I want to replace the number 6100 with a value stored in global context. Is is possible to accses this value inside this field with some kind of pointer like the enviroment variables use $?

What is the full name of the node? i.e. node-red-contrib-somethinng

Have you looked at eh documentation for the node to see if you can change it dynamically?

If it is a contrib node, I would go to the Flow tab here on the forum, look up the node, go to it's GitHub page and ask the author of the node.

I'd also take note of how long it has been since it was last updated.
