■ Variable
For each variable to be used, round it up to one decimal point before assigning to the calculation formula.
Item Calculation formula

speed cycle does not exist The largest value in items No.1 to No.3 + No.4
When a CC-Link IE TSN Class A slave station with the basic cycle or normal
speed cycle exists No.1 + (the value in No.2 or No.3, whichever is larger) + No.4 + No.5
