Specify the station No. of the target station.
1) Station No. specification
1 to 64 : Station No.
(To increase the reliability of data, it is recommended to execute the
instruction with the execution type in (S1)+0 set to "1: With arrival
confirmation".)
2) Group specification
81 to A0 : All stations in group No.1 to 32
H H
(Setting is available when the execution type is set to "0: With arrival
confirmation" in (S1)+0.)
3) All stations specification
FF : All stations of the target network No. (Except the host station)
H
(Setting is available when the execution type is set to "0: No arrival
confirmation" in (S1)+0.)
When a group is specified, set the group No. of the target station with the network
parameters from GX Developer.
1) For instruction execution
Specify the number of times the instruction is to be resent when it is not completed within
the monitoring time specified in (S1)+8.
(Setting is valid when the execution type is set to "1: With arrival confirmation" in (S1)+0.)
2) At instruction completion
The number of resends executed (result) is stored.
(Setting is valid when the execution type is set to "1: With arrival confirmation" in (S1)+0.)
Specify the monitoring time required for instruction completion.
(Setting is available when the execution type is set to "1: With arrival confirmation" in
(S1)+0.)
If an instruction is not completed within this time, it will be resent the number of times
specified in (S1)+7.
0 : 10 seconds
1 to 32767 : 1 to 32767 seconds
Specify the send data size of (S2) to (S2)+n. (Refer to Section 2.2.1.)
1 to 960: Number of send data (words)
The valid or invalid status of the data in the area starting from (S1)+12 is stored.
(Data are stored when "1: Clock data at the time of error completion is set in the area
starting from (S1)+11." is set in the error completion type in (S1)+0).
Note that the stored value will not be cleared even after the dedicated instruction is
completed.
