4. EXTERNAL OPERATOR PROGRAM (HMI500)

4.1. Introduction

HMI500 is the human/machine interface (HMI) for the protection systems REB500 and REB500sys. For brevity, these Operating Instructions refer simply to REB500 although the program applies to both systems. There are additional menu items, which only apply to REB500sys, and attention is explicitly drawn to these.

HMI500 is a convenient human-machine interface which permits the operator to view REB500 measurements and statuses, set REB500 protection functions and configure the system, download the latter data to REB500 and to control the disturbance recorder and event memory integrated in the system.

HMI500 runs on a standard PC (see Section 4.3.1. “Minimum PC requirements”) under Windows 98, Windows NT, Windows 2000 and Windows XP.

The data are transferred between the PC and REB500 via an optical reader attached to the front of either central or bay units and coupled to a serial interface on the PC.

NOTE: Any changes (e.g. settings, configuration etc.) made using HMI500 are stored in a specific customer database (MDB file) in the PC and not in the protection system. The database then has to be downloaded from the PC to the protection system (see Section 4.5.1.4.).

4-3


4.2. Safety instructions

DANGER: HMI500 permits circuit-breakers and isolators to be operated. Every program operation and the possible consequences must be considered carefully beforehand. If switching operations have to be carried out, the same precautions must be taken as when performing them manually.

WARNING: Earlier HMI500 versions are incompatible with Version 7.30 of the protection system software.

WARNING: A password has to be entered to operate HMI500. Passwords may only be assigned to authorized operators. Change the standard passwords in the software as soon as the program is installed.

4-4


4.3. Installation

The human-machine interface program HMI500 Version 7.40 is supplied on an installation CD in German, English, French and Spanish.

4.3.1. Minimum PC requirements

HMI500 runs on an IBM PC, compatible under Microsoft. Observe the information published by Microsoft on the PC hardware requirements in relation to the operating system installed.

The minimum PC hardware performance requirements are as follows:

• PC with a CPU operating at 300 MHz or higher

• mouse plus PS/2 interface (bus board) if the PC has only one serial interface

• 16 MByte RAM (64 MByte recommended) for Windows 98 and Windows NT 4.0; at least 64 MByte for Windows 2000 or Windows XP (256 MByte recommended)

• CD-ROM or DVD-ROM drive

• 1 serial interface (RS-232C) (COM1 or COM2)

• SVGA monitor (800 x 600)

• 1 parallel interface (LPT1) for a printer (recommended).

NOTE: The PC-operating program HMI500 runs under Microsoft®

Windows98® 1st Edition with Internet Explorer 4 SP2 or 2nd edition

Windows NT® V4.00 Service Pack 5

Windows 2000® Service Pack 4

Windows XP®

4.3.2. Set-up

Administrator access rights are required for the installation of HMI500 on PCs running the operating systems Windows NT, Windows 2000 or Windows XP. An attempt to install the program with lower access rights prompts an error message and the installation is aborted. Contact your system administrator in this case.

4-5


Insert the CD-ROM in the drive. The installation program is then started automatically1.

Select the preferred language and confirm that the installation procedure should be continued.

You are now requested to read and confirm your acceptance of the license conditions.

The installation program proposes a target directory. Either confirm the proposed directory or enter a desired one. The program is installed automatically in the prescribed directory after clicking on “Next>”

1 Should the auto-start function on your PC be disabled, select and run the

program start.bat on the CD to start the installation program.

4-6


A HMI500 directory and program icon 'HMI500 x.xx ss' are created in the Windows Start menu, x.xx signifying the program version and ss the language.

4.3.2.1. Communication interface, off-line and simulation mode

By default, the installation routine will select the first free inter-face (COM port). The communication settings can be changed subsequently by selecting 'Tools / Settings' (see Section 4.5.6.5.).

Aside from the interface a connection via TCP/IP is available as communication path.

The same menu item also provides a choice of operating mode by selecting either the radio button 'Off-line' (excludes the functions requiring a REB500 to be connected) or 'Simulated' (no REB500 connected, but with all the functions available for demonstration purposes and random generation of data) (see Section 4.5.6.5.).

