(8) Writing of remote output (RY)
(1)
Create a program that instructs CC-Link refreshing and then starts the data link
after the parameters are set. (Refer to section 5.4.)
after the parameters are set. (Refer to section 5.4.)
(2)
Create the following program, and read RXn0 to RX(n+1)F into X100 to X11F.
Module error (master station)
Module ready (master station)
Local station data link state (master station)
Changeover to bank 0
Read 'RXn0 to RX(n+1)F'
to 'X100 to X11F'
to 'X100 to X11F'
POINT
When using QCPU (Q mode) or QnACPU, setting automatic refresh parameters
refreshes the contents of the remote input (RX) and remote output (RY)
automatically. Thus, the above program is not required.
