The Secure Digital (SD) card provides nonvolatile storage for the CompactLogix 5370 L2

storing Logix Designer projects on the SD card or loading Logix Designer projects from an
SD card.
The following SD cards are available with for use with your CompactLogix 5370 L2 controller:
• 1784-SD1 card - 1 Gb of memory
• 1784-SD2 card - 2 Gb of memory
The CompactLogix 5370 L2 controllers are shipped from the factory with the 1784-SD1 SD
card installed.
Complete the following steps to re-install an SD card that has been removed from the controller
back into the controller or if installing a new SD card into the controller.
1. Verify that the SD card is locked or unlocked according to your preference.
Consider these points when
deciding whether to lock the card
before installation:
• If the card is unlocked, the
controller can write data to it or
read data from it.
• If the card is locked, the controller can only read data from it.
WARNING: When you insert or remove the SD card while 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.
