Starting communication in the "Master" program

Danger of injury due to uncontrolled valve positions at communication start!
The DDLfWin software controls valves and, if necessary, changes the output values.
Ensure the operational safety of the system before starting communication!
To start communication:
Click on "DDL scan"
The following "Messages" dialog mask will appear with a warning.
Confirm that you have read and understood the warning by clicking on "OK".
The "DDL scan process" will start.
The software starts the cyclical data query. It recognizes the addresses set for all connected devices
and enters them in the "Available slaves" field.
The following error message will appear if you have started the "DDL scan" process and the baud
rate set in the software does not correspond to the DDL line:
1. Confirm the warning with "OK" and click on "Connection > DDL stop" to edit the "Interface
settings" mask.
2. Check that the same baud rate is set on all the DIP switches for the connected devices.
3. Set the baud rate of the DDL line in the "Baud rate" field.
4. Make sure that the power supply has been correctly connected and all plugs properly inserted.
To interrupt a running "DDL scan":
Click on "Stop" in the "DDL scan" mask.
The "DDL scan" mask will close and all of the previously recognized devices will be entered in
the device list in the "Available slaves" field.
