1. Unlock CPU e AUX 83 Lock CPU AUX 81 Modify Password You can use AUX 81 to provide an extra measure of protection by entering a password that prevents unauthorized machine operations The password must be an eight character numeric 0 9 code Once you ve entered a password you can remove it by entering all zeros 00000000 This is the default from the factory Once you ve entered a password you can lock the CPU against access There are two ways to lock the CPU with the Handheld Programmer e The CPU is always locked after a power cycle if a password is present e You can use AUX 82 and AUX 83 to lock and unlock the CPU DL05 Micro PLC User Manual 6th Edition Rev C A 9 Appendix A Auxiliary Functions A You can also enter or modify a password from within DirectSOFT 5 by using the PLC Password sub menu This feature works slightly differently in DirectSOFT 5 Once youve entered a password the CPU is automatically locked when you exit the software package It will also be locked if the CPU is power cycled WARNING Make sure you remember the password before you lock the CPU Once the CPU is locked you cannot view change or erase the password If you do not remember the password you have to return the CPU to the factory for password removal It is the policy of AutomationDirect to clear the PLC memory which includes the password and the program NOTE The DLO5 CPUs support multi level password protection of2.
