The PLC processor appears cleared, that is the reason for the blinking CPU FAULT led. If the processor configuration is cleared, you will need to use the default communication parameters in RSLinx to start talking to the processor.
(Did you check to make sure your module battery is OK? Is the Battery Low led on?)
Connect your RS-232 port on your computer directly to the DF1 communications port on the processor using the appropriate AB cable.
Verify your DF1 communication parameters.
From the menu, select Communications->RSWho
Right click on AB DF1-1, RS-485 (on the displayed RSWho’s list) and select Properties
The default communications properties for a cleared processor are 19,200 Baud, no parity and 1 stop bit, CRC error checking and make sure your station (RSLinx) address is set to something other than 01. Or just click the “Auto-configure” button.
