Guess a raspberry will work fine, also small enough to put on a din rail or similar. It must be a device cheap and readily available, I know some of devices similar as this used on raspberry have time triggered send of Ethernet messages which is nice but more than needed for a few axis but are not certain about this used in Raspberry. Used PLC with similar or same chip and it does not have any kind of local user interface instead I use Ethernet and ordinary to computer to communicate with it. Could follow what happen in real time and receive data sent periodically over Ethernet but could not be really certain which messages get priority if there is more traffic. Often use Youtube, it is more bandwidth but slower update rate and certain there is a receive buffer, most of the time but not always perfect then used for other things, it will however not make dents/scratchs in the monitor so is not very important.
