Dear All
Greetings!

I am using redundant pair of controller X20CP3687x and I have to connect 308 modbus TCP Slaves to the controller, Can I connect all the 308 on a single port? If not can I use 2 X20BC0087 and connect 103, 103 slaves to each BC and 102 to the controller itself?

Thanks and regards

In theory that should work, but it all depends on the amount of data and refresh times. The X20BC0087 is not a solution for this because it is a modbusTCP bus controller for X20 IOs. With that many Modbus slaves, you may want to look at this library solution.
