9.2.2.3 Trigger
There are two types of triggers:
l
Event trigger (RI, XM)
The relevant operation (e.g. initiate transmission) is only executed once when the trigger event occurs.
l
Level trigger (RA, QX)
The relevant operation (e.g. use alternative record interval) is executed as long as the trigger is active.
"Measurement channels – Trigger" configuration section
1 Freely selectable channel title for the input
2 The alternative record interval should be used.
3 Initiate transmission
4 Activate online mode
5 The alternative transmission cycle should be used.
6 Selection of what the relationship between the measurement value and level must be to initiate the
trigger.
Greater
or
equal The trigger is active as long as the measurement value is higher than the level or equal to the
level.
Less or
equal The trigger is active as long as the measurement value is lower than the level or equal to the
level.
7 Levels for initiating the trigger. The hysteresis from the "Alarm" tab is used to determine the level to reset
the trigger.
8 Hysteresis for revoking the trigger (e.g. hyst=5%, level = greater or equal, trigger at 100 -> reset at 95)
