Specialty Modules

In addition to the data bytes, the control/status byte is also displayed for select
I/O 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 I/O module's behavior and operation. The status
byte reports the I/O 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 control/status byte is always in the low byte in the process image.
Information for the control/status byte development
Please refer to the corresponding description of the I/O modules for the structure
of the control/status bytes. You can find a manual with the relevant I/O module
description at: http://www.wago.com.

Serial Interfaces with Alternative Data Format

The process image depends on the parameterized operating mode!
The operating mode of the configurable I/O module can be set. Based on the
operating mode, the process image of these I/O modules is then the same as
that of the respective version.
The I/O modules with serial interface that are set to the alternative data format
occupy 4 bytes of user data in the input and output area of the process image, 3
data bytes and one additional control/status byte. Two words are assigned in the
process image via word alignment.