NOTE: HMI500 automatically starts off-line, if an invalid COM port is entered or another application is using the port.

4-7


4.3.2.2. Mouse

A mouse is necessary to work with the HMI500 efficiently. It is possible to control it solely via the keyboard, but this can be a little cumbersome. The right mouse button is also used for some operations, and therefore it should not be configured to perform other functions (e.g. double click).

4.3.2.3. Installation on a network

Before attempting to install HMI500 on a network, ascertain that you are authorized to write in the corresponding Windows directory, otherwise the installation will fail.

4-8


4-9

4.4. Starting HMI500

NOTE: The program screens in this section are based on a typical application. Depending on the power system configura-tion and the options configured while engineering your system, certain menus may be missing or the display appears different.

The first screen to appear after starting the operator program is the 'System log-on' dialog:

Fig. 4.1 System log-on dialog

The program can be run in a read only mode by appropriately activating the 'Read only' check box, i.e. the data can be viewed but not changed. Users that want to run the program in a read/write mode (check box deactivated) must enter a password.

NOTE: To enable a start to be made, the password is set to 'System' when the program is supplied (case sensitive!).

HMI500 obtains the specific device data from a database in a file, which is stored both in the PC and the protection system. Database files on the PC have the extension '.mdb'.


4-10

Click on the 'OK' button to continue the start-up routine or on the 'Cancel' button to discontinue and close the program.

Communication with the protection system is tested after clicking on 'OK'.

Providing communication can be established, HMI500 starts in the on-line mode.

Should communication with the protection system fail, it starts either off-line or in the simulation mode (see Section 4.5.6.5.).

The main HMI500 window then appears.

Some of the dialogues used by the program are standard Windows dialogues. Should these not be in the same language as HMI500, than a different language is set for the Windows operating system.

NOTE: The database that was open during the last session opens automatically. If no database was open before, select 'Open' in the 'File' menu and then the desired file. An error message is displayed if an attempt is made to open an incompatible file. An existing file in the protection system can also be opened using the 'Upload' function in the 'File' menu.


4-11

The menu item 'File' permits databases to be opened and saved and a database to be uploaded from the protection or downloaded to it.

4-12


View

The menu item 'View' contains menu items for viewing the plant diagram, the measurements of each protection zone, inputs and outputs, switchgear statuses, the event list and any tripping that has taken place. For REB500sys, the application also provides facility for viewing the bay protection measurements.

Settings

By selecting the menu item 'Settings' it is possible to set the system parameters, the operating values for the various protection functions and the communication parameters.

Configuration

The menu item 'Configuration' concerns the definition of the various circuit-breakers, isolators and CTs, the activation/ deactivation (masking/unmasking) of items of plant, the configuration of system modules, tripping logics and the disturbance recorder and maintenance instances presented. Other items configured are the LEDs on the local HMI (REB500sys, bay unit type 500BU03) and the optional GPS synchronization system. In the case of REB500sys, an overview of the licensed bay protection functions is also provided.

Testing

The menu item 'Test' is for enabling/disabling either the test or installation mode.

Tools

Functions for editing data file versions, producing reports, exporting SCS communication data, changing passwords, selecting operator program options and setting the system time are available under the menu item 'Tools'.

Help

The online help system and information details of the software version are accessed by clicking on “Help”.

Status information is displayed on the bar at the bottom of the main window (Simulation/On-line/Off-line, Edit/Read only, Test mode, Installation mode, Database version, Setfile). These have the following significance:

Fig. 4.5 Status bar

4-13


On-line/Off-line

If the program can successfully establish contact with the protection system, it is in the on-line mode. If no connection can be established or is not desired the program is in the off-line mode.

Simulation

The system is in the simulation mode when 'Simulation' is displayed on the status bar. All the functions can be executed without being connected to a protection device. Random values are generated when viewing protection unit data, e.g. event lists or measurements. Simulated faults can also be viewed.

Edit/Read only

'Edit' permits settings to be saved in a file or downloaded to the protection system. In the 'Read only' mode it is only possible to read data.

