The recommended netPI Node-RED version available as docker container is located here: https://hub.docker.com/repository/docker...pi-nodered. It includes of course Node-RED pre-installed, the PROFINET fieldbus node and the Azure nodes.
With PROFINET it is quite easy. In your PLC PROFINET engineering software you have to import the socalled GDSML file from the netPI fieldbus node first. Then you have to configure the number of process data inputs and outputs the netPI shall represent in the PROFINET cycle. In your case only outputs may be enough, since you want to output data from your PROFINET master to the netPI PROFINET device only. This configuration has to match to the number of inputs and outputs you configured in the netPI fieldbus also which is the second step.
The most important thing is that with PROFINET all devices are getting their IP address from the PROFINET master automatically. In order to let the master set the correct IP address for the respective device, the device needs to get a unique name in the network that is usually setup using the PLC engineering software with a special PROFINET command. All engineering software I know have implemted this function.
To get well informed about getting a Docker container to run on netPI watch this video first of all: https://youtu.be/A-asfhl7b0c. It shows how you make a basic setup of the netPI in general and to let it start the Docker engine and then how you deploy a Docker container in general afterwards.
If your PROFINET master is a Siemens PLC then I have another video https://youtu.be/2WBt8XAurVU that shows the overall procedure how to get netPI running with a Siemens PLC over PROFINET.
Thx
