• Insert function blocks, make connections and create variables
• Include the hardware I/O channels directly to the application configuration
• Calculate the execution order automatically by clicking Calculate execution
order on the toolbar.
• Document the application configuration: such as, make printouts
• Save application configurations as templates in an application library to reuse
them in other protection relays (Function blocks and related logic can be fully
or partially reused depending on the functionality available in the other
protection relay)
• Validate 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 the Application Configuration tool.
• User-defined names can be given for function blocks and signals.
Signals that have a user-defined name created with the Application
Configuration tool are only visible in the Parameter Setting tool if the
relay configuration is written to the protection relay and read back to
PCM600. Otherwise, the default signal name is shown in the
Parameter Setting tool.
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.
