Depending on the link refresh timing, the update of 'Baton pass
status of each station' (SW00A0 to SW00A7) may be offset by one
sequence scan.
(Conditions)
• This relay is enabled when 'Baton pass status of own station'
(SB0047) is off.
• When 'Baton pass status of own station' (SB0047) is turned on,
data prior to error is held.
