9 Introduction Introduction 1 Introduction Welcome to the RECOM Disturbance Collection program. RECOM consists of two separate programs. The first one is RECOM Disturbance Collection, for manual collection of disturbances. This program is running in a DOS environment and is integrated with SMS-BASE. The second one is Time Scheduler, which is an universal scheduling program running under MicroSoft Windows. This program is used for automatic polling of disturbance recorders and requires that the RECOM Disturbance Collection program is installed. RECOM is designed to provide a flexible tool for collection of disturbance files either directly connected to disturbance recorders, or connected via HAYES compatible telephone modems, or X.25 connections. RECOM supports collection of disturbance recordings from the REOR 100/RCRA 100 (versions 2.2 and 3.0) and the REx 5xx protection and control terminals. RECOM is designed and created by ABB Network Partner AB in Västerås, Sweden. 1.1 Disturbance recording Disturbance recording is a very effective tool for operating and design personnel to analyze the performance of the power system and related equipment during and after a major disturbance. By promptly detecting any problems and initiating the corrective actions, maximum operating reliability and availability of the power system is achieved. Disturbance recording also improves the understanding of the behavior of the power system and the associated equipment, contributing to design improvements of future installations. 1.2 Product Overview The ABB Network Partner PANORAMA Station Automation concept contains a full range of flexible and functional systems for supervision, protection and control of all parts of the power systems in electrical power networks. REOR 100 is used as a stand-alone disturbance recorder, complete with dedicated data acquisition and recording modules. RCRA 100 consists only of a recording module used when disturbance recording is a complementary function to the numerical distance protection REL 100, and the numerical 4-step earth fault protection REL 012. The REx 5xx series protection terminals can be equipped with an optional disturbance recorder function. 1MRK UEN *

10 Introduction Introduction The above mentioned disturbance recorders, together with the REVAL, RECOM, and other SMS software, are all part of the modular system within the PANORAMA Station Automation concept. The system provides object oriented monitoring with cost effective event and disturbance recording for both local and remote post-fault analysis. The disturbance recording system comprises the following products: Disturbance recording - REOR 100/RCRA 100 and REx 5xx, Disturbance collecting - RECOM (for REx 5xx and REOR 100/RCRA 100), Disturbance evaluation - REVAL Expert system for disturbance analysis - RESDA (for REOR 100/RCRA 100, and REx 5xx) Remote configuration of disturbance recorders - SM/REOR 100 (for REOR 100/ RCRA 100) and SM/REx 5xx (for REx 5xx) The interconnection between the recording units and the evaluation work stations is made by means of fibre optics and telephone modems. REVAL is integrated in SMS (Station Monitoring System) and understands the SMS directory structure. However it is possible to use REVAL separated from the SMS system, provided that the used file types can be identified by REVAL. 6 1MRK UEN *

11 Introduction Introduction 1.3 System Overview The disturbance recorder assists the design and maintenance engineers in their efforts to achieve improved power system performance. The following two figures illustrates two typical SMS configurations. Fig. 1 shows a station with local PC and a central PC connected. Fig. 2 shows a station without PC, with a central PC connected. Note that the objects monitored by the disturbance recorder units are not shown in these figures. REOR/ RCRA REOR/ RCRA SPA bus SMS-BASE RECOM REVAL RESDA Station SM/REOR 100 SM/REx 5xx SMS-BASE RECOM REVAL RESDA Central SM/REOR 100 SM/REx 5xx REx 5xx Station PC Central PC REx 5xx Fig. 1 Typical SMS system with local and remote configuration, collection and evaluation. In this station the station PC is polling the disturbance recorders for new recordings and transfers them to the hard disk of the PC for permanent storage. The central PC then collects the disturbance files from the station PC. When communicating with the disturbance recorders and protection terminals in order to change settings, the station PC will act transparently, i.e. no intermediate storage of this type of data is made on the station PC. 1MRK UEN *

27 Overview This chapter presents all possibilities offered by the functions in RECOM. The menus that form the RECOM user interface are presented with an explanation of the contents and how to operate them. 1 Overview 1.1 General The purpose of RECOM is to collect disturbance recordings from disturbance recorders and save them on hard disk for long time storage and evaluation. The RECOM software supports local and remote transfer of disturbance recordings from the REOR disturbance recorders and the REx 5xx protection terminals, to personal computers. Transfer of recordings is initiated manually, using the MRECOM program, or automatically, using the ARECOM program. RECOM consists of the following five parts: RECOM.CNF an integrated configuration module for RECOM in SMS-BASE and used by both MRECOM.EXE and ARECOM.EXE. MRECOM.EXE a manual polling program integrated in SMS-BASE (DOS). It is referred to as MRECOM. ARECOM.EXE an automatic polling program running under MS Windows and started by the scheduler utility. It is referred to as ARECOM. MODEM3.EXE a program for telephone modem handling integrated in SMS-BASE. SCHED.EXE an automatic scheduler running under MS-Windows organizing the automatic polling and the remote connections. It is referred to as Time Scheduler or the scheduler. Automatic polling is performed by ARECOM in an MS-Windows environment. ARECOM is always started by the Time Scheduler function. The operator specifies the absolute starting times or specifies time intervals between polling sequences. The polling sequence is run once for every starting time or interval elapsed, for all defined and enabled stations and objects. For more information on the Time Scheduler, refer to the Time Scheduler part of this manual. 1MRK UEN *

