1. Introduction 1.1. PowCom for Windows is a program for communication and control of Powec

power supply and supervision systems. A function for viewing the battery test data is available in the program. Discharge curves can be displayed and the program even contains a database function for saving the battery tests. PowCom can communicate with a large number of rectifier systems. The amount of functions available may vary. This means that some of the functions described may not be available on a particular system Context sensitive help is available at any time. By pressing F1 the help system will open the help page for the active window or menu item.

2. Hardware requirements

2.1. The program require a PC with Microsoft Windows v3.1 or higher. One serial port has to be available. Modem/null-modem cable must be connected to a serial port.

2.2. The modem must be Hayes compatible and communicate on one of the

following baud rates: 2400, 4800 or 9600. The baud rate must be at least as high as the one in the PPS system.

2.3. PowCom will automatically adjust itself to the baud rate in the PPS system if it

is lower than the one in PowCom. Therefore, it is possible to call a system which has a modem with the baud rate of 2400, with a 9600 baud modem. However, the PPS system cannot be adjusted to a lower baud rate. Therefore, it is impossible to call a system which has a modem with a baud rate of 9600 and which is adjusted to 9600 baud, with a 2400 baud modem.

3. Installation

1. Make sure no other programs are running. In particular do not run the Microsoft Office Icon bar while installing.

2. From Windows run Setup.exe from Disk 1 3. If you get any warnings click the Ignore button

In most cases warnings are caused by DLL’s in the WINDOWS/SYSTEM directory being newer than the version on the install disk. This is normally not a problem.



4. Installation of modem in PPS 15.00/PPS 30.00 system 4.1. Connect the modem to 9-pins serial port on PCU 30.00, (PL2). A cable for PC

with 9-pins serial port can be used. 4.2. Enter the PCU 30.00 menu system; MENU-CONFIG-LIMITS-TEST DATA-

OTHER-MODEM. Select baud rate 2400, 4800 or 9600 depending on the modem.

4.3. Connect modem and turn it on. Press MODEM INI. (NOTE! Never press

MODEM INI while modem is on line and communication is ongoing.) The modem switches to "Auto-answer modem" and is ready for receiving data.

4.4. Call up the system. If the operation fails, repeat the installation.

5. Installation of modem in PPS 6.00 system 5.1. Connect modem to 9-pins serial-port on PPR 6.C00D/E, (PL232). A cable for

PC with 9-pins serial-port can be used. 5.2. PCU 6.00D/E always communicate with 2400 baud rate. 5.3. When PCU 6.00D/E is activated, a communication line is transmitted to the

modem. Pull out and in the PCU 6.00D/E (to initiate the modem). The modem switches to "Auto-answer modem" and is ready for receiving data.

5.4. If the operation fails, repeat the procedure. 5.5. Parameters is stored in the modem, but may be changed if the modem is

connected to other equipment. 5.6. Initiation is not necessary if the modem is shortly disconnected, or power

supply disappears.

6. Installation of modem in PPS 3.00/5.00/10.00/PCS system 6.1. Connect modem to 9-pins serial-port on the front of the control module. A

cable for PC with 9-pins serial-port can be used. The control module always communicate with 2400 baud rate.

6.2. Connect modem and turn it on. Enter the menu ‘MISCELLANEOUS’ and press

‘INITMODEM’.



6.3. The modem switches to ‘Auto-answer modem’ and is ready for receiving data. 6.4. If the operate fails, repeat the procedure. 6.5. Parameters are stored in the modem, but may be changed if the modem is

connected to other equipment. 6.6. Initiation is not necessary if the modem is shortly disconnected, or power

supply disappears.

7. Null-modem cable 7.1. If a null-modem cable is used to communicate directly to a control unit without

using modem, select Communication/ Direct communication. The baud rate for both PowCom and the control unit should be the same. If the baud rate for PowCom and the control unit is different, it is impossible to get contact.

7.2. The cable shall be connected to 9-pins plugs as following:

235

235



8. Main window

Example. Main window for PCU 30.00. When PowCom is connected to a system the main window will display various information about the system, like voltage, current, etc. The information may vary depending on the particular system, so not all the information listed here will be available on all systems.

8.1. System voltage

Displays the voltage of the system. 8.2. System voltage 2

Is usually the same as system voltage. However, if the system contains a DC-DC converter, two different voltages can be measured.

8.3. Load current Displays the current to the load.

8.4. Battery current

Displays the current to the battery (if the current is negative the battery is discharged).

8.5. Rectifier current

Displays the current to the rectifier.



