HomeServer and 4 bytes input value

[dragan.lazic]

Hallo,
Ich habe ein Problem mit der Deutung von 4 BytefeuchtigkeitsWerten und Darstellung im FacilityServer.
Der Enthalpie-Sensor (RTS Automatisierung) hat nur 4 Bytegegenstände für Feuchtigkeit.
Ich brauche diesen FeuchtigkeitsWert für Vusualisation.
Wie man richtig diesen Wert liest?
Ich möchte unterstreichen, daß es nicht möglich ist, die ein 4 Byteswert zum 2 Byteswert in der Sensor-Anwendersoftware zu ändern.
Z.B. Wert: 42 3A ED 32 was 46.73164%RH ist, FacilityServer liest als die Hexagonzahl und -anzeige: 1111158066
Selbstverständlich kann ich alles im ETS richtig lesen.
Die Antwort von hotline@gira.de ist das FacilityServer kann nicht das im Moment automatisch tun.
Wie ich die Lösung sehe:
Ich muß den KNX Algorithmus finden, dass 4 Byte -> Float Umwandlung (mantisa, Exponent,…), und Versuch
eine Logikfunktion im FacilityServer zu shaffen um 4 Bytes zum Float umzuwandeln.

Hat jemand möglicherweise dass shoen gemacht?
Danke.
Bester Respekt,
Dragan Lazic

I hope the Google translation is OK.
What I puted to the Google is:

Hello,
I have a problem with 4 bytes humidity values interpretation and presentation in the FacilityServer.
The enthalpy sensor (RTS Automation) has 4 bytes objects for humidity only. I need that humidity value for visualisation.
How to read correctly that value? I would like to underline that It is not possible to change that (4 bytes to 2 bytes) in the sensor application software.

For example value: 42 3A ED 32 what is 46.73164%RH, FacilityServer reads as the hex number and display: 1111158066
Of course I can read everything correctly in the ETS.
The answer from hotline@gira.de is the FacilityServer can not do that automatically in the moment.

How I see the solution:
I have to find the KNX algorithm for the bytes -> float conversion (mantisa, exponent, ...) and try to make logic function in the FacilityServer for that purpose - to convert 4 bytes to the float value.

Maybe somebody has something already made

Thank you.
Best regards,

Hi Dragan,

it is easier than you think:

HS/FS internally use only ONE number format. So it is possible to even add binary values.

So you could use a binary trigger - or even easier to explain:

a "Multiplikation" times 1

4byteValue x 1 = 2byteValue

All you have to do is to choose the right data format for the two communication objects.

Conversion will be done "by design"

Hi Matthias,
thanks for help.
But something is not OK.
I will try to explaine.

I read by ETS the humidity value 40.67745
That number in HEX 4 bytes notation is 42 22 B5 B5 (I read that value in ETS also)

Facility Server read (data type: 32-Bit (0..21474836647/EIS 11) that value as 1109570997 what is equal to the 0x4222B5B5. I think that is OK and the normal behaviour.

That means FS reads a very big value.
When I multiple that big value with 1 (as you said) and put the result in 2 bytes object I obtain the saturation 16 bits value: 65535 - max. value.

Everything is like I expected.
I am affraid that I did not explain my problem correctly, or I did not understand you.

Thank you again.

Waiting for more help.
Best regards,
Dragan

On my Facility server 4byte means EIS 9!?

Not 32bit, but 4-byte!

Do you mean this Facility Server:

A

or this one:

B

[dragan.lazic]

I have just two 32-bits data type.
Both of them are of EIS 11 type?

Dragan

[Matthias Schmidt]

Again, which one, A or B? :)

[dragan.lazic]

In my home I have HS 3,
but on project I am working now, I have 6 Facility Server, your figure A.

[dragan.lazic]

But I do not understand you.
What I can see is HS 2 V2.1 Experte.
Maybe the HS Experte is the problem, last version, of something like that.
I use the same HS Experte for my HS3, and FacilityServers

[Matthias Schmidt]

Hast du nicht 4-byte Floating point EIS9?

Don't you have 4byte floating point EIS 9?

[dragan.lazic]

I do not have that data type.
It is very dificulte to attach a file.
All menus are in German. I will try

1391

[Matthias Schmidt]

Oha, what Firmware do you use?

You can find it on debug page.

[dragan.lazic]

Version2.1.061108

[Matthias Schmidt]

Ok.

My FS runs a Beta firmware, thats the reason why I have this data types and you do not.

This new firmware will be available very soon and I think you will be able to solve your5 problem then!

[dragan.lazic]

FacilityServers are 20 days old. I assume that I have the last firmware version.

My HS 3 is one of the first from the beginig of the year, but I did not change HS Experte!

Question:
Is it possible to use old HS Expert with new firmware?
Maybe that is my problem?

No, it is not!

[dragan.lazic]

Thank you for your time and help.
I will wait the new firmware.
I hope it will come soon.

I must finish my project till the end of the next mount.
