PCM600 communicates with the bay devices via an Ethernet connection. The
connection allows reading and writing all configuration data needed for proper
operation from or to the device. The devices have communication interfaces for
protocols and media used for station communication. IEC 61850 communication files
for a bay device or a complete station can be exported from PCM600 to station
engineering tools for engineering of station communication between bay devices and
station devices.
A PC with PCM600 can be connected to any 630 series protection relay within a
station using the Ethernet connection.
The Ethernet connection can then later also be used for service and maintenance
purposes. The connection is also used to handle disturbance records in COMTRADE
format from protection relays using the IEC 61850 file transfer.
The protection relays of today are designed on the concept of the IEC 61850 standard.
This is mainly given for the organization of functions represented by an equivalent
logical node in the IEC 61850 standard. The mapping between the logical node data
model in the device, following the structure and rules in part 7 of the IEC 61850
standard, and the function blocks in a device configuration is given in the IEC 61850
communication protocol manual.
The concept is also used for DNP3 protocol. The signals used or delivered by a
function block are automatically generated and available for station communication.
This concept allows a very efficient cost saving signal engineering.
The IEC 60870-5-103 protocol is engineered in Application Configuration tool and
Parameter Setting tool.
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's life
cycle. A set of special tools is available for different applications. The applications can
be organized in various ways.
• Product engineering
• Communication engineering per protocol
• System monitoring
• Product diagnostic
