Operator
B_OR
B_AND
B_XOR
B_NOT
Priority of the operators
The operators have the following priorities for execution in the synchronized action (highest
priority: 1):

10
11
Note
It is strongly recommended that the individual operators are clearly prioritized by setting
parentheses "( ... )" when several operators are used in an expression.
Example of a condition with an expression with several operators:
Program code
... WHEN ($AA_IM[X] > VALUE) AND ($AA_IM[Y] > VALUE1) DO ...
