I all, I'm writing a node-red code with s7comm node. I would like pass the signal and path message from a injection instead of set it in the "connection parameter"

this because I would create a general code with could work with many machines instead of customize parameters for each machine.

can someone help me?

Hi,

Unfortunately, it is not possible to set the connection parameters from a message because the node you are using is not supporting it.

There is a workaround which involves the use of the [Admin API](https://nodered.org/docs/api/admin/methods/) directly from node-red to dynamically change the connection parameters of the node.