8.6. Distribution current Displays the current in the different distribution modules

8.7. Fuse alarm

Indicated with green if everything is OK. Alarms will be indicated with red. 8.8. Modules

Grey square indicate module not installed. Green square indicate module OK. Red square indicate module alarm.

8.9. Alarm relay

Displays the alarm condition. The indication squares are red in case of alarm, otherwise green. By clicking with the mouse on one of the indication squares, a window with the alarm texts will be displayed. On some systems a yellow square will be displayed, if there are any messages on the systems that do not lead to alarms. The information texts will be displayed in the alarm text window together with the alarms.

8.10. Temperature

Displays the temperature if temperature measurement is installed in the system. Otherwise it will print: No measurement.

8.11. Show symmetry voltage

A window with measurement of symmetry voltages will be toggled by this button.

8.12. Symmetry voltage

Displays a list of measurements of symmetry voltages. If the battery/batteries contain 18 cells, one of the measurements for each battery will be 0.00V.

8.13. Status indication

A text field indicating the charging status of the system. (NORMAL, BOOST, TEST, SPARE, etc.



9. Telephone list

In the telephone list name, telephone number and baud rate may be entered (without limitation of length on name and telephone number). Several telephone lists can be used, and these lists may be protected with a password. It is also possible to use call-back. If no baud rate is entered, 9600 will be used. If the modem you want to communicate with, is adjusted to a lower speed, the program will automatically adjust the speed when contact is achieved. To call a number, select the actual line in the list and press CALL. If the list does not contain the number you want to call, press OTHER NUMBER and enter the telephone number, baud rate and call-back if wanted, and press OK.

9.1. Calling

This window is displayed when the modem is used. Messages from the modem will be shown in the text area If the modem does not get in contact with the system and gives messages like NO CARRIER, BUSY or NO DIAL TONE PowCom will not hang up. The user will have to press CANCEL CALL to hang up. When connection is made the stored installation information on the system is shown and the system password have to be entered.

9.2. Password

When connecting to a system you will have to enter the password for the system. The password is 1234.Some systems will also require password to accept parameter updates.

9.3. Edit telephone list

To edit the telephone list, select a line and press CHANGE. There will always be one free line at the bottom of the list, enabling the user to add new numbers by using this line. To delete a line in the telephone list, select a line and press DELETE. To change telephone list, press NEW PHONE LIST and select a file. If a file name which does not exist is entered, a new list will be created. To change the password for the active telephone list, press NEW PASSWORD. Enter your old password. Then, enter the new password twice to ensure correct spelling. The password can contain all kinds of letters and numbers, and the system will distinguish between small and capital letters.



9.3.1. Modem initialisation To change the init. string for the modem, press MODEM SET-UP and enter the string. Some hints: Switch data compression off, select direct asynchronous communication, set the terminal speed to follow the line speed, select no hand shake. For some modems this is adjusted from the factory. However, for high speed modems the user usually has to switch data compression off (v42/MNP) Examples of suitable init. strings for some modems: US Robotics Sportster 14400 AT&K0 Lasat Unique 14400 AT&Q0&K0 UCOM Fastlink 14400 AT&Q0 HIDEM 14400 fax AT%C0\N1 HANDY 144 CC AT&F&C1&Q0&K0 XLINK 28800 AT%C0\N1 (Rockwell chip set)

10. Telnet communication The Telnet option will enable PowCom to communicate through a Telnet session over a TCP/IP network. PowCom needs an IP address and a port number to a Telnet device that can direct raw data to a serial RS232 port. Note: The telnet device has to support a raw 8-bit data through port without telnet character processing. Often a special TCP/IP port number is used for this type of connection. The Omnitronix SNMP Link SL60 is an example of such a device that supports raw data through a serial port when using TCP/IP port number 2000. The serial cable between the control module and the telnet device should be a null-modem cable.

10.1. Telnet

The address list for system names, IP addresses, Port numbers and initialisation strings will appear when Telnet communication from the pull down menu is chosen.

10.2. Password Protection

To change the password for the active telnet list, press NEW PASSWORD. Enter your old password. Then, enter the new password twice to ensure correct



spelling. The password can contain all kind of letters and numbers, and the system will distinguish between small and capital letters.

10.3. Edit the Telnet List

To edit the telnet list, select a line and press CHANGE. There will always be one free line at the bottom of the list, enabling the user to add new numbers by using this line. To delete a line in the telnet list, select a line and press DELETE. To change telnet list, press NEW TELNET LIST and select a file. If a file name which does not exist is entered, a new list will be created.

