Hi.
I am beginner in dlms protocol. i want to communicate with HXF300 electrical meter. I perform application association successfully but i have problem in getting objects:

I have sent the following hex frame for reading clock:
// 7e a0 19 03 21 32 6f d8 e6 e6 00 c0 01 81 00 08 00 00 01 00 00 ff 02 00 65 d7 7e
meter responds with:
// 7e a0 11 21 03 52 b1 f8 e6 e7 00 c4 01 01 01 0b a1 04 7e

and I have sent the following hex frame for reading L1 voltage:
// 7e a0 19 03 21 76 4f dc e6 e6 00 c0 01 c1 00 03 01 01 1f 07 00 ff 02 00 09 e6 7e
meter responds with:
// 7e a0 11 21 03 96 99 78 e6 e7 00 c4 01 01 01 04 56 fc 7e

I dont know what error happens.
can you tell me what is the meaning of "01 01 0b" in 1st response. and "01 01 04" in 2nd one.
 

Hi,

"01 01 0b" in 1st response means "scope of access violated error" and "01 01 04" means "object undefined error"

Perhaps these objects which you are trying to read is not available in the association and you need to associate with a different client ID

Best regards, Balu, Kalkitech.
