A compact module consists of a selection of individual modules accommodated together in a
single housing. From the software viewpoint, a compact module is handled in the same way as
the equivalent individual module structure, and is displayed in the same way in the SIMATIC
Manager engineering tool.
A distinction is made between “real” module types (also available as single modules) and “vir-
tual” module types (implemented only in the software).
The basic P-bus address is set on the compact module by means of an address coding plug.
The address offsets for the individual modules are accounted for automatically (see the table
below). The user simply has to ensure that the offset address range is not used by other mod-
ules. The address coding on the other modules must be lower than the basic address and
higher than the basic address +5 (or +7).
Compact modules are mapped to the SIMATIC memory in the order of their individual modules.
