Rockwell Automation 1764-xxxx MICROLOGIX 1500 PROGRAMMABLE CONTROLLERS - Manual (Page 95)

Publication 1764-UM001B-EN-P - April 2002
Using Trim Pots and the Data Access Tool (DAT) 5-3
Power-Up Operation
The DAT receives power when it is plugged into the controller. Upon
power-up, the DAT performs a self-test.
If the test fails, the DAT displays an error code, all indicator lights are
deactivated, and the DAT does not respond to any key presses. See
DAT Error Codes on page 5-10.
After a successful self-test, the DAT reads the DAT function file to
determine its configuration.
