(13) Setting a link dedicated instruction and checking the processing
result
With link special relays (SB) and link special registers (SW), link dedicated
instructions can be set and the processing results can be checked.
1) Link dedicated instructions can be set with the following link special
registers (SW).
• Logical channel setting (SW0008 to SW000F)
• Number of retries (SW001C)
• Retry interval (SW001D)
• Number of gates (SW001E)
2) When data are stored in the host's channel area, the corresponding
RECV execution request flag (SB00A0 to SB00A7) turns ON.
Upon completion of the RECV instruction, the RECV instruction
execution request flag (SB00A0 to SB00A7) turns OFF.
3) Processing results of link dedicated instructions can be checked with
Send/receive instruction processing results (SW0031 to SW003F).
