1 System administrator roles and responsibilities 1 The Entellisys™ Low Voltage Switchgear system requires a System Administrator for oversight of critical functions. Those critical functions are described in this guide. Chapter 1 provides an overview of the roles and responsibilities. The following chapters describe how to perform the functions, in detail. 1.1 Security Champion The most important role of the System Administrator is to control the access to the system.
1 8 System administrator roles and responsibilities
2 Pre-programming settings prior to switchgear arrival 2 Entellisys provides a method for users to work on the system settings before the switchgear arrives. Once the gear is installed and control power is applied, the saved settings can be written to the system. To pre-program Settings, the “Entellisys Remote HMI – User Interactive version” must be purchased. GE will ship the Remote HMI software, System Administrator Manual (this manual), and a System Archive when the switchgear ships from the factory.

4 Passwords 4.1 HMI permissions and passwords The Entellisys HMI requires a login name and password. This login sets the permissible actions for the session. Each user's permissions are programmable to provide flexibility. Only the Administrator can set permissions, login names, and passwords. 4 CAUTION: Enabling Group Permissions for features that allow the changing of settings and/or access to control functions must be restricted to accounts for qualified personnel only.
Once Groups are established, individual Users can be created. Users can have individual login names and passwords. Passwords consist of 3-20 alphanumeric characters. Both login names and passwords are case-insensitive. NOTE: There are three predefined Groups that cannot be modified. Beneath those Groups are two Users that are fixed and cannot be modified. The passwords for all can be changed.
To change a password 1. On the Main Menu, click the User Administration button. Only Administrators can access User Administration. For all others, the button will not appear on the Main Menu. 2. Select the desired user group on the left-side pane. Expand the group by clicking the + symbol and click a user name. 3. Enter the new password in the New Password field. 4. Confirm your password by re-entering the new password in the Confirm Password field.
4.2 Modbus® security 4.2.1 Control and settings passwords The CPUs require extra passwords to change settings (i.e., Short Time pickup delay setting) and to send commands (i.e., Open Breaker command). These passwords apply to all clients that access the Entellisys system through Modbus communications including the Entellisys HMI, SCADA, or Building Automation, etc. 4 NOTE: The system ships with default CPU Modbus Settings and Command passwords.
To change the Settings and/or Command passwords 1. On the Main Menu, click the Maintenance button. The button will only be displayed if access is allowed with the current login permissions. 2. Click the Modbus Security tab. The Modbus Security screen has options to change both CPU A and CPU B Command and Settings passwords. NOTE: It is recommended that the passwords in CPU A and CPU B be set to the same value. 4 3. Enter the new commands password in the New Password field. 4.
Figure 4-6 Breaker Control screen 4 • The CPU reserves a communication port for the HMI with the Local HMI flag set. The CPUs can support up to 8 simultaneous communication ports for Modbus clients. Once the limit is exceeded, clients will be blocked until a port is free. The Local HMI flag has special ports reserved for its use to prevent other clients from locking it out. NOTE: All In-Gear and Near-Gear Touchscreen HMIs should have the “Local HMI” set. To set an HMI as a local HMI 1.
5 Time synchronization In the Entellisys System, time is recorded when events occur for diagnostic purposes. Events are generated from both the HMI and the CPU components and the time stamps used are derived from time set in the component. One HMI in the system will be configured to synchronize time with the CPUs. Periodically, the HMI will synchronize time to ensure the time in the two CPUs is consistent. 5 Time synchronization configuration is done by GE during the system start up.
