grp.update sends to KNX?

[Thomas]

Hi,
according to documentation  grp.update(alias,var) should write directly into memory. "but does not send new value to TP bus"

But I see these writes in ETS diagnostics like they were send to KNX bus. Is this behavior intentional? 
It looks like grp.write and gro.update do the identical thing.
I don't want these datagrams. How to disable sending?

Hi,

There is a KNX telegram send over IP so ETS will show messages. However there is none on the twisted pair (TP).

TP is more critical for keeping clean as it can handle restricted amount of data, IP has not that restriction so makes no sense to reduce trafic on IP.

If you don't want the IP telegram send you can / should block it in the filter table.

I don't know if it's relevant but my LM is in TPUART mode and the KNX is programmed and debugged in ETS5 via LM

Thank you. 
In case these datagrams are not routed to TP in any way then it's OK.
