Gurux.DLMS

Hello

I am doing a project for MSc in which, one part is to communicate a Siemens SCADA, which uses protocol PROFINET/MODBUS with two smart meters Landis&Gyr which use DLMS protocol. I know there are gateways to convert the protocols, but I am interested into making this with software. Can I do it with Gurux?
Hence, I want the SCADA being able to read the measurements autonomously (from smart meters) and take decisions. The connection at the moment is implemented over a lan with switch so all the devices are connected on the switch.

Cheers

Hi,

You can do this. You need to listen to PROFINET/MODBUS messages from the SCADA and then you can create a client that communicates with the meters. Modbus is quite an easy protocol. You need to save mapping between the MODBUS address and COSEM objects example to the XML.

Thank you for the reply. Is there a similar example to use it as a guide with something else or a a topic in forum that you may be aware.

Hi,

I don't believe that there is. We have made several DLMS to Modbus projects, where the client is operating with DLMS and meters are using ModBus, but not like you are planning. We have Modbus parser ready. I need to think if we can use it and make some kind of example, but it will take several weeks before we can start it.
