Hi Sir,
I am using S7-300/400. I am usually using FC 03 and FC04 to transfer (R/W) bool values by moving them DBs. However i want to R/W bool values directly to plc ( slave) from master yoko dcs. I configured FC 01 and FC02 in slave slide ( write to Memory M) and used function A0 and A1 in dcs side. I cant write directly to M ( from M300.0 with 10 byeltes).
Thank you very much for yours help.
