WAGO-I/O-SYSTEM 750  System Description

2.1.2.7 Process Image

Some fieldbus systems can process input channel status information by means
of a status byte.
This status byte can be displayed via the WAGO-I/O-CHECK 2 start-up and
diagnostic tool. However, processing via the coupler / controller is optional,
which means that accessing or parsing the status information depends on the
fieldbus system.
Attention
The representation of the process data of some I/O modules or their variations
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
corresponding coupler/controller.
