Hello!

After updating the GURUX library for C#, an exception is thrown: "Image block size is bigger than max PDU size."This happens in the second step: "Initiate the Image transfer process". What could be the solution?

Hi,

Hi,

When you read image block size it's bigger than max PDU size.
From the Blue Book: ImageBlockSize shall not exceed the ServerMaxReceivePduSize negotiated.

Contact your meter vendor and ask them to fix this. Image block size is a property of the server and it's usually read-only.

BR,
Mikko
