Dynamic Configuration

Dynamic configuration is the specification and configuration of a maximum
configuration. Any subgroup of this maximum configuration can be operated.
In addition to dynamic configuration, empty spaces in the I/O Station can be
reserved for future expansion.
Empty spaces that have been reserved can be used at different
configuration levels. Configuring the maximum configuration level reserves
memory in the PLC. The optional modules must not be connected. They can
be deactivated in the configuration.
If the I/O Station is subsequently expanded to include previously-
deactivated modules, the new modules can be connected and activated in
the hardware configuration.

Indexes

n dynamic configuration, a maximum I/O Station is specified during
I
configuration, reserving extra addresses in the PLC. Any subgroup of this
maximum configuration can be operated. The advantage is that several I/O
Stations with the same device number but different configurations can be
used in the field, although only one such station can ever be active on
Profibus.
Profibus NIU PBI002 uses three "indexes" for information about the modules
in the VersaPoint I/O Station.
