Chapter 8 Store and Load Projects Using Nonvolatile Memory
If a memory card is installed, you can view the contents of the card on the
Nonvolatile Memory tab of the Controller Properties dialog box. If a safety
application is stored on the card, the safety-lock status and the safety task
signature are shown.
Figure 30 - Nonvolatile Memory Tab
For detailed information on using nonvolatile memory, refer to the

Store a Safety Project You cannot store a safety project if the safety task status is Safety Task
Inoperable. When you store a safety project, the firmware of both the primary
controller and the safety partner are saved to the memory card.
If no application project exists in the controller, you can save only the firmware
of the safety controller if a valid partnership exists. A firmware-only load does
not clear a Safety Task Inoperable condition.
ATTENTION: Do not remove the memory card while the controller is reading
from or writing to the card, as indicated by a flashing green OK status
indicator. This could corrupt the data on the card or in the controller, as well
as corrupt the latest firmware in the controller. Leave the card in the
controller until the OK status indicator turns solid green.
