21. Station communication

Communication protocols
Each IED is provided with several communication interfaces
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
• IEC/UCA 61850-9-2LE communication protocol
• LON communication protocol
• SPA communication protocol
• IEC 60870-5-103 communication protocol
• DNP 3.0 communication protocol
Several protocols can be combined in the same IED.
The LPHD.PhyHealth reflects the physical
health of the IED. The status is set to Alarm
when there is an internal failure in the IED
or Warning if any active communication link
fails.
IEC 61850-8-1 communication protocol
IEC 61850 Ed.1 or Ed.2 can be chosen by a setting in
PCM600. The IED is equipped with up to six (order
dependent) optical Ethernet rear ports 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 is only intended for PCM600
communication, maintenance, training and
test purposes due to risk of interference
during normal operation.
Front port is not available in the IED's with
blank front panel. By default, AP1 is
available for engineering and maintenance.
IEC 61850 quality expander QUALEXP
The quality expander component is used to display the
detailed quality of an IEC/UCA 61850-9-2LE analog
channel. The component expands the channel quality output
M14815-3 v15
of a Merging Unit analog channel received in the IED as per
the IEC 61850-7-3 standard. This component can be used
during the ACT monitoring to get the particular channel
quality of the Merging Unit.
Supervision of GOOSE subscription (ALGOS)
ALGOS reports the status of GOOSE communication to a
client according to IEC 61850.
There should be one instance of ALGOS in an IED for each
data set that the IED receives from other IEDs. Each
ALGOS reports the status of the receiving GOOSE
communication.
All attributes, both mandatory and optional, according to
IEC 61850-7-4 Ed. 2.0 are supported.
ALGOS is not defined in IEC 61850 Ed. 1
and is only supported in Ed. 2 mode.
Supervision of sampled value (IEC 61850-9-2LE)
subscription (ALSVS)
M14787-3 v17
ALSVS reports the status of sampled value communication
to a client according to IEC 61850.
There should be one instance of ALSVS in an IED for each
sampled value data stream that the IED receives. Each
ALSVS reports the status of one receiving sampled value
data stream.
The attributes St and SimSt are supported as well as the
setting SvCBRef, according to IEC 61850-7-4 Ed. 2.0.
ALSVS is not defined in IEC 61850 Ed. 1
and is only supported in Ed. 2 mode.
IEC/UCA 61850-9-2LE communication protocol
Optical Ethernet port communication standard IEC/UCA
61850-9-2LE for process bus is supported. IEC/UCA
