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.
