We will now look at communication between the Productivity 2000 PLC (Modbus TCP Server) and Node-RED (Modbus TCP Client). Node-RED is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that uses flow programming. Minimal coding is required; you can see the program flow visually. The best thing is that the software is … Read more
Using Modbus RTU (RS485), we will connect the XY-MD02 Temperature and Humidity Sensor to the Click PLC. The Click will be the Client (Master), and the Sensor will be the Server (Slave). This is an ideal sensor to place in a panel to ensure that the panel is within a working temperature and humidity range. … Read more
