controller in order to give an indication on the expected
event.
2. The operated setpoint status is latched to the setpoint
alarm latch register accessible through communications.
The register holds the last setpoint alarm status until it is
explicitly cleared through communications.
3. Up to four programmable actions can be performed in
sequence on setpoint status transition when a setpoint
event is asserted.
Generally, setpoint actions are performed independently for each setpoint
and can be repeated a number of times for the same target. The exceptions
are relay operations, data logging and waveform logging that are shared for
each separate target between all setpoints using an OR scheme.
A relay output is operated when one of the setpoints linked to the relay is
activated and will stay in the operated state until all of these setpoints are
released (except for latched relays that require a separate release command
to be deactivated).
Data logging and waveform logging directed to the same file are done once
for the first setpoint among those that specify the same action, guaranteeing
that there will not be repeated records related to the same time.
Recording Setpoint Events
Time-tagged setpoint events can be recorded to the device Event Log if you
put a corresponding action into the setpoint action list. The Event Recorder
will log any setpoint transition event: both when the setpoint is operated, and
when it is released. The Event Recorder will put into a log file a separate
record for each active trigger caused a setpoint status transition, and a
separate record for each action done on the setpoint activation (except for
data logging actions that are not recorded to the Event Log).
