    Hello,

    I want to compare some arrays but what I'm doing is not working.

    Here is my code: 

    VAR   
   i               : INT;   
   xValueChanged              : BOOL;
   xInitialStatusSensor      : ARRAY [0..5] OF BOOL := [TRUE, FALSE , TRUE, FALSE, FALSE];
   xRunTimeStatusSensor      : ARRAY [0..5] OF BOOL := [TRUE, FALSE , FAlSE, FALSE, FALSE];
END_VAR
FOR i:= 0 TO 5 DO
   
   IF xInitialStatusSensor[i] <> xRunTimeStatusSensor[i]  THEN
         
      xValueChanged := TRUE;
   ELSE
         
      xValueChanged := FALSE;
      
   END_IF
END_FOR

    Any idea?
    Thanks in advanced

    In the last cycle of your FOR loop the result is determined.
    Maybe better to use e.g.:

    xValueChanged := FALSE;
FOR i:= 0 TO 5 DO
   IF xInitialStatusSensor[i] <> xRunTimeStatusSensor[i]  THEN
      xValueChanged := TRUE;
     // EXIT optionally 
   END_IF
END_FOR
