  2. Unable To Read Parameter Values From Landis+Gyr E550 Meter Using GXDLMSDirector - NoAccess Status

Unable to read parameter values from Landis+Gyr E550 meter using GXDLMSDirector - NoAccess status

DLMSDirector

Hi everyone,

I'm using GXDLMSDirector to connect to a Landis+Gyr E550 meter. The connection is established successfully, and I can read the basic DLMS/OBIS object structure.

However, I'm facing an issue when trying to read the actual parameter values - most attributes return a NoAccess status. As a result, I can't retrieve the data.

I've attempted to switch the authentication level to Low and High, using the commonly known passwords 00000000 and 12345678, but access to these attributes remains blocked.

Has anyone encountered this with the Landis+Gyr E550 meter?

Any help or suggestions would be greatly appreciated. Thanks!

Hi,

Did you refresh the association view after you connected with Low or High authentication? You must do it by selecting "File" and "Refresh".

This button is inactive because I cannot connect to the meter in Low or High mode. I can only connect in None mode.

Hi,

You can only read values without authentication. Have you tried to connect with Authentication level: "Management Access" or "Data Collection"?

The correct password should be on the meter documentation. If you don't own the meter, it might be changed.

BR,
Mikko
