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
5-9.
After a successful self-test, the DAT reads the DAT function file to determine its
configuration.
DAT Function File
DAT configuration is stored in the processor in a specialized configuration file
called the DAT Function File. The DAT Function File, which is part of the user’s
control program, is described in the
MicroLogix 1200 and MicroLogix 1500
Instruction Set Reference Manual , publication 1762-RM001B-US-P.
Following a successful power-up sequence, the DAT enters the bit monitoring
mode.
