Fault Override At Power-Up
When set (1), causes the controller to clear the Major Error Halted bit (S:1/
13) at power-up. The power-up mode is determined by the controller
mode switch and the Power-Up Mode Behavior Selection bit (S:1/12).
See also:FO - Fault Override on page 61.
Startup Protection Fault
When set (1) and the controller powers up in the RUN or REM RUN
mode, the controller executes the User Fault Routine prior to the
execution of the first scan of your program. You have the option of
clearing the Major Error Halted bit (S:1/13) to resume operation. If the
User Fault Routine does not clear bit S:1/13, the controller faults and does
not enter an executing mode. Program the User Fault Routine logic
accordingly.
Load Memory Module On Error Or Default Program
For this option to work, you must set (1) this bit in the control program
before downloading the program to a memory module. When this bit it
set in the memory module and power is applied, the controller
downloads the memory module program when the control program is
corrupt or a default program exists in the controller
.
