Hi all,

we are wondering how to use the action REGISTER in the OPC UA Client node:

 ![2022-11-15_09-31-47](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/f/aff9f1ad11e4309278def0409123ca100cb74302.jpeg)

How is the syntax to register a NodeID (as payload or topic or how does it work)?  
An example would be highly appreciated 🙂

Thanks,  
Steffen
