The LHMI includes three LEDs for indicating the state of the protections and of the relay functions. A further 8 alarm LEDs are
available on the front of the LHMI. By means of these 8 LEDs it is possible to display the state of 24 alarms organized into three
pages. The “Alarm page” button allows switching among the various LED pages. These LEDs can be configured by means of
PCM600.

5.3.7.17. Parameter management
The LHMI allows the IED parameters to be accessed. Three
types of parameters can be read or written:
– Numerical values
– Strings
– Enumeration
The numerical values are presented both in full and decimal
form with one minimum and one maximum value. The string
parameters can be entered character by character. The
enumerated parameters have a set of pre-established values
within which they can vary.
5.3.7.18. Front communication port
The RJ45 type communication port allows connection to the
RBX615 relay.
When a computer is connected with the IED, the DHCP server
of the IED for the front port assigns an IP address to the
computer. The IP address of the front port is fixed and is
192.168.0.254