28 Overview SMS-BASE controls all RECOM functions through the use of RECOM.CNF. SMS-BASE changes parameters located in the files RCM-STN.VAL and RCM-OBJ.VAL. The actual collection of disturbances is handled by ARECOM or MRECOM. RECOM stores the collected recordings as disturbance files in the corresponding unit directory in the SMS structure. SMS-BASE (station or central) REOR unit REOR unit REx 5xx unit Physical Object #1 Physical Object #2 SMS Object #1 SMS Object #2 Fig. 1 SMS object level monitoring. RECOM can be a part of the following configurations: Locally connected to a single station. In this configuration RECOM polls disturbance recorders via the SPA-bus and stores the up-loaded recordings on the station PC s hard disk. Remotely connected to several stations. RECOM can handle stations with and without PCs. ARECOM works exactly as described above (except for modem handling) when polling a station without a PC. Stations with PCs are only polled for already up-loaded recordings which are stored on the hard disk of a local PC. RECOM can also address individual units in the station. See Fig MRK UEN *

29 Overview Station with PC Station without PC Object Object Object Object Object Object Station PC Central PC Fig. 2 SMS central connections to SMS stations with or without PCs. RECOM supports automatic dialling using the telephone modem function. The operator may not use manual dialling during automatic polling. 1.2 Functions The RECOM program supports: Functions in a Central PC Collection of disturbance files from the hard disk of the Station PC. This means that you can transfer files that has been previously collected by RECOM, from the Station PC to the Central PC. Polling of individual units, sorting under an SMS station without a PC, directly from the Central PC. Functions in a Station PC Polling of individual disturbance recorders sorting under a Station PC. 1MRK UEN *

30 Overview 1.3 Optional functions The following optional SMS functions are supported by the RECOM program: Deletion of disturbance files in the Central PC and in a connected Station PC through the RECOM Unit disturbance summary screen. Automatic evaluation of disturbance recording automatically collected by RECOM through the optional SMS product RESDA. Automatic printouts of the disturbance recordings automatically collected by RECOM through the optional SMS program REVAL. 1.4 Man machine communication, MMC The RECOM MMC consists of a few screens in the SMS-BASE structure. The appropriate screen is presented depending on the position in the SMS hierarchical directory structure when RECOM is started. Before RECOM is started it is necessary to have some basic knowledge of the SMS screens. In this manual, you find a rudimentary description of the Station, Object and Unit parameter settings SMS screens. For a full description of the SMS features, see Ref MRK UEN *

31 Basic operation 2 Basic operation In this chapter, a number of examples are given on how to use RECOM for disturbance collection. The main functions of RECOM are explained and exemplified. For further information of the different commands and possibilities, see Chapter 3 Extensive operation, where every used command and mouse action is explained in details. 2.1 General information To be efficient when working with the automatic polling examples in the Windows environment, you need a mouse to point at specific objects on the screen. For all alphanumeric input you need the keyboard. All the examples are based on the example structure delivered together with RECOM. It is located under the SMS\ - directory with the name RECOM_EX. RECOM_EX can be removed from the system at any time using the SMS-BASE utility Alter structure. For more information on this operation, see Ref. 1. The examples are intended as basic example of the different settings. The first action before starting any of the training sessions is to set up the system. Read Preparation on page 28 before carrying out the sessions. 1MRK UEN *

32 Basic operation 2.2 Preparation The first action is to start SMS-BASE from the DOS prompt by typing the following commands: C:\> CD C:\SMS\BASE C:\SMS\BASE\> SMSBASE It is necessary to change the application structure to the RECOM demonstration structure. The explanation below shows how this is done. For more information, see Ref Use < > to select the SETUP menu and press <CR>. Select the application structure path Appl. struct. path by highlighting it as in the figure to the right. Press <CR>. 2 Change the structure path s last directory DATA, see the figure to the right, to RECOM_EX and press <CR>. 3 Save the new settings by positioning to the Save set-up line and press <CR>. 4 Press <ESC> to leave the SETUP menu. Use < > to select the SELECT menu. You are now ready to start using RECOM. 28 1MRK UEN *

