Hi all,

Could someone tell me that I can take FB standard for PID control
for speed of a motor where the point of reference be the current of another engine.

If anyone has an example I will be very helpful.

Thank you very much.

before we use the FB 41, Shall the input and output word be scalled/unscalled first?

dear Mr hosseini,

yes you re right. im going to use analog input as set point. The range is 0-10V signal.

i dont have any sensor to simulate the PID control system, so i use (PIW 256) As the setpoint signal connected the 0-10 V - external variable DC power supply.

Then i use PIW 258 as the "PV_per" signal. The PIW 258 directly connected with PQW 272 "LMN_per" signal, which is outputting 0-10 V from its module.

i have attached the OB 35 on my previous e-mail, now i upload the OB 1.

really need your advise or correction for any mistake on the code.

Dear Simatix,

Please check the solution in attachment.

Best regards
