Use a CompactFlash Card for
Data Storage
You can also store data to the CompactFlash memory card.
For example:
• A PanelView terminal changes tag values in a controller project. If power
to the controller is lost (and the controller is not battery backed up), the
program running in the controller, along with any values that were
changed by the PanelView terminal, will be lost. Use the CompactFlash
file system and logic in the project to store tag values as they change. When
the project reloads from the CompactFlash card, it can check the
CompactFlash card for any saved tag values and reload those into the
project.
• Store a collection of recipes on the CompactFlash card. When you need to
change a recipe, program the controller to read data for the new recipe
from a CompactFlash card.
• Program the controller to write data logs at specific time intervals.
Read and Write User Data to
the CompactFlash Card
A sample controller project that reads and writes from a CompactFlash card is
available with RSLogix 5000 Enterprise programming software. To display a list
of sample projects from a CompactFlash card, see
Sample Controller Projects on
page 102.
