Autonics TK4S & Weintek MT8071iE “Modbus-RTU” Tutorial

Written by

Hello everyone!

Before that, made 1 Series of instructions for using different devices to control connection of Omron Temperature Controller E5CC via “Modbus-RTU” Communication.

Today I would like to continue to guide you to control another temperature controller, Autonics TK4S-Series. And first I will use the Weintek MT8071iE HMI monitor to connect the TK4S control directly.

TK4S & MT8071iE “Wiring Diagram” use MT8071iE COM.3 port along with connectivity (8bit /Even /Stop bit = 1)

Autonics TK4S Communication Setting

To set Modbus communication parameters for TK4S we need to go to Parameters 4 (Par4) of the clock to set the following parameters:

+ PAr 4

  • AdrS = 1 (Address Slave)
  • bPS = 9.6 (Baudrate)
  • Prty = EvEn (Parity Check)
  • StP = 1 (Stop bit)
  • rSy.t = 20 (Comm. Response time)
