RECV receives "m" words beginning with S (the beginning word for data
transmission at the destination node, M) to the words from D (the beginning
word for data reception at the source node) onwards.

Local network
1. When communicating in the same network with a CVM1 or CV-series PLC
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-
