Posted 6 Dec 2007 Hi All! Do anybody know about any free OPC server that can communicate with Siemens (or Mitubishi) witch is free? Would like to communicate with the OPC Server with Visaul Basic.Net Share this post Link to post Share on other sites
Posted 7 Dec 2007 Hi edda. For Siemens you might want to look at Libnodave. It is not OPC but it is free. http://libnodave.sourceforge.net/index.php Share this post Link to post Share on other sites
Posted 8 Dec 2007 I haven't run across any free OPC Servers. The free projects are usually APIs that are written in C. There are some .NET ones, but I don't know about Siemens or Mitsubishi. Share this post Link to post Share on other sites
Posted 12 Dec 2007 There are numerous free downloads here, but if you read closely, they're all licensed with limited user time. http://www.opcconnect.com/freesrv.php Share this post Link to post Share on other sites
Posted 14 Dec 2007 Thanks for the link - great info. I've dealt with many on that list and none are free. The DSxP simulator is, but I doubt that's what OP had in mind. Share this post Link to post Share on other sites
