Section 8.4.2 Network range assignment screen
It is used to set the constant link scan time, block data assurance per station, punctuality
assurance, and maximum number of transients in one station.
*1: If a longer constant link scan time is set, an error may be detected on 'baton pass status of each
station' (SW00A0 to SW00A7) and 'cyclic transmission status of each station' (SW00B0 to
SW00B7) of all stations for approximately 300ms + 1 link scan time when the personal computer
or board is reset.
*2: The separation prevention refers to a prevention of link data with double words (32 bits), such as
the current value of the positioning module, from being separated to new data and old data in units
of one word (16 bits) due to the refresh timing of cyclic transmission.
*3: The following table indicates the link scan operation with or without punctuality assurance.

Punctuality assurance
Link scan operation
With assurance
• Constant link scan time is maintained.
• Link scan time is longer than the setting without assurance.
• Link scan time becomes longer as the larger number is set for "Maximum No. of transients in one station".
Without assurance
• A variation in link scan time occurs when a transient transmission is requested.
• A variation in link scan time becomes larger as the larger number is set for "Maximum No. of transients in
one station".
