Can anyone tell me if OsiSoft OPC UA or DA connector/interface can talk to Beckhoff Twincat OPC server?
According to Beckhoff's site:
"TS6120 | TwinCAT OPC Server
The TwinCAT OPC Server is a standardised data exchange interface. It supports the DataAccess (DA) and XML-DA specifications. DataAccess (DA) is based on the Microsoft COM technology and provides data for the client. The OPC XML-DA specification enables data exchange through XML via HTTP. Configuration of the server is carried out in a configuration tool or via XML."
So yes - you can use OSIsoft's PI OPC DA interface to communicate with this server as long as it is configured for the DataAccess (DA) specification.
I see from Beckhoff's website that they also have an OPC UA Server. This could be communicated with via the PI OPC UA Interface.
Thanks a lot for your answers, I see now that I have to change the question.
Beckhoff has an OPC UA server.
OsiSoft has an OPC UA Connector, which is not tested at our site, BUT we have a lot of OsiSoft OPC DA interfaces feeding our PI system.
My question was actually ment to be : Can OsiSoft OPC UA Connector or OPC DA interface talk to Beckhoff OPC UA server?
Sorry for the confusion...
Hi Pal - no problem!
The OSIsoft OPC UA Connector will be able to communicate with the Beckhoff OPC UA Server.
Pal, is this a general query or have you tried it and failed to get a connection. If it is the latter then you may be getting caught out by the network infrastructure and Windows DCOM https://scadahacker.com/library/Documents/ICS_Protocols/OPC%20Training%20Inst%20-%20OPC-DCOM%20-%205%20Things%20You%20Ne…
If this is the case then you need to talk to your IT/OT network guys and you may need to include a Tunneller. I would also be an idea to check that the OPC Server service is running at the other end, easier said then done.
Sorry for late answer....
I have not tried it out, my question was simply to find out if they can talk together, and was an offspring from a vendor telling us they can deliver equipment
with Beckhoff OPC UA installed. We have a lot of OPC DA interfaces, but have not looked at OsiSofts OPC UA connector yet.
I can't speak for the compatibility between OSIsoft OPC UA and the TwinCat OPC Server as I have not tested that.
That being said, the OPC DA Interface will be able to grab information from the Beckoff Twincat OPC Server. The only requirement for this to work is that you'll need to install the TwinCat OPC Software. You'll have to contact Beckoff to get the software.
