Name of variable
p4: Safety input/output
processing time
kp
kum: Inter-module
synchronous processing
time (multicast)
*1 The switching hub delay time changes depending on the hub models and settings.
*2 Total number of points is the smallest value set in "Start" to the largest value set in "End" of "Network Configuration Settings".
*3 This is the slave station with the largest calculation value when, for each slave station (including extension modules), (("RX setting" +
"LB setting")/8) + (("RWr setting" + "LW setting")  2) is calculated.
*4 Calculate by rounding up each calculation result in brackets.
*5 In "Inter-module Synchronization Setting" under "System Parameter" of the master station, "Use Inter-module Synchronization Function
in System" is set to "Not Use" or "Select Inter-module Synchronization Target Module" is set to "Do Not Synchronize".

Description
7000  (The number of connections of "Safety Communication Setting" in "Basic Settings" set in the master station) + 20000
However, if the number of connections of "Safety Communication Setting" in "Basic Settings" set in the master station + 0, then
p4=0.
78000
2000  (Number of slave stations) +18000
However, if the inter-module synchronization is not performed in the master station
*5
, then kum=0.
