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).