33 Basic operation 2.3 RECOM handling Checking disturbances stored in a PC Follow the example below to examine the stored disturbance recordings on your Central PC, for a disturbance recorder located in a station with a Station PC. 1 Select the station in the SMS-BASE structure. The MODEM and the RCM- MODEM keys are now presented on the bottom of the screen as the <F3> and <F4> keys. 2 Normally, press <F3> to start the modem handler, or <F4> to start the X.25 modem handler. Press <D> to dial the number. When communication is established, press <Esc> to exit the modem handler. In this case, when no real disturbance recorder and station are available, just skip this step regarding the modem handler. 3 Select station Alpha and press <CR>. Fig. 3 Select the station Alpha in the SMS-BASE structure. 1MRK UEN *

34 Basic operation 4 Position to the disturbance recorder and start RECOM by pressing <CR>. Fig. 4 Select the RECOM Unit disturbance summary. 30 1MRK UEN *

35 Basic operation 5 The RECOM start-up screen is now presented, see Fig. 5. During communication to the disturbance recorders, or Station PC, information text on the actions taken by RECOM is presented on the screen while the program is colecting data. When the information collection is ready, the RECOM Unit disturbance summary screen is presented, see Fig. 5. Fig. 5 The RECOM Unit disturbance summary 6 The functions and possibilities of the RECOM Unit disturbance summary screen are explained in RECOM Unit disturbance summary on page 48. Since no connection is made to the Station PC, only the Central column contains information showing which disturbances that are stored on the hard disk of your PC. In the upper right corner of the screen, the text PC in station indicates that a PC is installed in this station. However, since no connection is made, the text ON -LINE is not shown. By default, the first disturbance is automatically highlighted when the screen is first presented. If communication is established, place the highlight bar on the disturbance to be up-loaded and use one of the up-load functions to transfer the data. Up-loading of a REVAL header file, for example, is ordered by pressing <H>. A data transfer in progress message is presented during the file transfer operation Identifying new recordings There are two ways to identify new recordings: The first way is to make a remote connection from the Central PC and compare the Central and Station columns. If there are more recordings stored in the Station than in the Central column for a unit, this indicates that new recordings are stored and can be up-loaded. The second way is to connect the Central PC to a station without a PC and observe the stars in the New column indicating that the recording is new and not yet transferred. 1MRK UEN *

36 Basic operation Printing a list of stored recordings A list of stored recordings from the Station disturbance summary screen and the Unit disturbance summary screen can be printed on a connected printer, see Fig. 13 and Fig. 15. To start the printout, use <P> Starting a Poll sequence In some cases, it can be necessary to order a remote Station PC to immediately start a new automatic poll sequence. This is possible through the REPOLL order. Follow the instructions below: 1 Position to the station of interest with an installed Station PC. 2 Establish communication with the modem handler by pressing <F3> or <F4>. 3 Start RECOM Station/Station disturbance summary. 4 The Station disturbance summary screen is presented as shown in Fig Note the time of the previous polling occasion, i.e. Latest auto poll. 6 Order a repoll of all the disturbance recorders in the station by using the REPOLL command, i.e. press <O>. All the disturbance recorders in the station are now being polled and the new disturbances are up-loaded to the hard disk of the Station PC. 7 While the disturbance recording(s) is transferred, a transfer message is shown in the message line. You can choose to remain in the picture and wait for the polling to be completed, or do something else in the meantime. 32 1MRK UEN *

37 Basic operation Manual starting of automatic polling The automatic poll sequence can be manually started from Windows. This means that all stations connected to the Central PC are polled for new disturbances. The ARECOM icon in the SMS group, if created during installation of RECOM, is used for this purpose. If the ARECOM icon was not created during the installation, follow the steps below to perform this: 1 Activate the Windows desktop and click on the right mouse button. 2 Select New/Shortcut. 3 Click on Browse. 4 Go to the directory C:\SMS\RECOM. 5 Select the file ARECOM.EXE and click on Open.

