Master station  remote device station (Ver.1-compatible slave station)
■Master station (RX) (RWr)  remote device station (RX) (RWr)
This is the time between a signal input to a remote device station and the device of a CPU module turning on (off) or the time
until the data in the device of a CPU module is changed.
The following table lists the calculation formulas.
Calculation Station-based block data assurance used
value

sequence scan
(SM  n) + (LS  1) + Rd
Normal value
(SM  n) + (LS  2) + Rd
Max. value
The letters in the table mean as follows.
SM: Master station sequence scan time
LS: Link scan time
n: LS  SM (The decimal point is rounded up.)
Rd: Remote device station processing time
■Master station (RY) (RWw)  remote device station (RY) (RWw)
This is the time between the device of a CPU module turning on (off) and the output of a remote device station turning on (off)
or between data set in the device of a CPU module and the data in a remote device station changed.
The following table lists the calculation formulas.
