scaled service value is available over the
station bus.
Function for energy calculation and
demand handling ETPMMTR
Outputs from the Measurements (CVMMXN)
function can be used to calculate energy
consumption. Active as well as reactive
values are calculated in import and export
direction. Values can be read or generated as
pulses. Maximum demand power values are
also calculated by the function.

Figure 6. Local human-machine interface
The LHMI of the IED contains the following
elements:
• Display (LCD)
• Buttons
• LED indicators
• Communication port
The LHMI is used for setting, monitoring and
controlling .
The Local human machine interface, LHMI
includes a graphical monochrome LCD with a
resolution of 320x240 pixels. The character
size may vary depending on selected
language. The amount of characters and rows
fitting the view depends on the character size
and the view that is shown.
The LHMI can be detached from the main
unit. The detached LHMI can be wall
mounted up to a distance of five meters from
the main unit. The units are connected with
the Ethernet cable included in the delivery.
The LHMI is simple and easy to understand.
The whole front plate is divided into zones,
each with a well-defined functionality:
• Status indication LEDs
• Alarm indication LEDs which can
indicate three states with the colors
green, yellow and red, with user
printable label. All LEDs are configurable
from the PCM600 tool
• Liquid crystal display (LCD)
• Keypad with push buttons for control
and navigation purposes, switch for
selection between local and remote
control and reset
• Five user programmable function buttons
• An isolated RJ45 communication port for
PCM600
13. Basic IED functions
Self supervision with internal event
list
The Self supervision with internal event list
(INTERRSIG and SELFSUPEVLST) function
reacts to internal system events generated by
the different built-in self-supervision
elements. The internal events are saved in an
internal event list.
Time synchronization
Use time synchronization to achieve a
common time base for the IEDs in a
protection and control system. This makes
comparison of events and disturbance data
between all IEDs in the system possible.
