Communication between DCS and electrical backoffice
Thread Content
Can the motor signal sent via communication be used to participate in process interlocks through DCS configuration?
It is not recommended, as there is strong electromagnetic interference in the electrical system, which can easily cause communication instability. Monitoring is okay, but control is not necessary
It’s completely possible – transmit the motor speed and current, as well as the isolation barrier
It is feasible, but in principle, hardwiring is generally used to connect to the DCS in order to participate in process interlocks
