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 "RX 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"

*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")
