I am designing a network with a contrologix PLC. We are proposing to connect the drives and remote I/O using ethernet.
The controllogix rack will have 2 ethernet cards, one to connect to the customers network and one for the control. In total there will be about 22 nodes on the the control network.
I am worried about the amount of multicast traffic that will produced. I understand that a layer 2 switch, even though it supports IGMP snooping will not filter the multicast packets without a IGMP querier.
24 port industrial switches are not common (and expensive) and layer 3 19" rack mount switches are not cheap either.
My main question is there a layer 2 switch that has an IGMP querier and do I really need to worry about multicast if it confined to the control network?
Thanks
