Hi,

There is no built in interface to libnodave in Proview, and I'm not familiar with libnodave, but I can give you a hint on how to proceed.

You write an application program that handles the communication to the Siemens system via libnodave and attaches the Proview database with the gdh API. Create a bunch of Av, Dv and Iv objects to store the data from the Siemens system, and use for example gdh_RefObjectInfo to get pointers to the ActualValue attributes in the application.

You can read more about applications in Designer's Guide, chapter Application Programming, and about the gdh API in Programmer's Reference Manual.

Hello

Not by Profibus, but anyway.
I have a test system based on Proview 4.5 which communicates with a S7-300 using a custom driver based on 'libnodave'. It uses ethernet and native S7-communication to poll data from the PLC. On the PLC side we use standard ethernet module (the Lean model).
I hope to upgrade to Proview 4.6 soon and also go into production mode.
Libnodave is also GPL/LGPL licensed and I have no objections to share my code either.

Regards / Jyrki

I was looking for a kind of scada software to supervise a Siemens PLC.
This custom driver sounds as music in my ears.
So, if You are willing to share this driver with us, I would be very grateful.

Kind regards,

Frans.
