10.2.1.1.4.3 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" configuration section, "Trigger" tab
1
Execute recording immediately
2
Initiate transmission
3
The alternative record interval should be used.
4
The alternative transmission cycle should be used.
5
Selection of whether the corresponding action should be completed when the value exceeds or drops
below the value in the "Threshold" field
Greater or
equal
Event trigger (RI, XM): The trigger is initiated, if the measurement value meets or
exceeds this value.
Level trigger (RA, QX): The trigger is active as long as the measurement value is higher
than the level or equal to the level.
Less or equal
Event trigger (RI, XM): The trigger is initiated, if the measurement value drops to or
below this value.
Level trigger (RA, QX): The trigger is active as long as the measurement value is lower
than the level or equal to the level.
6
Levels for initiating the trigger. The hysteresis is used to determine the level to reset the trigger.
7
Hysteresis for revoking the trigger (e.g. hyst=5%, level = greater or equal, trigger at 100 -> reset at 95)
Note:
The same hysteresis is used for all of the triggers.
