You have just found the easiest way to move Modbus Registers and Coils between Modbus TCP/IP and Modbus RTU Network Devices. The BFR3000 offers transparent data transfer between Modbus devices and controllers on different physical layers. The BFR3000 has three operating modes making it your go-to device for moving data between Modbus Networks.
Modbus RTU Master to Modbus TCP/IP Client
The router becomes a shared block of Modbus registers and coils. Either protocol is able to read or write values to and from the shared block of data.
Modbus RTU Slaves to Modbus TCP/IP Client
Modbus RTU slaves are presented as Modbus TCP/IP servers. Requests sent to a Modbus TCP/IP node ID will be routed to the matching slave ID on the Modbus RTU network.
Modbus TCP/IP Servers to Modbus RTU Master
Modbus TCP/IP servers are presented as Modbus RTU slave. In the Gateway you define the IP address and unit ID’s of your Modbus server devices and then define what slave ID they will be mapped too.