10.4. Telnet Init String

The telnet init string is a string that is sent to the telnet device when the connection is made. This string has to contain the correct commands to set the telnet device up to port all data to an RS232 serial port. The commands available are: {text} Makes the init sequence wait until "text" is received from the telnet

device \e Inserts an escape character (Chr(27))

\r Inserts a carriage return character (Chr(13))

\l Inserts a line feed character (Chr(10))

, Sends the string preceding the comma

\f Turns off doubling of Char(255)

10.5. Init String Example

The init string for SNMP Link SL60 should look something like this: \e\e\e{Exit}1{password}ACCESS1\r\l



This string will initialise communication with the SNMP Link I/O port 1. The Baud rate of both the PCU/PCS and the SNMP Link box has to be identical, i.e. 9600 baud (8,N,1).

11. Direct communication Is used when the system is connected directly to the PC through a null-modem cable. It is very important that comport and baud-rate is correctly set before selecting "Direct communication". When connection is made the stored installation information on the system is shown and the system password have to be entered.

12. Network connection The purpose of this window is to establish a connection to a TCP/IP server that act as a link to a network of rectifier systems connected to that server. To be able to use this a server program must be running on this computer or on another computer reachable in the TCP/IP network. TCP/IP must be installed on the computer.

12.1. Server: Port

Enter the address and port number of the PowCom server here on the format address:port. If a name-server is available symbolic names can be used for the address, otherwise the standard TCP/IP notation is used. Example: 199.200.110.101:4999 4999 in the example is the port number. PowCom only accept a port number higher than 1000 to avoid conflict with standards used in TCP/IP. The port number must be the same as the one the server use.

12.2. Get list

When an address and port number has been entered, pressing this button will bring up a list of systems connected to the server.



12.3. Connect

When one of the systems in the list has been selected pressing connect will set up the connection to that system. When connection is made the stored installation information on the system is shown and the system password have to be entered.

12.4. Cancel

Press cancel to leave this window without making a connection to end communication.

13. Com.port set-up

Select which comport should be used and the communication baud-rate. If an incorrect baud-rate is selected, direct communication will not work, while communication through modem may work. The baud-rate should always be set to the baud-rate the PCU uses. PCU 30.00 9600/4800/2400 baud (Default 9600) PCU 6.00 2400 baud PBSU 2400 baud PCU 3.00 2400/9600 baud (Default 2400) PCU 10.00 2400/9600 baud (Default 2400) PCS 2400/9600 baud (Default 9600)



14. Properties Message timeout

Message timeout is the time PowCom will wait for a reply before sending a new request. The default value is 1.0. In most cases this is ok, but when communicating via mobile phones, or over very long distances, or via radio modems or other equipment that cause a delay in the data flow it may be necessary to increase this time. In most cases 2.0 will be enough. If this timeout is increased it will take longer for PowCom to discover a broken connection. Values under 1.0 is not legal.

Dial up timeout This is the time PowCom will wait for a modem to set up connection with another modem. The default is 60 seconds. In most cases this is enough, but it may need to be increased if the remote modem has been set up to wait for many rings before answering.



15. Set parameters

Example for PCU 30.00

The number of functions available will vary depending on the particular system connected. Not all of the functions listed below will be available on all systems. Some systems have more than one output voltage. In this case the select rectifier window will appear prompting for a module or module group to set limits for.

Select rectifier Some systems have several galvanic isolated output voltages and the possibility for individual alarm threshold adjustment. Because of this feature the rectifier must be selected before the alarm adjustment can be made. However, when one module in a module group is adjusted the others will automatically be adjusted correspondingly.

Select U1 - U4 Select output mode for the system.. U1 is the normal charge voltage. U2 is the boost charge voltage. U3 is battery test voltage. U4 is a spare mode that may be used for a user defined purpose.

U1 - U4 Voltage reference for the different output modes.



Current limit

Gives the possibility to select a maximum current for the system. As battery current in amps. (PCS/PCU5/10), or as rectifier current in percent of maximum capacity(PCU30).

Low voltage alarm Adjusts the lower limit for voltage before the system gives alarm.

High voltage alarm Adjusts the upper limit for voltage before the system gives alarm.

Load/battery disconnection If the voltage falls below this limit during mains failure, the load/battery will be disconnected.

Partial load disconnect Disconnection of lower prioritised load in order to extend backup time for important load. Disconnection is time controlled or voltage controlled.

