Hi Walter,
well since your task is not very complicated my recommendation is to use the NIOT-E-NPI3-51-EN-RE device. It uses a netX51 Industrial Ethernet chip that enables you to operate as PROFINET slave/device with a max data amount of 1700 bytes inputs and 1700 bytes outputs just in case.
What we already have developed are two Node-RED (maybe you know Node-RED already, if not here a link for a short introduction https://nodered.org/) nodes that can be used directly to communicate with the netX51 chip. One node allow you to write data to the netX chip buffer which transports it to the master then and the other node reads data from the netX chip PROFINET buffer and injects it into the flow. And in Node-RED you have basically any possibility to handle this data quite easily. There is an example how to be a TCP client or server with Node-RED here https://flows.nodered.org/flow/bed6f676d...98943338b5. This in combination with the netX node will get you to the goal.
What you must know about the NIOT-E-NPI3-51-EN-RE device that it is a secured devices and does not allow to install any software natively under its Linux. You can only add own software to it using Docker containers. So the device comes preinstalled with Docker and on top you install your applications. We also have some example containers ready-to-use for the device ... and I mentioned Node-RED above ... and we have a Node-RED inclusive netX nodes ready to download at https://hub.docker.com/r/hilschernetpi/netpi-nodered. So you get installed Node-RED in about 10 minutes and from there you can then add your TCP based communications easily.
If you do not want to follow my proposal above using Node-RED you can also program the netX51 with C code that operates with a netX Linux driver to get it running. For that we have another container at https://registry.hub.docker.com/r/hilsch...-examples/ that shows you how to program the netX chip as PROFINET device, EtherCAT slave, EtherNet/IP slave, POWERLINK Slave or Modbus server.
Thx