Short command is <E>. Exit from RECOM to SMS-BASE. Short command is <X> or <Esc>. Use <Page Up>, <Page Down>, < > and < > to navigate among the disturbance recordings on the screen Self Supervision Since ARECOM performs automatic polling, it handles erroneous situations automatically. The basic error handling function is to log errors in a log file, and then continue with the next station/object/unit. When ARECOM fails to connect to a station or an object, the exception is logged in the log file. Also during manual operation of RECOM, i.e. using RECOM in SMS-BASE, all actions, both normal and abnormal are continuously logged in the log file. The log file must not become too large. If so, it is very difficult to analyze. To prevent this, RECOM starts a new empty log file, RCM-LOG.nnn where nnn is an incremental three digit sequence number, when the current log file reaches a certain size. The maximum size and the maximum number of log files are controlled through the initialization file. For more information, refer to Chapter 4 Appendix. The new log file is given the same name, but with an incremented sequence number. The old log file remains on the hard disk until the operator deletes it, or RECOM overwrites it. 1MRK UEN *

56 Extensive operation It is possible to list the log files stored on the disk. In DOS systems, use the DIR command: C:\> DIR C:\SMS\RECOM\DATA\RCM-LOG.* Volume in drive C is DOS500 Volume Serial Number is AD6 Directory of C:\SMS\RECOM\DATA. <DIR> :18p.. <DIR> :18p RCM-LOG :04a RCM-LOG :28a RCM-LOG :51a RCM-LOG :51a RCM-LOG :05p RCM-LOG :56a 8 file(s) bytes bytes free In this example, there are six log files present. The most recent has the sequence number 007. In Windows 95/Windows NT systems, use the standard Windows Explorer application. There is no built-in function to view the log file in RECOM. However, you can use the Windows functions Write, Word or Notepad to view the files as described in Section Checking log file Restart The system may be interrupted when the system is in automatic poll mode, or during an automatic polling sequence, due to a power failure, or some other reason. This causes the polling sequence to stop. To minimize the need for maintenance, due to this type of errors, the system has a recovery function that restarts the RECOM function at power up. As soon as the Time Scheduler is started, it goes through the process activation list, and ARECOM continues to poll the station(s), according to the schedule, when the system comes back into operation. The SMS system ensures correct initialization of the system (station or central) after a power failure Installing RECOM in the SMS-BASE structure After a successful installation on the hard disk of the PC, RECOM is ready to be used in the Application structure of SMS-BASE. For each station and object in the structure that contains a disturbance recorder, it is necessary to enter RECOM Station and RECOM Object modules. These modules contains parameters necessary for RECOM to function properly and must therefore always be installed in the correct places in the structure. 52 1MRK UEN *

Time Scheduler is executing on a Windows system using a mouse for easy and efficient operation. Time Scheduler, or Scheduler for short, offers two major functions: Starts application programs on specified times. This is used for automatic polling of disturbance recorders by making Scheduler start the RECOM program for automatic polling, i.e. ARECOM. Makes the central/station connection possible. This means that a Central PC can connect to the Station PC. Then the disturbance files stored on the Station PC can be transferred to the Central PC. The Central PC can also communicate directly to the disturbance recorders and protection terminals in the station via the Station PC. For this purpose, Scheduler makes the Station PC transparent for the SPA messages coming in on one COM port, simply by passing them on to the second COM port. This function is always active when Scheduler is started. Scheduler enables entering a window, selecting programs and adding them to a program queue for execution. The start time and periodicity for each program execution can be specified. Scheduler handles the program queue and automatically starts execution of programs according to the specified time and periodicity. Scheduler is co-ordinated with SMS. The installation procedure allows the user to specify if the Scheduler is to be installed on a Central PC or a Station PC. In a station, connection to the remote process and SPA bus is established via communication ports. In the station, the Scheduler program object can be added to the Auto start program group. In the central, the Scheduler program object is installed in the SMS program group. See also Chapter 1 Installation Scheduler overview This section explains how Scheduler is intended to be used in different system configurations. 56 1MRK UEN *

61 Extensive operation Scheduler functions in the system context A Station PC with a Central PC connected In the Central PC, Scheduler is used for starting applications, for example, the ARECOM auto poll program. On the Station PC, the Scheduler receives and handles the messages sent from the Central PC via the modem. This makes the Central-to-Station connection possible. If the incoming message to the Station PC is a SPA message, the Scheduler sends it directly to the SPA bus communication port, and the answers received are passed directly to the modem port and the Central PC. A stand-alone Station PC The Scheduler is used for starting applications, such as the ARECOM auto poll program. A station without a PC, with a Central PC connected In the Central PC, Scheduler is used for starting applications such as the ARECOM auto poll program Scheduling Algorithm Scheduler does not allow several programs to execute simultaneously, i.e. one program is not allowed to start if another program started by Scheduler is still executing. Scheduler waits for program termination before the next program can start.! Note! If, for example, the clock.exe program is started, Scheduler does not allow any other application to start since the clock application never terminates. Thus, this kind of application should not be started by Scheduler! Execution of a scheduled program is interrupted if a remote process requests execution of an application. The scheduled program is then terminated. If a SPA command is received from a remote process, i.e. the Central PC, a scheduled SPA application is terminated. This is done to implement the SPA port as a non shareable resource Program parameters The program parameters used by Scheduler are described below. The program parameters on the command line can be added or removed by the user from the Information.. window in the Program manager. Station If Scheduler is installed in an SMS station, this parameter should be specified. Scheduler establish connections to the modem and SPA ports. 1MRK UEN *

