Transmission delay time of cyclic transmission
This section shows the transmission delay time of cyclic transmission.
When the local station is a C Controller module, change SL to the following processing time.
• SL=P=R+α
P: Processing time on a C Controller system
R: Refresh cycle
α: Link refresh time
When the local station is this product, use direct access to the link device or buffer memory access. Change
SL to the processing time of the function.
In case of a master station and intelligent device station / remote device station
■Master station (RX, RWr) ← intelligent device station/remote device station (input)
Times are shown below.
• The time from signal input into the intelligent device station / remote device station until the link device of the master station
is turned ON or OFF
• The time from data input into the intelligent device station / remote device station until data is stored in the link device of the
master station

CT: Synchronous communication cycle
Rio: Processing time of intelligent device station / remote device station (Manual of intelligent device station / remote
device station being used)
■Master station (RY, RWw) → intelligent device station/remote device station (output)
Times are shown below.
• The time from when the link device of the master station is turned ON or OFF until the output of the intelligent device station
/ remote device station is turned ON or OFF.
• The time from data setting to the link device of the master station until data is output to the intelligent device station / remote
device station
