Description
You use the "Invert RLO" instruction to invert the signal state of the result of logic operation (RLO).
Example
The following example shows how the instruction works:
The "TagOut" output is set when the following conditions are fulfilled:
-
The input "TagIn_1" and/or "TagIn_2" has signal state "0".
-
The input "TagIn_3" and/or "TagIn_4" has signal state "0" or the input "TagIn_5" has signal state "1".
