Write Data to One Channel
The following example can be used if only one channel is to be written to, or if the outputs
are to be controlled individually.

V40501
TheLD instruction loadsthe data intothe
accumulator.Since SP1 is used, this rung
automatically executes on every scan.
Permissive contacts X, C, etc. could also be used.
TheBIN instruction converts theaccumulator data
to binary (omitthis step aif is already in binary format).
TheOUT instruction writes thedatatothe module output.
This example starts with V40501, but theactual value
dependsonthe location of themodule in your application.
