Hi,
I am trying to read L&T meter using Gurux Java library. I am able to read all the values except load survey.
While reading i am getting the below error.

readRowsByEntry = Error! Failed to read first row: Access Error : Device reports Read-Write denied.
readRowsByRange = Error! Failed to read last dayAccess Error : Device reports Read-Write denied.

What might be the problem for this type of error ?
How to fix this ?

Hello everyone,

Sorry for my ignorance but I am new to Gurux. I am trying to read from meter using Gurux component over TCP. I have all required information to do so. I used Gurux Director to successfully read the data, but I have really hard time reproducing what Gurux Director does into Java code. I am trying to combine gurux.dlms.java with gurux.net.java but I cannot find the connection.
Can anyone could point me to the right direction?

Thanks

Hello,
I work on a smart meter simulator and I have trouble with the DLMS representation of GXDateTime when daylight saving is active. When I initialzie GXDateTime with the date 2017/03/26 03:00:00 CEST, the binary representation is the following
09 0C 07 E1 03 1A 07 01 00 00 00 00 78 80
It is wrong, because the time set to GXDateTime was 03:00, but the binary form contains 01. The sources of gurux.dlms.internal.GXCommon show that 1 hour is always deducted when daylight saving is active.

Hello,

I'am developing MDAS(meter data acquisition system ) in java. I want the standard DLMS METERS protocol sheets so that i can convert the data.

At present I'am only able to convert the Instantaneous Data of different make meters like(DLMS SECURE, DLMS LNT meters) .

My major requirement is to convert Complete data coming from the meters.
Complete Data consists of D2, D3,D4,D5,D6 according to MIOS.

Any one having the documents for converting DLMS secure & DLMS LNT meters data, please mail me the document.

Thanks in Advance

Hello guys.

I'm trying to establish a connection with a meter using GCM (Authentication and Encryption).
AK and EK are all zeros (16 bytes 0x00), System title is "48 45 43 00 05 00 00 01".
Using the manufacturer software I'm able to communicate.
The problem happens in the "parseAareResponse" method, where I get a "invalid tag 97".

Hi,

I'm working on a cosem object which must return data in a COMPACT ARRAY.
The problem is in GXCommon.setData() :
switch (type) {
...
case COMPACT_ARRAY:
throw new RuntimeException("Invalid data type.");

Why is COMPACT_ARRAY type not possible ?

Thanks
Mansour.

Hi,

Thanks in advance.

HI,

I have to implement a COSEM objet of type "S-FSK Phy&MAC set-up" (class_id: 50) using Gurux.dlms java lib and I have noticed that this type doesn't exist in gurux.dlms.enums.ObjectType.

Can you please tell me how to implement this in an other way than extending GXDLMSObject and implementing all the logic ?

Reference : Bluebook 11th edition §4.9.3

Thanks
Mansour.

Hi,

Hi, I'm a beginner in DLMS/COSEM and I'm using last version gurux.dlms.
I have problems when I call a parseUAResponse method.
I send a SNRM request: 7E A0 07 03 03 93 8C 11 7E
and I receive: 7E A0 20 03 03 73 F0 2E 81 80 14 05 02 01 00 06 02 01 00 07 04 00 00 00 01 08 04 00 00 00 01 69 6D 7E
