The following program example shows how to send digital values to the module
when you have more than one channel. This example assumes you have already
loaded the data according to the following table. It is important to use the rungs in
the order shown for the program to work. This example will not work with D4–430
CPUs.

When channel 8 is updated, C0 restarts the update
OUT
sequence.
When channel 7 has been updated, this rung loads
LD
the data for channel 8 into the accumulator.
V3007
C10
Turning on C10 triggers the channel update (see
OUT
the channel select rungs).
When channel 6 has been updated, this rung loads
LD
the data for channel 7 into the accumulator.
V3006
C7
Turning on C7 triggers the channel update (see the
OUT
channel select rungs).
When channel 5 has been updated, this rung loads
LD
the data for channel 6 into the accumulator.
V3005
C6
Turning on C6 triggers the channel update (see the
OUT
channel select rungs).
When channel 4 has been updated, this rung loads
LD
the data for channel 5 into the accumulator.
V3004
C5
Turning on C5 triggers the channel update (see the
OUT
channel select rungs).
