Operator ‘XOR’

This IEC operator is used for the bitwise XOR of bit operands.

When only one of the two input bits yields 1, the output bit also yields 1. When both inputs yield 1 or 0, then the output yields 0.

Permitted data types: BOOL, BYTE, WORD, DWORD, LWORD

Attention

Please note the following behavior of the XOR block in extended form (more than two inputs): CODESYS compares the inputs in pairs and then the corresponding results (according to the standard, but not necessarily according to expectations).

Examples

Result in var1: 2#0001_1001

ST:

var1 := 2#1001_0011 XOR 2#1000_1010;
