I said I hoped I was wrong about PLC vendors not supporting integrated OPC-UA. That was in my last post and as it turns out, to some extent I was wrong, which is good. Matthias Damm pointed out that at least three PLC vendors are shipping with integrated OPC-UA interfaces, including Beckoff, Bosch Rexroth and B&R.
I did a little searching on Beckhoff, Bosch Rexroth and B&R to find out more about these controllers and found the Beckoff CX8091 controller right away but came away empty handed for the latter two. I'm hoping someone can help point me in the right direction on those two.
According to their website the Beckhoff controller is estimated for market release in the 2nd quarter of 2013. It is programmed using IEC 61131-3 languages and most importantly supports online programming changes. As you can see, they have the OPC-UA logo in the lower middle of their product.
Another poster pointed out that SAP and iTAC (who is iTAC anyway?) have already implemented OPC-UA. As I pointed out in my last post, it's not the software companies that are the problem. Most pure software companies have already adopted. It's the hardware companies that are lagging.
Kudos to the software companies who are now on-board, and kudos to Beckhoff for their new controller, but as I search the web for other hardware, particularly PLCs, with integrated OPC-UA, it is kind of spooky how empty the space is. So if Bosch Rexroth and B&R have it then why can't I find it with a web search? Are they just not promoting it? Someone please shed some light on this.
In my last post I pointed out three firms that provide SDKs for embedded OPC-UA. Matthias points out another provider is Unified Automation which provides a full range of OPC-UA SDKs and development tools for ANSI C, C++, Java and .NET.
All the tools are there, all that's missing is the motivation.
