8.1 I/O Module Behavior in the Event of an Error
The response of the I/O module if a diagnostic is present depends on the
configuration for wire break monitoring, underrange/overrange monitoring and
upper/lower limiting value monitoring. You can activate or deactivate these
diagnostics individually in WAGO-I/O-
CHECK
(see section
“Startup” > … > “Parameterization with WAGO-I/O- CHECK ” > … > menu item
“Channel settings”).
The I/O module only allows one error to be indicated. A dedicated bit in the status
byte is assigned to each error status. The associated status bit is set if an error
status is detected. Certain errors cause multiple error statuses to occur. This is
why error statuses are given priority levels. In the event of several errors being
present, the error with the highest priority will always be displayed.
The following priority levels apply:
