Enters a comment for the absolute
address
Adds the edited address to the AND logic
operation of the trigger conditions.
Notice:
The comparison operation must be
entered separately. ePS Network Services
permits saving without a comparison
operation; this renders the trigger
ineffective.
Content
Shows the comparison operations for the
AND logic operations in the trigger, which
can also be edited
The comparison operations for Trigger 1
and Trigger 2 are logic OR.
The comparison operation consists of the
comparison operation (>, <, =, <>) and the
fixed comparison value (digit).
Notice:
ePS Network Services will not check the
plausibility of the variable address for the
potential comparison operation and actual
comparison value.
It is possible but not meaningful to compare
a binary address M1.1 with greater than
9999.
Entry for a comparison value tolerance, in
which the trigger condition is still fulfilled.
Note:
ePS Network Services will not check the
specified tolerance for plausibility. The
tolerance is only advisable in = operations
with values (no binary signals).
With >, < operations, the comparison value
can be specified correctly instead of the
tolerance, as a tolerance direction has no
effect.
