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-RM001.
Following a successful power-up sequence, the DAT enters the bit
monitoring mode.
Power Save Timeout (PST) Parameter
The power save timeout turns off the DAT display after keypad
activity has stopped for a user-defined period of time. The power-save
(DAT:0.PST) value is set in the DAT Function File. The valid range is 0
to 255 minutes. The power-save feature can be disabled by setting the
PST value to 0, which keeps the display on continuously. The default
value is 0.
In power-save mode, a dash flashes in the left-most segment of the
display. Press any key (except F1 or F2) to return the DAT to its
previous mode. If F1 or F2 is pressed, the DAT will change the value
of the F1 or F2 status bits, but the display remains in power-save
mode.
