Hello xBigGx, There is a topic that discussed this issue in details,I suggest reading the topic and check if it helps: How can you prevent the PID Compact controller of the S7-1200 from switching off when the controller is switched off and on again and in the case of invalid process values? I hope this solves your problem, Hamid Hosseini |

Hello again, Thanks for the feedback. You can try "sRet.i_Mode" variable saved in the IDB corresponding to the loop.You can check if it works via a watch table and checking the current mode pllus status/error outputs.More can be found in online manual "Parameters State and sRet.i_Mode".
Also I suggest checking: TIPS for PID (FB PID_Compact) Best regards, Hamid Hosseini |