62 Extensive operation Minimized If Scheduler is to be executed minimized, i.e. iconized, this parameter must be specified. The start window is then not presented at start-up. This is the default setting after installation. LOG If this parameter is specified, Scheduler produces a log file on the data directory. The log file consists of errors and warnings occurred during execution. IDMlanguage <language number> This parameter specifies the language to be used. The languages implemented for program version 1.4 are: English (default) Swedish Italian The text string on the Command line in the Information.. selection in the Windows Program Manager may look as follows: C:\SMS\SCHED\sched.exe station minimized log -IDMlanguage The Scheduler program handling Fig. 21 Starting up the Scheduler program 58 1MRK UEN *

63 Extensive operation When Scheduler is started, the start-up window appears and presents the name of the program and the ABB logotype. After a delay of two seconds the copyright declaration and licence information are added as shown in Fig. 21. The presentation of the start-up window can be interrupted by pressing Enter, otherwise the window remains for 10 seconds before the Scheduler window is presented. If Scheduler is started in minimized mode, which is the case when the SCHEDULER icon is used for start-up, the start-up window described above never appears, i.e. Scheduler runs iconized Handling Scheduler is executing on a Windows system which means that the user interface is operated with a mouse to facilitate flexible and effective communication Menus Terms and actions Click: Press the left mouse button once. Double-click: Press the left mouse button twice in rapid succession. Select an object:point at the object and click. The windows that build up the user interface of Scheduler are presented on the following pages along with an explanation on how to operate them. Examples are given in Chapter 2 Basic operation.

64 Extensive operation Fig. 22 The Scheduler window Data to be entered Scheduled Program Including path and optional parameters Working Directory START TIME PERIODICITY FUNCTION The list box in the centre of the window presents all the scheduled programs. Programs can be added or removed from this list. Note that the same program can be entered in the list several times with different start times and program parameters. Up to fifty (50) programs can be added to the list box. Infinite application programs (programs that never terminates) should not be included in the list, if several applications is expected to be executed. If an infinite application is started from Scheduler, any other application will never be allowed to start, once the infinite application has been started. 60 1MRK UEN *

65 Extensive operation The start time of the program is specified in the START TIME group box. If the program is to be executed periodically, this is specified in the PERIODICITY group box. In the FUNCTION group box it is possible to enable or disable a program for execution in the Enabled check box. It is also possible to set a check box to define the program as a so-called SPA application. It is important to set the SPA Application check box for all applications that communicate with the SPA bus. The Scheduled Program edit text field above the list box can be entered and program parameters can be added to the program. The Working Directory edit text field defines the directory to be used when the program is executing. The default working directory is the directory where the executable file is stored. In the following example, the automatic polling function in RECOM, i.e. the ARECOM program, is selected and the start time is set to 18 oo (6 PM) and the periodicity to 12 hours. This means that the program is executed twice a day, 18 oo and 06 oo (6 AM). Follow the actions listed below to enter this information in the Scheduler: 1 If scheduling is activated, press Stop to deactivate scheduling. 2 Click on Add... The Add... window is shown. 3 Set the directory path to..\sms\recom. 4 The ARECOM.EXE file is now presented in the File list box to the left. Select this file and then click OK. 5 Place the cursor in the Working Directory edit text field and enter the path to the first station in the application structure, e.g. C:\SMS\DATA\o001\s001, where o001 stands for organization 1 and s001 for station 1 in the SMS-BASE application structure. Press <Enter> to verify the directory. 6 Set the start time in the START TIME group box. 7 Set the periodicity in the PERIODICITY group box. 8 The Enabled check box must be checked for the program to be executed. The SPA application check box must be set for the ARECOM program. 9 To activate scheduling, click on Start. The functions of the buttons defined in the Scheduler window are described below. Buttons Start/Stop activates/deactivates scheduling. Note that the function handling the communication from the Central PC is not stopped with this button. This is only stopped when exiting Scheduler. Delete removes the selected program from the Scheduled Programs list. Add... enters the Add... window to select a program and then add it to the Scheduled Programs list. 1MRK UEN *

66 Extensive operation Menu items Help/Index, Help/Menu Commands, Help/Using Help and Help/About Scheduler presents help and information texts. File/Exit terminates Scheduler. View/Configuration presents the Configuration window. In this window the telephone modem port and the SPA communication port settings on a Station PC are presented and modified. On an Central PC the View menu is disabled! Configuration window The Configuration window presents the communication settings and other associated port information in a Station PC. The presented values can be modified. Fig. 23 Scheduler Configuration window. In the following example, a modem is connected to port 1 and the SPA bus to port 2. The communication settings for the modem port is: Baud rate, Parity, None. Number of bits, 8. Number of stop bits, MRK UEN *

