Monitor Status and Handle Faults
The GuardLogix® architecture provides you with many ways of detecting and
reacting to faults in the system. The first way that you can handle faults is to make
sure you have completed the checklists for your application (see
Appendix D).
Monitoring System Status
You can view the status of safety tag connections. You can also determine current
operating status by interrogating various device objects. It is your responsibility to
determine what data is most appropriate to initiate a shutdown sequence.
CONNECTION_STATUS Data
The first member of the tag structure associated with safety input data and
produced/consumed safety tag data contains the status of the connection. This
member is a pre-defined data type called CONNECTION_STATUS.
