but you can go in and and do all kinds stuff here. Make some changes and what not. That's the NetEdit and it's also a free download if you just want to go get just NetEdit something else we talked about was the ERM workbench. I'm gonna open that up. and so if you're using This is just a comparison of old remote IO which that used to be my specially when I was in Tech. verses the ethernet remote IO, which is just a walk in the park compared to the old stuff. open up the ERM workbench and I say, okay, I'm on a hub I have got an ERM in my lap and I've got a EBC right next to me. and we are going to say, its on a hub. Yeah, you sure it's on a hub. Yes it is. and it says okay here's the address found. Well if I pulled that ERM out, that address would actually be printed on the label on the side Its like a MAC Address on a regular piece of equipment and also it says you can flash the error light. When I do that, there's an error light on this ERM, it actually flashes and I can see I've got the right one. Hit ok. and it goes out and says okay there you go now this is the input you've got and this is the output you've got. And I'll look over and sure enough, that's exactly what I've got. I can either remove something or rescan it and when I go to the next step it actually asks me where do I want my inputs and outputs to start. This is the part that I like. This is really nice. Especially the analog cause you can say I want it to start at wherever You don't have a manual, you can actually go through and start scrolling up and down and you noticed that I now have my input starting it x400 or I can go back and put them at X300 which is good if you have say this is my third slave rack I might want everything starting at three hundred the fourth rack at 400, but you don't have to. and if you're not sure what you've got. PLC Memory Map and you select whatever process you've got and it will tell you and as I said, all of our manuals are on the internet if you don't have one but I would highly suggest grabbing a printed manual any of the times you grab any of the PLCs and it says everything, here it is, it's all setup, ready to go... I can write to the ERM, which I already have written to it, so I am just going to cancel it. That's ethernet remote IO set up. That's it. Done. Took me 30 seconds. I'd still be sit here for a couple hours if I was doing serial remote IO. Yeah. Tell you what, let me go to... just real quick we have a slide in here basically we're showing Before the IBoxes... the IBoxes makes it a lot simpler. some ladder logic programming that allows communications between devices But, right after this I think we get into our little speed demo. Right. That Shane is gonna demonstrate to us Whoops, what happened to our speed demo? Maybe we don't have demo listed, but that's ok. I think at this point we're gonna talk about it right here. Yeah, then we'll go in to the customer applications Yeah, but like Tom was saying, on that one particularly networking... if you don't have DirectSOFT5 the example on the left hand side of that slide there you see, you actually gotta write some code you've got to know where you know modules are placed at, and what not... How many, you know, how much you gonna write... How many IO.. With the new IBoxes, you can just do it all in one instruction. One instruction. If I get a chance, I'll show that. Alright back to the DirectSOFT, real quick. We're at the DS launch and I've got a couple links here... Now just for kicks and fun here, we're gonna connect up to our 260 at Automation Talk and its an ethernet. You're connected up how? Ethernet! Ethernet? Actually, you know what. Let's... Back up? Nah its alright... Okay. Oh, yeah I did some stuff earlier but... Tips, if you're not familiar with DirectSOFT5 it gives you little tips. I'd say, you know Bruce Perry, when he comes in here gives the DirectSOFT seminar He says, you know, take a minute, when you have time, to go through these he's like, When DirectSOFT5 first came out, you know, the engineer wrote it there's a lot of little niches they know about that a lot of other people didn't know about, even the guys in tech we're like, "Hey I didn't know you could do that" So go through those if you get a chance Alright, so we have a little program written inside here and basically what we're going to do is just show you I'm gonna go to debug, all status on. I'm gonna go to my PLC and go to link setup. And you can see what, up here... Yep, it shows up! we're at a 120 some odd... Transfer rate. Right, per second... 130... and you see how many transfers we've done this is basically what means PLC to the computers is talking. DirectSOFT to the PLC is talking back and forth So if we were doing some kind of, captured data or something over ethernet and... Right... we wanted to, the common term is poll. Sure... this would show us how fast we could collect that data. Right. And for instance let's say if you're using DataWorks or one of those products like that, yeah... You're polling a bunch of information, analog information. Errors, all kind of stuff like that, PID, whatever, and you're throwing it in some kind of spreadsheet or database. It's gonna hog up the network pretty quick. Right? Right. So if you see there, 120 and some odd. And I'm gonna exit here and I'm gonna go to PLC... Disconnect... I'm actually going to close this out. We're gonna come back and we have serial communications here still First you need to... Yeah, thats why its red. Its