S5 Distributed Control
Systems
The Siemens S5 allows for remote I/O to be connected to a centralized CPU
with interface modules installed in the centralized rack and expansion racks.
The S5 series programmable controllers can comprise a central controller (CC)
and, depending on the configuration, one or more expansion units (EUs).
Expansion units are used when there are insufficient central controller slots, or
to locate I/O modules as closely as possible to the associated field devices.
To permit communication between the central controller and the expansion
unit, a central controller interface module is installed in the central controller
rack and an expansion unit interface module is installed in the expansion unit.
The type of interface module used is dependent on the type of expansion units
racks. The interface modules for the central controller rack and the expansion
rack come in pairs. For example, IM300 for the central controller rack
combined with the IM310 for expansion racks.
