SEND transmits “n” words beginning with S (the beginning word for data
transmission at the source node) to “n” words beginning with D (the beginning
word for data reception at the destination node, N.)

tination node will reach its destination. It is always possible that the mes-
sage 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 oc-
curring by performing resend processing at the node where instructions
are executed. With the SEND, RECV, and CMND instructions, resend pro-
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.
