-
Weintek MT8071iE HMI: This is the HMI device you're connecting to.
-
RS485 Communication Port: The Weintek MT8071iE HMI has an RS485 communication port that supports Modbus RTU protocol. Ensure that the RS485 port is available and enabled on the HMI.
-
Modbus RTU Slave Device: This could be a PLC, sensor, or any other Modbus RTU-compatible device that you want to communicate with.
-
RS485 Cable: You'll need an RS485 cable to physically connect the HMI to the Modbus RTU slave device. This cable typically has two or three wires, depending on whether you need a half-duplex or full-duplex connection.
