Checking Safety Programs and Safety Parameters
You can verify beforehand whether your safety programs (user program for safety controls that
runs on the Safety CPU Unit) and safety parameters (parameters that are used for safety controls)
meet the validity and safety aspects that are outlined below.
•
Validity and safety issues related to function block diagram programs, such as missing or incor-
rect connection for function blocks
• Safety issues, such as the incorrect connection of a standard input to a safety input parameter of
a function block
• Validity of the safety task period
These checks help to prevent design regression and help to ensure the reliability of the safety de-
signs.

Debugging function
You can connect the Sysmac Studio to perform various types of debugging, including monitoring,
