Specialty Modules

In addition to the data bytes, the control/status byte is also displayed for select
modules. This byte is used for the bi-directional data exchange of the I/O module
with the higher-level control system.
The control byte controls the module's behavior and operation. The status byte
reports the module's status. It is possible to set the counter with the control byte or
indicate a range overflow/underflow with the status byte.
The special configuration of the respective control/status byte can be found
