Message: Compare not possible on objects of type '<data type>'

Possible error cause: Objects are being compared in which a comparison is not possible.

Error correction: Compare only data types in which a comparison is possible (INT, REAL, etc.).

Example of the error:

PROGRAM PLC_PRG
VAR
	b : BOOL;
	arr1 : ARRAY [1..2] OF INT;
	arr2 : ARRAY [1..2] OF INT;
END_VAR

b := arr1 > arr2;


--> C0068: Compare not possible on objects of type 'ARRAY [1..2]'
