A
Link scan time
The following is a calculation formula for the link refresh time. (when the link scan mode is asynchronous)
Transmission delay time
The following are the calculation formulas for the transmission delay time.
Master station (RX)
←
Slave station (input)
The following table shows the time after a signal is input to the slave station until the board device of the master station turns
ON or OFF.
SM: Master station link refresh time
LS : Link scan time
Master station (RY)
→
Slave station (output)
The following table shows the time after the board device is turned ON or OFF until the output of the slave station is turned
ON or OFF.
SM: Master station link refresh time
LS : Link scan time
Item Cyclic transmission mode
Normal mode High speed mode
Ka 25.8 • When "Turn OFF or 0 Clear Input Data (RX/RY)" is set
in the network operation setting: 18.5
• When "Hold Input Data (RX/RY)" is set in the network
operation setting: 9.75

(Maximum data link processing time when
disconnecting from network or reconnecting to
network) • When the serial number (first five digits) of the master station is '17022' or higher: Number of
disconnected stations × 3500
• When the serial number (first five digits) of the master station is '17021' or lower: 9000 + Total number of
ports used in the switching hub × 3000 (9000 when the switching hub is not used)
