the controller mode switch and the Power-Up Mode Behavior Selection
bit (S:1/12).

Load Memory Module Always
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 is
set in the memory module and power is applied, the controller
downloads the memory module program.
The mode of the controller after the transfer takes place is determined by
the controller mode switch and the Power-Up Mode Behavior Selection
bit (S:1/12).

Power-Up Mode Behavior
If Power-Up Mode Behavior is clear (0 = Last State), the mode at
power-up is dependent upon the:
• position of the mode switch
• state of the Major Error Halted flag (S:1/13)
• mode at the previous power down
If Power Up Mode Behavior is set (1 = Run), the mode at power-up is
dependent upon the:
• position of the mode switch
• state of the Major Error Halted flag (S:1/13)
Address Data Format Range Type User Program Access
S:1/11 binary 0 or 1 control read only
Address Data Format Range Type User Program Access
S:1/12 binary 0 or 1 control read only
IMPORTANT
If you want the controller to power-up and enter the Run mode, regardless
of any previous fault conditions, you must also set the Fault Override bit
(S:1/8) so that the Major Error Halted flag is cleared before determining the
power up mode.