67 Extensive operation The communication settings for the SPA port are changed by SMS-BASE and not available for modification from Scheduler. The timeout for a SPA session is defined in seconds. A SPA session is started every time the client process sends a SPA command to Scheduler. When a SPA session is started, scheduled SPA applications are prohibited to start. A SPA session is terminated when the timeout is reached. If you have modified any of the values in the window, press OK to verify the new settings. It is important that the port configuration is correct on the Station PC. For normal use, both Port active check boxes should be selected. Only for special applications, when having the Station PC communicating with both the Central PC and the SPA bus via one and the same COM port, and telephone modem, the SPA port Port active should not be selected. 3.3 The modem program This section presents all the possibilities that MODEM3 offers and available functions included General MODEM3 incorporates the following features: Establish communication through telephone modems. Establish communication over packet switched networks (X25). Combinations of the two Adapting the program to your environment Modems and X25 networks behaves in different ways depending on make and configuration. They need different terminology for establishing a connection. Also the criteria for success or failure are different. The information about this behavior is stored in a file with the name MDM-PHN.DAT in the..\sms\base\support directory. It is referred to as the data file in the rest of this chapter. The data file contains the fingerprint of the communication device (modem or PAD), holding the result codes for successful and unsuccessful operations, as well as the codes for initialization and connect/disconnect. The default data file is located in the support directory. If different modems are used in the organization, for different stations, the data file can also be copied to a station catalogue. When the function is running it will first look for a local version of the data file on the station directory. If this is not found, it uses the default data file on the support catalogue instead. 1MRK UEN *

68 Extensive operation The delivered default data file, on the support directory, is supporting standard HAYES compatible telephone modems. If the installed modem is not a standard HAYES modem, and/or does not function properly when connection attempts are made, the data file needs to be modified. To change modem type, use the Modem Types shortcut icon to start the modem type selection program, see Fig. 24. Select your modem type from the list box, and then press OK. Fig. 24 The Modem Types selection dialogue box. If your modem is not listed, read Section Customizing MODEM, or else go to Section 3.4 Handling MODEM Customizing MODEM This section describes how to modify the MDM-PHN.DAT file to adapt to a new modem type. During this work you will need the reference manual for your modem. It is referred to as the modem manual in this section. There are a few rules to be kept in mind while editing the data file. They are listed below and also in the header of the data file. 64 1MRK UEN *

69 Extensive operation The following rules must be followed when the data file is changed: There must be a copy of the data file in the SUPPORT directory. Comments are started with a exclamation mark!. Comments may be added after a command but must start with a! Note that the qualifiers, preceding the = signs must be written in English for translation. Only the first 80 characters per line are significant. The delimiter sign can be changed to any character that is not part of the modem syntax. The delimiter sign is defined after the DELIMITER qualifier. When a delimiter is given in a string it will cause RECOM to send a CR character to the modem. If a number n is given between two delimiters, it will cause RECOM to wait for n seconds. If two delimiters are given in sequence, this causes a status check. Control characters are written with a preceding ^ character, i.e. CR = ^M. RTS is turned on by adding a + for on and - for off, i.e. ;RTS+; will turn the RTS signal on. %no% will be replaced with the telephone number Enter the DOS editor by typing EDIT at the C:\-prompt. If you are not familiar with the DOS edit utility, please refer to your DOS manual. Position to the..\sms\base\support directory or the station directory, if a local data file is used. Open the MDM-PHN.DAT file. It is recommended to copy a version of the file to MDM-PHN.OLD before you start changing the file. Define a delimiter. The delimiter can be any character that is not part of the telephone number and not part of the communication device command language. ABB Network Partner suggest that you use a semi-colon, ; if not in conflict with your equipment. In the rest of this description it is assumed that a semi-colon is used. 1MRK UEN *

70 Extensive operation Position to the DELIMITER= -field. 1 Replace the existing delimiter with a delimiter of your choice. A typical string looks like DELIMITER=;! Delimiter used in the command strings 2 Enter the initialization string. The initialization string is sent to the modem before the number is dialled. It is wise to start the initialization string with a Hang-up command. This way you ensure that you are disconnected before a new dialling is performed. If the initialization string is terminated with a command that generates a return code, successful or not, a operation success check is added as a double semi-colon. 3 Find the section showing the control codes in your modem manual. Position to the INIT= -field in the data file and replace the existing codes with the following codes from your modem manual. The normal HAYES codes are shown within parentheses. 4 Reset the modem (ATZ) 5 Do not echo characters from the keyboard to the screen in command state (ATE0) 6 Return result codes, normally factory setting is on, (ATQ0) 7 Display return codes as numbers, (ATV0) 8 To check the success of the operation, add a double semi-colon at the end of the string. These are the codes normally necessary. If the modem connects and then disconnect directly add the following: 1 Ignore status of DTR signal (AT&D0) A typical string looks like: INIT=ATZ E0 Q0 V0;;! Initialisation string to be used 2 Define the codes meaning Successful execution of command. 3 Find the section in the manual that states the return codes. Position to the CONNECT= -field. 4 Replace the existing codes with the codes corresponding with your modem. Place a delimiter between each code. A typical string may look as below: CONNECT=0;1;5;10;11;12;13;14;15;16;17;18;19;20;21! Codes for connect OK 66 1MRK UEN *

