(b) Master station (CC-Link Ver.2 board) (RY)
station (RY)
The following formula indicates the time taken from the moment RY of the
master station (CC-Link Ver.2 board) turns on (off) until the remote device
station output turns on (off).
[Formula]
[Normal value]
LS (1 (2 n-1)+1) + Remote device station processing time [ms]
LS: Link scan time (refer to Appendix 3.1)
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 remote device station processing time is 1.5 ms:
LS (1 (2 n-1)+1) + Remote device station processing time [ms]
= 3
= 13.5 [ms]
[Maximum value]
LS (2 (2 n-1)+1) + Remote device station processing time [ms]
LS: Link scan time (refer to Appendix 3.1)
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 remote device station processing time is 1.5 ms:
LS (2 (2 n-1)+1) + Remote device station processing time [ms]
= 3
= 22.5 [ms]
3: The above one is shown by the example of the remote device station (RY),
but it is also applicable for the remote device station (RWw).
4: When writing RY to 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) + 1.5
(2 (2 2-1)+1) + 1.5
