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.

This setting is enabled only when Destination network address specified" is set in word C. When specifying the destination network address, set all the nodes in the routing tables. For details on the routing tables, refer to Section 7 Network Interconnections.

Note 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-
