14 Administrator access to the operating system

6 Contents

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.

There are several forms of access:

???HMI Login Access: Entellisys provides programmable permissions and passwords. The System Administrator determines who needs what permissions and assigns login names and passwords.

???Modbus?? Settings and Control Access.

???Remote Access to the Switchgear over a company network.

Security Reminders

???Limit the access level handed out to only the required permissions.

???Stress the importance of keeping passwords secret.

???If you believe passwords have been compromised, change them immediately.

???Always log out before leaving the local HMI, or leave the system logged in as Guest. Alternatively, the switchgear can be configured to automatically log out after a time period. (For details, on the Main Menu, click User Settings, and then click HMI Preferences.)

1.1.1System Maintenance

The System Administrator is also responsible for system maintenance as described in this document.

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.

The following steps should be performed to begin pre-programming:

???Step 1: Install the ???Entellisys Remote HMI ??? User Interactive version??? software. See Installing and configuring remote HMI software on page 25 for instructions.

???Step 2: Install the System Archive provided by GE. See Restoring an archive on page 38 for instructions.

???Step 3: Change to Offline Mode.

See Offline mode on page 29 for instructions and for offline mode capabilities.

???Step 4: Set User Settings.

See DEH-231 Entellisys Low Voltage Switchgear System User Manual.

???Step 5: Install and Commission the Switchgear.

See Commissioning the switchgear on page 11 for instructions.

???Step 6: Configure the System for Remote Communications.

See Configuring the switchgear for remote communications on page 21 for instructions.

???Step 7: Write saved Settings to System.

See Writing settings to a live system on page 33 for instructions.

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 the4 Administrator can set permissions, login names, and passwords.

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. As a reminder, users with such privileges will be presented with the following screen upon initial login:

Figure 4-1 Initial login Caution screen

4.1.1 Setting HMI login permissions and passwords

A Group defines the permission categories for a type or group of users. By default,

Administrator, Operator, and Guest groups are defined with preset permissions as examples.

Additional groups may be created with programmable permissions.

Figure 4-2 Programmable permissions screen

Figure 4-3 User Administration screen in the HMI

To set permissions for a user Group

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.Click the desired user group to edit or click the Add Group button to define a new type of user.

3.Change the permissions by selecting the appropriate check boxes in the permission list.

???User will be granted this permission.

???User will not have this permission.

4.Change the permissions by selecting the appropriate check boxes in the permission list.

4.Click Go. If successful, the Main Menu will display.

4.1.2Resetting forgotten HMI passwords

Administrators have access permission to change passwords for all users in all groups.

NOTE: It is very important for the System Administrator to keep the Administrator password in a safe location. Losing the Administrator password will require a GE Field Service visit to reset it.

GE offers an optional service to store the Administrator password at the request of customers. In the event the password is lost, GE can provide the password to the customer over the phone, without requiring a site visit.

Contact GE Post Sales Service for help (see How to contact us on page 2).

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 4to 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.

NOTE: The system ships with default CPU Modbus Settings and Command passwords. The

System Administrator should change these passwords for added security.

The HMI can be configured to transparently send the passwords whenever needed or it can be configured to require all users to re-enter the password when the action is attempted.

Figure 4-5 Modbus Security screen in the HMI

16 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.Re-enter the password in the Confirm Password field.

5.Click the Change button to download the password.

6.Select the desired Auto Send option.

???Indicates the Auto Send option will transparently send the password each time a command is sent to the CPU.

???Disables the Auto Send option.The user will be prompted to enter the password (for the CPU that is currently the default) each time a command is sent.

NOTE: For added security, it is recommended the Auto Send option be disabled. This will require an additional password to be entered each time a command is performed.

4.2.2 Local HMI

An Entellisys system may have multiple HMI stations running. There are some functions that should be performed by one HMI only. The ???Local HMI??? flag is provided to designate one HMI for special functions.

The ???Local HMI??? flag affects the following functions:

???E-mail on Alarms is only sent from the HMI with the Local HMI flag set.

???Time Synchronization is only performed by the HMI with the Local HMI flag is set.

??????Block other HMIs??? can be enabled/disabled only by the HMI with the Local HMI flag set. This allows a user on the Local HMI to block all other HMIs from issuing control commands (i.e., Breaker Open), which may be desired during maintenance. For details on circuit breaker control, see DEH-231 Entellisys Low Voltage Switchgear System User Manual, Chapter 3, Basic Control.

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.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.

3.Select the Local HMI check box as shown in Figure 4-5.

4.Click the OK button to save changes (or click Cancel to cancel changes).

18 Passwords

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.

NOTE: The System Administrator should periodically check the date and time set on all local HMIs to ensure the event time stamps are accurate. It is especially important on the HMI configured to time synch the CPUs.

