1.7.2.2.6 I/O Configuration
The CI592-CS31 module does not store configuration data itself. The configurable channels are
defined as inputs or outputs by the user program, i.e. each of the configurable channels can be
used as input or output (or re-readable output) by interrogation or allocation by the user pro-
gram.
1.7.2.2.7 Addressing
An address must be set at every module so that the field bus communication module can
access the specific inputs and outputs.
A detailed description concerning "addressing" can be found in the chapters "Addressing" of the
CPUs and Communication Modules.
The address (00d to 99d) is set with two rotary switches on the front panel of the module.
The CS31 Bus Module reads the position of the address switches only during
the initialization after power ON, i.e. changes of the setting during operation
remain ineffective.
