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 value
Station-based block data assurance used
(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.
Calculation value
Station-based block data assurance used

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
