14. 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 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 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.
15. Basic IED functions
Time synchronization
The time synchronization source selector is used to select a
common source of absolute time for the IED when it is a part of
a protection system. This makes it possible to compare event
and disturbance data between all IEDs in a station automation
system.

16. Human machine interface

Human machine interface
The local human machine interface is available in a medium
sized model. Up to 12 single line diagram pages can be
defined, depending on the product capability.
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.

17. 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:
• IEC 61850-8-1 communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
• DNP3.0 communication protocol
Theoretically, several protocols can be combined in the same
IED.
IEC 61850-8-1 communication protocol
The IED is equipped with single or double optical Ethernet rear
ports (order dependent) for IEC 61850-8-1 station bus
communication. The IEC 61850-8-1 communication is also
possible from the optical Ethernet front port. IEC 61850-8-1
protocol allows intelligent electrical devices (IEDs) from different
vendors to exchange information and simplifies system
engineering. Peer-to-peer communication according to GOOSE
is part of the standard. Disturbance files uploading is provided.
