APPENDIX
[2] In the case of block data assurance per station is enabled
(1) Master station (CC-Link Ver.2 board) remote I/O station
(a) Master station (CC-Link Ver.2 board) (RX) Remote I/O
station (input)
The following formula indicates the time taken from the moment a signal is
input to the remote I/O station until RX of the master station (CC-Link Ver.2
board) turns on (off).
[Formula]
[Normal value]
Iu + α 1 + (LR m) + (LS 1) + Remote I/O station response time [ms] ( 1)
[Maximum value]
Iu + α 1 + (LR m) + (LS 2) + Remote I/O station response time [ms] ( 1)
Iu : Reading execution interval of the user program
α 1: 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)
1: 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.
(b) Master station (CC-Link Ver.2 board) (RY) Remote I/O
station (output)
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 I/O
station output turns on (off).
[Formula]
[Normal value]
α 1 + (LR m) + (LS 1) + Remote I/O station response time [ms] ( 2)
[Maximum value]
α 1 + (LR m) + (LS 2) + Remote I/O station response time [ms] ( 2)
α 1: 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)
2: 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.
