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 29 - Nonvolatile Memory Tab
For detailed information on using nonvolatile memory, refer to the Logix5000
Controllers Nonvolatile Memory Programming Manual, publication
1756-PM017 .
Storing 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 exists in the controller, you can save just the firmware of the
safety controller only if valid partnership exists. A firmware-only load will 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.
