The electronic module contains the electronic components. It
is connected to the manifold and to the sub−base by means of
electric plug connectors.
With CPX field bus nodes the connections are fixed compo
nents of the module. The CPX I/O modules have various types
of connections.
The lower part of the housing of the electric modules is called
the manifold sub−base. Manifold sub−bases serve for the elec
trical and mechanical linking of the modules. They offer e.g. a
connection for supplying the operating voltage and/or load
voltage and transmit the operating and load voltages to the
neighbouring modules (see section 1.1.3). The mechanical
link between the electric modules is made via tie rods in the
manifold sub−bases.
You can replace electronic modules with sub−bases during
servicing without the need to dismantle the CPX terminal or
loosen individual connections. Instead the complete sub−base
is removed, the electronic module replaced and the sub−base
placed into position again (see manual for the CPX I/O mod
ules).
