You can set Preferred Servers, which will be displayed at the top of the list when  you launch Client (see Starting an Axxon One Client).

To do it, follow the steps below:

  1. Go to Settings → Options → Automatic connection (1–2).

  2. In the Saved servers group,  select the Server from the list (3).

  3. Change the default port if needed (4).

  4. Click Add (5). 

  5. Repeat the steps for all target Servers.
  6. Click Apply.

You can save the Preferred Servers list to a JSON file and load it to another Client (see Configuring Cross-System Client and autologon).
