HI Mikko,

I am trying to convert string value to GXTime.

In that got

GXTime gXTime = new GXTime("07:00:00");

String '07:00:00' was not recognized as a valid DateTime.

Can you please provide update in c#. As I have to convert multiple entries.

Hello,
I want to read an energy meter using its RS232 port with GXDLMS Director.

The meter I am using is L&T EM101+ DLMS Cat C3 IS15959.

I do not have a RS232-to-USB cable with a DB9 connector right now. I have a MAX3232 RS232-to-TTL converter and an FT232RL USB-to-TTL module.

My idea is:
Meter (RS232) → MAX3232 → TTL → FT232RL → USB → GXDLMS Director

Will this work?
Can I convert RS232 to TTL using the MAX3232, then convert TTL to USB using the FT232RL, and read the meter normally with GXDLMS Director?

Hi, I am newbie with DLMS. I am testing Gurux.DLMS.Python and I am working with a meter simulation software. I am able to use the Gurux.DLMS.Client.Example.python giving the command "main.py -S /dev/ttyS0 -c 16 -s 1 -a None" and the simulator works fine. When I sniff the frames, at first step the python code send the SNRM frame:

7e 0a 07 03 21 93 0f 01 7e

the simulator answers with UA response

7e a0 20 21 03 73 73 98 81 80 14 05 02 00 80 06 02 00 80 07 04 00 00 00 01 08 04 00 00 00 01 ce 6a 7e

Hello Mikko,

What should I do to get method call result?
For example, object target is of GXDLMSImageTransfer type.

Let's use method 3 "image verify".
As written in BlueBook "The result of the invocation of this method may be success, temporary_failure or other_reason."

Following code works ok:
reader.readDataBlock( target.imageVerify(reader.client), reply)
How should I check that result is success, temporay failure or something else?

Is it reply.error values according to green book or something else?

Hello Sir,
I am using below dependency in my Android project. But when I ran my project with minSDK version 29 its gives error so, to using those I need to maintain my minSDK version 31. Is it possible to run in 29?

Hi everyone,

I’m trying to interface a Schneider Electric / L&T DLMS Category C3 bi-directional energy meter using its RS232 port, which is exposed using an RJ11 4-pin connector. I’m stuck at a few points and would really appreciate guidance.

1. RJ11 RS232 Pinout (4-pin) for L&T / Schneider meter

The meter manual is not clear on the RS232 pinout.
Does anyone know the exact mapping for:

Pin 1 – ?

Pin 2 – ?

Pin 3 – ? (ground?)

Pin 4 – ?

A confirmed TX, RX, GND assignment would help a lot.

2. No voltage on pins?

Hello Mikko,

I have Data class object where attribute 2 is of Structure type, for example.

<Structure>
<UInt8 Value="255" />
<UInt8 Value="255" />
</Structure>

I need to write new value for this attribute.

This sample gives me python type error (something like 'type not set'):

Hi,
How can I set counter number with number only like GuruxDLMSDirector without obis code. I'm using gurux DLMS.Python.client
