Chapter 9 Use a CompactFlash Card
Use a CompactFlash Card to
Load/Store a User
Application
You can load the user application/project from nonvolatile memory/
CompactFlash to the user memory of the controller:
on every power-up.
on corrupt memory.
anytime through RSLogix 5000 programming software.
When you store a project to a 1784-CF128 Industrial CompactFlash memory
card, the controller formats the card, if required.
Manually Change Which Project Loads
A CompactFlash card stores multiple projects. By default, the controller loads the
project that you most recently stored, according to the load options of that
project.
ATTENTION: Fault conditions can occur if the controller types do not match. For
example, if the CompactFlash user program and controller firmware were
created for a 1769-L35E controller, and then an attempt was made to load that
program and/or firmware into a 1769-L32E controller.
The user application and firmware version on the CompactFlash card is loaded
into the controller. If the contents of the CompactFlash card are a different
revision than the revision that is on the controller, then the controller will be
updated to the revision on the CompactFlash card.
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 status
indicator. Doing so could corrupt the data on the card or in the controller, as well
as corrupt the latest firmware in the controller.
CompactFlash card memory stores the contents of the user memory when you
store the project.\
Changes made after you store the project are not reflected in CompactFlash
card memory.
If you change the project but do not store those changes, you overwrite
them when you load the project from the CompactFlash card. If this occurs,
you have to upload or download the project to go online.
If you want to store changes such as online edits, tag values, or a
ControlNet network schedule, store the project again after you make the
changes.
Be aware that when loading a different project, the firmware revisions must be
the same.
