Hi

I have an HXE5\2HXF300 meter and I can connect but don´t read association view.

Negotiated:
BlockTransferWithGetOrRead, BlockTransferWithSetOrWrite, Get, Set, SelectiveAccess, EventNotification, Action

I try to read any objet (Ex: 0.0.1.0.0.255) without sucess.
Response is "Access Error: Read-write denied"

Command line with -v "0.0.1.0.0.255" return "Access Error : Device reports a undefined object."

Any idea?

Hi,

Some HXE meters don't implement the association view, even it is mandatory.
You can add objects manually by selecting "Edit" and "Add object".
The COSEM objects are described in the meter documentation.

Hi Mikko

I can read Clock (0.0.1.0.0.255) with Director setting Attributes Access to AuthenticatedReadWrite, but other OBIS codes

When i try command line:

py main.py -S COM8:300:7Even1 -i HdlcWithModeE -c 1 -a HighGMAC -C AuthenticationEncryption -T 0000670005000001 -A 00000000000000333435363738390000 -B 00000000000000033435363738390000 -w 1 -f 128 -t Verbose -v 0.0.1.0.0.255

The response is: "Access Error : Device reports Read-Write denied."

How to set AuthenticationReadWrite in command line?

Hi,

You can't. This is a meter specific issue and you need to modify the source code for your needs.
