values will happen in both forward and reverse directions.
These energy values are available as output signals and also
as pulse outputs. Integration of energy values can be
controlled by inputs (STARTACC and STOPACC) and
EnaAcc
setting and it can be reset to initial values with RSTACC
input.
The maximum demand for active and reactive powers are
calculated for the set time interval
tEnergy
and these values
are updated every minute through output channels. The
active and reactive maximum power demand values are
calculated for both forward and reverse direction and these
values can be reset with RSTDMD input.

Local human-machine interface
The LHMI of the IED contains the following elements:
• Graphical display capable of showing a user defined single
line diagram and provide an interface for controlling
switchgear.
• Navigation buttons and five user defined command buttons
to shortcuts in the HMI tree or simple commands.
• 15 user defined three-color LEDs.
• Communication port for PCM600.
The LHMI is used for setting, monitoring and controlling.
12. Basic IED functions
Time synchronization
M11344-3 v9
The time synchronization function is used to select a common
source of absolute time for the synchronization of the IED
when it is a part of a protection system. This makes it
possible to compare events and disturbance data between all
IEDs within a station automation system and in between sub-
stations.
13. Station communication
Communication protocols
M14815-3 v12
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.
Available communication protocols are:
• IEC 61850-8-1 communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
• DNP3.0 communication protocol
Several protocols can be combined in the same IED.
IEC 61850-8-1 communication protocol
M14787-3 v13
IEC 61850 Ed.1 or Ed.2 can be chosen by a setting in
PCM600. 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 electrical Ethernet
front port. IEC 61850-8-1 protocol allows intelligent electrical
devices (IEDs) from different vendors to exchange information
and simplifies system engineering. IED-to-IED communication
using GOOSE and client-server communication over MMS are
supported. Disturbance recording file (COMTRADE) uploading
can be done over MMS or FTP.
The front port shall not be used due to
interference.
LON communication protocol
SEMOD120140-5 v2
Existing stations with ABB station bus LON can be extended
with use of the optical LON interface. This allows full SA
functionality including peer-to-peer messaging and
cooperation between the IEDs.
SPA communication protocol
SEMOD120134-5 v1
A single glass or plastic port is provided for the ABB SPA
protocol. This allows extensions of simple substation
automation systems but the main use is for Substation
Monitoring Systems SMS.
