7.2.1 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
*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.
*1 Indicates base units on which the CC-Link IE Controller Network module is mounted.
L: Interlink transmission time
LB: Total number of actual link refresh points in LB
