description
Function
(switching condition)
MAX (x>limit)
The event trigger will switch if the measured value exceeds the upper
limit.
MIN (x<limit)
The event trigger will switch if the measured value falls below the
lower limit.
ERR (x=fail)
The event trigger will switch if a measurement is not possible.
Within range
The event trigger will switch if the measured value is within the
defined range.
Out of range
The event trigger will switch if the measured value is outside the
defined range.
Type
(holding behavior)
Non-hold
If the switching condition is no longer met, the event trigger will return
to the idle state after approx. 1 s.
Hold
The event trigger remains activated even if the switching condition is
no longer met.
Hold for a while
The event trigger remains activated during a defined time even if the
switching condition is no longer met.
