Exclusive OR NOT Connection
The content of the accumulator is connected with the inverted expression in the following brackets by a logical XOR operation. The result is transferred to the accumulator.
Valid operands for this operator must be of one of the following data types: (BOOL, WORD, DWORD)
LD |
var_1 |
(* Load var_1 in accu *) |
(* Since bracket expression follows, save content of accu; process expression in brackets first *) |
||
XORN( |
var_2 |
(* Load var_2 in accu *) |
OR |
var_3 |
(* Perform OR of var_3 with accu; store result in accu *) |
) |
(* Perform XOR of saved accu content with inverted actual content of accu; store result in accu *) |
|
ST |
var_4 |
(* Store accu in var_4 *) |
