Why do you need the complexity of a web server if you only need to harvest the data from some sensors and pass it on to another server?
Maybe MQTT (trivially easy to implement on an RPi running Raspbian) would be worth investigating?
If you feel more comfortable with GUI/visual tools, NodeRed might provide an acceptable way of interfacing the external devices. It can cooperate in an mqtt scenario.
That seems like a good idea, thank youranpitime wrote: ↑Thu May 17, 2018 5:26 pmHi,

Here is the faq how to do install it and what is needed:
You cold just Play around with this and check if all plc's are possible to connect.
