Note:
The addresses can be entered in German
and English notation (example:
E1.1
or
I1.1
).

Enters a comment for the absolute address
INPUT
Add
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.
ACTION
"PLC Trigger" tab
The comparison operation can be edited under "PLC Trigger".
Field Content

PLC trigger
Shows the comparison operations for the
AND logic operations in the trigger, which
can also be edited
TAB

INPUT
Trigger 1
Trigger 2
...
Trigger n
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.
