same target. The exceptions are relay operations, data
logging and waveform logging that are shared between all
setpoints using an OR scheme for each separate target.
A relay output is operated when one of the setpoints linked to
the relay is activated and stays 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 Event log
if you put the corresponding action to the setpoint action list.
If you select to record setpoint operations into the Event log,
define in the action target box which transition events you
want to be recorded: when the setpoint is operated, when it
is released, or both events. The Event recorder puts 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 logging
actions that are not recorded to the Event log).
If you run a number of recorders from the same setpoint
action list, it is recommended that you put the Event log
action before others in order to allow other recorders to use
the event sequence number given to the event by the Event
recorder.
