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.

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.

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.
