I recently used 2 Clicks in an assembly machine, with one plc per station. They are networked using Modbus on RS485, with a 6" C-more micro panel as the master for entry of data and settings. I can't say enough about the versatility and value of this little plc. Having 3 serial ports allowed me to use port 3 (485) for comm with the touchscreen, while sending serial commands to a stepper drive on port 2. I implemented job storage with 99 presets and other helpful features, and still had about 75% of the program memory left. I was concerned about the 8000 step limitation, but by using subroutines and efficient coding, it proved to not be an issue at all. The only issue I ran into was not being able to use text efficiently, like the other (3x or higher priced) controllers. There was just not enough memory to allow for Strings of any usable length to be stored. I knew there would be limitations, and it was more than an acceptable trade-off considering the cost of the controller in my budget-sensitive application. The implication was that my job storage was numerically named rather than allowing for a text-based name. Not a big deal in this application. I really liked that the Modbus address was displayed in the Address Picker. Very helpful. If you can deal with the limited instruction set, this is an outstanding value and punches way above its class.
Thank you to AutomationDirect for making analog I/O for the Click!
I have used the C0-11ARE-D, as well as other Click CPUs on many projects, including as a Modbus slave over serial radio link, simultaneously with local wired ethernet, and have never been disappointed. I used the RS-485 port to R/W registers in two VFDs, and used the ethernet port for Cmore and plant SCADA; no problems. The instruction set is small but adequate. You can make your own "Scale with Parameters" (SCP) instructions using Math and put them in their own subroutines. These "SCP" instructions can also be implemented to effectively pace pumps on VFDs for level control. I have done this many times with no issues. You can use the Copy instruction to convert integers to hex; hex to binary, etc. Comes in handy when using control and status words in VFDs.
only thing that i dont see is a way to let dhcp assign ip addresses. other than that, pretty cool.
I HAVE USED WELL OVER 100 OF THESE PLC'S OVER THE LAST 5 YEARS. I HAVE NOT HAD A SINGLE FAILURE. THEY ARE EASY TO USE AND SET UP. FOR THE MONEY I DON'T THINK YOU CAN FIND A BETTER PLC. OF COURSE AUTOMATION DIRECT STANDS BEHIND ALL THE PRODUCTS THEY SELL. THEIR PROMPT U.S. BASED CUSTOMER SERVICE TEAM IS A HUGE PLUS FOR ME.
Easy to program. Good value for my application.

These are great little PLCs. We have deployed several of them and have been very pleased. There are a few glitches/quirks with the Ethernet "send" command, but setting the scan time to a fixed 30mS seems to help, as well as using fixed comm timeouts. Overall they are fast, very easy to program and deploy, and so far are 100% reliable. I would like to see a few more instructions - for example, there's no "absolute value" instruction, but overall we have no problems getting these units to work for us. Personally I find them much easier to program than AB SLC/500's but that's just a personal preference. The free programming software is a big plus too.
I really like the CLICK series PLCs. However, these power supplies require separate wiring to the PLC module. It would have made sense to add the same DIN header on this power supply as the other modules, so it would connect directly into the PLC without separate wires. Then if you chose to use another power supply you could wire it in, but if you use the CLICK power supplies, no need for wiring to the PLC. It would have made my cabinets look nicer, and a bit easier to set up. Otherwise, this is a great system and this little power supply is great and a good value.1 person found this review helpful.
We use these for several applications. The Modbus port is great for connecting this to my Plant Monitoring system so I can see/track status of equipment from my office. Inexpensive yet powerful enough for many applications.
