The data link can also be started from the parameters written in the "parameter data area" in
the buffer memory. (Refer to chapter 6.)

...The last 2 bits cannot be used when the master station and the local station are communicating.
[Data link startup]
Turn on the refresh specification (Yn0) and make the remote output (RY) data valid.

When the refresh specification (Yn0) is off, all the remote output (RY) data is treated
as 0 (off).
Turn on the data link startup by the E

link.
However, the parameters must be set in the E
When the data link is started normally, the host data link status (Xn1) turns on.
[On/off data from remote I/O station/remote device station/local station
station]
The input of remote I/O station, remote input (RX) of the remote device station and
3
the remote output (RY) of the local station are automatically (for each link scan)
stored in the master station's "remote input (RX)" in the buffer memory and local
station's "remote output (RY)" in the buffer memory.
The data in local station's "remote output (RY)" is also stored in other local station's
4
"remote output (RY)".
The input status stored in the "remote input (RY)" in the buffer memory is written to
5
the PC CPU with the FROM instruction.
