Salve,
se le
può essere utile le mando gli indirizzi di alcuni siti che propongono
toolkit per realizzare OPC server e client. Naturalmente lavorano in Linux
standard, non real time, ma sono utili per studiarne
l'implementazione.

Technosoftware (http://www.technosoftware.com
<http://www.technosoftware.com> ) has an OPC client/server kit for Linux, based on SoftwareAG's EntireX's DCOM implementation. Not sure if EntireX will port their stuff to something other than Linux. Intrinsyc (www.intrinsyc.com <http://www.intrinsyc.com> ) has a product called J-Integra, which supposedly bridges Java and DCOM (and therefore OPC), they also have deviceOPC, which is ported to (you guessed it) Linux. Kratzer Automation's web page (http://www.kratzer-automation.de/_private/inhalte/c0/c0_02_opc.htm <http://www.kratzer-automation.de/_private/inhalte/c0/c0_02_opc.htm> ) says (in german) that they have a OPC/Unix connector for Linux, Solaris and QNX, but I haven't talked to them as to availability. Contact Software AG about their EntireX product
(http://www.softwareag.com/entireX/). They have an implementation of DCOM for major flavors of Unix. (If you were using Linux, you could download it for free, but without source).