not plugged in. Im gonna plugin in the serial communications and let's see if it comes up or give me an error again Sensing... And it should bring up the same project... When it gets around to it and we can actually go out here and create a new COM link, I wanted to show them how to do that as well. Okay. Looks like, possibly, because we had that down. Yeah, I shouldn't have ever unplugged it but our IT guy was in here messing with the computer right before the show Be careful, our IT guy the one engineering too. That's alright. No, we don't want tell Microsoft about it, its not any of their problems microsoft about its own problems Let me try this real quick... Actually, I wanted to show them how to create a link. So lets see if we can create a link. Man, our IT guy must have killed my computer Tell you what... Lets jump over to... What I was gonna show, Tom, was... Earlier, you know, we showed it as a 130 transfers per second That was through ethernet? Yes, with ethernet and if I went in with the same connection, serial. Basically, same PLC.. everything... The only difference was that I was using serial communcations and serial cable. The transfer rate was like 9 and 10 per second So it's, you know, more than 10%. Still good enough for programming and stuff But if we got into any kind of high speed, I'll call it data.. trying to capture data and everything you know might bottleneck us a little bit Right. Alright guys, if you can go back. I've actually pulled up the Productivity3000 let me see if I can fit this. Nope... Let me see if I can fit this inside the screen. Sorry, we're using a capture box so everybody can see. alright I am offline and I'm gonna go out and look for a PAC Its tough to say PAC instead of PLC and it's going out and looking to see what PACs are out there. Looks like you have two choices there. and if you look and see, let me slide these over just a hair. Oh, I see. One's a USB connection which we do have a USB cable plugged up between the PC and the PAC Which is cool because the Productivity3000 has USB connectivity I mean everything's going on USB pen drives and everything else USB, USB, USB, right? Right. I'm not positive, but I have not seen any other PLCs with USB connectivity and neither have I but you can plug directly from your PC to the Productivity3000 with USB. Connect up and you can program it like that or if you wanna use ethernet, it's built-in. So I can select that as well. and you can go in a make changes to whatever you want to with it as well and we'll open up, and hey, look! I'm online with it with USB because I like to use USB, its so easy. Since we're on the PAC, we talked about the 7 ports on PAC I'm jumping around a little bit here, but the whole talk show today is in regards to ethernet. Real quick, wanted to explain again on the Productivity3000 on the CPU we can do ethernet for our communications, we also use ethernet for our local IO explansion. So we can actually take from the base, from the CPU to a remote slave unit with ethernet cable. Again... and then also should mention on the PAC, since we talked about USB we could also do local remove with USB type cable and... Something else... What's in front of you, Tom. We didn't talk about those at all. Our little panel We didn't have these on the slides, but since we're talking about everything ethernet RJ45, we also have some bulk head type panel connectors we can use that are waterproof and stuff and everything. Let me bring this one over here too. With these, if you have ethernet on inside your cabinet you can bring these on the outside. So if you wanna plug up with a laptop with ethernet capability you could do that to program the units and everything I just wait for the day when they start selling some firewire ones, because thats what we use here in the video world is firewire and USB, but firewire is even faster. were going to go ahead and we've got a couple of customer examples like I said we haven't done that in a while the first one is American Boa, they are actually around the corner here from us in Cumming, Georgia and what they do is they make a lot of metal piping, flexible piping some if it is for the auto industry pretty cool stuff but what they had here was a test stand that ran through test the pipes, and what they had was a local PLC and it would run batch tests and used to what happened, every hour one of the managers with would have to run up there with the clipboard and get all the information and then they updated that. They would have have to run out there and you collect the data from the the system but they could do with digital data you know a CD or USB pendrive then what they did was the updated it and they installed ethernet and they were able to run ethernet from the test panel back into the office and they use DataWorks which we sell here and with DataWorks they were able to sit anywhere in the office and pull all the batch testing and see what's going on make sure that all the products are okay Actually, the old way they had to run out there with a laptop and get the information every hour I can imagine that was a pain but yeah so saved them a lot of time and a lot of money and then anybody you know if Joe Bob is not there that day you don't have to worry about him having to run out there with the laptop. Because that's his laptop and he's only one that can connect up to it now if he's not there anybody can go in and then pull the spreadsheets and look at the data cool okay the next