This is a Dual Ethernet Module using M12-4 ports. I drafted this earlier. I need to use aSTM32H573 for this since the PHY chip is a 3 x Ethernet switch. The big point with this module is that it provides dual, redundant ethernets, Profinet and Ethercat capabilities.
I have Ethernet on the CAN Hub that I am still working on, but not every module need Ethernet so I am considering two modules – the one above and a single Ethernet based on W5500 or similar. The one above is straight forward – still a bit work in progress – while the W5500 one is ready to be ordered – 3D illustrated below.
The W5500 one can also deliver redundant Ethernet, but to my knowledge they cannot support Profinet RT or Ethercat. These will both be coming up soon, but I want to finish what I have first.
