read/write bitmap

[marcokrauss]

Hello,

how can i read/write a bitmap? I have created a variable with type ImageBMP in the model. The read function on the opc ua server looks correct (the value is filled). But on the client the value in the DataChange item is always empty.
I use the c# sdk. Can somebody help me please?

Hello marcokrauss,

this sounds like you are implementing client and server. For that scenario it's always a good idea to test one side with a product that's known to work.
We have sample variables in our DemoServers (Objects->Demo->Images) you can use for testing your client.
UaExpert provides an ImageViewer plugin you can use to test your server implementation.
As a first step use these to find out if you have a problem on the client side or on the server side.
