• inputs remain in their last, non-faulted state
Configure critical I/O modules to generate a controller major fault when they

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

based on old data from that module. To avoid potential
personal injury and damage to machinery, make sure this
does not create unsafe operation.
