Hi,
I currently have a RevPi Core S, I have set this up as a Modbus Master (TCP), linking via ethernet to a 3rd party sensor (Modbus Slave). This connection is successful and RevPi has data in terminal.
We also need to link the same RevPi to a Raspberry Pi 4. This second pi is used to show the user to above setup, showing a user interface the recorded data.
3rd Party Sensor >---Eth---> Rev Pi Core S >--- ? ---> Raspberry Pi 4
Rev Core - Both USB available, Micro USB port available. (Single Eth Port in use)
Second RaspberryPi - all ports available
? How should I link the two devices, allowing for (wired) data transfer from RevPi to Pi?
Current theory is using a USB-to-Eth adaptor, to allow the two to link.
Connecting RevPi Core to secondary RaspberryPi 4
Re: Connecting RevPi Core to secondary RaspberryPi 4
Is it important that there is a point-to-point connection between the Revolution Pi and Raspberry Pi devices?
Before you introduce a USB-Ethernet interface for a second Ethernet interface on the RevPi Core, you can simply use a network switch.
You can then transfer the data in different ways, for example via SSH with keys. Then you can simply work with commands via SSH that are executed on the remote machine:
