. Now I need to figure out how to distinguish publishers of this data... Is each publisher meant to have separate
Not sure if I have got the question. Filtering is implemented in the library, so you should not care about it. Filtering and data content is setup in the configuration.
You should use the couple (RepositoryGroup, ProcessValueName) to find where the value must be written. If your HMI interface need additional configuration the provided configuration should be expanded. For example:
RepositoryGroup = Boiler.1
ProcessValueName = PipeIn_Presure
You can use the simulator to display generated values on selected picture or place on the screen - don't touch the MessageHandlers configuration to make sure you are getting everything form the producer.
master. It needs harmonization of any derived libraries as the result of some minor architecture changes. The work on Rel 4 is underway so I cannot guarantee that the API will not change in future, but once more it is to be more stable for now.
repositoryGroup, and while it works locally (on single machine) I ran into issues with receiving this data on mobile device in local network I'll try to debug it now. I tried enabling events on EventSource of UDP message handler but I didn't receive any... I wonder whether it has to do with Mono's implementation of these.
Thanks for update. The critical point for logging the network traffic is application configuration, there is the switch:
<add name="System.Net.Sockets" value="Information" />
<!-- value: Required String attribute. Sets the verbosity of the output.
Legitimate values are Critical, Error, Verbose, Warning, and Information.
-->
<!-- maxdatasize: Optional Int32 attribute. Sets the maximum number of bytes of network data included in each line trace.
The default value is 1024.
-->
<!-- tracemode Optional String attribute. Set to includehex to show protocol traces in hexadecimal and text format.
Set to protocolonly to show only text. The default value is includehex.
-->
</switches>change Information to All
I've tested obtaining events from
UDPMessageHandlerSemanticEventSource and while in WPF application it works, on mono it doesn't. I'm also not sure how I'm suppposed to obtain its instance since Log property is internal. For now I've been using reflection to test (but it wasn't very helpful).I'll try importing UDP handler project manually and thoroughly see what's going on.
.xml config files sufficient? I'm now adding one more DataSetConfiguration with only AssociationName and RepositoryGroup changed. Additionaly I'm adding ProducerAssociationConfiguration entry with updated AssociationName to match the ones defined in DataSetConfiguration
IEncodingFactory is implemented by the code-base as .NET Standards so you can use it instead of implementing it. I don't see any reasons to rework this lib , or maybe I am not following you.
Wireshark. Let's think about a piece of software converting the producer configuration to consumer configuration - for example as a unit test. Yes .xml file consist all details for selected producer or consumer. In a few days I should have the configuration generator for the simulator I am working on. Maybe it helps. Lets think about conf call or F2F meeting - details we exchange by separate conversation by email.
The problem with library's implementation of
IEncodingFactory is that it forces repositoryGroup which is undesirable, I just made my own without this check.The problem with missing packets is that even though I'm changing producer configuration I only see data produced for 1st data set, I'll wait for this configuration generator while working on other stuff.
IEncodingFactory is required in case you need to provide a data converted.```C#
/// <summary>
/// Sets the converter, which is used to provide a way to apply custom logic to a binding.
/// </summary>
/// <value>The converter as an instance of the <see cref="IValueConverter"/>.</value>
IValueConverter Converter { set; }
~~
The check is redundant and may be simply removed - I will add issue addressing this
The
/// <summary>
/// Updates the value converter.
/// </summary>
/// <param name="binding">An object responsible to transfer the value between the message and ultimate destination in the repository.</param>
/// <param name="repositoryGroup">The repository group.</param>
/// <param name="sourceEncoding">The source encoding.</param>
/// <exception cref="ArgumentOutOfRangeException">
/// repositoryGroup
/// or
/// binding
/// </exception>
void IEncodingFactory.UpdateValueConverter(IBinding binding, string repositoryGroup, UATypeInfo sourceEncoding)is the pace where you can assign to the Converter property used by the library to handle additional type conversion if needed.
IBinding definition.
IEncodingFactoryEncodingFactoryBinarySimple has useless test of the repositoryGroup parameter. #304This fix should be committed today and will be available on
400.The Simulator development is really time consuming job, so the milestone is now overdue. There are two tricky point: making the simulator work and configuration generation. Hopefully I will PR to master a prototype at the beginning of the next week. So keep going focusing on your stuff.
@Drutol I am glad to say that the work on the factory (boilers set) simulator (alfa) is close to release. :simple_smile:
The starting point for boiler description is on the commsvr.com page:
Investigate also the document: section Custom model boiler
I will use this documents to prepare the simulator description, so you may read them in advance.
