The I/O module provides 1 status byte (8 bits) and 1 data word (16 bits) per
channel.
The digitalized measured value is transmitted to the process image of the
fieldbus coupler/controller in a data word (16 bits) as an input byte 0 (low) and
input byte 1 (high). This value is mapped with a resolution of 12 bits on bit B3 ...
B14. Status information, which can be evaluated for fault detection, is contained
in the 3 least significant bits (B0 ... B2).
In the event of an overrange, bit B0 = 1 is set.

Evaluation of Status Byte
Some fieldbus systems can process status information of process value by
means of a status byte.
This status byte can be displayed via the commissioning tool WAGO-I/O-
CHECK.
However, processing via the fieldbus coupler/controller is optional, which means
that accessing or parsing the status information depends on the fieldbus system.

Mapping of process data in the process image of fieldbus systems
The representation of the I/O modules' process data in the process image
depends on the fieldbus coupler/controller used. Please take this information as
well as the particular design of the respective control/status bytes from the
section "Fieldbus Specific Design of the Process Data" included in the description
concerning the process image of the fieldbus coupler/controller used.
