Each number in the table represents a station number.
 is fixed to 0.
This flag is enabled when 'Baton pass status of own station' (RWr6.b0) is off (normal). When it is turned on (faulty), the data
prior to the error is retained. ( Page 180 Baton pass status of own station (RWr6.b0))
• If multiple stations change from faulty to normal, they are reconnected to the network one by one per link
scan, so the time until the status changes to off (data link normal station) may vary by several seconds.
• If no response is received for several link scans, the station is determined to be a data link faulty station.
• Reserved stations and stations higher than the maximum station number are ignored.
• Depending on the update timing, the timing to retain and clear remote I/O signals from I/O maintenance
settings may differ.