Fig. 4.6 Upload from protection system

4.5.1.4. File / Download to protection system

Open the 'File' menu and select 'Download to protection system' to download the current data from the PC database to the protection system.

The versions are compared before downloading proceeds and the result is displayed. An index and a comment may also be entered beforehand by selecting Tools/Version (see Section 4.5.6.). For safety reasons, the new data is only saved if it is different. Data will only be saved if they are different or the version index is different.

4-15


NOTE: Data can be correctly downloaded as soon as the central unit has started.

After the downloading procedure is complete, the protection system is restarted and the valid version can then be verified on the HMI.

Fig. 4.7 Download to protection system and comparison of versions

Fig. 4.8 Warning: Download to protection system and comparison of versions

The progress of the downloading procedure is shown on the screen. The correct time format must be set via the control panel on the PC for the procedure to be presented correctly. The procedure can be interrupted by the user as far as 'Archive data in the protection system'.

4-16


Fig. 4.9 Download to protection system

Various check sums are calculated to establish the integrity of the data in the database and these are examined after the transfer of data has been completed.

Only after all the data have been successfully transferred are they saved in the non-volatile memory. The auxiliary supply of the central unit must not be interrupted during this part of the procedure.

4.5.1.5. File / Compare…

This menu item provides facility for comparing the PC database loaded by HMI500 and the database stored in the protection system or a second database file in the PC.

4-17

Second database is stored at PC

Activating this radio button compares the system database loaded by HMI500 and another database in the PC. The latter is chosen by clicking on the button 'Select file…'.

Second database is at target

Activating this radio button compares the system database loaded by HMI500 and the database already stored in the protection system. The degree of detail is determined with the aid of the button 'Only compare checksum'.

Show only differences

Checking the 'Show only differences' box enables the scope of the report to be limited to the differences actually found.

Limit number of differences

The number entered here determines the number of differences that can be found before the current comparison operation is aborted.

4-18


Show pre-engineering changes only for feeders, modules and switchgear objects

When this box is checked (default setting), the comparison is restricted to determining whether changes have taken place in relation to the pre-engineering data for bays, modules and switchgear. Generally, the default settings should be retained as otherwise the number of differences that will be discovered increases considerably (events, signals etc., are then also taken into account).

Write log file

Check the box 'Write log file' to store the results of the comparison in a file.

Compare…

The button 'Compare... ' starts the comparison operation.

4.5.1.6. File / Exit

To terminate the program, open the 'File' menu and select 'Exit'. A warning is displayed if there are changes that have not been saved. You then have the choice of saving or discarding them.

In the event of a supply failure, the events stored in the REB500 central unit remain intact for at least 24 hours.

Load events

The protection system has an event memory for every unit (central unit and bay units).

To upload the latest events to the PC, open the 'View' menu and select 'Event list'. This opens the 'Event list' dialogue (HMI500 must be in the on-line mode). Click on the 'Refresh' button to upload the events. The protection system stores the events until they are explicitly deleted.

The list viewed on the PC is refreshed either on command or cyclically. To specify the refreshing interval, select 'Tools / Settings' (see Section 4.5.6.5.).

4-33


There is no indication should the event memory overflow before the events have been uploaded. The events are updated as determined by the system response setting (see Section 4.5.3.11. 'Settings / Event memory').

The following information is shown for every event:

• Type of event P = Protection function event S = System event T = Test generator event

• Date event occurred

• Time event occurred

• Time tag valid (yes / no)

• Source of event with application, node and device ID FFFSSAAAA (e.g. BPD010004) FFF: English function designation (e.g. PDP =

Bay protection device) SS: No. of the bus section AAAA: Address of the hardware unit that

generated the event.

NOTE: The source data are important for locating hardware defects.

• Text as entered via 'Configuration/Binary module' (user defined) or alternatively, the name assigned by the system (system defined)

• Value, e.g. ON or OFF.

The width of the columns can be adjusted by dragging the border with the mouse in the table header.

Providing a printer is connected to the PC, you can print the event list by clicking on the “Print” button.

