Write Data to One Channel
If only one channel is being used, or if the updates are to be controlled separately, the following
program can be used.
Write the same Data to Both Channels
If both channel select outputs are off, then both channels will be updated with the same data.

BIN

LD
V2000
OUT
V40501
The LD instruction loads the data into the
accumulator. Since SP1 is used, this rung
automatically executes on every scan. X, C, etc.
can also be used as permissive contacts.
The BIN instruction converts the accumulator data
to binary (you must omit this step if you have
already converted the data elsewhere).
The OUT instruction sends the data to the module. Our
example starts with V40501, but the actual value
depends on the location of the module in your
application.
RST
Y40
OUT
Y41
Y40--OFF selects channel 1 for updating.
Y41--ON deselects channel 2 (do not update).
Note: Use LD if using binary, and use LDD if using BCD.
