[Data link startup]
1) When the personal computer is powered on, the CC-Link system automatically
starts up in accordance with the network parameters set by the CC-Link Ver.2
utility.
[On/off information from a local station to the master station or another
local station]
2) The on/off information of the CPU device set with automatic refresh
parameters is stored in the "remote output RY" buffer memory of a local station.
The remote output RY is used as the output information to be used by the local
station system.
3) The information in the "remote output RY" buffer memory of the local station is
automatically stored (for each link scan) in the "remote input RX" buffer
memory of the master station and the "remote output RY" buffer memory of
another local station.
4) The program uses the mdReceive function to read the input status stored in
the "remote input RX" buffer memory.
The remote input RX is used as the input information to be used by the local
station systems.
5) The input status stored in the "remote output RY" buffer memory is stored in
the CPU device set with automatic refresh parameters.