5.0.1 Setting time in the HMI

To set time, log into the HMI Operating System with Administrator access (see Administrator access to the operating system on page 61.) Double-click the Clock icon on the taskbar to set date, time, and time zone. Restart the computer to revert to normal run mode with limited OS access.

6 Configuring the switchgear for remote communications

The following is recommended to Configure the Entellisys Low Voltage Switchgear System for remote communications:

Step 1: Acquire static IP addresses compatible on the company network.

NOTE: Entellisys components are not DHCP-compatible.

6

The number of IP addresses required depends on the number of HMIs. The following number of IP addresses is required:

???CPU A

???CPU B

???All In-Gear HMIs

???All Near-Gear HMIs

???All Remote HMIs

NOTE: Additional IP addresses might be required to configure a VPN/firewall appliance if one is installed.

The subnet mask must be compatible with the network segment on which each device resides. Gateway IP depends on the company network and needs to be acquired from the Network Administrator.

Step 2: Reset the CPU IP Addresses.

See Setting IP addresses for remote communication on page 22.

Step 3: Reset the local HMI IP Addresses.

See Setting IP addresses for remote communication on page 22.

Step 4: Verify communication between the local HMIs and CPUs.

See Setting IP addresses for remote communication on page 22.

Step 5: Install and Configure a network security device such as a VPN/Firewall appliance. See Network security/VPN device on page 24.

Step 6: Connect the Entellisys system to the company network via the VPN/Firewall appliance in the switchgear.

Step 7: Verify communication between local HMI(s) and CPUs.

See Setting IP addresses for remote communication on page 22.

21

Step 8: Install Remote HMIs.

See Installing and configuring remote HMI software on page 25.

Step 9: Verify communication between Remote HMI and CPUs.

See Chapter 5.2. [dk: there is no section 5.2?]

6.1 Setting IP addresses for remote communication

To change the HMI IP address

1.For the HMI touchscreen computer, login to the Operating System as Administrator. See Administrator access to the operating system on page 61 for details.

2.Open the Control Panel, and then open the Network Connections dialog box.

3.Double-click the Local Area Connection 1.

4.In the TCP/IP Properties tab, set the new Local HMI IP address. Set the subnet mask to a value compatible with the segment on which it resides.

By default the subnet mask is set to 255.255.255.0. The default touchscreen HMI IP address is 192.168.1.1 as delivered. The default IP address for each additional touchscreen HMI is incremented by 1 in the right-most address.

6.1.2 CPU IP address

To change the CPU IP addresses

1.On the Main Menu, click User Settings.

2.Click HMI Preferences.

3.Click Communication.

4.Select either CPU A or CPU B by clicking the appropriate button.

5.Enter the new IP address. The IP address format is X.X.X.X where X is from 0 to 255.

22 Configuring the switchgear for remote communications

Figure 6-1 Set CPU IP Addresses screen

6

6.Click the Test Communication button to verify the communication status with the new IP address. It will take a few seconds to establish communication with the CPU.

7.In unable to connect, a dialog box will display. Click the Retry button to test communication again or click Cancel to exit.

8.The Communication status with the new IP address will display below the IP address edit dialog box.

For example:

???CPU A: System Running OK??? ??? Communication with new IP address is success.

???CPU B: System Unavailable??? ??? Failed to communicate with new IP address.

6.2 Network security/VPN device

NOTE: GE recommends that your Entellisys Low Voltage Switchgear system be equipped with a VPN/Firewall device if it is connected to a LAN that is also used for other purposes. Failure to do so could result in unauthorized access to the control and settings functions of the circuit breakers.

In addition to the standard username and password administrative functions for Entellisys, accessibility to control functions and parameter settings must be considered from the network point of view. The provisions for securing the network on which Entellisys communicates to HMI

6Control Stations and other SCADA systems depends greatly on how the network over which they communicate is configured.

???In-Gear HMI only ??? In this configuration, there is no network access external to the switchgear and therefore no implications for network security.

???In-Gear and Near-Gear HMIs ??? The implications for network security depend on the accessibility of the network the Near-Gear HMI uses to reach the main switchgear instrumentation compartment.

???In-Gear, Near-Gear, Remote HMIs, and SCADA system access ??? The implications for network security depend on the accessibility of the network the Near-Gear HMI uses to reach the main switchgear assembly.

GE provides a mechanical mounting assembly compatible with Juniper Networks NetScreen- 5GT VPN/Firewall Appliance. Since configuration of the device is mostly dependent on the specific network architecture of the facility in which it is installed, please consult the NetScreen documentation for assistance in configuring this device, or contact your local IT department or network service provider.

As a minimum, GE recommends that the VPN/Firewall appliance be configured to only permit communications between the devices in the switchgear instrument compartment and the external devices that are intended to communicate with them.

