Generate a Safety Task Signature
Before verification testing, you must generate the safety task signature. You can
generate the safety task signature only when online with the safety-unlocked
GuardLogix controller in Program mode, and with no safety forces, pending
online safety edits, or safety faults. The safety status must be Safety Task OK.
In addition, you cannot generate a safety task signature if the controller is in
Run mode with run mode protection enabled.
Click Generate to generate the safety task signature from the Safety tab of the
Controller Properties dialog box. You can also choose Tools>Safety>Generate
Signature.
