Interlink transmission time

The following are the calculation formulas for the interlink transmission time.
(1) For High Performance model QCPUs, Process CPUs, and Redundant CPUs
α =KM4+KM5×
L
L:
Interlink transmission time
LB: Total number of actual link refresh points in LB
LW: Total number of actual link refresh points in LW
KM4 and KM5:
*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.