Contact GE Post Sales Service for the latest VPN/Firewall appliance application guide. See How to contact us on page 2.

24 Configuring the switchgear for remote communications

7 Installing and configuring remote HMI software

Entellisys Remote HMI software allows users to access the switchgear system from any desktop computer.

There are two versions of Remote HMI software:

???User Interactive version: provides programmable permission levels for all users from full ???Administrator??? access to view-only ???Guest??? privileges.

???Viewer version: limited to view-only ???Guest??? privileges. Login name and passwords are fixed.

Step 2: Install and launch the HMI program

Insert the ???Entellisys Remote HMI??? CD and run the install program. Follow the onscreen installation wizard. Click Finish to complete the installation.

To start the Entellisys Remote HMI application, point to Start, select Programs, and then double-click Entellisys LVS HMI.

Step 3: Activate the software with a code from GE

The first time the Remote HMI program is launched, a window will display requesting an

Activation code.

26 Installing and configuring remote HMI software

Step 4: Login

Enter a valid login name and password (case insensitive).

NOTE: You must enter the default login names and passwords, since at this point in the installation the programmable permissions and passwords have not been assigned.

If successful, the Main Menu will display.

7

NOTE: The System Administrator must reassign these default passwords as soon as possible to maintain controlled access.

Step 5: Set IP addresses, verify system communication

See HMI IP address on page 22.

NOTE: Once this step is performed, the Remote HMI is communicating with the live system. You must complete the next step to get the proper screens and configuration.

Step 6: Update HMI with Shared Files

During the Remote HMI installation, generic files are loaded. The custom system files corresponding to a particular system must be obtained for proper screens and configuration. Otherwise blank oneline, elevation, and control panel screens will be shown, the advanced protection configuration and zone settings will not be shown, and other maintenance configuration will not be set.

Entellisys provides a way for the System Administrator to easily distribute these files from a properly configured HMI to other HMIs.

See Viewing and comparing settings files on page 31 for details.

NOTE: When installing a Remote HMI prior to the switchgear arrival, this step cannot be performed. In this situation, a System Archive must be installed. See Restoring an archive on page 38 for instructions.

28 Installing and configuring remote HMI software

8 Settings files and offline system configuration

All system settings are recorded locally in ???Settings??? files. These files are updated each time a setting is modified and automatically updated every 30 minutes.

NOTE: Both CPUs must have the same configuration and settings at all times, otherwise unpredictable system behavior could occur. Every 30 minutes the system compares the settings between the CPUs. If a mismatch in settings between CPUs does occur, an event will be generated. A mismatch should be correctly immediately.

The HMI has a special offline mode. Offline mode disconnects the HMI from a live system and allows users to modify and save settings. Later, once reconnected to a live system, these saved settings can be written to the system.

The following operations are permitted in offline mode:

???User Settings activities

???Maintenance activities

???User Administration

Another convenience offline mode provides is the ability to work on protection settings prior to the arrival of the switchgear. See Commissioning the switchgear on page 11 for more details.

To enable or disable offline mode

1.On the Main Menu, click the Maintenance button. The button will only display if Maintenance access is allowed with the current login permissions.

2.On the Maintenance screen, click the Settings File tab.

3.Select the Work Offline check box to change to offline mode. This can be found in the lower right-hand corner in Figure X (chapter 2.1). [dk: no section 2.1?]

???HMI will go into offline mode and disconnect from the live system.

???HMI will connect to the live system.

An icon on the bottom-right screen displays to indicate that the application is in offline mode.

Figure 8-2 Offline mode icon

The first time offline mode is enabled, a new set of settings files will be created as follows:

Offline(ELVS_A).fbs and Offline(ELVS_B).fbs.

30 Settings files and offline system configuration

4.Click Load to ensure the desired files are loaded for offline work. If the Load button is grayed out, the highlighted file is already loaded.

NOTE: If the state of the offline settings files is unknown, it is recommended to reset the offline

settings files to the current settings. See Chapter 2.4. [dk: there is no section 2.4?]

Changes made during offline mode

???User Settings and Maintenance changes are automatically saved to the active settings file loaded.

???User Administration changes can be viewed under User Administration only.

10 System archives

A System Archive is a snapshot of the system's custom screens, configuration, and optionally the event logs, fault reports, and waveforms. The archive is used to reconfigure a system, putting it back to a known state. It is important to have a valid System Archive at all times.

An archive is created and shipped to the System Administrator when the switchgear ships from the factory. The archive may be installed in a Remote HMI application allowing users to pre- program protection settings prior to the switchgear arrival.

Archives are recommended at the following events:

???At switchgear startup, once the system settings have been programmed and tested.

???Periodically throughout the life of the switchgear ??? for example prior to summer shutdown each year.
