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.
