REC615 and RER615 DNP3 Communication Protocol Manual

After its activation, an instance should be attached to the intended client.

If the client is in a serial connection, the instance must be attached to the intended serial port.

In case of a TCP client, the instance must be first attached to the physical Ethernet port. If there are several TCP client connections, the protection relay must be able to distinguish between the clients. There are two setting parameters in an instance.

  • Client IP: When the client makes the TCP connection, its IP address is checked. This instance is given to the client with this IP address. It is also possible to use the address “0.0.0.0” if no client IP address is to be defined. In this case, the client's IP address is ignored.
  • TCP port: This parameter can be used in conjunction with the Client IP setting, thus allowing only a certain IP address at a specific TCP socket port number.
