Introduction
Section 6-1
2.
With the message service, there is no guarantee that a message to a re-
mote node will reach its destination. It is always possible that the message
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 occurring by
performing resend processing at the node where instructions are issued.
With the SEND, RECV, and CMND instructions, resend processing is per-
formed automatically once the number of retries has been set, so be sure
to specify a number other than “0” for the number of retries.
