Description
Stores the maximum value of the link scan time during cyclic transmission. (Unit: ms)
When the constant link scan is specified, the register is set as follows:
■For the control station
• When the setting value is smaller than "Link scan actual measurement value + KB in
the link scan time calculation formula", the value of "Link scan actual measurement
value + KB in the link scan time calculation formula" is stored.
• When the setting value is larger than "Link scan actual measurement value + KB in the
link scan time calculation formula", the link scan actual measurement value is stored.
■For the normal station
• The set constant link scan value is stored.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
Stores the minimum value of the link scan time during cyclic transmission. (Unit: ms)
When the constant link scan is specified, the register is set as follows:
