Hi. I wish to try use Data Source Manager with CODESYS Symbolic data source.
I edit Device Description file of CODESYS Control Win V3 and add next lines:
Unless I'm mistaken, I'm pretty sure you will need to be online with the opc in order to see it.
On the PLC with the data source:
Set up the symbol config, compile it and make sure all the items you want are configured to share.
Then, on the device that will be the client, go online, connect the data source, and then all the items will be visible to add to your project. They will remain visible after you disconnect.
There might be other ways to do this, but this has worked for me.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I understand now!! thank you for clarifying.
I actually do not know. I had the same problem and ended up using the only
available option, codesys application instead.....
Then I bump this post to see if someone else may know how to get the
symbolic option to appear?
Yes, the CODESYS HMI is the only product in the CODESYS store which has the symbolic data sources feature and the license in its runtime. Maybe there is an OEM out there with this built in. I think the Data sources OPC UA Client is the way to go (as Edi mentioned).
I do not know the licensing exactly, but I think it will need to buy a OPC UA Client SL.

I edit Device Description file of CODESYS Control Win V3 and add next lines:
I save it, install in device repository and update device in my project.
But i still can't choose CODESYS Symbolic in Data Source Manager.
Have I made some mistake?

to do what?
With 3.5SP17 release you add DataSource - and configure the OPC UA CLient that way.
I need to read data from remote PLC with symbol configuration.
About SP17/DataSource/OPC UA client - will i have to buy a some license to use this?

I just want to understand how to use this option:

"As the data source type, select CODESYS Symbolic."
Please check screenshot from my first post and show me how can i choose CODESYS Symbolic.
Try with CODESYS HMI. Demo in the store.
So it's only CODESYS HMI feature and I can't use it for plc-to-plc communication?

Thank you for info.
