FX2N-64CL-M CC-Link/LT Master Block Data Link Processing Time 9
9-2
9.1.2 Transmission delay time
The transmission delay time (the time until data is received) (including the time for
communication between the main unit and FX
2N
-64CL-M) can be calculated by the following
formula.
1) Master station
←
Remote station (input)
Time until a device (X) in the main unit turns ON or OFF after a signal is input to the remote
station
Calculation formula
SM
×
2 + (2 - n)
*1
×
LS + Remote station input response time [ms]
SM: Scan time of master station PLC
LS: Link scan time
n: SM/LS (whose decimals are omitted)
*1: 0 if the value "2-n" is 0 or less
Example:
The scan time of the master station PLC is 5 ms, the link scan time is 1.2 ms, and the input
response time of the remote I/O station is 1.5 ms

2 + (2 - n)

LS + Remote station input response time [ms]
= 5
×
2 + (2 - 4)
×
1.2 + 1.5 [n = 4 (5/1.2 = 4.16..., then decimals are omitted)]
= 11.5 [ms]
2) Master station
→
Remote station (output)
Time until an output in the remote station turns ON or OFF after a device (Y) in the main
unit is set to ON or OFF
Calculation formula
SM + LS
×
2 + Remote station output response time [ms]
SM: Scan time of master station PLC
LS: Link scan time
Example:
The scan time of the master station PLC is 5 ms, the link scan time is 1.2 ms, and the output
response time of the remote I/O station is 0.5 ms
SM + LS
×
2 + Remote station output response time [ms]
= 5 + 1.2
×
2 + 0.5
= 7.9 [ms]
