An interrupt program can be started when the SEND instruction is received at the
channel whose parameters are designated with the RECVS instruction.
When "RECV instruction" is selected as the device code, the settings of "Channel No."
and "Interrupt (SI) No." are enabled.
In the example below, data is sent from station number 3 to channel 5 of station
number 15 using the SEND instruction.
The interrupt program setting parameters of station number 15 are set so that the
interrupt program is started by the SEND instruction to channel 5.
