why we are using MARSHALLING PANEL? what is the role?

Answer Posted / kkrameshkumar

Marshalling means grouping of I/Os. Marshalling panel is
placed between the DCS system panel and field instruments.
In marshalling panel grouping of I/Os like Analog Input,
Analog Output, Digital Input, Digital Output and Pulse I/O
are done.From marshalling panel the I/O signals are
communicated to the system CPU/Controllers through
Isolation/Signal conditioners.

In marshalling panel we can easily identify the Input or
Output and easy diagnosis can be done in case of fault
finding.
