It is possible that there are errors but you do not see them, because errors in Live Mapping do not always automatically throw exceptions.

Please study this: opclabs.doc-that.com/files/onlinedocs/QuickOpc/2016.2/User%2...n%20the%20Mapper%20Object.html

and rule out the situations described there.

Most importantly:

1. For the same data, map an additional member with Kind = UADataMappingKind.Exception, and check whether it gets null or a non-null Exception after the Write.

2. Hook to the mapper's UpdateFailure event and check whether it isn't raised during the Write.

Regards

No I did not reverse it, but unfortunately i picked the wrong property, which was actually not writeable. I will update this here

Ignored

Code:

    [UANamespace("CODESYSSPV3/3S/IecVarAccess"), UAType]
    public class MappedIoAnalog : BindablePropertyBase
    {
        private double actualValue;
 
        [UANode(BrowsePath = ".Actual_Value"),
        UAData(Operations = UADataMappingOperations.All, Kind = UADataMappingKind.Value),
        UAMonitoring(SamplingInterval = 250), UASubscription(PublishingInterval = 500)]
        public double ActualValue
        {
            get { return actualValue; }
            set { SetProperty(ref actualValue, value); }
        }
   }
}

Write successfull

Code:

    [UANamespace("CODESYSSPV3/3S/IecVarAccess")]
    [UAType]
    public class MappedMotionAxis : BindablePropertyBase
    {
        private AxisControl controlProperties = new AxisControl();
 
        [UANode(BrowsePath = ".control")]
        public AxisControl ControlProperties => controlProperties;
    }
 
  [UANamespace("CODESYSSPV3/3S/IecVarAccess")]
    [UAType]
    public class AxisControl : BindablePropertyBase
    {             
        private double setPosition;
 
        [UANode(BrowsePath = ".Set_position"),
         UAData(Operations = UADataMappingOperations.All, Kind = UADataMappingKind.Value),
         UAMonitoring(SamplingInterval = 250), UASubscription(PublishingInterval = 500)]
        public double SetPosition
        {
            get { return setPosition; }
            set { SetProperty(ref setPosition, value); }
        }
    }

Are you sure that classes aren't reversed in your post - the one that writes and the one that does not?

For writing to work, the Operations should include UADataMappingOperations.Write.

In your first class, you have Operations = UADataMappingOperations.All.
In your second class, you have Operations = UADataMappingOperations.ReadAndSubscribe.

So, I would expect the first class to do the Write but not the second.

Write of mapped Properties was created by Captain_Dash

Hello,

I have two classes with properties which i mapped succesfully, which means i can read the correct data from the server. Now I want to change properties and write the values to the server for each class. After Calling simply the client.write() methode one class is able to write on the server, the other ignores the writing without a message.

Following the structure of the two classes, with reduced properties

The one which will be ignored:

Code:

    [UANamespace("CODESYSSPV3/3S/IecVarAccess"), UAType]
    public class MappedIoAnalog : BindablePropertyBase
    {
        private double actualValue;

        [UANode(BrowsePath = ".Actual_Value"),
        UAData(Operations = UADataMappingOperations.All, Kind = UADataMappingKind.Value),
        UAMonitoring(SamplingInterval = 250), UASubscription(PublishingInterval = 500)]
        public double ActualValue
        {
            get { return actualValue; }
            set { SetProperty(ref actualValue, value); }
        }
   }
}

The one which will write, the class :

Code:

    [UANamespace("CODESYSSPV3/3S/IecVarAccess")]
    [UAType]
    public class MappedMotionAxis : BindablePropertyBase
    {
        private AxisControl controlProperties = new AxisControl();
    
        [UANode(BrowsePath = ".control")]
        public AxisControl ControlProperties => controlProperties;
    }

  [UANamespace("CODESYSSPV3/3S/IecVarAccess")]
    [UAType]
    public class AxisControl : BindablePropertyBase
    {             
        private double currentPosition;
       
        [UANode(BrowsePath = ".Current_position"),
         UAData(Operations = UADataMappingOperations.ReadAndSubscribe, Kind = UADataMappingKind.Value),
         UAMonitoring(SamplingInterval = 250), UASubscription(PublishingInterval = 500)]
        public double CurrentPosition
        {
            get { return currentPosition; }
            set { SetProperty(ref currentPosition, value); }
        }
    }
     

I am calling the write method like this

Code:

     clientMapper.Write();

What the mistake here? Did I miss any Attribute? The write method should write all mappings, or shouldn't it?

best regards
