The first PLC module I want to make is a box that can hold Raspberry PI + 1 or 2 Hat’s. Having the capability to add a RPI 3 or RPI Zero W is a great asset. It also provide a solution for industrial mounting of a RPI.
This enables 4 PLC modules “as is”:
- Linux/Windows computing module
- 5 port RS485/CAN communication Gateway
- 16 channel Servo/IO
- 8 channel DC Motor, 8 channel Servo/IO
I will create more Hat’s so they can be added as PLC modules as well. I am a bit wage on the details around how to integrate Raspberry PI itself. I want PLC connectors in front and that leaves Ethernet + USB at bottom. The more problematic side is accessing the backbone – suggestions are most welcome.
