Hi,

Check the client example it reads all values from the meter. Check com_readProfileGenericColumns and com_readProfileGenerics methods. They do what you want to do.

Hi,

You are using logical name 0.0.40.0.0.249 when it should be 0.0.40.0.0.255.
Try to change that.

Hi,

You need to send cl_getApplicationAssociationRequest when you are using High level authentication. If you don't sent it meter don't allow you to read anything. Check that you are sending it.

hi sir

hi sir
yes i am sending cl_getApplicationAssociationRequest under com_initialzeconnection function

Hi sir,

Hi sir,
when i exicuiting assosiation view function i return an error with 269 value
and also i am getting 590 and somtimes i am getting 1400 bytes responce.

Hi,

Can you read the meter with GXDLMSDirector? You should get the same amount of bytes in the response if you are reading the same authentication view. Your authentication view might be differents when you are using different authentication levels.
