SPRING 1956947 - Caterpillar

Security
The OCP has five levels of security access:
"LEVEL 0"
"LEVEL 1"
"LEVEL 2"
"LEVEL 3"
"SERVICE TOOL" Any configurable parameter or function that is set to "LEVEL 0" can be accessed by anyone at any time. There will never be any security information on the display screen."LEVEL 1" access and "LEVEL 2" access represent increasing levels of access to the setpoints and functions of the controller. Both levels 1 and 2 can be password protected with separate user-defined passwords.Note: These are optional levels of security, by default these passwords are disabled, and the default access level is "LEVEL 2" from parts service."LEVEL 3" access is password protected at the factory, and requires contacting the technical communicator at the Caterpillar Dealer to obtain a password. If the present security level of the controller is below the level needed to perform a desired function, a padlock and a number will be displayed at the bottom right-hand corner of the display. The number represents the level of security that is required in order to perform the desired function 1, 2, or 3.If there is a padlock but no number, then the Caterpillar service tool is required in order to perform the desired function. The set point may be read only and cannot be changed.All of the adjustable parameters are associated with a specific level of security required to adjust the parameter. Certain functions, such as resetting the number of crank attempts, are also associated with a specific level of security. The passwords only effect actions taken at the OCP. Access of the OCP remotely via the Caterpillar service tool or via the SCADA data link is not affected by the security level on the OCP display. Changing parameters with the Caterpillar service tool does not require passwords, since the service tool already has the highest level of access.When connecting via the SCADA data link, passwords can also be used. The levels of access granted via SCADA are identical to the levels of access granted at the OCP. However, the passwords may be different. Furthermore, the OCP and the SCADA data link may be at different levels of access at any given time.Level 1 and Level 2 passwords are usually "DISABLED" when shipped from the factory. Level 1 and Level 2 passwords can be user-defined if desired. If the Level 1 and Level 2 passwords are not user-defined, the Level 2 will be the "MINIMUM LEVEL". All parameters that require Level 0, Level 1, or Level 2 security can be changed by anyone at any time. Note: The OCP will always move up in security level to the highest level of access that is not password protected when a certain level of access is requested. For example, if a Level 1 password has been defined, but a Level 2 password has not, the OCP will start at Level 0 on power up. When the Level 1 password is entered, the OCP will move up to Level 2 access.The Security Menu
