Practical Tips and Techniques
We will now look at the click plc modbus ascii protocol. This communication will happen in PLC ladder logic and communicate through the serial port (RS485) to a Solo process temperature controller. Modbus ASCII will be the communication protocol. Modbus is a communication method used for transmitting information over serial lines between electronic devices. The … Read more
The cmore EA9 HMI has an event manager that can be used to trigger actions based on various events. We will be adding a Click PLC to our headless RHMI cmore EA9 program that we created last time to communicate to the solo process temperature controller. The Solo will be connected via RS485 using the … Read more
The cmore EA9 HMI can connect to the Solo process temperature controller using the built-in RS485 serial communication port. This will connect up to 32 solo units back to the HMI for display and control. We will be setting up our headless RHMI c-more EA9 to communicate to the Solo process temperature controller. Using the … Read more
The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with either the RS232 or RS485 ports on this PLC. Modbus RTU is an open (published) protocol that uses the Master / Slave architecture. It’s a … Read more
