before removing it.
• We recommend that you do the following:
–Leave an SD card installed.
– Use the SD cards available from Rockwell Automation (catalog number
1784-SD1 or 1784-SD2).
• While other SD cards can be used with the controller, Rockwell Automation
has not tested the use of those cards with the controller. If you use an SD
card other than those cards that are available from Rockwell Automation,
you can experience data corruption or loss.
• Also, SD cards that are not provided by Rockwell Automation do not have
the same industrial, environmental, and certification ratings as those cards
that are available from Rockwell Automation.
1. Verify that the SD card is not in use by checking to be sure that the
SD indicator is Off.
TIP
2. Open the door to access the SD card.
3. Press and release the SD card to eject it.
