The same data can be broadcast to all nodes
on the network by setting the destination node address to
FF (Hex).
The range of node addresses will vary for networks
other than Controller Link Networks.

I/O memory data from other nodes can be read or written by simply using the
program in the CPU Unit of a C200HX/HG/HE, CS/CJ-series, CVM1, CV-
series, or CQM1H-series PLC to execute SEND and RECV.
SEND transmits “n” words beginning with S (the beginning word for data
transmission at the source node) to “n” words beginning with D (the beginning
word for data reception at the destination node, N.)
