Ethernet RJ-45 front connection

The protection relay is provided with an RJ-45 connector on the LHMI. The connector
is intended for configuration and setting purposes. The interface on the PC side has to
be configured in a way that it obtains the IP address automatically. There is a DHCP
server inside protection relay 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
• WHMI
The default IP address of the protection relay through this port is 192.168.0.254.
The front port supports TCP/IP protocol. A standard Ethernet CAT 5 crossover cable
is used with the front port.
The speed of the front connector interface is limited to 10 Mbps.
