So whenever I have been working on new projects, and need remote IO, I typically install 2 network cards In the backplane and create 2 separate networks, 1 for the remote IO and one for the main network.
I have a situation where that didn't get done, and seems to be adding too much network traffic. I have an L72 PLC with a full backplane and only 1 Ethernet card. and a remote backplane with 9 full slots and again only 1 Ethernet card. I have 2 managed Hirschmann RS-20 switches, one that wasn't needed, and one that is completely full of devices, including a line back to the main network switch.
My question is basically this, is it possible (using IGMP ?) to separate the traffic between the remote IO and the PLC, but still have access to the PLC from the main network, using only managed switch with the correct settings? Otherwise, the only way I know to do this would be to buy a bigger backplane, and install a 2nd Ethernet card.
I have attached an image better explaining what I have. The green highlighter showing traffic that needs to be separated from the blue highlighter.
any tips or suggestions would be much appreciated!
