32.12.3.5 Confirming Execution Results - XOR/XORP

Program Example

XOR

  1. When the positive transition instruction turns ON, the XOR instruction will be executed. When the XOR instruction is executed, the result value obtained by XORing Data_A with FOFF is stored in D1.
    When using a normally open instruction, as long as the instruction variable is ON, the XOR instruction is always executed.

XORP

  1. When the normally open instruction turns ON, the XORP instruction will be executed. When the XORP instruction is executed, the result value obtained by XORing Data_A with FOFF is stored in D1.
    Even when using a normally open instruction, the XORP instruction executes only when it detects the upward transition.
    Even if the normally open instruction variable remains ON,, the XORP instruction is executed only for one scan.
