A friend has asked if I could implement a data historian. I am busy doing research, googling around, reading UPC Unified Architecture – but it’s a lot to get through, so I will ask if anyone here has ever gone down that road (while still continuing my research).
Approx how many man months for a 20+ year developer (or two) to get at least a demonstrable working prototype – and how long to completion?
Which programming language? Is C++ good, or what?
What resources are available to me? (I thought I saw an Open OPC framework, but can’t find it again). Any FOSS, libraries or free code which I can base upon? Maybe a sourceForge project?
How best to test?
Any other hints?
It would be interesting if you can do a write up of your project when you complete it.
For OPC libraries your pretty limited, but OPC Connect has a good list of UA development kits otherwise you’ll need to be a corporate member with the OPC Foundation.
