Module identifiers Each module, including the bus node, has its own identifier,
the so-called module identifier. It serves to determine and
localise the module type, for example as part of configura-
tion. Apply the module identifiers – from left to right, corres-
ponding to the physical order as installed in the CPX termin-
al – in yo ur configuration program (e.g. Siemens SIMATIC
STEP 7, see sectio n 2.7).
In graphically oriented configuration programs, the module
identifiers are typically found in a separate listing of all avail-
able hardware modules or field devices, e.g. in a module
folder or module catalogue.
Electric modules
Tab. 2/1 shows the assigned address space of the bus node
in the Remote Contro l l er operating mode.
Tab. 2/2 to Tab. 2/4 gi ve an overview of the assigned address
spaces of different electri c modules and of the bus node in
the remote I/O operati ng mode.
The address assignment within the individual CPX modules
can be found in the associated descriptions, e.g. P.BE- CPX-
EA-... and P.BE-CPX-AX-...
Details on the CP interface can be found in the description for
the CP interface (P.BE-CPX-CP-...).
Configuration
of the bus node
In the Remote Controller (RC) operating mo de, only the
identifier of the bus node will be configured (see Tab. 2/1).
In the Remote I/O (RIO ) operating mode, the identifiers of
the bus node (including diagnostics mode), the CPX mod-
ules and, if present, the pneumatics modules are configured
(see Tab. 2/2).
