The P2-550 is an excellent processor that compares with the AB Compact Logix processors, but you can build an entire system with I/O for less than the cost of just their processor. With scan times in the microseconds, it will handle the most demanding tasks with ease. The programmable display helps with diagnostics and troubleshooting. The other nice feature is that they just connect - no endless communications issues to get the processor to talk with a Laptop, or other modules, it just works. The software is great, with functions line "Average" or "Min/Max", it saves a ton of time when you have to deal with complex programming issues.1 person found this review helpful.
This is my first time purchasing a P2 system. We have been a long time user of the D2-260 and switched over to the P2-550 with any projects starting in 2018. It's a fantastic product. In conjunction with the three day course made the transition easy and straight forward. I would recommend the P2 system to anyone.1 person found this review helpful.
This is a powerful and easy-to-use PLC but has it's quirks. While the controller is quite solid the weakness is in the software. Coming from a mostly AB world, not being able to "sketch" in the logic before assigning tags to each instruction is inconvenient. Also, the completely schizophrenic logic to the editing keys takes a bit of time to get used to (e.g. in most windows programs and *parts* of the Productivity software, F2 means "edit", but not in the ladder editor it means place a NO instruction here). Also, I noticed that the "rung examples" for the instructions in the online help is less than illustrative. If I were a neophyte, I would think this is less than helpul. That being said, it would be hard to find a more capable PLC for the price.
This is my goto PLC. I have used it in simple machine automation with discrete I/O, using the serial port to communicate to DS2, Durapulse, & Yaskawa drives, as well as setting up generic Ethernet clients in the CPU to communicate to Universal Robots and Cognex scanners and cameras. I was even tasked to perform temperature control applications, one involved needing an expansion rack, and the built-in PID tuner was a lifesaver. The hardware configuration display in the software is very handy. You get a graphic representation of your PLC layout where you can click on any of the cards, and edit the tag names to the I/O right there. Personally, I prefer tagged based programming, where your tag is the address of the instruction. I think it makes the program easier to explain what each object is doing in its tag, instead of having to explain what a predefined address that was used is for. When I've had to use a non A-D PLC, attempting to connect to a fresh unused CPU to install the program is a pain. When the P2K CPU is pulled from the box, its default IP address is 10.10.10.10. I find this to make sense, than say, Allen-Bradley's use of having no IP address, and then having to use their awful software to give it an IP address. And speaking of software, unlike any Rockwell product, the Productivity Suite does not require a key, nor does it take over your computer, and make the boot up process as painful as possible. Finally, I have called A-D technical support for help on many of their products, they were always helpful, and got me where I needed to be, quickly. And the best part is they never asked our company to sign-up and pay for a technical support contract to provide this service. Automation Direct is the best.3 of 3 people found this review helpful.
This is a neat "PAC" with a quirky command set. It's inexpensive for what you get, but you do get what you pay for. First, the documentation is absolutely horrible. The hardware manual is ok, but the Productivity Suite documentation only exists in a windows help file---and the help file is almost not worth looking at!!! Navigation within the Productivity Suite is also a chore. If I start to enter something on a rung and it scrolls the rungs to the left, I cannot scroll until I either enter everything for a given command or simply cancel. PLC software from the late 1990s is easier to edit ladder code. However, it's not all bad. The Tag Editor is decent and the autodiscover for hardware is terrific! So, if you are already familiar with the AD PACs it's easy to use. If you are a newcomer to the product line you are in for a scramble to find information or simply request assistance from AD.1 person found this review helpful.
My goto PLC. The quailty and performance is there. I have to use other brands of PLCs for one reason or another from time to time but this one is my favorite. Top 4 reasons I use this PLC... Small footprint, performance, great tech support and the software is by far the best out there. Everyone has a favorite and this one is mine. My second favorite is its bigger brother, but this one has so much hp, I don't have to call on him that often.1 person found this review helpful.
The Productivity PLC hardware is really nice. The latch to the base could have a little more positive action to it, but other than that, it is some of the nicest plastic PLC hardware I've used. Unfortunately, there is a bug in the firmware/software related to the bumpless transfer when switching a PID in the controller from manual to automatic mode. When I brought this to the attention of tech support, they simply replied with the standard "that's how it's supposed to work and we'll just change the documentation to let people know that it doesn't work like it should." I've worked with many different PLC brands and none of them show the behavior that the Productivity2000 does (nor should they). If you have an application that requires manual manipulation of a PID output by an operator in certain circumstances, I would avoid these PLCs. I won't be buying another until this issue is fixed. It's a real shame because I really liked just about everything else about these.
I've lost track of how many of these my company has bought and installed. We love the dynamic ability of them, the price, the ease and support of programming/troubleshooting, and the dedication that AutomationDirect puts behind them. These are great PLC CPU's!
Very easy to get started with, used for various applications including data collection, PID motor control with dancer for unwind applications, coordinating several drives. Pairs great with C-more panels to make projects easy to troubleshoot and adaptable to user needs.
This is an extremely powerful CPU for the money. Also the free productivity software is a breeze to program with as well as to connect to the PLC. I use to swear by Allen Bradley components and will never go back unless specified by the customer. I have applied the Productivity 2000 to many machines around our plant and plan on converting everything over time. We currently have approximately 10 of these around the plant and have never had an issue with a CPU.
