Your tuning tool, for example, makes your use very practical. Some applications, however, are very simple, and don’t need all of the potential of the intern S7-1200 PID controller. For this very simple application, the follow “lean” version of PID controller could be a choice. He has a clean list of parameter that makes your use for simple application, that doesn’t needs of tuning tools. He has an auto detection of its call time, so he could be place in any cycle or time OB without any special adjusts. Your open source could also easily adapt for special uses.

Manuelestevez Posts: 1 Rating: (0)	Preçado Pegaia. I have used the PID Lean with TIA Portal V10, but in order to use with TIA Portal V11 (including PID_V11.zip), the FB1 PID Lean compiles fine, but gives the following warning on the variable #LMN in the segment 14, used on three occasions in this segment: The declaration "output" from the current parameter is not in accordance with the statement "Input" formal parameter' "". Question:coulderase the segment, not using Manual mode with the PID

I think there is a different if you use STEP 7 V11+SP1 (with or without Upd 2) or V11+SP2 or only V11. If you make a project/program with V11+SP1 first and you go back to V11 (without SP1) it is possible that hardware parts are missing. With best regards Cicero
