Hello.

If the post was about RegisterNodes/UnregisterNodes OPC UA services: We have a prerelease version of this feature in QuickOPC now. Reply here if you are interested.

Hello,

such functions do not appear anywhere in OPC specifications, as far as I know, so it looks like something Siemens specific.

It remotely resembles the RegisterNodes and UnregisterNodes services in OPC UA, maybe that's what they wanted to say. If you want to learn more about these, download Part 4 of OPC UA spec from www.opcfoundation.org.

Best regards

hello

I'm planning to do an integration with the built in opc server in the Siemens CPU 1516-3
So i'm reading the manual, "S7-1500, ET 200MP, ET 200SP, ET 200AL, ET 200pro Communication"
it says "..
If you access specific tags regularly (recurring access), you should use the functions "RegisteredRead" and "RegisteredWrite"
.."
Has any a clue what it means?
Thanks for any suggestion
Regards
Greg
