Tim and Ron,
Thanks for the response! I am aware of the OPC UA momentum, but haven't seen many practical implementations in direct controls.
If understand correctly, OPC UA isn't yet built into Proview, and will be a while before anyone (us, you guys, Claes) implements it.
I am currently trying to get students funded to do this sort of development, but we haven't had any takers yet.
Even so, I can see from Ron and your positions that OPC UA has enthusiastic support.
I'll add OPC UA to the long list of IO Protocols we'd like to see supported.
Ron,
Currently we are looking all over the world for our hardware, and certainly Europe.
To that end, we stumbled on this interesting little piece of kit:
Revolution Pi Industrial Hardware
Some points
1. Raspberry pi seems an ideal, long term hardware platform for remote IO. Standardized, open hardware and software. Honestly there is alot to like.
2. Software options, and lots of them. Run what you like.
3. RevPi Gate POWERLINK Slave AKA Powerlink support! We will be testing this in the near future.
I think I'd like to start a list of Raspberry pi hardware that might be OTS useful for industrial IO (and works with Proview).
Any interest?
I look forward to seeing the results of your project, too!
Thanks,
Matt
