how to pick up PROFINET data and store them to OPC UA server on Node-RED/netPI.

[tad]

Hello everyone,

I am now trying to access the netPI from a windows PC via OPC UA.
Because my OPC UA client on the windows PC wants to access PROFINET data via OPC UA.
That means the netPI is used as an edge computing.
But, I don't know what kinds of Node-RED nodes I should use and how to configure nodes at all.

Current hardware components:
Siemens S7-1500 PLC  <==PROFINET==>  netPI  <==OPC UA==> Windows PC (uaExpert)
(netPI: NIOT-E-NPI3-51-EN-RE)

Current situation:
- The following dockers have been already deployed.
  hilschernetpi / netpi-opcua-server 
  hilschernetpi / netpi-nodered
- opcua nodes such as 'opcua server', 'opcua event' etc. are also shown on the left side on Node-RED.
- PROFINET data is exchanged btw S7-1500 and netPI properly.
- An XML file (OPC UA nodeset) was compiled and loaded into netPI properly.

Actually, I would like to know how to pick up PROFINET data and store them to OPC UA server on Node-RED/netPI.

Thank you very much for your kind advice.
Best regards,
