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.
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.

"m" number of send words
0000 to 03DE (Hex): 0 to 990 words
0: Source network address not specified (local network)
1: Source network address specified.

Destination network address
00 (Hex): Local network
01 to 7F (Hex): 1 to 127
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
1. When communicating in the same network with CVM1 and CV-series PCs
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.
