deference between DCS and PLC including date processing and
architacture.
Answer Posted / rakesh kumar .n be
PLC will have faster date processing then dcs..... PLC will send the date 50ma while DCS will 500ma.... it is not the accurate valve it is the bacic difference.
according to the Architecture PLC is easy but DCS is difficult, but DCS is good because in DCS we use HPM->HPMM->FTA->FCS->Field (redundancy is good in DCS)
