Develop Safety Applications
You can use both standard (non-safety-related) and safety-related components in a safety control system. Within a safety project, you can perform standard automation control from standard tasks. Controllers with safety functions also support the same functions as other controllers. What differentiates these controllers from standard controllers is that the controllers also support a SIL 2 or SIL 3 capable safety task.
A logical and visible distinction is required between the standard and safety-related portions of the application. The
Studio 5000 Logix Designer®
application provides this differentiation via the safety task, safety programs, safety routines, safety tags, and safety I/O devices.
ATTENTION:
Performing online edits to logic, data, or the configuration can affect the safety functions of the system if the edits are performed while the application is running. Online edits should only be done if necessary. If the edits are not performed correctly, they can stop the application. You must use alternative safety measures and constraints during online edits.