71 Extensive operation 5 Define the codes meaning Command failed. 6 Find the section in the manual that states the return codes. Position to the NO_CONNECT= -field. 7 Replace the existing codes with the codes corresponding with your modem. Place a delimiter between each code. A typical string may look as below: NO_CONNECT=3;4;6;7;8! These codes means connection failed 8 Define a time out, i.e. if no return code is returned (good or bad) the modem will wait for this number of seconds before deciding that the operation has failed. 9 Position to the TIME_OUT= -field. 10 Replace the existing time-out with the time corresponding with your modem. A typical string may look as below: TIME_OUT=30! seconds. 11 Define the dial-up code. The dial-up code consists of two parts, the command and the number part. The number part is defined in SMS-BASE when you define the station along with the port parameters. See Ref. 1 for more information on SMS-BASE configuration. 12 Find the section in the modem manual holding the dialling command(s). Position to the DIAL= -field. 13 Replace the existing codes for dial-up corresponding with your modem. (ATDT). 14 To insert the telephone number, taken from SMS-BASE by the function, add a %no%. 15 If your telephone number is divided into two or more parts, with a result code between, take action 15 and 16 else skip to Add a double delimiter ;;. This will force a check of the result code before the dialling continues. 17 Repeat action 13 and 14, and if necessary, also 15 and 16.! Note! The number specified in SMS-BASE must be separated by a delimiter into two or more parts. 1MRK UEN *

72 Extensive operation 18 Add a double delimiter to check the operation result. 19 If any codes are needed after the connection is established, add them in the order they are to be sent. A typical string may look as below: DIAL=ATDT%no%;;! ATDT Tone dialling 20 Define the hang-up command. The hang-up command will terminate your connection. 21 Find the section in the modem manual that states the hang up sequence. Position to the HANGUP= -field. 22 Replace the hang-up codes with the codes corresponding to your modem. 23 After the + characters, normally you must wait a second or two. Check what applies to your modem and add the number of seconds to wait between two delimiters. The modem is now in command mode. 24 Add the command for hang-up. (ATH) 25 Add a double delimiter to check the operation result. A typical string may look as below: HANGUP=+++;2;ATH;;! +++, wait two seconds, ATH The hang-up command is now finished. As mentioned earlier, it is also wise to add it in the init string, before initialization. A typical string with initial hang-up may look as below:: INIT=+++;2;ATH;;1;ATZ E0 Q0 V0;;! Initialisation string to be used 26 Define a wait time in ms to be used between the characters sent to the modem. 27 Position to the DELAY_TIME= -field. 28 Replace the existing delay time with the time corresponding to your modem. A typical string looks like: DELAY_TIME=100! Number of ms between characters X25 operation In principal, there are no major differences between dialling over a modem or a packet switched network. However, there are a few extra parameters necessary for the X25 operation. The MODEM3 program is able to control the RTS. This is achieved through the use of the RTS+ and RTS- strings. The RTS+ string turns RTS on and the RTS- string turns RTS off. The strings can be entered anywhere in the INIT, DIAL or hang-up syntax. 68 1MRK UEN *

73 Extensive operation There is also a need to send control characters. This is achieved by adding a hat (^) in front of a control character, for example, ^M results in sending a <CR> sign and ^P sends <DLE>. The control characters can, like the RTS control, be included in any string. 3.4 Handling MODEM Man machine communication, MMC The MODEM3 program is invoked using <F3>, or a menu selection in SMS-BASE. All modem actions are initiated by the use of quick selection keys. The selection keys and program messages are language dependent and presented on screen line 25 when the program is running. Language selection is managed through SMS-BASE. The only MMC available when the program is running is the information on screen line 25. When the MODEM3 program is started on order from another program, the MODEM3 program enters silent mode and no messages are presented. Every message is shown for 3 seconds, or more to ensure that the operator has time enough to read it Opening a connection, Dialling The dialling is initiated through the quick selection key D. The program presents messages of on-going activities and operation result Closing a connection, Hang-up The hang-up is initiated through the quick selection key H. The program presents messages of on-going activities and operation result X25-operation There is no difference from the modem handling for the calling an hanging-up operation for the operator. 1MRK UEN *

