8.5 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.
There are four options for rear port communication intended mainly for station level
communication, that is station bus. The options are galvanic Ethernet (RJ-45), optical
Ethernet (LC), optical ST-type glass fibre serial and RS-485/RS-232 twisted pair.
Communication protocols used via Ethernet ports are IEC 61850-8-1, Modbus TCP/
IP and DNP 3.0 TCP/IP. Protocols available for RS-485/RS-232 serial port are
Modbus RTU/Modbus ASCII, DNP 3.0 and IEC 60870-5-103.
For more information, see the Modbus communication protocol
manual and technical manual.
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.

1)
Fiber mode 0 = No fiber Used in the fiber-optic mode only.
Note that
No fiber
mode is the same
as the galvanic mode.
1 = Fiber light ON/loop
2 = Fiber light OFF/loop
3 = Fiber light ON/star
4 = Fiber light OFF/star
