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
The XY-MD02 temperature and humidity sensor uses Modbus RTU for communication. Modbus RTU (serial) works as a master (client) to slave (server) communication protocol. To add this sensor to an existing network as another unit number, you must set it up first. We will be using the Simply Modbus Master software in demo mode to … Read more
The XY-MD02 utilizes an industrial-grade chip and high-precision SHT20 sensors for temperature and humidity. This guarantees the product’s reliability, precision, and interchangeability. It uses the RS485 hardware interface with lightning protection and is compatible with the standard industrial Modbus RTU protocol on the protocol layer. The product combines MODBUS and ordinary UART communication protocols, allowing … 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
The Productivity 2000 series of PLCs has five built-in communication ports for easy connectivity to your PC or various industrial networks. Ethernet protocols like Modbus TCP can be utilized with the RJ45 port on this PLC. Modbus TCP is an open (published) protocol that uses the Server (Master) / Client (Slave) architecture. It’s a very … Read more
