* 1 Total number of link device points for the range set by refresh parameters and set in the network
range assignment. Note that the points assigned to reserved stations are excluded.
POINT
The values in this section are calculated on the basis that data are received from
all stations during one sequence scan.
When the link scan is long or when the sequence scan is short, data from all
stations may not be received within one sequence scan.
If this occurs, the actual link refresh time is less than the calculated value shown
in this section.
T: Link refresh time on sending side
R: Link refresh time on receiving side
LB: Total number of actual link refresh points in LB
