Using Compactflash - Rockwell Automation Allen-Bradley DriveLogix 5730 User Manual

Using CompactFlash

The 1784-CF64 CompactFlash card provides nonvolatile memory storage
for the DriveLogix5730 controller. The card stores the contents of the
controller memory (program logic and tag values) and the controller
firmware at the time that you store the project. Storing information to the
CompactFlash card is like storing a snapshot of controller memory at a
given time.
ATTENTION: If you configured the CompactFlash card to
!
"restore on power up" and you make changes to a project, such
as online edits or changes to tag values, you must store the
project to the CompactFlash card again after you make changes.
Otherwise, your changes are not saved and you will lose those
changes on the next power cycle to the controller.
Tag values stored in flash are a snapshot at the time of the store. During a
program restore the processor tag values will be equal to tag data stored on
flash.
The locking tab on the front of the controller helps hold the CompactFlash
card in its socket.
ATTENTION: Do not remove the CompactFlash card while the
!
controller is reading from or writing to the card, as indicated by a
flashing green CF LED. This could corrupt the data on the card
or in the controller, as well as corrupt the latest firmware in the
controller.
The CompactFlash card supports removal and insertion under power.
ATTENTION: When you insert or remove the card while
! backplane power is on, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector. Worn
contacts may create electrical resistance that can affect module
operation.
See the Logix5000 Controllers Common Procedures Programming Manual,
publication 1756-PM001 for steps on storing an image on the
CompactFlash card.
