RUT956 as Protocol Converter: IEC 60870-5-104 (Client) to DNP3 (Outstation)

Hello Teltonika Support Team,

I am working on a project using a RUT956 and I need to implement a protocol conversion gateway.

My Architecture:

Field Side: A Remote Terminal Unit (RTU) communicating via IEC 60870-5-104.

Control Side: A SCADA system communicating via DNP3.

Gateway: The RUT956 needs to act as an IEC 104 Client to poll data from the RTU, and simultaneously as a DNP3 Outstation (Slave) to provide this data to the SCADA.

Current Progress:

I have already successfully configured the IEC 104 Client on the RUT956 and I am able to retrieve the variables (IOAs) from my field RTU. The data is visible and correctly polled by the router.

The Problem:

I cannot find a way to link or map these retrieved IEC 104 variables to the DNP3 Outstation service. I need these values to be available as DNP3 Point Indexes so my SCADA can read them.

My Questions:

1. Is there a native feature or a specific “Data Mapping” section in RutOS to bridge data between the IEC 104 Client and the DNP3 Outstation?

2. If a direct link is not available, do I need to use an intermediary service (like Modbus TCP mapping or a custom script) to move data from the IEC 104 buffer to the DNP3 registers?

3. Could you provide a configuration example for this specific bridging use case?

I have all the necessary protocol packages installed, but I am stuck on this “inter-protocol” communication step.

Thank you in advance for your assistance.