Load/battery connect If the battery is disconnected, it will be connected again if the voltage is above this limit and the mains returned. NOTE: Some systems do not include this function.

Temperature limit Sets the upper limit for temperature before the system gives alarm

Symmetry limit

If the voltage in one block differs more than this limit, from the average block voltage, the systems will give alarm.

End voltage battery test Lower limit for system voltage during test. If the voltage fall below this limit, the test will be stopped. An alarm will also be given.

Battery test time

Sets the maximum number of minutes a test may last. If this limit is reached the test will stop.

Ah. limit for test Sets the energy that may be discharged from the battery during test. If this limit is reached the test will stop



Number of batteries Sets the number of branches on the battery that are equipped with symmetry measuring.

Boost time Sets the duration of boost charging.

Boost interval Sets the number of weeks between each boost.

Boost factor Used to set the duration of boost after mains failure. See T1 LIMIT and T2 LIMIT.

T1 limit When the voltage reaches below this limit, the system starts counting time. When the voltage reaches over this limit again, the counting stops. The counted time is used in a function with the boost factor when the voltage reaches over T2 LIMIT.

T2 limit When the system reaches over this limit the boost will start. The duration will be the time from T1 LIMIT multiplied with the boost factor.

Over voltage shutdown If the voltage reaches over this limit, the rectifier which delivers the highest current will be switched off

High load Entered in percent of the maximum power from the system. If the load current get higher this limit, the system will give alarm to signal that there may not be enough capacity to charge the battery.

Test time Sets the time of day (0-23) when automatic test should start. E.g. 4 - the test starts at 04.00.

Automatic test Sets how many times each year automatic test shall be performed.

Battery type Sets the type of battery which connected. Indicates how many blocks each branch is divided into for symmetry measurements



Temperature compensating Activates the temperature compensation. The charging voltage will be adjusted continuously according to the compensation factor.

Compensation factor

The factor with which the charging voltage will be changed when the temperature compensation is active. The adjusted charging voltage refers to 20 degrees C. If the temperature rises with 10 degrees, the voltage will be reduced according to the adjusted compensation factor. If the temperature goes down the voltage will be adjusted correspondingly. The adjustment is done continuously, which means that if the temperature is changed with 1 degree, the voltage will be changed with 1/10 of the compensation factor.

16. Set date and time Adjustment of the internal clock in the PCU.

16.1. System time

Adjusts the time according to the time in the computer.

16.2. Set installation data

Change system information. This information will be displayed when connecting to the system. The information will not have an influence on the function of the system, but is necessary to identify the system. The values will be of interest to service personnel. The installation date should be set when the system is installed as it is used to calculate dates for battery tests.



17. Set system status (only PCU 30.00)

17.1. Control module active

Controls if the control module is allowed to regulate the output voltage of the rectifier modules. Should be active during normal operation. Will automatically be set "not active" at e.g. change of EPROM. The procedure is to adjust all parameters for voltage, alarms, levels etc. and then activate the control module.

17.2. Automatic boost charging

Sets the automatic boost charging (boost) active. Must only be activated if the batteries shall be boost charged.

17.3. Temperature compensating Activates the temperature compensation. The charging voltage will be adjusted continuously according to the compensation factor. 17.4. Compensation factor

Is the factor with which the charging voltage will be changed when the temperature compensation is active. The adjusted charging voltage refers to 20 degrees C. If the temperature rises with 10 degrees, the voltage will be reduced according to the adjusted compensation factor. If the temperature goes down the voltage will be adjusted correspondingly. The adjustment is done continuously, which means that if the temperature is changed with 1 degree, the voltage will be changed with 1/10 of the compensation factor.

17.5. Modules

Set the modules which are installed in the system. 1-31 are rectifier modules and 33 is the alarm unit (PAU). Tick off the installed rectifier modules. PAU (33) shall always be activated.

17.6. Automatic test (only PCU with lower software versions than 3.20)

States if an automatic test shall be executed once a year. PCU 30 with V3.20 or higher have several options for automatic test.



18. Transfer test data

The 10 last tests are stored in the PCU. The one closest in time is number 0, while the oldest is number 9. In this window you can fetch an optional test and see the data for the test (e.g. number of measurements, end voltage, max. symmetry voltage). If you find the test interesting, the data can be stored in a file and be studied in the VIEW TEST DATA window or a spreadsheet. Click Preview to get a preview of the curve. PCS only: If there was any batteries with symmetry measuring during the test the symmetry voltages may be downloaded by clicking the Symmetries button. If the button is grey no data is available. Symmetries may be stored as normal battery test files. The files for each battery is saved separately, with a filename, block numbers 1-4 is added to the name to produce the full name. That means that the filename for each battery should not be more than 7 characters.