The event list can be saved in a text file on the PC with the aid of 'ASCII export'.

4.5.5. Testing

4.5.5.1. Testing / Test mode

WARNING: Switching to the test mode while the protection is in operation should only be undertaken by especially trained personnel. Incorrect manipulations can cause false tripping, for example, by inadvertently operating a tripping relay, simulating an incorrect isolator or circuit-breaker status or activating a tripping output (e.g. External TRIP). The test generator is activated by opening the 'Testing' menu, selecting 'Test mode' and entering a valid password. A tick appears next to the menu item, 'Test mode' is added to the status line at the bottom of the screen and the 'Test mode' dialogue opens.

NOTE: To enable a start to be made, the password is set to 'Test' when the program is supplied.

The test generator is used in conjunction with the 'Status of binary inputs/outputs' dialogue (has to be opened by the operator), see Section 4.5.2.4. 'View / Binary input/output status'.

When the test generator is active, the statuses of the tripping commands cannot change.

Where bay protection is installed, a test sequencer can be activated in the test mode which checks the protection functions (see Section 12.1.4.).

4-39


Fig. 4.26 Test mode

Unblock all relays

Clicking on the 'Unblock all relays' button restores the relays to normal operation and their statuses can change again.

WARNING: An output relay can now be set or reset either directly (e.g. by setting an output relay) or indirectly (e.g. via an input or by a protection function). The greatest care must be taken when using the test mode, especially when the protection system is in operation. Block all relays

Clicking on the “Block all relays” button prevents the statuses of all relays for which outputs have been configured from being changed.

Block all tripping relays

Clicking on the 'Block all tripping relays' button prevents the statuses of all tripping relays from being changed with the exception of '41810_In service', '41835_Test generator active' and '41410_Output relays blocked'.

Reset all overridden relays

Clicking on the 'Reset all overridden signals' button returns all inputs and outputs which had statuses impressed on them for test purposes to their original states.

4-40


NOTE: Blocking hierarchy • Blocking by the test generator takes precedence over all

other functions, i.e. neither a protection function nor an External TRIP signal can initiate a trip.

• Unblocking by the test generator takes precedence over all other functions, i.e. blocking by an isolator or differential current alarm or a signal applied to an opto-coupler input is cancelled.

Using the test generator

Fig. 4.27 Statuses of binary inputs and outputs in the test mode

In order to set or reset binary inputs and outputs using the test generator, it is necessary to open the 'Status of binary inputs/outputs' dialogue. Providing the test mode is active, the status of an input or output can be changed by simply double-clicking on it.

Regardless of whether they are logical '0' or logical '1', inputs and outputs are normally green, those with impressed statuses yellow and invalid ones red. Impressed statuses are green after the display is refreshed.

4-41


Shutting down the test generator

The test generator is deactivated by clicking on the menu item 'Test mode' a second time. All the relays are then restored to their original statuses, any latching is reset and blocking by the test generator is cancelled.

4.5.5.2. Testing / Installation mode

This mode is activated by opening the 'Testing' menu, selecting 'Installation mode' and entering a valid password.

A tick appears next to the menu item, 'Installation mode' is displayed on the status line at the bottom of the screen and the 'Installation mode' dialogue opens.

Click on 'Installation mode' in the 'Testing' menu to reset the installation mode. The tick in the menu item is reset.

NOTE: To enable a start to be made, the password is set to 'Install' when the program is supplied.

Restart the protection system

Clicking on the 'Restart the protection system' button reinitializes the protection.

Debug mode

In the debug mode, the protection system generates additional internal program events. As a rule, the debug mode is only used by the ABB engineering department for test purposes. In seldom cases should the corrective action suggested in Chapter 9 not prove successful, it is possible that a solution can be found using the debug mode.

Read trace ability information

The hardware data (type, serial number, revision index, date of manufacture etc.) and software data (version) are uploaded from the protection equipment and stored in the database to enable previous history to be retraced.

