Networking Protocols Interview Question:

What is the networking control unit?

Submitted by: Administrator

The Network Control Unit (NCU) is a field panel housing
electronic modules, terminal blocks, and signal conditioners
(pneumatic, linevoltageand electronic) all inside a single
enclosure.

The NCU contains the user-programmable main processor-the
Network Control Module (NCM)-for supervisory functions over
all devices on the local bus, and a combination of the
optional Digital Control Module and Point Multiplex Modules
to directly control field devices that wire to the NCU
termination blocks. This application installs all models of
the NCM(101, 102, 401, 200) into standard 1-Slot, 2-Slot, or
5-Slot base frames.
