measured values can be supervised with four
settable limits that is low-low limit, low limit,
high limit and high-high limit. The measure
value expander block (RANGE_XP) has been
introduced to be able to translate the integer
output signal from the measuring functions to
5 binary signals that is below low-low limit,
below low limit, normal, above high-high
limit or above high limit. The output signals
can be used as conditions in the configurable
logic.
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 binary input module and then read by
the pulse counter function. A scaled service
value is available over the station bus. The
special Binary input module with enhanced
pulse counting capabilities must be ordered
to achieve this functionality.
Function for energy calculation and
demand handling ETPMMTR
Outputs from Measurements (CVMMXU)
function can be used to calculate energy.
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.
Basic IED functions
Time synchronization
Use the time synchronization source selector
to select a common source of absolute time
for the IED when it is a part of a protection
system. This makes comparison of events and
disturbance data between all IEDs in a station
automation system possible.
Human machine interface
The local HMI is divided into zones with
different functionality.

• Status indication LEDs.
• Alarm indication LEDs, which consist of
15 LEDs (6 red and 9 yellow) with user
printable label. All LEDs are configurable
from PCM600.
• Liquid crystal display (LCD).
• Keypad with push buttons for control
and navigation purposes, switch for
selection between local and remote
control and reset.
• Isolated RJ45 communication port.

Station communication
Overview
Each IED is provided with a communication
interface, enabling it to connect to one or
many substation level systems or equipment,
either on the Substation Automation (SA) bus
or Substation Monitoring (SM) bus.
Following communication protocols are
available:
