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 issued. 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.
cle time will be increased. This may cause timeout errors to occur when
waiting for the response. In that case, lengthen the response monitor time

to “00.” Set a number other than “00” as the local network address in the
routing tables, and then specify that number.
