Click PLC to Click PLC Communication RS485

This video will show you how to use Click PLC to Click PLC communication using serial RS485. This communication method allows you to control Click PLC remotely using Modbus RTU. By showing you this example, we hope to provide you with a better understanding of how this communication method works and help you to use it in your own projects. More information can be obtained at our website. This includes all of the links mentioned in this video. https://accautomation.ca/click-to-click-plc-communication-remote-io/ We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs. The send and receive commands have been covered before in our Click PLC Series, but we will look further at the timing of the communication. Detecting and correcting communication errors will be discussed and implemented. We will also create a heartbeat for the remote Click slave (server) PLC. This will allow the remote controller to determine if communications have stopped with the Click master (client). Wiring a pushbutton and some ladder logic code will allow us to time the throughput of each of the communication methods. CLICK PLCs were designed with simplicity, providing reliable control at a low cost and with little to no learning curve. This simplicity makes CLICK a perfect solution for small machines, home automation projects, pneumatic applications, or anywhere a simple system needs a budget-saving control solution. Building on the original CLICK’s simple design, the new CLICK PLUS PLCs offer the same practical control but with some surprising bells and whistles. Using the same FREE, streamlined PLC programming software as its predecessor, the CLICK PLUS PLCs provide no-headache programming combined with advanced capabilities like Wi-Fi communication and data logging.
