(2) Master station (CC-Link Ver.2 board)
(Ver.2 compatible slave station)
(a) Master station (CC-Link Ver.2 board) (RX)
station (RX)
The following formula indicates the time taken from the moment a signal is
input to the remote device station until RX of the master station (CC-Link
Ver.2 board) turns on (off).
[Formula]
[Normal value]
Iu + α1 + (LR
[ms]
[Maximum value]
Iu + α1 + (LR
[ms]
Iu : Reading execution interval of the user program
α1: Request processing time of the personal computer
LR: Link refresh time
LS: Link scan time (refer to Appendix 3.1)
m: LS/LR (However, the decimal point is rounded up)
n: Expanded cyclic setting (n time setup)
Note that n=1 is used for a Ver.1 compatible slave station.
1: The above one is shown by the example of the remote device station (RX),
but it is also applicable for the remote device station (RWr).
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.
m) + {LS 1 (2 n - 1)} + Remote I/O station response time
m) + {LS 2 (2 n - 1)} + Remote I/O station response time
