Since you brought it up...The OP is trying to implement a multi level automation system the 'cost efficient' way.
Multiple LANs bridged by multiple ENB(2, 3)Ts is the Purdue Model standard, however, 'VLAN-ing' and managed switching at 'low' levels (Device/IO/Peer-to-Peer/HMI) seems to be more and more attempted seemingly for reducing the backbone media costs.
I am pretty sure there is some combination of switch settings which could get the OP's system up and going, however, I am already feeling sorry for the engineering personnel tasked with keeping the system functional and develop it in the future.
