Dear Friends,
i am using Siemens S7200 PLC. my project is i have to control VFD through PID. i made the program and also it works.
but when i use this program to other jobs, that time i have to deleted the PID Block and i have to Re install PID Block one more time. then only PID will works.
My questions why PID is like that?
and also some times i didn't get PID output in the PLC. why this is also happened ?
can anyone please clarify on this issue.
Many thanks, please make reply on this issue...
