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 HMI
IEC13000239 V3 EN-US
Figure 7. 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.

17. Basic IED functions

Time synchronization
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
38
IEDs within a station automation system and in between sub-
stations. A common source shall be used for IED and merging
unit when IEC/UCA 61850-9-2LE process bus
communication is used. For Phasor Measurement Unit (PMU)
an accurate time synchronization is essential to allow the
comparison of phasors measured at different locations in a
Wide Area Monitoring System (WAMS).
Precision time protocol PTP
AMU0600442 v14
PTP according to IEEE 1588-2008 and specifically its profile
IEC/IEEE 61850-9-3 for power utility automation is a
synchronization method that can be used to maintain a
common time within a station. This time can be synchronized
to the global time using, for instance, a GPS receiver. If PTP
is enabled on the IEDs and the switches that connect the
station are compatible with IEEE 1588, the station will
become synchronized to one common time with an accuracy
of under 1us. Using an IED as a boundary clock between
several networks will keep 1us accuracy on three levels or
when using an HSR, 15 IEDs can be connected in a ring
without losing a single microsecond in accuracy.

18. Ethernet

Access points
An access point is an Ethernet communication interface for
single or redundant station communication. Each access
point is allocated with one physical Ethernet port, two
physical Ethernet ports are allocated if redundant
communication is activated for the access point.

DHCP is available for the front port, and a device connected
to it can thereby obtain an automatically assigned IP-address.
Access points diagnostics
The access point diagnostics function blocks (RCHLCCH,
SCHLCCH and FRONTSTATUS) supervise communication.
SCHLCCH is used for communication over the rear Ethernet
ports, RCHLCCH is used for redundant communications over
the rear Ethernet ports and FRONTSTATUS is used for
communication over the front port. All access point function
blocks include output signal for denial of service.