19. Get all tests

Gets all tests stored in the PCU and saves them on disk. You can enter the name of a file or use the first seven letters in the type description, and 0, 1, 2,.. will automatically be added to the file names of the belonging tests. The test data can thereafter be studied in the VIEW TEST DATA window or a spreadsheet. If you do not know what is included in the different tests, this is mush quicker than getting one and one test from TRANSFER TEST DATA. If the filename you enter generates a filename which already exists, the old file will automatically be deleted.

20. Get battery log (PCS only)

Selecting this will open the above window which download the battery log data that has been stored in the PCS the first of every month. Press Download to collect the data from the PCS, this will take a while, and is indicated by a progress bar. Click Save to save the log as a tabulator separated file that can be imported in Excel, and other programs.



21. Change password

First enter your old password and press OK. If this is correct, you can enter your new password. Finally you will have to repeat your new password to avoid mistakes.

22. Alarm history

This windows shows a list of the last (up to) 40 alarms. By selecting a certain time in the list, the alarms that where active at that time are shown together with what change of alarm status occurred.

23. Alarms/information

The list shows all alarms that are active at the moment.



24. Module data

This window shows data about the active module. The layout of this window depends on the connected system. However, a scrollbar will always be displayed in the upper part of the window. This scrollbar is used to select the module. The number at the right side of the scrollbar, shows the selected module. The number which is stated as module no. (below the scrollbar) shows the module for which the data is displayed. If you select another module with the scrollbar, the data for this module will be displayed after approximately 1 second.

25. Alarm dial back

If needed the PCU/PCS can be set up to dial back to a certain number in case of an alarm. Tick off the alarms that should trigger a dial back. Enter the phone number, and enable dial back. Dial back require a modem connected to the PCU/PCS. Three modes of dial back is available. Server on change, is used



together with the PowCom phone server and the telephone number must be the number to that server. Note that this mode will dial repeatingly until contact has been made with the server, so do not use this in any other context. Pager on change will dial once each time the alam status change, ie also when alarms og away. Pager on new alarm will dial once when new alarms occur. To send a number to a pager set the phone number to NNNNNNNN@XXXXX , where NNNNNNNN is the number to the pager and XXXXX is the number that will be shown on the pager.

26. Set network address New versions of the PCU software allow several control units to be connected to one serial port controlled by a PowCom network server. For this to work each of the PCU's must be given a unique address. The address must be between 2 and 255.

27. Inventory (PCS only)

Will display a list of all modules and units in a system controlled by the PCS. Selecting a module or unit and selecting View Unit/Module Info will show more information about the selected item. The Reconfigure button is used when modules or units are permanently removed from the system to tell the PCS that all items that is not communicating has actually been removed from the system. Make absolutely shure that there is no items not communicating because of a failure before doing this.



28. Log data

If other data than battery tests are required from the system, this function can be used to log current, voltage etc. However, to use this function PowCom must be on-line with the system during the log period. The files generated by the logger, cannot be displayed in the VIEW TEST DATA window, but can be imported to a spreadsheet.

29. View parameter file Files saved by the save command in the SET PARAMETERS window may be viewed and edited offline by selecting this command. This way a parameter file may be altered and restored to the system at a later stage. The command open a standard set parameter window for the system type of the system the original file was created by.



30. View test data

This window displays test data graphically. Up to four charts can be displayed at the same time. Select the file you want to see from the file list. Ctrl.. together with the left push button on the mouse can be used to display several charts at the same time.

You can select the value of the axis by using the combo boxes marked with X-axis and Y-axis. The most interesting is voltage as a function of Ah-discharged. This chart is useful for comparing data for different tests to see if the battery voltage falls faster during discharging than when the battery was new.

To delete files use "drag-drop". Click on a file and drag it to the dustbin icon. The dustbin will open, and the file can be dropped into the dustbin.

The test data files which looks interesting can be saved by using the built in database function. Pull the actual file to the database icon and drop them in the same way as when deleting files.

To open a file in the database, double-click on the database icon. Thereafter select the files in the same way as in the file list.



To cancel the marking of all files in a list: Select only one file, push the Ctrl. button and click the left push button on the mouse over the selected file.

The list boxes which covers the graphic area can be moved by clicking the right push button of the mouse and drag the window, or hidden by deselecting LEGEND.

