HS/FS Wert nach start Abfragen Fehler

[bramlangen]

Hallo zusammen!
My issue appears to be the same as the one mentioned in this thread - but the suggestions there do not resolve the issue for me. From another thread I read that the scan-fehler issue was a bug in 4.2 - so I upgraded today to 4.5. However, the issue is still there.

The issue:

• When rebooting, the KOs which have the flag set to "Wert nach start Abfragen" are being read. The ETS group monitor sees the request as well as the response - three times in a row. The HS does not see the response for the first dozen or so read requests.
• I removed the 'Abfragen' haken for the KOs listed in the scan-fehler field of the debug page. After a reboot there are now other KOs listed, those indeed still have the 'Abfragen' haken as they did not show up in the scan-fehler listing.
• I have some KOs that are requested using logic, shortly after the reboot. The responses to those requests are coming in just fine. Anytime after the reboot any read request will also be seen by the HS right away.
• ==> It appears that the HS does not see any responses of read requests that have been requested early on in the reboot process. Any request made later on registers just fine. Right now, the first 11 requests fail, the remaining 4 get a successful response.

Configuration:

• Only a single line (2.1.x), with only a dozen components. A Gira IP router model 1030 is in place, address 2.1.0. The router is set to pass any and all telegrams both ways.
• HS3, firmware 4.5. Experte 4.5. The project is small, only about 5% of the memory used. The HS communicates using EIBNet/IP routing.
  (the physical address of the HS is 2.1.65, which is not correct I think, but I doubt that would be the issue - I only gave it that number so that ETS would think it is in the same line.)
• Router and HS are in the same LAN.

Any thoughts?

Thanks, Bram
