Setting IED and communication
8.5.1
Communication settings
The IED is provided with an RJ-45 connector on the LHMI. The connector is
mainly used for configuration and setting purposes. The fixed IP address for the
front port is 192.168.0.254.
Different communication ports are available via optional communication modules.
Ethernet RJ-45 and optical Ethernet LC are the two rear port Ethernet
communication options. Rear port Ethernet is intended for station bus
communication. Communication protocols used via Ethernet ports are IEC
61850-8-1, DNP3 TCP/IP and Modbus TCP/IP. Optical ST-type glass fibre serial
and RS-485/RS-232 twisted pair can also be used for rear port communication.
Protocols available for serial communication are Modbus RTU/Modbus ASCII,
DNP3 and IEC 60870-5-103.
For more information, see the communication protocol manuals and
the technical manual.
If the protocol does not operate as expected, check that other serial
protocols are not using the COM port.
8.5.1.1
Serial communication ports and drivers
Depending on the hardware configuration, the IED can be equipped with one or
several UART-based serial communication ports. The communication ports can be
either galvanic (RS-485, RS-232) or fibre-optic. The IED uses serial ports and
drivers as different types of serial communication protocol links.
Serial ports are called COM1, COM2 and so on, depending on the number of serial
ports in the IED hardware configuration. Each COM port driver has its own setting
parameters found via the LHMI in
Configuration/Communication/COMn
(n= 1,2,
…).
Since the same IED usually supports a variety of different communication
hardware options, all COM port driver setting parameters are not relevant for every
communication hardware type.
