Description
Master station sequence scan time

Round up the calculated value to the nearest integer of (SM  LS)
Loop 2 Detailed explanation
No.5 to If the conditions of No.6 and No.7 are both met, assign the
No.10 group number j to the ith station.

 
 After a group number has been assigned to all stations with
"CC-Link IE TSN Class A" whose "Communication Period
Setting" is "Low-Speed", determine the maximum value J of the
group numbers.

The following formula is used to determine the number n.
Value of n = J  4 rounded up to the nearest integer
