Process Bus; Pcm600 Tool - ABB ABILITY SSC600 Operation Manual

Introduction
There are different alternative ways to connect a laptop or a workstation as SAN to a
PRP network.
• Via an external redundancy box (RedBox) or a switch capable of connecting to PRP
and normal networks
• By connecting the node directly to LAN A or LAN B as SAN

Process bus

Process bus IEC 61850-9-2 defines the transmission of Sampled Measured Values within
the substation automation system. UCA users' group created a guideline IEC 61850-9-2
LE that defines an application profile of IEC 61850-9-2 to facilitate implementation and
enable interoperability. Process bus is used for distributing process data from the primary
circuit to all process bus compatible IEDs in the local network in a real-time manner. The
data can then be processed by any IED to perform different protection, automation and
control functions.
Transmitting measurement samples over process bus brings also higher error detection
because the signal transmission is automatically supervised. Additional contribution to the
higher availability is the possibility to use redundant Ethernet network for transmitting
SMV signals.
The SSC600 supports receiving of sampled values of analog currents and voltages. The
measured values need to be transferred as sampled values using the IEC 61850-9-2 LE
protocol.
The SSC600 IEDs with process bus based applications use IEEE 1588 v2 Precision Time
Protocol (PTP) according to IEEE C37.238-2011 Power Profile for high accuracy time
synchronization. With IEEE 1588 v2, the cabling infrastructure requirement is reduced by
allowing time synchronization information to be transported over the same Ethernet
network as the data communications.

PCM600 tool

Protection and Control IED Manager PCM600 offers all the necessary functionality to
work throughout all stages of the IED life cycle.
• Planning
• Engineering
• Commissioning
• Operation and disturbance handling
• Functional analysis
The whole substation 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 customer needs.

Note: When using PTP in redundant mode, synchronization master is
primarily searched from LAN A. Synchronization master from LAN B is used
only, if no master in LAN A is detected.
Note: For more information, refer to PCM600 documentation.
