15 NETWORK COMMON INSTRUCTIONS
15.1 Link Dedicated Instructions
• The continuous area (a maximum of 960 words) for the receive data length ((s)+9) is required in the receive
data storage device (d1).
• The RECV instruction is executed each time the bit of the relevant channel in the RECV instruction request
area (address 205) in the buffer memory is set to ON (received data exists).
• When multiple network modules with the same network number are mounted in the own station, Specify "U"
(start I/O number) to execute the RECV instruction. The RECV instruction cannot be executed by specifying
"J" (network number).
(Example: When executing the GP.RECV instruction in station number 3 with regard to the SEND instruction
from station number 2, specify "U2".)
