IEC Operators and additional norm extending functions

468 DMS 3.2 EN 02/2011 TD29 

PLC Designer IEC operator: Bitwise XOR of bit operands. The operands should be of the

type BOOL, BYTE, WORD or DWORD.

Regard the behaviour of the XOR function in extended form, that means if there are

more than 2 inputs. The inputs will be checked in pairs and the particular results

will then be compared again in pairs (this complies with the standard, but may not

be expected by the user).

Example in IL:

LD 2#1001_0011

XOR 2#1000_1010

ST Var1 (* Result is 2#0001_1001 *)

Example in ST:

Var1 := 2#1001_0011 XOR 2#1000_1010

Example in FBD:

PLC Designer IEC operator: Bitwise NOT of a bit operand. The operand should be of the

type BOOL, BYTE, WORD or DWORD.

Example in IL:

LD 2#1001_0011

ST Var1 (* Result is 2#0110_1100 *)
