Aux 82 Unlock Cpu; Aux 83 Lock Cpu - Automation Direct DL05 User Manual

Appendix A: Auxiliary Functions
You can also enter or modify a password from within DirectSOFT 5 by using the
A
PLC/Password sub-menu. This feature works slightly differently in DirectSOFT 5. Once
you've entered a password, the CPU is automatically locked when you exit the software
2
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
3
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.
4
NOTE: The DL05 CPUs support multi-level password protection of the ladder program. This allows
5
password protection while not locking the communication port to an operator interface. The multi-level
password can be invoked by creating a password with an upper case "A" followed by seven numeric characters
(e.g. A1234567).

AUX 82 Unlock CPU

7
AUX 82 can be used to unlock a CPU that has been password protected. DirectSOFT 5 will
automatically ask you to enter the password if you attempt to communicate with a CPU that
8
contains a password.

AUX 83 Lock CPU

9
AUX 83 can be used to lock a CPU that contains a password. Once the CPU is locked, you
will have to enter a password to gain access. Remember, this is not necessary with
DirectSOFT 5 since the CPU is automatically locked whenever you exit the software package.
