writing Error "Service not allowed"

Forums
Gurux.DLMS

We are writing Passive TOU day profile which have 4 day table and 8 rate in each table, when we write all 4 day table with 8 rate in all table and it start transfer success for 2-3 packet and post this next command failed and getting error "Service Not Allowed", but when we reduce the data means select only few rate in all table so getting all success.
We analyse that if Payload size is <512 Byte able to write successfully in block transfer, but if no. of payload >512 byte this scenario regenerated using library as well as DLMS director.

High GMAC meters can’t authenticate – can’t read invocation counter

Forums
General discussion

Hi all,

We have ~500 ameter300 DLMS meters deployed across the country. They all use the same key material (system title 5753450000000001, client title 434C4E5400000001, auth key D0…DF, block key 00…0F, GMAC password 0x3333…). The legacy OPC client (C# / MyDaAddressSpaceDevice) talks to them just fine, but it hardcodes Ciphering.InvocationCounter = 1.

6-digit field values from meter not fully received (only 5 digits shown)

Forums
DLMSDirector

Hello Gurux Team,

We are currently facing an issue while reading meter data using Gurux DLMS libraries.

In the field, some meters are configured to return values with 6 digits (for example, energy or billing-related parameters). However, while reading these values through Gurux, we are consistently receiving only 5 digits, even though the meter display shows 6 digits.

Observations:

The meter display clearly shows a 6-digit value.

Gurux response contains only 5 digits for the same OBIS/field.

I would like to know whether the Gurux DLMS supports AMR for bidirectional meters used in SRTPV applications. Any guidance would be appreciated.
