transfer data to another data element

[IKI]

Hello, I have such a task, I need to transfer data to another data element within one host. For example: A data element receives port 5000 from the text, and another data element needs to check the availability of this port - net.tcp.service[tcp,,5000], but it needs to be done through a change, since the port can change on different hosts. I tried to make a dependent data item and via key net.tcp.service[tcp,,{ITEM.LASTVALUE}] but this value returns the same port 5000. Is there any way to transfer the data? I have already implemented port reception, the whole problem now is to transfer it to another element. Is this even possible?

I think you should use discovery and item prototypes instead of dependent items.
