1769-L31 CompactLogix™ Controller
Install a 1784-CF64 Industrial CompactFlash Card (optional)
ATTENTION
A 1784-CF64 Industrial CompactFlash card provides nonvolatile memory for a
CompactLogix controller. This is an optional feature and is not required to operate
the controller. Install the card as follows:
1. Push the locking tab to the right and insert the 1784-CF64 Industrial
CompactFlash card into the socket on the front of the controller.
The label of the CompactFlash card faces towards the left. Match the
orientation arrow on the card with the arrow on the front of the controller.
The CompactFlash card support removal and
insertion under power.
WARNING
To remove the CompactFlash card, push the locking tab away from the
CompactFlash card and pull the CompactFlash card from the socket.
Publication 1769-IN069A-EN-P - March 2004
Do not remove the CompactFlash card while the controller is
reading from or writing to the card, as indicated by a flashing
green CF LED. This could corrupt the data on the card or in the
controller, as well as corrupt the latest firmware in the controller.
When you insert or remove the card
while backplane 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. Repeated electrical arcing
causes excessive wear to contacts on
both the module and its mating
connector. Worn contacts may create
electrical resistance that can affect
module operation.
