observe the feedback output for the digital output
while forcing the value ON and OFF. If shorted
high, the feedback will remain ON regardless of
the forced value.
3. Remove any wires from the digital output at the
IO module connection and see if the feedback
begins to operate following the commanded
value. If the output operates correctly without
anything connected to the module, the problem is
most likely with the wiring outside the controller. If
the problem persists after removing the wires
from the connector, the problem is most likely
inside the IO module.
