Table 29: Error Detection - WAGO 750 Manual

64 Commissioning
Using the cyclical tests of the digital inputs, the F I/O module detects the
following errors at the digital inputs:

Behavior of the F I/O module in the event of an error
If an overload is detected by the F I/O module at a clock output, then the clock
output is switched off, and the associated inputs are passivated by setting the
process image of the inputs to the value "0." For all other errors, only the relevant
input is passivated.
You can find detailed information in section "Diagnostics."
