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.

Station communication rear connection

The default IP address of the IED through the Ethernet connection is 192.168.1.10.
The physical connector is X1/LAN1. The interface speed is 100 Mbps for the 100BASE-
FX LC alternative.
Optical serial rear connection
Serial communication can be used via optical connection in star topology. Connector
type is glass (ST connector). Connection's idle state is indicated either with light on or
light off. The physical connector is X9/Rx,Tx.
EIA-485 serial rear connection
The communication module follows the EIA-485 standard and is intended to be used in
multi-point communication.
