(3) Master station (CC-Link Ver.2 board)
(programmable controller) (Ver.2 compatible slave station)
(a) Master station (CC-Link Ver.2 board) (RX)
(programmable controller) (RY)
The following formula indicates the time taken from the moment a local
station's CPU device turns on (off) until RX of the master station (CC-Link
Ver.2 board) turns on (off).
[Formula]
[Normal value]
LS (1 (2 n-1)+1) + SL [ms]
LS: Link scan time (refer to Appendix 3.1)
SL: Local station sequence program scan time
n: Expanded cyclic setting (n time setup)
Note that n=1 is used for a Ver.1 compatible slave station.
(Example) When the link scan time is 3 ms and the expanded cyclic setting is
"double" and the local station's sequence scan time is 10 ms:
LS (1 (2 n-1)+1) + SL [ms]
= 3
= 22 [ms]
[Maximum value]
LS (2 (2 n-1)+1) + SL [ms]
LS: Link scan time (refer to Appendix 3.1)
SL: Local station sequence program scan time
n: Expanded cyclic setting (n time setup)
Note that n=1 is used for a Ver.1 compatible slave station.
(Example) When the link scan time is 3 ms and the expanded cyclic setting is
"double" and the local station's sequence scan time is 10 ms:
LS (2 (2 n-1)+1) + SL [ms]
= 3
= 31 [ms]
1: The above one is shown by the example of the remote device station (RX，
RY), but it is also applicable for the remote device station (RWr，RWw).
2: When reading RX from the CC-Link Ver.2 board with the md function, it is
necessary to add the own station access processing time of the md function.
(1 (2 2-1)+1) + 10
