Special identifier format and groupable identifiers
Configuration is made PROFIBUS−specific byte−by−byte.
By means of a special identifier format, you can group some
modules together within a byte. The data volume will then be
reduced.

You can only group together modules of the same type:
 input modules with input modules
 output modules with output modules
 pneumatic modules of type MPA2 with modules of type
MPA2
Between the grouped electric modules there may be any
other electric module types. Further information can be
found in the following configuration examples:
Note
Make sure that the modules are correctly grouped
together. The project planning software does not make a
check.
