9. DEDICATED INSTRUCTIONS AND PROGRAMMING
(b) The G(P).RISEND 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).RISEND instruction: the
completion device (D) and the status display device at completion (D)+1.
1) Completion device
Turns ON in the END processing of the scan where the G(P).RISEND
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).RISEND instruction.
Normal completion : Stays OFF and does not change.
Abnormal completion: Turns ON in the END processing of the scan
where the G(P).RISEND 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).RISEND instruction is 10 steps.
(f) The send 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.
