Hello everyone!
In the previous post, plc247.com showed you how to use MicroLogix 1100 PLC to connect and control Omron E5CC by Modbus-RTU RS485 Communication.
Today plc247.com will continue to guide you to connect another temperature controller, Autonics T4KS. MicroLogix 1100 PLC has a built-in RS232/485 port (you can connect it directly to the MiniDin port or use an extension cable 1763-NC01)

Autonics TK4S Modbus Parameters Setting
In order for the Autonics Controller TK4S to communicate with Modbus RTU, we need to set the communication parameters as below:
TK4S >>> Mode >>> PAr.4 (Parameters Group.4)
+ AdrS = 1 (Slave Adress)
+ bPS = 9.6 (Baud Rate)
+ Prty = EvEn (Parity Check)
+ StP = 1 (Stop Bit)
+ rSy.t = 20 (Respense Time)
Register Control Address
>>> Temperature Reference Address = 0000 / Function = 06
Register Monitoring Address
>>> Temperature Present Address = 03E8 (hex) = 1000 (dec) / Funtion = 04
