Re: [4diac-dev] Creating OPC UA nodes with reliable ID

[Stefan Profanter <profanter@xxxxxxxxxxx>]

Hi Jens,

unfortunately that's currently not possible in 4diac.

It is on our TODO list to refactor the way nodes are created, i.e. more intuitive browse path defintion.

For now you can use the "TranslateBrowsePathToNodeId" method from any client to get the node ID for a specific FB (the browse path should always be the same).

With the refactoring we maybe find a way to also intuitively define node IDs for the corresponding nodes.

Subject: [4diac-dev] Creating OPC UA nodes with reliable ID

Hi,

from what I have seen OPC UA node IDs are created with numeric IDs. However those ID are unstable when modifying the program.

Is is possible to assign an OPC UA node a static ID when using the PUBLISH/SUBSCRIBE blocks?

Cheers

Jens
