When specifying a destination network address, set all the nodes in the routing tables. For de
tails on routing tables, refer to
Note
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.)

Section 7 Network Interconnections.
1. When communicating in the same network with CVM1 and CV-series
PLCs manufactured prior to April 1996, 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.
2. With the message service, there is no guarantee that a message to a des-
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 executed. 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.

Response monitor time
00 (Hex): 2 s (for 2 Mbps)

01 to FE (Hex): 0.1 to 25.4 s (unit: 0.1 s)
FF (Hex): No response monitoring
Destination node address (N)
01 to 20 (Hex): 1 to 32 (or 01 to 3E (Hex): 1 to 62)
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.
