Hello, in the previous post plc247.com showed you how to use MicroLogix 1100 to connect to Omron E5CC, today plc247.com will continue to guide you to connect to another Temperature Controller, which is Autonics TK4S.
MicroLogix 1100 PLC has built-in RS232/RS485 port, you can plug the power cord directly into the MiniDIN 8P port, or use the 1763-NC01 extension cable
MicroLogix 1100 & Autonics TK4S “Wiring Diagram”
Note: A terminal resistor is required if the communication distance is long
TK4S Modbus-RTU Communication Configuration
To set communication parameters for TK4S we need to go to Cluster Parameters.4 ( plc247.com choose 8bit/Even/1bit communication type).
TK4S >>> Mode >>> PAr.4
+ AdrS = 1 (Modbus Slave)
+ bPS = 9.6 (9600bps)
+ Prty = EvEn (Parity check)
+ StP = 1 (Stop bit)
+ rSy.t = 20 (Response time)
Note: MicroLogix 1100 Address = “VFD Address (Dec) + 1“
Register Address for Set Temperature
+ Funtion Code = 06
+ Address = 0000 + 1 = 1
Register Address for Read Temperature
+ Funtion Code = 04
+ Address = 03E8 (hex) + 1 = 1000 (dec) + 1 = 1001
