V40501
TheLD instruction loadsthe data intothe
accumulator. Since SP1 is used, this rung
automatically executes on every scan. X, C, etc.
can also be used as permissive contacts.
TheBIN instruction converts theaccumulator data
to binary (you must omit this step if youhave
already convertedthe data elsewhere).
TheOUT instruction sends the datatothe module.Our

Y40--OFF selects channel 1for updating.
Y41--ON deselects channel 2(do not update).
Note:Use LD if usingbinary, and useLDD if usingBCD.
