Rockwell Automation Sequencer Object (P_Seq)
If branching is configured for a step there are four options:
• Continuous - Always take a branch
• Loop count - Take a branch until the step has been executed a given
number of times
• Input pattern - Take a branch if a specific input pattern exists within the
Boolean inputs
• Manual prompt - Configure the manual prompt to prompt you for a
branching decision
See page 31 for more information.
Alarm Options
There are three optional alarms that can be configured to instruct the Sequencer
to take a particular action if an alarm occurs. The Alarm Summary tab shows one
of these records.
• Interlock Trip - Alerts you that an interlock condition has been triggered.
• Sequence Timeout - Alerts you that a sequence has run longer
than expected.
• Step Timeout - Alerts you that a step has run longer than expected.
Engineering configuration options let you determine what action the Sequencer
is to take if an interlock trips, if the Step Fault Timer expires, or the Sequencer
Fault Timer expires.
