Using Module Tags
Fault and Status Reporting
Between the Module
and Controllers
Sequence of Events modules multicast fault/status data to the
owner-controller. The module maintains a Module Fault Word, the
highest level of fault reporting.
Table D.1 describes the tag that can be examined in ladder logic to
indicate when a fault has occurred for your Sequence of Events
module:
Each bit corresponds to an individual input.
If a communication fault occurs on the Sequence of Events
module, all 32 bits in the Module Fault Word are set to 1.
If chatter is detected on any input points, the bit corresponding
to that point is set to 1.
