Cooperative Operation of the ControlNet Ex Adapter and FLEX Ex
Output Modules

The ControlNet Ex adapter (1797-ACNR15) combined with FLEX Ex
output module provides a two-tier fault state mechanism. It is important to
consider and understand the operation of this mechanism when designing
your system.
Two sets of programmable fault states are available, one each in the adapter
and output module. This two-tier method is meant to give you a wider fault
coverage compared with normal methods.
