Communication

The IED supports communication protocols IEC 61850-8-1, IEC 60870-5-103,DNP3 over TCP/IP and
serial communication via RS485.
All operational information and controls are available through these protocols. However, some
communication functionality, for example, horizontal communication (GOOSE) between the IEDs,
is only enabled by the IEC 61850-8-1 communication protocol.
The serial communication follows the EIA-485 standard and is intended to be used in multi-point
communication.
Disturbance files are accessed using the IEC 61850 or IEC 60870-5-103 protocols. Disturbance files
are also available to any Ethernet based application in the standard COMTRADE format. The IED
can send binary signals to other IEDs (so called horizontal communication) using the IEC 61850-8-1
GOOSE (Generic Object Oriented Substation Event) profile. Binary GOOSE messaging can, for
example, be employed for protection and interlocking-based protection schemes. The IED meets
the GOOSE performance requirements for tripping applications in distribution substations, as
defined by the IEC 61850 standard. Further, the IED supports the sending and receiving of analog
values using GOOSE messaging. Analog GOOSE messaging enables fast transfer of analog
measurement values over the station. The IED interoperates with other IEC 61850 compliant IEDs,
tools and systems and simultaneously reports events to five different clients on the IEC 61850
station bus. For a system using DNP3 over TCP/IP, events can be sent to four different masters.
For systems using IEC 60870-5-103 IED can be connected to one master in a station bus with star-
topology.
All communication connectors, except for the front port connector, are placed on integrated
communication modules. The IED is connected to Ethernet-based communication systems via the
RJ-45 connector (10/100BASE-TX) or the fibre-optic multimode LC connector (100BASE-FX).

management
Changes in user management settings do not cause an IED reboot.
After three consecutive failed login attempts the user will be locked out for ten
minutes before a new attempt to log in can be performed. This time is settable 10
minutes to 60 minutes.
The PCM600 tool caches the login credentials after successful login for 15 minutes.
During that time no more login will be necessary.
