Mitsubishi HMI “Modbus RTU” Autonics TK4S Tutorial

Written by

In the previous article guided you to use Mitsubishi HMI to monitor and control Omron E5CC Controller through “Modbus RTU”, today will continue to guide you to connect to a controller other temperature is Autonics TK4S.

The model HMI uses is GOT2000 GT2505-VTBD with built-in RS422/485 port, and for Autonics TK4S we need to choose a Model that also has an RS485 port (project use model: TK4S-T4SN)

HMI GT2505-VTBD & Autonics TK4S “Wiring Diagram”

Note: Use a 100 to120 (Ω) terminal resistor if the communication distance is long

Autonics TK4S “Modbus RTU” Parameters Setting

Here are the Modbus communication parameters that we need to set for Autonics TK4S Controller

TK4S Modbus Registers Address

>>> Temperature Settings Address = 400001 (dec)

>>> Temperature Monitoring Address = 301001 (dec)

Mitsubishi GOT2000 Modbus Configuration

How have we set up the Modbus communication parameters for Autonics TK4S, set the same for Mitsubishi GT2505 so they can be connected.
