Communication connections

The IED's LHMI is provided with an RJ-45 connector. The connector is intended for
configuration and setting purposes.
Rear communication via the X1/LAN1 connector uses a communication module with the
optical LC Ethernet connection.
The HMI connector X0 is used for connecting an external HMI to the IED. The X0/HMI
connector must not be used for any other purpose.
Rear communication via the X8/EIA-485/IRIG-B connector uses a communication
module with the galvanic EIA-485 serial connection.
Ethernet RJ-45 front connection
The IED's LHMI is provided with an RJ-45 connector designed for point-to-point use. The
connector is intended for configuration and setting purposes. The interface on the PC has
to be configured in a way that it obtains the IP address automatically if the DHCPServer
is enabled in LHMI. There is a DHCP server inside IED for the front interface only.
The events and setting values and all input data such as memorized values and disturbance
records can be read via the front communication port.
Only one of the possible clients can be used for parametrization at a time.
• PCM600
• LHMI
The default IP address of the IED through this port is 10.1.150.3.
The front port supports TCP/IP protocol. A standard Ethernet CAT 5 crossover cable is
used with the front port.
