Operand Specifications
Description SWAP(637) switches the position of the two bytes in all of the words in the
range of memory from R1 to R1+N–1. This instruction can be used to reverse
the order of ASCII-code characters in each word.
Note SWAP(637) can be processed in the background. Refer to the SYSMAC CS/
CJ/NSJ Series PLC Programming Manual (W394) for details.
