Hi,
I have tried run DLMSServerExample and have read its objects with DLMS Director. When I have read the whole group of objects, for example Registers, everything has worked correctly. But if I have read only single object (with right click on object and select Read option or Read object option), this exception on DLMSServerExample server occurs:
Exception: read access violation.
**_Pnext** – 0xDDDDDDE1.

I have tried read the objects with my own client, which uses the Gurux library. If I have read single register everything has worked correctly. I have tried to decode the messages which are sent from my client and from DLMS Director. The difference is that my client send request to the server for each attribute of object separately, but DLMS Director send one request which contains all attributes (multiple references service). The DLMS Director uses this service (send same message) also if I unchecked it in Device Properties -> Supported Services.
Note: This problem occurs only with LN referencing.
I don't know how to create the server to support the multiple references service.
Thank you in advance for your answer.
Hi,
Hi,
Maybe it's the object that you try to read.
What compiler you are using? I just checked this and it works without problems, so I need more info.

Hi,
Hi,
I have simply downloaded the source code from https://github.com/Gurux/Gurux.DLMS.cpp. Then I have built it with VS Community 2019 and have ran the GuruxDLMSServerExample. I didn't add any of my code.
After that I add new device to the DLMS Director. You can see the configuration of DLMS Director on the screenshot below.
The reading works on Data objects and doesn't work (the exception which I described above occurs) for example on Clock, Register, IecHdlcSetup and Security Setup objects.
Thank you so much.

Got the same bug while read
Got the same bug while read profile generic on ServerExample, old version of GuruxCGXDLMSDirector reads data normaly, and new version sends incorrect request to server or server unable correct handle request data, such as m_RowToPdu and m_Selector always equal 0.
On old version same request
On old version same request of same profile generic on same ServerExample.
Hi,
Hi,
Please, don't add images. They are hard to read. When you are reading profile generic do you try to read with "Read by Entry", "Read by Range" or "Read All"?
