Changing Property Values via OPC-UA about package-explorer HOT 9 OPEN

Hi,
thank you! This is a bug (or at least not intended behavior). Actually, our goal is to provide reading / writing OPC UA and yes, also REST reading / writing. In some point in time, I remember the OPC UA write already working, so it must have regressed.

So, for OPC UA I was now adding in AasEntityBuilder.cs:CreateAddPropertyState() for a x = new PropertyState(..) to have:
x.AccessLevel = AccessLevels.CurrentReadOrWrite;
x.UserAccessLevel = AccessLevels.CurrentReadOrWrite;

Using this, I can write to "normal" AAS Properties. This should cover most of the relevant variables in the AAS mapping, but I am not completely sure. So, please test for desired behaviour.

Currently, I have the change in "MIHO/FixChangePropertiesOPCUA". I will try to PR it to master ASAP.

Best,

Okay, this was up to now not my intended scenario ;-)
I take this as a feature request and will leave the issue open.
I will update you via here.

For the off-topic topic ,-)
Type 1: You have multiple SDKs available for (automatically) manipulating AASX as a file .. see: SDKs
Type 2: You can serve one or more AASes OPC UA, REST (and more?) and manipulate them as a server.
Type 3: Via "language of I4.0", you can have an agent-like approach of AASes interacting with each other.
What is your interest?

Hi,

thank you for your reply :).
Still having problems. I can change the values via ua-expert. However, changes aren't applied to the .aasx file. Restarting the server just resets the values.

Oh okay, thank you.

Off-Topic:
Is there a way to change the property values of the .aasx in any way (not manually with the explorer). We would like to write data from a machine (rotation of a certain module, temperature etc) to the property values from the aasx. These values change over time. Right now the .aasx is pretty much a static file. Or is that something that will be added in future?

Hey Michael,

I chose type 2: after a bit of testing, it looks like I finally found a way of changing property values via REST. My json was incorrect, which lead to a few errors -> it would create empty Submodelelements.
Sorry for the inconvenience and thank you for your help. 👍

Hello @MichaelHoffmeisterFesto ,

I am with the same problem: I can read and write propreties values using uaexpert, however changes aren't applied to the .aasx file. Restarting the server just resets the values. Is there any news concerning this issue?

Hello @gustavocainelli and @MichaelHoffmeisterFesto I have a same problem as you. Did you solved it ?

hi @pecanek01. Actually I was not able to solve that. Now I am using open62541 server. I build a xml file with the nodes that I need and the nodeset compiler generate the files nedded. https://open62541.org/doc/current/nodeset_compiler.html

But still, you can write new values using an OPC UA client, but if you reset the server, then the values are also reseted.
