 Arrange order: the order of the function component might result in
different outcomes of IF-THEN- ELSE rule execution, therefore, user could
click on
appropriate order.
The IF-THEN-ELSE logic engine operates according to following rules:

All rules are checked and the actions are executed by the top-down order.
 When the evaluation result of the IF statement is "true", the action with
"One-Time" operation mode would be executed only once; the action with
"Repeat" operation mode would be loop executed.

Only the actions of output channel setting of ICP DAS Module and Modbus
Module could be set to the "Repeat" operation mode. To execute the other
actions repeatedly, you can use the Timer function to perform it.
 If you want the action to be triggered "One-Time" again, the evaluation result of
the IF statement should return to "false" first, and then the action will be
executed when the evaluation result of the IF statement become "true" again.
The following section will give more detailed information of IF Condition and
