3.8 Station communication
Operational information and controls are available through a wide range of
communication protocols including IEC 61850 Edition 2, IEC 61850-9-2 LE, IEC
60870-5-103, IEC 60870-5-104, Modbus
®
and DNP3. Full communication capabilities,
for example, horizontal communication between the relays, are only enabled by IEC
61850.
The relay provides the possibility for a second IP address and a second subnetwork
when the communication modules with three Ethernet ports (COM1001...1003) are
used. However, only one IP network can be used as the default route. Using two
IP addresses, communication networks can be separated based on the dominant
user’s needs. For example, one IP address can serve the dispatchers and the other
one can serve the service engineers’ needs.
The IEC 61850 protocol is a core part of the relay as the protection and control
application is fully based on standard modelling. The relay supports Edition 2 and
Edition 1 versions of the standard. With Edition 2 support, the relay has the latest
functionality modelling for substation applications and the best interoperability for
modern substations. The relay supports flexible product naming (FPN) facilitating
the mapping of relay’s IEC 61850 data model to a customer defined IEC 61850 data
model.
3.9 PCM600
Protection and Control IED Manager PCM600 offers all the necessary functionality
to work throughout all stages of the protection relay's life cycle.
• Planning
• Engineering
• Commissioning
• Operation and disturbance handling
• Functional analysis
The whole substation configuration can be controlled and different tasks and
functions can be performed with the individual tool components. PCM600 can
operate with many different topologies, depending on the project needs.
For more information, see the PCM600 documentation.
3.9.1 Connectivity packages
A connectivity package is a software component that consists of executable code
and data which enable system tools to communicate with a protection relay.
Connectivity packages are used to create configuration structures in PCM600. The
latest PCM600 and connectivity packages are backward compatible with older
protection relay versions.
