I designed a PLC with 3 x CAN ports earlier using M12 connectors and decided that I wanted a version that could be used on my desk or in a cabinet without the extra M12/Waterproof fuzz. It is the same design with a few tweaks:
- 3 x CAN ports on the motherboard
- Two motherboards or 3 extra modules with a total of 6 ports in a box.
- Designed for a standard metal box
- Use standard D-Sub 9
- Ethernet
- SD Card
- USB
- Full galvanic issolation on 24V and all ports.
With this I can mount a 6 port CAN w/USB/Ethernet or a 3 port CAN + 3 port Serial as needed. The final module fit in a metal box that either can be a stand-alone tool or be used as a module in a larger system, but this time with Ethernet as backbone. This will be a nice product, but the main reason I make it is because I need it myself.
The board mount into one of the box sides, but use flat-cables to connectors on the right side. The board is still a bit work in progress, but the box will have the exact same size as the Analogue board/box making them modules in the same system.
