How to perform Loxone Miniserver extension diagnostics?

If you are performing a diagnostics of the extensions, there is a visual error checkup or a link diagnostic from the Loxone Config.

The visual Status LED error check can be performed fast and easy:

• LED red flashing - no Miniserver connection, re-check the wiring
• LED orange flashing - the connection to the Miniserver is ok, but is not added to the program
• LED green flashing - the extension is online and functioning
• LED orange/red flashing - update transmission
• LED quick red/green flashing - the extension is selected in the Loxone Config and is identifying
• LED not flashing - check the power supply

The diagnostics can provide a far more detailed analysis. You need to connect to the Miniserver, the device with the Link interface, and click the "Link Diagnostics" button.

All of the extensions are listed in the Diagnostics window and diagnostics data is transmitted continuously. The data can be used to detect any errors, and they are displayed accordingly.

I am going to explain here the most common issues that are happening and how to check/solve them.

If any of your extensions are having LED flashing orange and it doesn't show up in the Loxone Config, some of the following reasons might be the problem:

Problem 1: The Miniserver is not seeing the extension connected because it might not be added to the program.

Solution: Connect to the Miniserver and load the file, check the periphery tree for that extension and inspect the serial number if it is correct. If this still doesn't solve it, check the second problem.

Problem 2: Extension is added to the program but the problem remains and is not showing up in the search

Solution: Reboot your Miniserver and the extensions (the green power plug connector should not be removed if the power supply is on). Switch off the power supply and check if the Loxone blue connector is correctly plugged in or damaged. Check if the last extension is terminated with a 120 Ohm resistor. If you have multiple power supplies, make sure that the grounds to all of them are connected.

Problem 3: If the wiring is corrected and the reboot didn't solve the problem, check the resistance with no power turned on.

Solution: Measure the resistance between the two terminals of the blue connector with a multimeter. If the value is a lot different and the wiring is all correct, you need to contact the support team.
