Chapter 2 Install the CompactLogix 5370 L1 Controller
Install the Secure
Digital Card
The CompactLogix 5370 L1 controller is shipped 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 to install a new SD card into the
controller.
We recommend that you leave the SD card in the controller, even when it is not
used. If the controller experiences a major non-recoverable fault, extended fault
information is saved to the card.
1. Verify that the SD card is locked or unlocked according to your
preference. Consider the following 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.
2. Open the door for the SD card.
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.
