IEC 61850 interface in the IED and tools

8.1.1

Function view for IEC 61850 in PCM600

The IED function blocks have a design based on the demands and advantages of the IEC 61850
standard. This means that there is a strict relation between the function blocks and the logical
node types. This relation is automatically handled by the PCM600 tools.
The concept in IED is such that the 61850 data for each function instantiated in ACT will be
automatically created. This means that the user do not need to handle any instance
information for the functions regarding IEC 61850.
8.1.2

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.

The IEC/UCA 61850-9-2LE process bus communication protocol enables an IED to
communicate with devices providing measured values in digital format, commonly known as
Merging Units (MU). The rear access points are used for the communication.
The merging units (MU) are called so because they can gather analog values from one or more
measuring transformers, sample the data and send the data over process bus to other clients
(or subscribers) in the system. Some merging units are able to get data from classical
measuring transformers, others from non-conventional measuring transducers and yet others
can pick up data from both types.

When configuring RER670 for 9-2LE streams in a 16.7Hz system, the IED shall be
set to 16.7Hz and the MU to 50Hz (4kHz sampling).
