Maintaining Passwords through a Power Cycle
Initial passwords are blank for a new controller or a controller that has its passwords cleared. For
passwords to be maintained through power cycles, the controller must either:
Store to RAM and use an Energy Pack or battery to maintain memory.
Store to User Flash with configuration set up to load from Flash at power up.
Disabling Passwords
The use of password protection is optional. Passwords can be disabled using the programming software.
Note: To enable passwords after they have been disabled, the CPU must be power cycled with the
battery or Energy Pack removed.
