(b) Master station (CC-Link Ver.2 board) (RY)
(programmable controller) (RX)
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 local station's
CPU device turns on (off).
[Formula]
[Normal value]
α1 + (LR m) + LS
[Maximum value]
α1 + (LR m) + LS
α1: Request processing time of the personal computer
LR: Link refresh time
LS: Link scan time (refer to Appendix 3.1)
SL: Local station sequence program scan time
k: LS/SL (However, the decimal point is rounded up)
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.
3: 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).
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.
(4) Master station (CC-Link Ver.2 board)
The transmission delay time between the master station (CC-Link Ver.2 board)
and the intelligent device station varies depending on the type of intelligent
device station used.
Refer to the User's Manual for the intelligent device module to be used.
Notes
When reading RX and RWr 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.
When writing RY and RWw 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.
POINT
The own station access processing time by the md function varies depending on
the performance of the personal computer, load status and other factors.
