t per phase with alarm and lockout
• remaining breaker life per phase
• breaker inactivity

13. Metering

Pulse counter logic PCGGIO
Pulse counter (PCGGIO) function counts externally generated
binary pulses, for instance pulses coming from an external energy
meter, for calculation of energy consumption values. The pulses
are captured by the BIO (binary input/output) module and then
read by the PCGGIO function. A 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.

14. Human Machine interface

Local HMI
ANSI12000175 V1 EN
Figure 10. Local human-machine interface
The LHMI of the IED contains the following elements:
• Display (LCD)
• Buttons
• LED indicators
• Communication port for PCM600
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
30
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 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 defined and also
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

15. 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 presented on the
LHMI and in PCM600 event viewer tool.
Time synchronization
Use a common global source for example GPS time
synchronization inside each substation as well as inside the area
of the utility responsibility to achieve a common time base for the
IEDs in a protection and control system. This makes comparison
and analysis of events and disturbance data between all IEDs in
the power system possible.
Time-tagging of internal events and disturbances are an excellent
help when evaluating faults. Without time synchronization, only
the events within the IED can be compared to one another. With
time synchronization, events and disturbances within the entire
station, and even between line ends, can be compared during
evaluation.
In the IED, the internal time can be synchronized from a number of
sources:
• SNTP
• IRIG-B
• DNP
• IEC60870-5-103
