SECURITY

There are five levels of security access on EMCP 4: LEVEL 0, LEVEL 1, LEVEL 2, LEVEL

3, and SERVICE TOOL. Any configurable parameter or function that is set to Level 0 can be accessed by anyone at any time, and 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 Cat DEALER TC 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 Cat Service Tool is required in order to perform the desired function; or the setpoint may be read only and cannot be changed.

All of the adjustable parameters are associated with a specific level of security required to make an adjustment to the parameter. Certain functions, such as resetting the number of crank attempts, are also associated with a specific level of security. The passwords only affect actions taken at the EMCP 4. Access of the EMCP 4 remotely via the Cat Service Tool or via the SCADA data link is not affected by the security level on the EMCP 4 display.

Changing parameters with the Cat 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 EMCP 4.

However, the passwords themselves may differ. Furthermore, the EMCP 4 and the SCADA data link may be at different levels of access at any given time. For more information about SCADA security see Chapter 18.

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 will be able to be changed by anyone at any time.

Note: The EMCP 4 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 EMCP 4 will start at Level 0 on power up. When the Level 1 password is entered, the EMCP 4 will move up to Level 2 access.

THE SECURITY MENU

To get to the security menu:

At MAIN MENU scroll DOWN to Configure Press the OKKEY .

At SECURITY,press the OKKEY .

The SECURITY MENU will show the current level of security at the top of the screen.

There are six options on the security menu:

DROP TO MIN LEVEL CHANGE LVL 1 PSWD

ENTER LEVEL 1 or 2 CHANGE LVL 2 PSWD

ENTER LEVEL 3 CHANGE SCADA PSWD

Selecting DROPTOMINLEVEL will make the control go to the minimum level of

security. As previously discussed, if the level 1 and level 2 passwords are not defined by the user, the minimum level of security will be level 2. If a level 2 password is defined by the user, but not a level 1 password, then the minimum level of security will be level 1.

In contrast, if a level 1 password is defined by the user, but not a level 2 password, then the minimum level of security will be level 0.

Selecting ENTERLEVEL1 OR 2 will open up a password entry screen.

The password entry screen will have 4 spaces. In each space a numbers from 0 through 9 can be entered. The password can be from 1 to 4 digits and is entirely user defined. Enter the password for either level 1 or level 2 if either of those passwords have been defined. Use the UP ARROW or DOWN ARROW to change the value of any highlighted digit. Use the

LEFT ARROW or RIGHT ARROW to navigate between digits.

Selecting ENTERLEVEL3 will cause the display to say “PHONE IN WITH” and a 16 digit number will be displayed. Under that, ENTER RESPONSE will be highlighted. Record the 16 digit number and call the Cat Dealer TC with this number. The TC will reply with another 16 digit number.

Press the OKKEY from the PHONE IN WITH

screen, and a password entry screen will be

displayed. Enter the password that was supplied by the TC in the same manner as the other types of passwords.

Press the OKKEY to confirm, or ESCAPE KEY to reject the change. Pressing the OK KEY after entering the number will set the current level to 3. The control will remain in level 3 security level until no key presses have been made for 10 minutes. After 10 minutes of inactivity the control will revert back to the minimum level of security.

Note: To change a level 3 parameter requires either a level 3 password from the TC or a PC connection using a Service Tool. Therefore, if you have a Service Tool, try to change the parameter using the Service Tool rather than calling the TC.

Selecting CHANGELVL1PSWD will allow for the level 1 password to be changed. The control must be at level 1 security in order to select CHANGE LVL 1 PSWD. The CHANGE LVL 1 PSWD screen looks just like the password entry screen. It has 4 blank spaces that can each be set to a number from 0 to 9. The password can use as few as one digit and can use as many as 4 digits. It is entirely up to the user. If a password has been set but, it is now desired to not have level 1 password protection, the level 1 password can be disabled by setting the password to be a single 0.

Once the desired password is entered, press the OKKEY and the control will go

Selecting CHANGELVL2PSWD will allow for the level 2 password to be changed.

The control must be at level 2 security in order to select CHANGE LVL 2 PSWD. The

CHANGE LVL 2 PSWD screen looks just like the password entry screen. It has 4 blank spaces that can each be set to a number from 0 to 9. Selecting a password is entirely up to the user and can use as few as one digit or as many as 4 digits.

The level 2 password can be disabled by setting the password to be a single 0.

Once the desired password is entered, press the OKKEY and the control will go back to the SECURITY SCREEN and the level 2 password will be set.

Selecting CHANGESCADAPSWD will allow for the SCADA password to be changed.

This password, if ENABLED, will require a SCADA system to first enter the password into the WRITE ACCESS PASSWORD register prior to conducting any other reads and writes.

The control must be at level 2 security in order to select CHANGE SCADA PSWD. The

CHANGE SCADA PSWD screen looks just like the password entry screen. It has 8 blank spaces that can each be set to a number from 0 to 9. The password can use as few as one digit and can use as many as 8 digits.

Just as with level 1 and level 2 passwords, entering a single 0 will DISABLE the SCADA password.
