Master station local station (Ver.2-compatible slave station)
■Master station (RX) (RWr) local station (RY) (RWw)
This is the time between the device of the CPU module in a local station turning on (off) and the device of the CPU module in
a master station turning on (off).
This is also the time between data set in the device of the CPU module in a local station and the data stored into the device of
the CPU module in a master station.
The following table lists the calculation formulas.

The letters in the table mean as follows.
SM: Master station sequence scan time
LS: Link scan time
SL: Local station sequence scan time
n: LS SM (The decimal point is rounded up.)
t: LS m SM (The decimal point is rounded up.)

Master station intelligent device station
Transmission delay time between a master station and an intelligent device station varies depending on the intelligent device
station.
Refer to the user's manual for the intelligent device module used.
