Fig. 1. The main window.
When you click the Add button 
, a window will be displayed with the connection settings for each data source (if required) and tag parameters (see Fig. 2). The parameters of each connection type are described in more detail in the sections below.
For each connection, it is possible to configure certain transmission directions 
. For example, you can enable only one-way data transmission or temporarily disable communication.
Fig. 2. Tag linking parameters.
After setting up a new link of tags and clicking OK in the settings window, a new connection will appear in the main window (Fig. 2). Once you have configured the list of all connections, click File - Save 
to apply all the changes. The next time you run the program, the last saved configuration will be loaded.
By pressing the Pause button
on the toolbar, you will temporarily suspend the program.
In the Status column the symbol "<" or ">" will appear indicating transmission from one source to the other.
Furthermore, you can configure the program parameters in a separate window (message log, service mode, data display type, etc.).
