6.4.5 Station number overlap check function
This function checks the status of actually connected stations when the write request for data link start is
given (when BFM#10 b6 is set to ON), and checks whether the assigned station numbers overlap.
1. Number of occupied station number overlap checking
Checks whether or not occupied station numbers duplicate.
1) When there is an overlap, the ERR. LED flashes and the overlap status is stored in SW0098 (station
number overlap status).
2) Even if an overlap exists, data link can be continued with other normally functioning stations.
3) When the switch setting is corrected to normal status and the write request for data link startup is given
again (BFM#10 b6 is set to ON), the ERR. LED turns off and the data stored in SW0098 (station number
overlap status) is cleared.
However, if the starting head number overlaps, it is not regarded as an overlap check target.
Reads the status of SB0040
to SB004F.
