I am trying to connect Holley DLMS meter with low authentication when i connect it after some time it gave me the error i think i get these while reading profiles or somting

(Gurux.DLMS.GXDLMSException: Access Error : Device reports Read-Write denied.)

After this when i try to read the data after a while on read it gave me this error.

(system.argumentoutofrangeexception: valid values are between 0 and 999, inclusive. parameter name: millisecond)

Both error logs are below :

Error 1 logs on connection :

While working with the meter I want to get information about invocation counter and server behavior.

1. What could be the behavior of server if we send the connection request in wrapper interface with different invocation counter value which server device have. Is server should respond with error or the communication continues?
2. Is there any condition when client is sending the request but server will not respond? ? If No is it mandatory that server should respond with some status code or success data?

Dear Mikko,

I want to read specific meter objects in one go.
Is it possible to read from GXDLMSDirector tool ?

It's possible in DLMSDirector convert octet value to readable string?

Thanks
Marco

hi, I have connected erp300 L&T dlms meter via serial com....But I got only manufacture's data and clock data only....I didn't got any data about voltage, current, kwh reading.etc.....i hope you will reply soon..screenshot is attached below...

Hello there.

I have been using the GXDLMS app to communicate with a data logger I have been developing.

After recent update, I am unable to use two classes - LTE Monitoring and Push Setup. Below I have included the specific errors received when trying to interact with these

I have tried to communicate with rs232 ....but no reply from device.......cables are good it tested with loopback test....meter have rj11 port and pins are 1.Gnd 2. Rx 3. Tx 4.RTS

Sir,

We are generating cipher text and authentication tag using openssl ,our sample encryption code and gurux dlms director (AES GCM 128).
We are getting the same cipher text and authentication tag from both our sample code and openSSl codes, but when compared with gurux dlms director
it is not the same, because of this we are unable to move forward in meter reading.
Please find the below attached text file for your reference.

Hello there.

I am currently in the process of implementing DLMS protocol on a data logger. Because there have been some issues with the end user mixing up some of the objects I have decided to create the manufacturer settings on the DLMSDirector ( version 9.0.2311.1001) for my company.

I am getting Failed to receive reply from the device in given time. when i am trying to connect with com-port and and getting Connection is permanently rejected. Authentication failure. on HDLC Address resolver . i am stuck and unable to connect please help .
