Using Data Handling Instructions

9–15

Move (MOV)

This output instruction moves the source data to the destination location. As long as
the rung remains true, the instruction moves the data each scan.

Entering Parameters

Enter the following parameters when programming this instruction:

Source is the address or constant of the data you want to move.

Destination is the address where the instruction moves the data.

If you wish to move one word of data without affecting the math flags, use a copy
(COP) instruction with a length of 1 word instead of the MOV instruction.
