Duplicate DALI addresses

[VaidasM]

Hello, 

I'm using MTN6725-004 and very interesting problem appeared - after random addressing, two lamps have the same ID, at least I guess so, because when I'm testing with blinking, blinks two lamps at  the same time. It is 37 Dali lamps on the line, so it is far from limit and there 2 duplicate groups on this line, both of them have 2 lamps. As I did not find how I can change short address manually with ETS5 plugin, wanted to ask how to solve this problem? 

I thought that when I'm initializing Dali lamps, MTN6725 deletes longs and short addresses, then creates long random addresses, after that align from smallest to highest numbers and gives short addresses. So does this means, that long random addresses duplicated also?

If there would be possibility to write address manually, I would disconnect single lamp from group and manually write the address.

Thank you.

Hello

Your thoughts are correct: Our DALI gateway during new installation process is deleting all existing DALI long and short addresses and is creating new ones. No DALI long or short address is created twice.

So I wonder how this could have happened in your case. A possible reason is that the affected ECG had been addressed before and during commiccioning with our DALI gateway it is not found or refuses to change the address. You also have to distinguish between controlling the ECG on group level or single ECG level. When bringing a group to blinking mode then of course all members of this group have to react.

manual changing of DALI short address is not possible with the DALI gateway. To overcome the situation you should run "new installation" process once again. Hopefully the result this time is providing better result.

A way to change the DALI short address could be to use a DALI tool that is able to directly communicate with the ECG. Such tool for example is offered by company Tridonic (manufacturer of ECGs) free of charge. The name of the Tridonic tool is "masterCONFIGURATOR". But to be able to communicate to the DALI line you will need a DALI USB interface. 

This tool you can also use to monitor the DALI communication. So if second new installation process shows the same result having duplicate DALI addresses you could monitor the DALI communication during new installation process and forward it to me. I then could check if we see errors during DALI addresssing or could see duplicate addresses.

Hello again, 

wanted to ask about the same gateway MTN6725-004. This time I can not read integrated presence sensors Osram AA3299101G3. I know for sure, that sensors are working, because I've tried to read with Wago controller and succeeded, so I assume that I do not know something about ETS5 DCA part. I use "New installation" button and it does not find sensors on line, only lamps appear.

Thank you.

Hello VaidasM,

it seems you are working with our MTN6725-0004 KNX DALI-Gateway Basic REG-K/2/16/64.

This do not support the cowork with DALI2-Sensor devices.

This functionality is supported by our MTN6725-0101 SpaceLogic KNX DALI Gateway Pro 1ch DALI-2.

Please double check that your DALI-Sensor-Product is really DALI2-certified.

Hello again

The DALI Gateway Basic MTN6725-0004 does not support DALI sensors. Only our DALI Gatweay Pro MTN6725-0101 is supporting DALI sensors. That's why you will only see ECGs when doing a DALI line scan with MTN6725-0004.

Best regards
