Operator: XOR
The 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
Important
Note the following behavior of the XOR POU in extended form (more than two inputs): compares the inputs in pairs and then the corresponding results (according to the standard, but not necessarily according to expectations).
Example 116. Examples
Result in var1: 2#0001_1001
ST
var1 := 2#1001_0011 XOR 2#1000_1010;
