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.
TIP You can view the safety status via the safety status button on the online bar
(see page
142) or on the Safety tab of the Controller Properties dialog box,
as shown on page
121.
