Programming Appendix A
Example: The following example will move #0200 to D00200 if D00100 contains #0010 and move #0300
to D00300 if D00100 does not contain #0010.
The Equals Flag will turn ON if D00100 in the rung above contains #0010. #0200 will be moved to D00200
for instruction (1), but then the Equals Flag will be turned OFF because the #0200 source data is not 0000
hex. The MOV instruction at (2) will then be executed and #0300 will be moved to D00300. A rung will
therefore have to be inserted as shown below to prevent execution results for the first MOVE instruction
from being picked up.
