APPENDICES
(3) Refresh Devices
In redundant systems, refresh of remote inputs (RX), remote outputs (RY) and remote
registers (RWr, RWw) are set with the program.
Refresh settings of special relays (SB) and special registers (SW) are configured with
network parameters.
The CC-Link refresh devices and refresh ranges for the system in Appendix 4.1 (using
5 stations) are shown in Table App.12.
Change the transfer range on the CC-Link side, and the device range on the CPU
side to match them with the number of stations and module types on the system used.
* 1: Indicates the number of transferred data that is specified in the BMOV instruction.
