Dear Experts
Could you please help me?
I read quite some discussions about PLC connection with PLC in the loop, but it was hard to understand all options completely.
I would like to do a test environment in Matlab and more preferable in Simulink for a PLC Code.
I have my existing, large PLC code with many input / output signals (not small data rate), which shall be given / received by the test environment.
The test environment shall behave like the counterpart-system of the PLC and additionaly log all data.
Additionally I have my code on a PLC, which runs in 28ms.
Now I want to test the code (SIL=software-in-the-loop) and the PLC (HIL=Hardware-in-the-loop).
1) SIL: What options do I have?
a) SIL environment of PLC (e.g. Beckoff)
b) SIL environment in Matlab for PLC Code?
c) PLC Controller? (https://ch.mathworks.com/help/plccoder/ref/plccontroller.html?searchHighlight=plc&s_tid=srchtitle)
d) ...
=> What option would you please recommend, in which case?
=> What option would you please recommend, for my case?
2) HIL: What options do I have?
a) Deployment on PLC (e.g. Beckoff): I could either do Code in Matlab/Simulink/Stateflow and genereate PLC Code by Simulink PLC Coder or code it in PLC Code directly
=> How do I get the logged data back in Matlab to see the result and check the acceptance criterias?
b) OPC communication
=> Is a sampling time of 28ms fine?
=> Which data rate or amount can be sent / received by with 28ms cycles?
=> How stable and robust is the connection?
=> What matlab / simulink tools and hardware do I need to have?
c) OPC Toolbox (sames as OPC communication)
=> Is a sampling time of 28ms fine?
=> Which data rate or amount can be sent / received by with 28ms cycles?
=> How stable and robust is the connection?
=> What matlab / simulink tools and hardware do I need to have
d) MODBUS-TCP/IP
=> Is a sampling time of 28ms fine?
=> Which data rate or amount can be sent / received by with 28ms cycles?
=> How stable and robust is the connection?
=> What matlab / simulink tools and hardware do I need to have?

=> What option would you please recommend, for my case?
=> Is there a resonable order of the options to start to try rising my testing?
Kind regards & Thank you very much
