Hi,
I try to use gurux java simulator to create some Landis+Gyr meters with almost the same specification as real meters using: https://github.com/Gurux/gurux.dlms.java/tree/master/gurux.dlms.simulat…
I would like to test if simulated meters are served correctly and if I can actually obtain data (registries, clock, readings etc.) in GXDLMSDirector. I will need it for integration and unit tests of my application.
I encountered 2 problems:
1. I cannot create meters with 'short name referencing', even if I see in console 'DLMS HDLC Short Name simulator start in ports 1000-1009.'
Simulator run parameters: -p 1000 -x mytestdevice.xml -t Info -N 10 -r sn
GXDLMSDirector command line parameters: -h 127.0.0.1 -p 1000 -r sn -n 55980097 -w 1 -f 128 -t Verbose
In GXDLMSDirector I see error: "Connection is permanently rejected. The application context name is not supported. Meter expects Logical Name referencing"
2. Negotiated conformance is only 'GET'. I would like to have also Read, Write, MultipleReferences, basically as much as I can, is it even possible?
Is it related to authentication level? Because it looks like I cannot make any other authentication than 'NONE' using GXDLMSDirector.
Any help will be really appreciated.
Best Regards,
Piotr
Hi, You need to read real…
Hi,
You need to read real Landis+Gyr meters that use short name referencing. You can't use short name referencing if your meter is using logical name referencing.

Thank you for the response,…
Thank you for the response,
So i have some real Landis+Gyr meters and I connect to those using short name referencing. In GXDLMSDirector I connect to this meter, right click on it and 'Read Object', then I 'Save values as' a MyMeter.xml file. Then i put this file simulator as a parameter together with '-r sn' so i expect short name referencing communication.
When I try to connect to simulated meter using GXDLMSDirector (or trying to call it in java code, doesn't matter) I see 'Meter expects Logical Name referencing'.
Below is what I got from the meter for GXDLMSAssociationShortName and GXDLMSAssociationLogicalName, I have no idea what am I missing here...

Please let me know if I can provide more details to help you understand the issue.

Hi,
You need to read your meter with the simulator and not GXDLMSDirector.
-c 16 -s 1 -h [Meter IP Address] -p [Meter Port No] -r sn -o meter-template.xml

Hi, Case 1: When I run…
Hi,
Case 1: When I run Simulator locally with run parameters: -p 1000 -x testdevice.xml -t Info -N 10
I am able to read meter with parameters: -c 16 -s 1 -h 127.0.0.1 -p 1000 -o testdevice2new.xml (so using logical name referencing)
It is ok.
Case 2: When I run Simulator with parameters: -p 1000 -x testdevice.xml -t Info -N 10 -r sn
Trying to read meter with parameters: -c 16 -s 1 -h 127.0.0.1 -p 1000 -o testdevice2new.xml -r sn (so using shortname referencing)
I see that Logical Name referencing is required anyway...
'The application context name is not supported. Meter expects Logical Name referencing.'
Log from the console:
Authentication: None
ClientAddress: 0x10
ServerAddress: 0x1
Standard: DLMS
DisconnectRequest
Connection is permanently rejected
The application context name is not supported. Meter expects Logical Name referencing.
gurux.dlms.GXDLMSException: Connection is permanently rejected
The application context name is not supported. Meter expects Logical Name referencing.

at com.kmd.hesmeterdatareader.dlms.simulator.Simulator.main(Simulator.java:266)
Can it potentially be a bug? Can it be a problem with my testdevice.xml configuration? (It would be weird because this is real meter to which I am able to connect in real world using short name referencing)

Hi,
I just want to bump my question from previous post just in case you missed it and I have another one.
Another question: Is it possible to have no security and have negotiated conformance with more methods than only "GET"?
I need at least "Read", "Write" and "MultipleReferences" is it doable with the simulator on any security level? I Cannot see any configuration in the code for meter conformance.
I will be grateful for any kind of help here.
Best Regards,
Piotr
