Once the full reply is received parse it with ParseAAREResponse method.

If password is defined all data do not necessary do not fit to one message. So make sure these are set to correct values. The packet can be generated with AARQRequest method and it uses UseLogicalName and Authentication properties This command tells the device if authentication is used and whether Long Name or Short Name reference is used. This is the first command that is mandatory for all connections and device types. Set configure GXCOSEM Component with correct settings. Once the full reply data is received call ParseUAResponse method to
If the device does not reply to this message usually Server address is wrong or meter do not support DLMS. This handshake uses SNMR request to gather packet and window size information from the device. If IEC62056-21 handshake is used it is done before this.
#Dlms meter reading software serial#
This is done only with serial and modem connections.ĭirect tcp/ip doesn't need this. Some devices require IEC62056-21 protocol handshake when serial port connecion is usedīefore starting to communicate using DLMS protocol. The connection initialization depends on the connection type and the device. #Is used HDLC or COSEM transport layers for IPv4 networks (IEC 62056-47)Ĭlient.interfaceType = InterfaceType.HDLC #Is used Logican Name or Short Name referencing. Gurux DLMS components supports six different authentication level: Without authentication (None) only read is allowed. When authentication (Access security) is used server(meter) can allow different rights to the client. If Client address is wrong you will get authentication error. If Server address is wrong meter does not send response. Some manufacturers might use own custom Server and Client addresses. You can read here to find out how Client and Server addresses are counted. If authentication is used Client address changes. Usually you can use 1 as Server address and 16 as Client address when authentication is not used. Read basic information from Gurux.DLMS component before you start to create DLMS client.īefore use the following device parameters must be set.
