Hi Mikko,

I can establish communication with single phase meter in all associations and PC, MR in 3 phase meter. But when trying in US i am getting the following error. I have checked passwords and they are correct as everything is working in guruxdirector perfectly.

Hi,

Check your password. Are you reading the invocation counter with GXDLMSDirector? If you are, you need to add -V argument.

Hi Mikko,

I have used this command

python example.py -S COM11:9600:8None1 -c 48 -a High -v 0.0.43.1.0.255 -P VVVVVVVVVVVVVVVV -C AuthenticationEncryption -T 5641523030303031 -A 39393939393939393939393939393939 -B 39393939393939393939393939393939 -D 92288D3A30D12606F39ACC77B7C6832E -d India -w 1 -f 128 -t Verbose

It seems that I dont have much dependency with invocation counter. As i dont have any differene if i add it or remove it while reading. I have checked password again and it is correct as per the team.

Thanks

Hi,

Can you add the GXDLMSDirector log as a hex so I can check what argument is different?

Only the connection log is important. Please, don't all anything else.

Mikko

Hi Mikko,

The same settings are working as expected with single phase meter. Even i can download PC and MR with 3 phase meter. Not sure what additional changes that needs to done for US association. All the keys are correct and password is also correct as per the team. Can you confirm if there are additional settings that needs to be done?

Thanks

Hi,

The only thing that is different between GXDLMSDirector and your Python traces is the value of the invocation counter. Set the value of the invocation counter to one like this:

self.client.ciphering.invocationCounter = 1

Hi Mikko,

I have added invocation counter as suggested. But still the issue persists.

Hi Mikko,

I am using authentication key and Block cipher Key as 9999999999999999.

Hi,

Get the version 1.0.146. The default invocation counter value is changed from zero to one and ciphering invocation counter is increased in the same way as in C#. Let me know what happened.

Mikko
