TP Repeats

[rocfusion]

Hi,

Is there way to get the LM to log the TP Repeats?

Thanks,

Roger

Number of TP repeats can be seen in KNX statistics. There's also knxlib.getstats() function available in RC4. It returns a table with bus stats, including TP repeats.

Ok that's cool, but can we see which telegrams have been repeated, showing the source and destination of the telegram. This would be useful for diagnosing problematic KNX buses.

Thanks,

Roger

Hi,

A strange thing happens to me, I have many repeteciones and the load of the bus is low, there are more repetitions than load. It is a small installation, and if I monitor the bus everything is correct. I have a script that runs every 5s and sends only 7 group addresses with delays of 0.2s.

What can happen?

Thanks

Repeats are probably coming from scripts that use grp.write to a group address that is not assigned to a real KNX device. You should either use virtual objects or grp.update in this case.

also, if you have only sensor in line w/o any actors you will have the same problem.
in that case you can activate "ACK all group telegrams" option in network - knx connection menu

Yes!! that was the problem!
Thank you

Hello, can someone help me, do you know why these repetitions occur on the bus after you activate a 1-bit group address?

[admin]

Repeats will happen if you are sending any value to TP bus and there's no other device that has the same group address assigned to it. If you don't need this value on the bus then use either virtual objects or grp.update in scripts.

Your telegrams are not acked. Therefore the sender (a line coupler?) sends every packet five times. Set Ack All at your LM.
