(a) Operation chart of the G(P).RISEND instruction
Master station
CPU module
Command
G(P).RISEND
Device
1.
Writing of data to the buffer memory specified by (S1) + 2 and (S1) + 3 of the station specified by
(S1) + 1 is commanded.
2.
The data to be written to the target station is stored in the send buffer of the master station.
3.
Data are written to the buffer memory specified by (S1) + 2 and (S1) + 3 of the station specified by
(S1) + 1.
4.
The master station turns on the remote output (RY) specified by (S3) + 0.
5.
The station specified by (S1) + 1 performs the process for the remote output (RY).
6.
Upon completion of the process for the remote output (RY), the station specified by (S1) + 1 turns
on the remote input (RX) specified by (S3) + 1, and the remote output (RY) specified by (S3) + 0 is
turned off.
Also, the response indicating write completion to the master station is returned.
7.
The device specified by (D) turns on.
(b) Simultaneous execution of the G(P).RISEND instruction
The G(P).RISEND instruction can be simultaneously executed to multiple intelligent device stations.
But concurrent execution of the instruction is not allowed to the same station. (including other dedicated
instructions)
If the dedicated instruction is executed before the completion of the former dedicated instruction, the latter
instruction is ignored. Because several scans are required to complete the process of the dedicated instruction,
create a program so that the next dedicated instruction is executed after Completion device (D) turns on.
