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.

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.)

tination node will reach its destination. It is always possible that the mes-
sage may be lost in transit due to noise or some other condition. When
using the message service, it is advisable to prevent this situation from oc-
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.

If the baud rate is slow, then setting a small
