• Insert function blocks, make connections and create variables.
• Include the hardware IO channels directly in the application configuration.
• Set function blocks and signal visibility to SMT.
• Document the application configuration, for example to make printouts.
• Test the application configuration online.
• Save application configurations as templates in an application library to
reuse them in other IEDs.
• Validate the application configuration during the configuration process
on demand and while writing the application configuration to the IED.
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 in type groups.
The different function block types are shown in the Object Types View.
28 presents an overview of the main parts that are relevant for function blocks.
• Set user defined names for function blocks and signals marked with blue text.
Signals that have a user defined name created in ACT, will
only be visible in PST if the IED configuration is written to the
IED and read back to PCM600. Otherwise the default signal
name is shown in PST.
Do not use other characters than a-z, A-Z, 0-9 and _ when
setting user defined names for signals and function blocks,
since other characters might not display properly in local HMI.
Also avoid using space character.
• Set IEC or/and ANSI naming style.
• Lock function blocks.
• Set visibility for execution order, cycle time and instance number.
• Manage signals, for example hide, show and rearrange.
• Invert Boolean inputs and Boolean outputs.
SMT is not supporting signals of integer type or group
signals. So, even if these types of signals are set as
visible for SMT, they will not be shown in SMT.
