Safety Application Development Chapter 6
Create the Project
The logic and instructions used in programming the application must be the
following:
• Easy to understand
• Easy to trace
• Easy to change
• Easy to test
All logic should be reviewed and tested. Keep safety-related logic and standard
logic separate.
Label the Program
The application program is clearly identified by one of the following:
• Name
• Date
• Revision
• Any other user identification
Test the Application Program
This step consists of any combination of Run and Program modes, online or
offline edits, upload and download, and informal testing that is required to get an
application running properly in preparation for the Project Verification test.
Generate the Safety Task Signature
The safety task signature is required to operate in a SIL3 safety function
The safety task signature uniquely identifies each project, including its logic, data,
and configuration. The safety task signature is composed of an ID (identification
number), date, and time.
You can generate the safety task signature if all of the following conditions are
true:
• RSLogix 5000® software is online with the controller.
• The controller is in Program mode.
• The controller is safety-unlocked.
• The controller has no safety forces or pending online safety edits.
• The safety task status is OK.
