I have one application where Micrologix 1400 PLC acts as Modbus TCP Master/Client, and it is connected to 8 Modbus TCP slave/server. When I start communication it gets slower, some slave are not responding.
In our setup we have used DES-1008C 8-Port 10/100 Mbps unmanaged Switch. With same setup if I reduced slaves to 4, then it works fine. So what could be problem?
Here I have one question of switch, which switch should i use, managed or unmanaged?
For future expansion I have to increase slaves up to 24 numbers in one network.