76 Appendix Terms Automatic Polling SMS 010 SMS-BASE SM/REOR 100 SM/REx 5xx SPA-bus Station Station PC Unit Up-load Explanation This is a method for automatic disturbance collection from the connected disturbance recorders. Automatic polling can be performed with certain pre-set intervals. PC based Substation Monitoring System running under DOS and Windows. SMS 010 is also part of the Substation Automation concept PYRAMID within ABB Network Partner. The software platform for all SMS (Station Monitoring System) applications. A PC-based platform for the software modules for monitoring of the protection units and handling of disturbance recordings. The software package, running under SMS-BASE, used when reading and setting various parameters in the REOR unit. The software package, running under SMS-BASE, used for setting, configuration and monitoring of the REx 5xx protection and control terminals. The galvanic or fibre-optical network used to interconnect protective relays, disturbance recorders and personal computers (PC) into an SMS station. The SPA-protocol is described in appendix A. A station where one or several disturbance recorders that communicates with RECOM are installed. In RECOM the station name is used for identification by the operator and to create a directory for objects. A personal computer (PC) with the SMS software. A Station PC supports remote communication to a Central PC. A REOR or REx 5xx disturbance recorder unit that monitors (part of) an object. Throughout this document the word unit refers to the disturbance recorder unit. Transferring of information from a disturbance recorder to a PC running SMS-BASE and RECOM, or from a Station PC to a Central PC. 4.2 The SPA protocol The SPA concept defines a master-slave system for the communication between one master unit and a maximum of 899 slave units connected to nodes along a loop-shaped bus. The physical link as well as the communication protocol are defined. Normal use of RECOM does not require any knowledge of the SPA concept. Still, a short presentation is included so that the user gets a better view of what is happening behind "the curtain" during the communication activities. A full description of the SPA concept is given in other documents available from ABB Network Partner. 72 1MRK UEN *

77 Appendix The physical link comprises an optical fibre connecting all the slaves in a network in a loop or in a star network. Each slave unit is connected to the loop with a transparent optical/electrical/optical transceiver. Hence, all the messages pass by each slave unit, which only listen to the messages at this stage. The master unit always initiates the dialogue with the slave units and it addresses one slave unit at a time. Only the addressed unit responds Protocol The protocol is based on ASCII characters, but only the first 128 characters of the ASCII table are used. Hence, the characters are coded in 7 bits. A parity bit (EVEN) gives 8 bits in total. For serial communication, RS-232 with one stop bit is utilized. This RS-232 format is used on the optical fibre loop too. The loop-shape of the SPA bus indicates that a message from the master returns to the master immediately. After a certain delay time the reply arrives from the slave unit. A simple message from the master unit is formed in the following way: > Master signature as a start character Slave number The number of the addressed slave Message type E.g. R = read, W = write Channel number Channel = Part of the protection Data category E.g. I = input, O = Output, F = identification Data number Consecutive number : Delimiter Data Data : Delimiter Checksum 2 characters Carriage return Stop character Line feed Stop character A reply from a slave unit is formed in the following way: < Slave signature as a start character Slave number The number of the sending slave Message type E.g. A = acknowledged, D = data : Delimiter Data Data : Delimiter Checksum 2 characters Carriage return Stop character Line feed Stop character Where: The checksum may be replaced by XX if it is not calculated. A message without data contents takes only one ":". 1MRK UEN *

78 Appendix As an example of a dialogue the initial identification of a slave unit is shown below. The slave unit is assumed to have slave number 23: Master >23R0F0:XX No data, checksum unknown. SPA id=0f0 should give the protection type as reply. Slave <23D:REOR 100:6A The answer is: "This is a REOR 100 unit". This dialogue can be used to check the communication with the terminal emulator. Each quantity read or set over the SPA bus requires a dialogue. The master unit RECOM asks or commands, and the slave unit REOR 100 responds. Each transferred quantity involves the exchange of approximately 25 ASCII characters. 4.3 Using RECOM and no SM/ module It is possible to use RECOM also when SM/REOR 100 and/or SM/REx 5xx is not installed on the PC used for SMS. The selections in the structure then differs somewhat as explained in the following sections Installation Follow the normal installation procedure, i.e. RECOM is installed but in this case not SM/REOR 100 and/or SM/REx 5xx Adding a disturbance recorder in the application structure The selections RECOM REORV2, RECOM REORV3 and RECOM REx5xxV1 are available in the Alter application structure utility in SMS-BASE, in the list presented when adding modules by pressing <A>, see Fig. 25.
