Hi, you have to call you fc3 in OB35 and then set correct cycle time. After PLC Restart you have to set COM_REST for one plc cycle. Check manual for Cont_C and this FAQ for more Details: Where can you find descriptions and examples of PID control with FB 41, FB 42 and FB 43, and SFB 41, SFB 42 and SFB 43?What should you watch out for when calling and assigning parameters to the controller functions in function blocks (S)FB41, (S)FB42 and (S)FB43?Regards, Towome |
