Sample program
If CIO 0.00 (start bit) and A202.08 (CJ2 Instructions Enabled Flag) are ON, W10.00 (executing) will turn
ON.
When W10.00 (Executing) turns ON, the ten words of data starting from D100 (D100 to D109) are
received from the CPU Unit with node number 3 in the same network and written to ten words starting
from D200 (D200 to D209) at the local node. If a response is not received within 10 seconds, the data
will be resent up to 3 times.
If communications end normally, CIO 2.00 (execution completed) turns ON, and normal processing is
executed. If communications end in an error, CIO 2.01 (error end) turns ON, and error processing is
executed.
