WAGO-I/O-SYSTEM 750
I/O Modules
Some fieldbus systems can process input channel status information by means
of a status byte.
This status byte can be displayed using the starting tool WAGO-I/O-CHECK
2. However, the coupler / controller process operation 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 fieldbus 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 re-
spective control/status bytes from the section "Fieldbus specific design of the
process data" included in the description of the process image of the corre-
sponding coupler/controller.
