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

[Data link startup]
Turn on the refresh specification (Yn0) and make the remote output (RY) data valid.
1
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
2
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 local station
With the TO instruction, write the on/off data to be sent to the master and other local
3
stations to the local station's "remote output (RY)" in the buffer memory.
The data in local station's "remote output (RY)" in the buffer memory is
4
automatically (for each link scan) stored in the master station's "remote input (RX)"
in the buffer memory and other local station's "remote output (RY)" in the buffer
memory.
The input status stored in the "remote input (RX)" in the buffer memory is received
5
to the PC CPU with the FROM instruction.
The input status stored in the "remote output (RY)" in the buffer memory is received
6
to the PC CPU with the FROM instruction.