Print. By pushing the button marked PRINT a pop-up menu with the following options will be displayed:

Full page.

Printing the charts in the window in a full page version. The data for each chart is printed at the top of the sheet.

Half page

Printing the charts in the window on a half page. The data for each chart is printed at the top of the sheet.

U, A, Ah

Only available when one chart is selected. Prints voltage, current and ampere hours as a function of time in three different curves on one sheet.

Measurements

Prints the values of the test as text. Printer set-up

B baud-rate: speed. Can be 2400, 4800 or 9600 depending of type of modem and set-up

C call-back: modems can be adjusted in a way that when the modem has been called and when the correct password is stated, the modem hangs up and call back a programmed number. This is not a function which is available for all types of modems and some types of modem will not work together if this function is used. See the user manual for the modem for more information. If this function is used, it is possible to transfer a password and thereafter wait for the modem to return your call. clipboard: clipboard in Windows. Whatever is put here, can be pasted into documents in other programmes. combo-boxes: combo-box is a text area which shows a text together with a push button. When pushing this button a list will pop up below the text window, enabling the user to choose another option

1. General

The PowCom Network Interface is an embedded network server specifically suited to serve thePowec Power Supply systems (PPS5, PPS10 and PPS25). All the information gathered by either aPowec Control Unit (PCU) or the Powec Control System (PCS) will be available and accessible ona TCP/IP network.

Two methods for remote monitoring will be available in the first release of the PowCom NetworkInterface:

q Monitoring by using the PowCom Alarm Central and PowCom.q Monitoring over SNMP protocol (limited to SNMP Get and SNMP Trap).

2. Functional Specification

The Powec Network interface connects to the 9-pin D-sub connector in front of the PCU/PCSusing a null-modem cable. Ethernet is connected to the interface by using a standard patch cable withRJ45 plug.

When the unit is turned on it will automatically start to look for a PCU or a PCS connected to theRS232 interface. The control module will be available on the TCP/IP network as soon as the RS232communication has been established between the PCU/PCS and the Powec Network Interface.

A modem can be connected to a separate COM port on the Powec Network Interface. The modemwill function as backup communication in case of a failure on the TCP/IP network. The PowecNetwork Interface will break the communication with the PCU and let the modem communicatedirectly to the PCU if activity is detected on the modem COM port. The communication is switchedback to the Powec Network Interface when the modem stops to send data to the PCU.

2.1 Configuration of the Powec Network Interface

Initially network information such as IP address, Netmask and Hostname has to be specified. Theunit will primarily be set up with a static IP address, but a DHCP client can be provided ifdynamically allocated IP addresses are needed. The network interface can be set up with the correctnetwork information by using a small Windows program on a laptop computer. The computercommunicates with the Powec Network Interface over the RS232 port. The set-up program canalso check the network connection to the Powec Network Server by opening a connection over thecomputer network to the specified IP address.



New software version for the Powec Network Interface can be uploaded to the interface by using aFTP program. System diagnostics and troubleshooting can be done by connecting to the PowecNetwork Interface with telnet.

2.2 Supervision using PowCom and the Alarm Central

Supervision of the power supply system can be done anywhere from a computer connected to thecomputer network. The PowCom Alarm Central program can connect to many Powec NetworkInterfaces and can show the connected systems in a hierarchy of windows. Each system will have anicon that change colour and will give a sound alarm if the alarm status for that system changes.Detailed information for a specific system such as battery discharge curves, alarm history, symmetryvoltages and currents will be given by clicking on the icon and thereby opening a network connectionto that system with the PowCom program.

2.3 Supervision using the SNMP protocol

The first release of the Powec Network Interface will have support for SNMPv1 ”get” andSNMPv1 ”Trap” by using the Simple Network Management Protocol (SNMP). This protocol iswidely used for monitoring networked equipment where an SNMP Manager (i.e. HP OpenViewe)polls information from SNMP Agents in the network. The Powec Network Interface has anembedded SNMP Agent that will answer to SNMP ”get” requests for voltages, currents, systeminformation and alarm information. The embedded SNMP Agent will also send notifications calledSNMP Traps to the SNMP Manager if an alarm occurs. Traps will also be sent from each of thetwo external contact closure inputs. Six IP addresses for Trap Reciepients can be set both by theConfiguration program and by SNMP Set command.To get in-depth information about the power supply system and to be able to set parameters thePowCom program must be used. The ability to set parameters with an SNMP manager will mostlikely be added in future releases of the Powec Network Server.
