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.

CMND sends “n” bytes of command data beginning with S (the beginning
word for storing command data at the source node) to node N. In return, “m”
bytes of response data are stored at the source node beginning with D (the
beginning word for storing response data).
1. When using CVM1 and CV-series PLCs manufactured prior to April 1996,
curring by performing resend processing at the node where instructions
are issued. With the SEND, RECV, and CMND instructions, resend pro-
cessing is performed automatically once the number of retries has been
set, so be sure to specify a number other than “0” for the number of retries.

the local network address cannot be set to “00.” Set a number other than
“00” as the local network address in the routing tables, and then specify
that number.
