Operation overview
After a connection has been opened, the workstation uses MEWTOCOL-COM to send data to the ET-
LAN unit, and writes it to the DT0 of the programmable controller.
On the programmable controller side, initialization processing and open processing of the ET-LAN unit
are carried out, and „01" is set as the MEWTOCOL station number.
Usage method
1. Compile the sample program and create the execution file.
2. Enter the RUN mode on the programmable controller side.
3. Run the sample program.
4. When the connection is successfully opened, the sample program displays the following menu and
waits for input.
5. Pressing "0" at this points writes "0H" to DT0 (check this on the programmable controller side).
6. Pressing "1" at this point writes "FFFFH" to DT0 (check this on the programmable controller side).
7. Pressing "E" at this point disconnects the line and exists the program.
