[?]: Siemens PID FB41

Post by omar zedan »

Dear all
I use PID FB41 in OB35 (DB10) and in OB1 I move MW100 to (DB10.DBD10) PV, MW100 to (DB10.DBD6) SP,
posative edge impulse to (DB10.DBX0.0) start and false to (DB10.DBX0.1) Manual. and also move (DB10.DBW76) to MW200 output.
But the PID dose not work (the output will be 100% if SP > PV and the output will be 0 if SP< PV)
Thank you
