Limitations of live mappings?

Hello:
Yes-subscribe to the update failure event
Not precisely. Not a separate class. Just pick one of the properties that do not update, and add an extra property to the same class, next to it. E.g. besides having "public double Input1 { get; set; }, add also "public Exception Input1Exception { get; set; }". And use "[UAData(Kind = UADataMappingKind.Exception)]" as you have in your example. BUT, everything else (attribute-wise) should be the same as on the original property. So if your original property for subscriptions and reads, the exception one should be too - so that you can diagnose the subscription/read issues.-mapping the a similiar class with a different mapping kind (exception, error code, etc.) to the struct on the server where the data type should match the mapping kind?

Just for clarification, my next steps should be:
-subscribe to the update failure event
-mapping the a similiar class with a different mapping kind (exception, error code, etc.) to the struct on the server where the data type should match the mapping kind? --> do you have an example for this?
Do you mean something like this?

Code:
[UANode, UAData(Operations = UADataMappingOperations.Write, Kind = UADataMappingKind.Exception)] // not readable
public Exception Input1 { get; set; }

There is no such limitation in the Live Mapping.
First thing to do in the troubleshooting is to make sure you have all information about possible errors that might be occurring. Please read "Error Handling in the Mapper Object": opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...n%20the%20Mapper%20Object.html .
Make sure you have some way to detect all these kinds of errors. Specifically, make sure you also add some mapping with Kind of Exception (or ErrorMessage or ErrorCode) ( opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...rame.html#Mapping%20Kinds.html ), so that you can discover the issues described under letter (D). But other possible causes, e.g. (C), cannot be ruled out either, so please have some handling for them too.

Limitations of live mappings? was created by Captain_Dash
Hello,
I tried to use the live mapping feature for struct on the opc server. I created a class which is similiar to the struct and equipped the class with the attributes of your live mapping feature. Of this class I created 3 instances because I need to map each class to a different instance of the struct on the server. In the first place I started to map this class and everything works fine, so added the second, still everything is fine. I am getting the changes from the server, so the subscription is working, i call the read method and all values are read. But if I add the 3rd instance nothing is working anymore, neither the subscription nor the reading of the values. If I only run the 3rd instance alone everything is working again.
Why is this happening? Are there any limitations in the count of the mappings?
