Modbus RTU manager – subordinate topology

This is a typical use case for Modbus RTU integration via RS485. The BA device is the Modbus RTU manager, and the peripheral devices are Modbus RTU subordinates. Modbus RTU is using the COM1 - COM4 interface (depending on the controller type).

Modbus TCP client – server topology

This is a typical use case for Modbus TCP integration via RS485. The BA device is the Modbus TCP client and the peripheral devices are Modbus TCP servers. Modbus TCP uses the Ethernet port.