You may find also helpful downloading the
OPC UA Address Space Model Designer
It has the model attached as the embedded example.
The simulator documentation is planned as the #306 in the current milestone.
@Drutol My concern is how to provide the observed device coordinates. We must consider two scenarios:
- Localization is fixed, e.g. boiler - the coordinates may be provided in the HMI configuration file.
- It is a moving device, e.g. train - the current coordinates must be transmitted over the wire.
In 2 the coordinates must be modeled and encoded - importance level is as the timestamp. I must ask my OPC UA fellows if we have any standard representation of the GPS coordinates.
Are you aware of that? The first approach is 1. but we should be ready to accommodate 2.
App.BilersSet.xml. The simulator is loosely coupled with the ReferenceApplication. Hard references have been added to copy all assemblies during the build.Your next step is to prepare the configuration for the Consumer - it must be mirror of the producer configuration. Test it with the DataLogger before integration with your stuff. It should log all data cumming from the simulator.
My next task is to prepare a documentation, but because I have a few other challenging project ahead I must slow down. Keep me informed about the progress.
Let me know how it works for you.
@Drutol Good news. I haven't really tested the behavior of the boiler simulator . I have stolen it form the OPC Foundation stuff as is, but now my concern is where set points are provided. Anyway, the simulator is implemented in tempuri.org.UA.Examples.BoilerType.BoilerState:
/// <summary>
/// Updates the values for the simulation.
/// </summary>
private void DoSimulation(object state)
{
//....
}Note it is partial and located in at :
Networking\Simulator.Boiler\Model\BoilerState.cs
It seems that it was not implemented with real physic rules in mind, but it shout generate random data.
- First priority task is to prove that the communication doesn't generate any warnings in the log files (consumer and producer). Note, there are two log files -it is not perfect solution but ...it is.
- Next is to provide data from selected boiled on scree in real-time
- Improve simulator to behave as expected - our goal is not to simulate real boiler, but not all 0.0.
- Build a sophisticated mechanism to select one of the boilers in set using for visualization for example using observer (smartphone) geographical location.
If the configuration works fine, add the file to the DataLogger and PR back to me. Use similar name as for the producer.
Goo luck and inform me about success.
- As for warnings in log files... I don't see any.
Now how to deal with the geographical localization? As I sad we must consider two scenarios:
It is static, so it is not provided by the data transferred over the wire - it is HMI feature, so you must deal with it. Using the
repository nameis not the perfect solution (but possible), because it makes consumer/producer configuration synchronization very difficult. The OOI stuff is prepared for a situation like this by expanding the configuration file. An example you have inUANetworkingConfigurationUnitTest. I believe your work will be proof of concept in this respect. In your part of the configuration, you may add an array containing <key, value> pairs, where the key isrepository nameand value is geographical localization.It is dynamic (running train, rolling ball) the geo position must be provided as a variable with the
part of relationshipwith the object model. But now it is not the case. So let's fix the static solution, and after that, if we have time we will think about the UA model containing localization. BTW, I have forgotten to ask :-1: , sorry about that. Fortunately, having proof of concept for a static case we may inform about the success while asking about this particular detail :smile: .
GitHub Pages. They are visible even for private repositories, so I will be able to add ref to you stuff if you don't mind.
GitHub Pages... hmm I don't really feel like there's much to present there. Any specifics in mind? I've prepared the static website generator though so I'm pretty much ready to go.
ExtensionDataObject but I don't believe that this is what I'm looking for either. Also even if I do expand the configuration file I won't be given any data from the library when creating bindings for example so I would have to intercept the configuration somewhere anyway. Isn't it more feasible to create some other configuration file or just derive from existing ConfiguarationData class and forward extra data to some other component?
@Drutol I have added issue to your repository related to GitHub Pages.
Read more about GitHub Pages Basics.
GitHub Pages sites are publicly available on the internet, even if their repositories are private.
Therefore, GitHub Pages can be referenced by a link and available to the public community.
The content should follow the gist:

As the starting point use your RAEDME.md and the project description:
It should be cover page of your project. I have generated it from the README.md. See OOI
@Drutol configuration management followup:
I have reported a new issue:
The API I mentioned previously is dedicated to using the library as a component of a configuration editor. For the communication, it is not applicable, and the API is hard-coded so it must be modified. Let's assume the custom configuration must be derived from the ConfigurationData. Tomorrow afternoon I will provide a fix for that.