4-43


4.5.6. Tools

4.5.6.1. Tools / Version

This menu item is for administering the database for the specific protection system, which contains information such as settings, event texts, configuration of the binary inputs and outputs etc. Parts of the database can be edited on the PC using HMI500 and then downloaded to the protection. The database has a version number and index that are displayed in the HMI main menu.

Version: X.YY, date of the last change, description

The version is purely numerical, i.e. X {0...9} and Y {0...9}. It is assigned by ABB while processing the contract and determined at the time the system is accepted by the user. The user cannot change it subsequently.

Index: XX, date of the last change, description

The index only comprises letters, i.e. X {A...Z}. The user must change the index and its description if he changes the REB500 settings in order to document and distinguish different sets of settings. When a new index is assigned, the current date on the PC is recorded as the date of the last change.

Some of the operator program functions can be customized:

Fig. 4.33 HMI500 settings

Communication

Communication can be established with a REB500 or REB500sys system either via a serial interface or the TCP/IP protocol. The input fields for the communication parameters presented by the program depend on which of the two is chosen.

Serial interface:

In addition to defining the serial interface (COM port), there is also a setting for the Baud rate.

4-46


TCP/IP winsock:

Settings are provided for the TCP/IP address and the TCP/IP port of the REB system to which communication is being established.

It is possible to change between the communication modes On-line, Off-line and Simulation. Clicking on the 'Check Online' button causes HMI500 to check whether communication with REB500 system is active or can be established (see Section 4.3.2.1.).

Write DB download/upload log file

If these checkboxes are active, a log file is saved every time the database is downloaded to, respectively uploaded from the protection system.

Parameters for reading and exporting event data

Settings are provided for the period for cyclically reading events and the separator for an ASCII file when exporting events.

Database locations

HMI500 creates a number of configuration databases. The following dialogue provides facility for defining the directories where the databases are located and changing the database names. Default directories are created during the installation of HMI500 and it is recommended that these not be changed.

Fig. 4.34 Settings / Database locations

4-47


PSM support (option)

HMI500 automatically displays this directory when E_wineve is installed on the PC. The directory enables you to verify the response of E_wineve after disturbance recorder data have been transferred.

• Check the box 'Send notification after automatically uploading data' to obtain notification as to which disturbance recorder data have been sent. For this purpose, E_wineve has to have been started in the batch mode.

• Check the box 'Evaluate after manually uploading data from the protection system' to be offered the possibility of evaluating disturbance recorder data using E_wineve after they have been manually transferred.

• The button 'Select PSM' provides facility for locating the E_wineve installation to be used for evaluating disturbance recorder data.

Fig. 4.35 PSM support settings

4.5.6.6. Tools / Set system time

The system clock in the protection system is equipped with a standby battery and if not synchronized periodically by an external reference, runs independently with an accuracy of 150 ppm (13 s per day). The date and time are set by opening the 'Tools' menu and selecting 'Set system time'. The date and time displayed are those effective on the PC.

4-48


The settings in the fields can be incremented or decremented by clicking on the appropriate arrow to the right of the value. After making the necessary changes, click on the 'Set time' button to automatically download the new date and time to the protection system.

Fig. 4.36 Setting the system time

4.5.6.7. Tools / MMC session manager

Fig. 4.37 MMC session manager

As a rule, this function runs entirely automatically and requires no intervention by the operator. Only if after something untoward happens and an error message is displayed is it necessary to manually close sessions (e.g. if the PC is switched off without correctly shutting down the program).

Every transaction involving communication between the operator program and the protection system (e.g. reading the event list or

4-49


setting inputs and outputs using the test generator) is managed as a (DAC) session. Open the 'Tools' menu and select 'MMC session manager' to open a dialogue with a list of open sessions.

Mark the sessions to be closed and then click on the 'Close session' button. Take care when doing so that no other PC is connected to any other part of the protection system as its communication may also be terminated.

The session 'TGR_Read EMI' refers to the main communication between the operator PC and the protection system and must remain open. HMI500 has to be restarted should the 'TGR_Read EMI' session be closed by mistake.

Refer also to Section 9.2.4. 'HMI500 faults'.
