Hello,
I am trying to read data (and "clone") from Sanxing device ( https://www.dlms.com/product/SX5A2-SELS-04_140 ) using network (also I have tried serial line) with no success.

I have executed (using java build of simulator):

java -jar simulatorBuild.jar -h 192.168.133.12 -p 8088 -o sanxing_template.xml -t Verbose -w

Resulting into:

TX: (simulator with params "-h ipaddress -p 8088 -o template.xml -t Verbose -w" to sanxing device)
000100100001001F601DA109060760857405080101BE10040E01000000065F1F0400001E1DFFFF

RX: (from device to simulator)
000100010010002B6129A109060760857405080101A203020100A305A103020100BE10040E0800065F1F040000101D01E80007

TX:
000100100001000D0C01C1000F0000280000FF0200

RX:
0001000100100003C402C1

Disconnect request

TX:
00010010000100056203800100

RX:
000100010010000D630B800100BE0604040E01FFFF

Using your online decoder ( http://www.gurux.fi/GuruxDLMSTranslator ) I have found that connection was done correctly, but reading have somehow failed (online decoder is not able to decode second request and second response).

I have attached also screenshot when reading using serial line. Note, that default application from manufacturer does have set "Mode E" instead of DLMS when reading through serial line.
Any advices how to read data and make given device "virtual" (using simulator)?

Hi,

For serial line communication, one of your settings is different than meter expects.
If you are using an optical probe you need to add -i to move mode E. I believe that is the reason why meter doesn't reply.

It's interesting that the meter is not certificated using WRAPPER, only with HDLC.

I believe there is a type in your message. You have written that it's

00 01 00 10 00 01 00 0D 0C 01 C1 00 0F 00 00 28 00 00 FF 02 00
when it should be:
00 01 00 10 00 01 00 0D C0 01 C1 00 0F 00 00 28 00 00 FF 02 00

Try to read using the serial port.

BR,
Mikko

Thanks for tip with "-i" parameter. I will try it.

An you are right, I have typo in given packet. I am appending screen just for info.

Hello, IEC reading start does not help. We have tried with "-i" and also "-i -w" parameters. See screenshot. Copy/paste ready data are here:

Any other suggestions?

PS: Actually my goal is to make "virtual" sanxing device using simulator (or using GXDLMSSecureServer2 class for example by hand).

Hi,

Can you read your meter with GXDLMSDirector? Data seems to be correct.

BR,

I try to use GXDLMSDirector. Now I have working example using other sw. It seems that given sw is reconnecting to serial line...

Reading register (using other sw) 0.96.1.0.255 and sniffing on serial line:

A bit nicer formatting (joined lines and removed ascii):

tx -> sw writes to serial line; rx -> sw is receiving data from serial line.

Hi,

Your meter is using different server address. Try with parameters:
-i -s 28672

Hi,

Data bytes are correct. I checked from your logs that other application doesn't wait after moving to Mode E.
It's interesting because the delay is in the standard.

Try to remove Thread.sleep. Find // This sleep make sure that all meters can be read.
end then remove two Thread.sleeps.

BR,
Mikko

Thanks for suggestion. I will try.
PS: Using GXDLMSDirector have failed with "Invalid response" info. Perhaps serial line stayed open and restarting director was the only option to make another test. Invalid response was perhaps due manufacturer information doe not met selected (Hexing) one.
PS2: Reading data using Net (using GXDLMSDirector) has not been tested, because the only windows which does have network connectivity to smartmeter, does not have connectivity to Internet. Is there any installation procedure for such PCs?
