Name of variable Description
ndm ((Total number of points of "RY setting") / 8) + ((Total number of points of "RWw setting")  2)
Sn Number of device stations
nh Switching hub delay time  Number of switching hubs connected to the network
Switching hub delay time: 50000
n3 Sn  nhs
nhs: Value of (nds + (20  n4)) / (1488  Sn) rounded up to the nearest integer
n4 Sn  (RXb + RWrb) + Sn
RXb: Value of (Total number of points of "RX setting") / (11744  Sn) rounded up to the nearest integer
RWrb: Value of (Total number of points of "RWr setting") / (734  Sn) rounded up to the nearest integer
nds ((Total number of points of "RX setting") / 8) + ((Total number of points of "RWr setting")  2) + 8  Sn
n5 Value of (ndl + 20  n6)/1488 rounded up to the nearest integer
n6 (ndl - 8) / 1468 + 1
ndl (RXl / 8) + (RWrl  2) + 8
RXl: Number of points of "RX setting" of the device station
RWrl: Number of points of "RWr setting" of the device station
E E: (Sn - 1)  830 + 39102
Round up values of E that are less than 1 s.
n7 When "CC-Link IE TSN Class Setting" is set to "Mixture of CC-Link IE TSN Class B/A or CC-Link IE TSN Class A Only", and "TSN
HUB Setting" is set to "Not to Use TSN HUB": 4
Other than the above: 0
p1: RX/RY/RWr/RWw {((Total number of points of "RX setting") + (Total number of points of "RY setting"))/8 + ((Total number of points of "RWr setting") +
processing time (Total number of points of "RWw setting"))  2}  5 + (Sn  3300)
However, if Total number of points of "RY setting" = Total number of points of "RX setting" = Total number of points of "RWr setting"
= Total number of points of "RWw setting" = 0, then p1 = 0.
p4: RX/RY/RWr/RWw (((dw  kX) + kY)  Mg) + kM
*3
data transfer time However, if dW is 0, p4 = 0.
dw: Total number of ((sRX + sRY) / 16) + sRWr + sRWw [Word]
words
sRX Total number of points of "RY setting"
sRY Total number of points of "RY setting"
sRWr Total number of points of "RWr setting"
sRWw Total number of points of "RWw setting"
kX dW is less than 1000 [words]: 580
dW is 1000 [words] or more: 254
kY dW is less than 1000 [words]: 160000
dW is 1000 [words] or more: 477200
Mg Station-based block data assurance setting
Assured: 1
Not assured: 1.55
kM Sn  10000
*1 The switching hub delay time changes depending on the switching hub model and settings.
*2 This is the device station with the largest calculation value when, for each device station, ("RX setting" / 8) + ("RWr setting"  2) is
calculated.
*3 The relation of dw (Total number of words) and p4 (RX/RY/RWr/RWw data transfer time) is as follows. (Station-based block data
assurance: When "not assured")
