Well on the project i have up and coming i have to send info and store data in so many ways Desk Top app, Web and eventually mobile devices!! And all has to be routed through an OPC Server.
After some research, learning and trial and error i am on the right path!!
I started with AHMI solution and added WCF and then just a console app. I am just starting to develop this but thought i would post some info in case anyone has some ideas or suggestions. When complete it will be able to connect what i call the black box to the OPC server and then from there i can request the data from and send data back from any platform!! This could be easily configured to communicate directly with PLC's but due to where i work the Process Engineers say i have to use the OPC so they can limit access primarily on writes so i am not dumping a ladle full of molten steel on someone, so i see there point
the screen shots i a attached are of the Matrikon OPC simulator. Any questions or comments please go for it!!
