Chapter 1 Prepare the CompactLogix 5370 L1 Controller Hardware
Install the Secure Digital Card
The SD card provides nonvolatile storage for the CompactLogix 5370 L1 controller. You can store Logix Designer projects
to an SD card or load a Logix Designer project from an SD card.
The following SD cards are available for use with your CompactLogix 5370 L1 controller:
• 1784-SD1 card - 1 GB of memory
• 1784-SD2 card - 2 GB of memory
The CompactLogix 5370 L1 controllers ship from the factory with the 1784-SD1 SD card installed.
Complete these steps to reinstall 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 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.
