Group Transient Transmission - Mitsubishi Electric MELSEC iQ-R Series User Manual

Group transient transmission

This function This function sends data to all stations of the same transient transmission group number by dividing the transient
transmission target stations into groups.
One network can be divided into a maximum of 32 groups.
Setting the group specification for the target station number of the control data of the link dedicated instruction allows
capturing of transient data at the station where the group number matches.
Executing instructions by setting No.1 for group specification from station No.2 allows capturing of transient data at three
stations: station No.3, station No.4, and station No.5.

Group No.1
(1) Control station (station No.1)
(2) Normal station (station No.2)
(3) Normal station (station No.3)
(4) Normal station (station No.4)
(5) Normal station (station No.5)
(6) Normal station (station No.6)

Precautions
• The execution cannot be checked with the transient transmission by group specification.
• If executed transient transmission continuously, transient transmission cannot be performed because of too much
processing of transient transmission (link dedicated instruction). Continuous execution may cause an error (Error code:
1845H). Therefore, perform debugging after ensuring that the execution interval is set in the system and check that
continuous execution can be performed.
