Use a memory card reader Chapter 2
Edit the Load Mode option of the project (does not apply if the Load Image option is User Initiated).
To set the Load Mode option to: Then enter:
Program (Remote Only) PROGRAM
Run (Remote Only) RUN
For these controllers, you can use the memory card to store data and controller
projects.
• 1756 ControlLogix controllers, revision 13 and later
• 1756-L7x ControlLogix controllers, firmware revision 18 and later
• 1756 GuardLogix controllers, revision 18 and later
• 1769-L32E CompactLogix controllers, serial number SS0QZ000 and later
• 1769-L35E CompactLogix controllers, serial number SS0OR9GE and later
• CompactLogix 5370 controllers, revision 20 and later
Observe these examples:
• A PanelView terminal changes tag values in a controller project. If a
controller loses power, and is not battery backed up, it loses the program
running in the controller and the values changed by the PanelView
terminal. Use the memory card and logic in the project to store tag values as
they change. When the project reloads from the memory card, it can check
the memory card for any saved tag values and reload those into the project.
• Store a collection of recipes on the memory card. To change a recipe,
program the controller to read data for the new recipe from a memory card.
• Program the controller to write data logs at specific time intervals.
You can also use a memory card reader to read and write memory cards. This
method writes tag values in binary. You can read the data with any text editor, but
the data displays as the ASCII equivalent of the binary data.
For more information, see the sample projects available with the Logix Designer
application. In the application, from the Help menu, choose Vendor Sample
Projects to display a list of sample projects.
