• Documenting the application configuration, for example, by making
printouts
• Saving application configurations as templates in an application library to
reuse them in other protection relays. Function blocks and the related logic
can be fully or partially reused depending on the functionality available in
the other protection relay.
• Validating the application configuration during the configuration process
on demand and while writing the application configuration to the protection
relay
For instructions on how to perform the different tasks in PCM600, see
PCM600 online help.

Function blocks

Function blocks are the main elements of an application configuration. They are
designed for a various number of functions and organized into groups according to
type. The different function block types are shown in the Object Types view. Function
block data can be modified with Application Configuration in PCM600.
• User-defined names can be given for function blocks and signals.
Signals that have a user-defined name created with Application
Configuration are visible in Parameter Setting in PCM600 only if
the relay configuration is written to the protection relay and read
back to PCM600. Otherwise, only the default signal name is
shown in Parameter Setting.
Restart the relay to ensure that all user-defined names for the
disturbance recorder's Channel id texts are updated on the LHMI,
WHMI and Parameter Setting menus.
If possible, set the user-defined name to a signal before
connecting the signal to other function blocks.
• IEC 61850, ANSI or IEC 60617 symbol standard can be set.
• IEC or ANSI naming style can be set.
• Function blocks can be locked.
• Visibility for execution order, cycle time and instance number can be set.
• Signals can be managed.
• Boolean inputs and outputs can be inverted.
