Using localhost on OPC UA endpoint configuration Node

General
1

Hi,

I am new to Node-Red, In my Project I have a Codesys and Node-Red and both of them running in single Raspberry Pi OS.
I am having a OPC-UA as a communication between these two application and Codesys acts as a server and Node-Red is one of the Client.
I am sharing nearly 1000 variables between them, On the OPUA Endpoint configuration node ,

  1. Is it ok to use opc.tcp://localhost:4840 instead of opc.tcp://192.168.1.175:4840 ?

  2. While doing this., Will be there be a benefit of reducing the network traffic on the 192.x.x.x network ?

  3. While doing this , Will there be a chance of increasing of Raspberry Pi OS CPU Load ?

Your input highly appreciated.

Best Regards,
Mani
