THANK YOU it means the FC35 is used 14 times with the same parameters in all the program ? |

Dear MEDALI, Same parameters , I think it is impossible because different control loops have different dynamics and they need somehow unique PID parameters.To be sure, please check parameters related to each loop stored in the corresponding data blocks.You can check data for each loop while you are online to PLC.Loop parameters can also be changed via HMI. Make variable table for each loop like I did here(3-6-2012 9-06-32 AM.jpg) Best regards, Hamid Hosseini |

If we exclude gain(real), other parameters are of data type"TIME" |

Dear MEDALI, I have checked the PID parameter of your loop.For me a D parameter in order of milliseconds is really strange If D part is selected . Does your loops corresponds to this parameters work properly? Also,small integration time is somehow strange,But check the real loop performance. For tuning loops refer to this link: PID SELF TUNER

I USED S7-PLCSIM AND NOT A REAL PLC. |
