Which version of netPI do you use? I suppose you are using netPI CORE 3 (NIOT-E-NPI3-EN) with 1 single Ethernet port?
With option netPI RTE 3 (NIOT-E-NPI3-51-EN-RE) you have two additional ethernet ports. These two ethernet ports are usually used for Real-Time Ethernet communication in network such as PROIFINET, EtherNet/IP or EtherCAT. This feature is provided by the additional netX controller chip that is part of netPI RTE 3. This netX chip can also support standard TCP/IP.
But you need to program this Chip extra using a special Docker image https://hub.docker.com/r/hilschernetpi/n...hernet-lan. This Docker image transfers the netX chip into a standard LAN chip. But netX chip is slower on TCP/IP traffic than a normal LAN controller chip. So please read the README of the Docker image under the provided link for more details.
With WLAN I feel it is not always stable for long term communications. I would prefer cable based communications in all cases. The Wifi connection is more for service and maintenance for a short period of time.
Thx
