Hello, I would further investigate why the OPC soltion failed. For Windows 7, be sure you you have used at least version 8.x of Simatic Net (or the latest V12). Before writing your own code, test with the OPC Scout (which is an OPC Client part of Simatic Net CD). This would confirm the correct installation of the server. The getting started can be found here: http://support.automation.siemens.com/WW/view/en/77377601 Chapter 3.2 shows an OPC example for Profibus. Once you can access via OPC Scout, several examples are documented here: http://support.automation.siemens.com/WW/view/en/21447513 |

Hello dimitri; What model of control unit do you have for the rectifiers, and do they support a Profibus-DP interface? I found this page on the web, for example, for one of PE units that interfaces with Profibus-DP:: http://www.plating.de/en/metanavigation/news/newsleser/items/New_compact_Power_Supply_Series_POWER_STATION_pe4606_pe4606-2.html Once you have idenntified the model, you must find its "gsd file", which is a text file that contains all basic parameters for a Profibus-DP slave communications, this file is provided by the manufacturer of the unit. So you must search on their website or contact them to obtain this file. Once you have it, you must integrate it inside the Profibus configuration software of the DP-master. In case of a Siemens S7 PLC, that would be the HWConfig editor. Open the HWConfig, close existing configurations (there must be no opened files), click on the Tool menu and "InsertGSD file". When you open your configuration the slave will appear in one of the directories of the Profibus configurator. Hope this helps, Daniel Chartier |

Hello dimitri; The help I can provide in Visual C++ is very limited. Hpowever, i think that the following document could be of help: SIMATIC NET DP Base Programming Interface for CP 5613 Hope this helps, Daniel Chartier |
