Precautions Section 1-2
Example: The following example will move #200 to D200 if D100 contains
#10 and move #300 to D300 if D100 does not contain #10.
The Equals Flag will turn ON if D100 in the rung above contains #10. #200 will
be moved to D200 for instruction (1), but then the Equals Flag will be turned
OFF because the #200 source data is not 0000 hex. The MOV instruction at
(2) will then be executed and #300 will be moved to D300. A rung will there-
fore have to be inserted as shown below to prevent execution results for the
first MOVE instruction from being picked up.