when we got is Lockhart Hydroelectric Plant now what this one was is that they were revamping the power plant and what they did was when they revamped was that they had different locations upstream and downstream and they needed to turn on different stations as they were revamped or you know retooled and they added ethernet and were able to communicate with HMIs on all the ethernet and they had HMIs that would actually go in and they could they could select ok we want to turn off this one until it's redone or retooled and once it was all retooled they could use that same HMI and actually turn on the next, you know power up the next section of the plant so that saved them a lot. They didn't have to worry about enabling, disabling, unwiring, wiring and what not but they could just do it all through the HMI with Ethernet Communications Like I said, the PLC links were already all there they were already all available and it was like a seamless operation when they were ready to go I know we don't show it up there and we're out of time and were at the at and of our show today, but one other thing I'd like to mention really quick, I am kinda pluging for the Productivity3000, but besides using ethernet type cable for remote slave type IO. Also, if I can grab it over here and show it. Cameraman. Oh yeah, our E-Drives. One of our E-Drives that we can connect up to a GS Drive or a Durapulse Drive the PAC, or I should say the Productivity3000 also has the ability to run an ethernet cable from one plug here, this is actually RS485 that goes to the drive, but we can hang up to 64 GS type drives off of these E-Drive interface cards and auto-configure 'em on directly from the Productivity3000 software just another one of our ethernet abilities and features. And I think that concludes everything I had to say at this point. Yeah, whats our next slide Tom? I think this is our... Q & A Well, I'm gonna let Tom look over the computer. Like I said, we swapped sides for this seminar. And if we have any questions... if not, I know we have some people had asked prior to the show. When you sign up for the show, your about to ask us some questions or tell us some stuff you wanted to see. Tom? You see anything over there as far as questions? I don't see any but here's some that I think have come up over the years. The first question I have, "Can there be multiple ECOMs in one base with just one PLC CPU?" You can... I forget exactly what the limitations are, but you can have multiples Specially if your doing, like, you know, master to slave PLC to PLC communications you might want to tag that on its own little network and have another ECOM and use that ECOM for communicating to the pc So if you isolate your network, especially with the ethernet remote stuff the ERM and EBCs You want to isolate your networks, we didn't mentioned that earlier... You don't really want to have your ethernet remote stuff on the same network as the rest of the plant. I mean it'll work, but it's not suggested. You can't hog up a lot data, or you are going to slow everything else down, bottleneck it. So yeah, if you want some faster communications you wanna isolate your networks. Yeah, put multiple ECOMs and one ECOM going to one set and one ECOM going to another I think we've just answered this question.. "Can DirectLogic PLC ECOM connect via FDs?" And the answer is no, but with the E-Drive interface card and an ERM module through a switch we can already communicate that way. So I've already answered the question. We have time for one more question. I don't know if this is a simple one or not. "How do you connect EBCs to PLCs for Ethernet Remote IO?" I think you covered that. Yeah. So that was covered. Nah, I'll meantion it again. What was the question? EBCs... to PLCs for remote IO. Use an ERM. Okay. Exactly. And ERMs... ERMs are the best of the remote IO stuff with 205, 405, and depending on what you want for your slave. With the Productivity3000 you already have... Its remote IO, but it's actually like Tom said, it's ethernet remote IO. Its a little bit different communications but it takes a standard ethernet cable. The remote IO is already built into the processor you don't have to buy anything extra modules it's already there. So when you buy the processor you get the free remote IO, whether you use it or not. Take advantage of it. Ethernet communications straight to it to the slave rack. Alright, we'll stop with the questions there, but if you have anymore go ahead and ask away and we'll always answer via email "Information Resources" - There's a lot of stuff on the internet. Went out there and looked. We're gonna send these via email, so don't worry about jotting them down. These will be in the email saying thanks for coming but the ieee.org Institute stuff, The Industrial Ethernet Book. We have a lot of information online. Yes. There is some nice ethernet manuals that we could cover. If you don't want to purchase one a printed one, you can go out and download a free one off our site. and our last slide. And if I could get our engineers to wrap everything up on their end back there behind their sudio desk. I want to thank everyone for coming in and watching today. you can see that we had a good crowd. I want to thank Tom for coming in and helping me out with this again. Thank you for sharing. We tag team these and have a lot of fun. You couldn't find a better job. Let me see if I can find the ending here... Thanks for coming in, hope you learned something.
