9. DEDICATED INSTRUCTIONS AND PROGRAMMING
(b) The G(P).RIRCV instruction can be executed to multiple intelligent device
stations simultaneously.
Note that concurrent execution of multiple instructions including other
dedicated instruction(s) (refer to Section 9.1) is not allowed to the same local
station or intelligent device station.
Create a program in which a flag remains on until the instruction is
completed.
(c) There are two types of interlock signals for the G(P).RIRCV instruction: the
completion device (D2) and the status display device at completion (D2)+1.
1) Completion device
Turns ON in the END processing of the scan where the G(P).RIRCV
instruction is completed, and turns OFF in the next END processing.
2) Status display device at completion
Turns ON and OFF depending on the completion status of the
G(P).RIRCV instruction.
Normal completion: Stays OFF and does not change.
Abnormal completion: Turns ON in the END processing of the scan
where the G(P).RIRCV instruction is completed, and turns OFF in the
next END processing.

(d) Multiple dedicated instructions cannot be executed for the same station.
Since it takes several scans until the processing of the dedicated instruction
is completed, execute the next dedicated instruction after the completion
device has turned ON.
The next dedicated instruction executed before completion of the previously
executed dedicated instruction is ignored.
(e) The basic number of steps of the G(P).RIRCV instruction is 10 steps.
(f) The receive buffer assignment is performed in "Station Information Setting"
of Network Parameter of GX Works2. For more details on setting, refer to
Sections 7.2.2, 7.3.2 and 7.4.2.
