With the RECV(098) instruction, the data in m number of words, starting from
the beginning word S at the remote node (node address M) is received at the
words starting from the beginning word D at the local node.
The message services function does not guarantee that a message will reach
the destination node. A message may be lost during transmission due to fac-
tors such as noise. In order to prevent this from occurring when using mes-
sage services, it is common to set up retry processing at the node from which
instructions are issued. With the SEND(090), RECV(098), and CMND(490)
instructions, retry processing is executed automatically by specifying the num-
ber of retries, so specify a number other than 0.
