Holley DTSD545S

Hi,

You need to change the interface from WRAPPER to HDLC.
If the meter is still not responding, check your serial port settings, as well as the logical and physical addresses. They should be described in the meter documentation.

Hi,

Try with a baud rate of 9600.

Logical address: 1
Physical address: 0x1C.

The settings vary between meter models.

Hi,

There is an issue with some Holley meters and you can't read the association view (object collection) from the meter.

You can ask if a firmware update is available for your meter that addresses this issue.

If you have a list of the objects, you can add them manually.
You can start with the clock object.

Select your meter and the select "Edit" and "Add object" from the top menu. Select clock as a COSEM object and press ok. You can now read your clock from the meter.

Hi,

Can you read the clock? Do that first to make sure that the reads work.

You didn't give the logical name for the object. That should be in the meter documentation.

You need to ask for the document from the meter vendor that contains all the objects you can read from the meter.

Hi,

I believe that you need to change the authentication level from None to Low. You must also change the client address. That should be in the meter documentation.

Hi,

Try to connect with public address first. You should be able to establish the connection to the meter and read values. Set the authentication level to None and the client address to 0x10. Those are the default values.

Then change the authentication level to Low or High and set the client address to 1, and set the correct password.

Hi,

Yes, you can use the Python client example to read your meter. You can see the command line arguments when you select the meter in GXDLMSDirector.
