Applying Scalers

Forums
DLMSDirector

Hi

I want to Know while reading data from meter do we need to apply the scalers to the meter data separately or else gurux will automatically apply scalers to the meter data.

Please clarify this doubt.

Thanks

How to add objects manually?

Forums
DLMSDirector

I am using a Holley DTS545 smart meter. How can I add objects manually with OBIS codes? And how can I know it's working?
I attached OBIS codes of my meter's objects.

I am trying to connect to a Sagemcom T-210D using Suite 1 (AuthenticatedEncryption) and HLS-5 (HighGMAC).

Special days table modification

Forums
DLMSDirector

Hello Mikko,

As written in blue book 4.5.4 Special days table, methods insert/delete are optional. Gurux DLMS Director Add/Remove buttons in special days table objects unavailable for selection if methods insert/delete are not realized by meter manufacturer.

Is it possible to add Director functionality to modify Special Days table via ordinary set/get request?

Best regards, Andrew

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

Forums
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.

Forums
DLMSDirector

Hello Mikko,

There is a a small bug in recent Director functionality, though I can't recognize is it a code problem or a directive trouble (#if !NET5_0_OR_GREATER || WINDOWS_UWP)

I'm working with Activity Calendar object, Passive calendar tab, Day profile tab.
While trying to add day profile action with a start time field "00:00:00", I'v got a message that string is not recongized as a valid DateTime Value.

GXDLMS Simulator – AssociationLogicalName Not Listed

Forums
DLMSDirector

Hello everyone,

I'm working on a tool to virtualize a low-voltage TLSBT meter using the Gurux.DLMS.Net simulator. I cloned the real device using GXDLMSDirector and generated a valid XML file, which I load into my simulator using the official GXDLMSMeter.cs class.

My goal is to replicate the behavior of the real meter, where, upon connecting with ClientAddress = 1, I can see multiple GXDLMSAssociationLogicalName objects listed:
