PLC Network Instructions Section 6-2
6. Port Number
Set the communications port number that the RECV(98) instruction will be
sent to.
7. Number of Retries
Set the number of retries for unsuccessful transmissions. You can set the
number between 1 to 15. If 15 has been set, for example, the RECV(98)
instructions will be re-transmitted up to 15 times when the PLC does not
receive a response from the destination node.
8. Response Monitor Time
Designates the length of time that the PLC retries transmission when bit
15 of C+3 is OFF and no response is received. The default value is $0000,
which indicates 2 seconds.
