I've purchased two CLICK PLCs, a C0-10DRE-D and a C0-11DRE-D, two C0-01AC power supplies, two C0-16ND3 input modules, two C0-16TD1 sinking output modules and one C0-16TD2 module. The CLICK has far surpassed my expectations. Fearing that the CLICK might not be fully adequate after I learned how to use PLCs, I also bought a Productivity 1000 starter kit and some extra I/O. Although the Productivity 1000 has "big iron" capabilities, the CLICK PLCs are easier to learn to use. So far, they do everything that I need to have done. I use one as a front-end to a CentroidCNC Acorn CNC interface. It easily handles the mismatch of various servo motor signals so they appear to be uniform to the Acorn interface. It also sequences power supplies either manually or automatically, depending on settings from an Android Tablet HMI, generates customer servo enable signals so that the servos do not let loads drop if an error occurs, and various other tasks. Although it is the least expense part of the machine, it handles more work than anything else except the Acorn board. In addition, I have all three PLCs connected via a Modbus TCP network and the two PLCs that have RS485 ports talking to each other and to an arduino that monitors CPU temperatures in some high power server computers that I use. I had a box full of Arduinos ($25 each), some DS18B20 temperature sensors ($2.00 each) and some RS485 LC ELECTRONIC interfaces ($1.00 each). With one Arduino, four sensors and one RS485 interface plus a few terminal blocks and a DIN rail mounted rack of relays to handle brute force power control to the servers, the PLCs monitor the Servers' temperature, warn me if temperatures are getting too hot and shut down any Server that has exceeded a set-point, Using AutomationDirect's CLICK and P-1 made the project a breeze. The price for the PLCs was far below what I expected to pay. Service was great. Shipping was free. When I called support before placing an order for the first CLICK, I received curteous and friendly help. All in all, it's been a pleasure doing business with AutomationDirect.
