PLC S7-1200 Siemens is one of the most famous PLCs in the world, it supports very diverse communication standards such as Ethernet, Profinet, RS232, RS485… and today plc247.com will guide the you use it to connect to the Autonics TK4S temperature controller.
We need to use more Module S7-1200 CB1241 (or S7-1200 CM1241) so that the PLC has RS485, along with that, the TK4S must also choose a model that supports RS485.
Siemens S7-1200 & Autonics TK4S “Wiring Diagram”
TK4S Modbus-RTU Parameters Setting
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 (Address No.1)
- bPS = 9.6 (9600bps)
- Prty = EvEn (Parity check)
- StP = 1 (Stop bit)
- rSy.t = 20 (Response time)
Register Address for Set Temperature
- Address = 0000 (hexa)
- Func = 06
Register Address for Temperature Monitoring
- Address = 03E8 (hexa)
- Func = 04

Hi PLC247
can i know if you have SCL programming Tutorials Sir or files for basic SCL tutorial. and I hope that even STL Programming can be a big help in my studies in the Automation industry.
thank you very much
Now i only make Ladder and FBD tutorial sir.
hello
how many termoregulator(autonics tk4) can be connected to the plc 1200 throghe the modbus with single signal board
maximum 32 sir
