• inputs remain in their last, non-faulted state

Most I/O modules have fault bits that indicate when a fault occurs at a specific

point of a module. To view this data through the programming software:

You can write logic to monitor these bits and take appropriate action if a fault

occurs. For example, you may want to shut down the system if a specific point

ATTENTION

If a module loses its connection to the controller, the

controller and other I/O modules continue to operate

based on old data from that module. To avoid potential

personal injury and damage to machinery, make sure this

does not create unsafe operation.
