Protection and Control IED Manager PCM600 offers all the necessary functionality
to work throughout all stages of the protection relay 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.
PCM600 is used to conduct complete engineering and configuration activities needed
for the bay level protection relays.
Connectivity Packages are separate software packages that provide type and version
information to PCM600. Further Connectivity Packages assist the tool with
communications.
PCM600 uses IEC 61850 over Ethernet to communicate with bay devices. This
communication allows PCM600 to configure and monitor the devices. In addition to
IEC 61850 the devices have optional communications protocols and hardware to
connect to station engineering tools. PCM600 provides the ability to export the
configuration of the devices or an entire substation in a standard file format which
enables station engineering in separate IEC 61850 System Configuration tools.
A PC with PCM600 can be connected to any 611 series IED within a station by using
the Ethernet connection. The connection can also be used for service and maintenance
purposes. In addition, the connection is used to handle disturbance records from the
protection relays.
The modern-day protection relays are designed using the concept of the IEC 61850
standard. This is primarily in regards to how functions within the protection relay are
modelled and how the protection relay is represented in the substation. See the IEC
61850 parameter list for the list of logical nodes available in the protection relay and
observe how they follow the structure and rules as defined in part 7 of the standard.
The engineering of the used communication protocols is a separate task and an
addition to the engineering of protection and control functions.
PCM600 can be used for different purposes throughout the protection relay life cycle.
A set of special tools is available for different applications.
The applications can be organized into groups.
• Relay engineering
• Communication engineering
• Record management
• Device monitoring and diagnostic

3.1 Connectivity packages
A connectivity package is a software component that consists of executable code and
data which enables 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.
A connectivity package includes all of the data which is used to describe the protection
relay, for example, it contains a list of the existing parameters, data format used, units,
setting range, access rights and visibility of the parameter. In addition, it contains code
which allows software packages that consume the connectivity package to properly
communicate with the protection relay. It also allows for localization of text even
when its read from the protection relay in a standard format such as COMTRADE.
Update Manager is a tool that helps in defining the right connectivity package versions
for different system products and tools. Update Manager is included with products
that use connectivity packages.
