11 GGEENNEERRAALL IINNFFOORRMMAATTIIOON

XWEB 3000 is a Controlling, Monitoring and Supervising system based on “WEB server” technology. It is capable to communicate data to one or many external Clients with the same kind of procedure used by the Internet Web Sites. Clients need only a standard Browser such as Microsoft Explorer or

Netscape.

The XWEB 3000 server is mounted inside a 19” rack. On the back side, it is provided with the terminal connections for external devices (modem, printer etc.).

The Web Pages with all the information are contained into the server itself; Linux operative system ensures maximum efficiency and security.

The server reads, logs and checks the data coming from the Dixell instruments connected to a RS485 line. The communication protocol is the Modbus-Rtu. The XWEB 3000 is capable of recognising also most of the Modbus-Rtu compatible instruments not manufactured by Dixell.

ATTENTION: Always check the proper RS485 connections (see 2.1.1Check the rs485 before starting) ATTENTION: Dixell s.r.l. reserves itself the right to analyse the Modbus-RTU compatibility of other manufacturer’s devices before ensuring their integration into XWEB 3000 system.

Clients to Server connection possibility:

• Local: directly on the XWEB 3000 hardware, plugging in Monitor, Mouse and the Keyboard.

• Modem: point to point through local and remote modem devices (“Creating a Remote Access

under Windows”);

• Intranet / Internet: where available a static IP, using the standard socket 10 Base-T with RJ45 connector.

• Bridge network cable: You can plug a bridge network cable into RJ45 socket of XWEB 3000 and on the other side into your PC network adapter. Ask your network administrator to properly setup your PC to be able to access XWEB 3000 web pages.

The User interface is defined by the Browser program and it is the same for all kind of connections. The PC-client needs only a standard Browser, there is no need to install any kind of software Some of the pages created by the web server are dynamics and needs the Java Virtual Machine program that is normally installed in the latest Browsers and operative systems.

Check the different connection under “§ 2.1.5 Local connectivity” and “§2.1.6 remote connection from client PC”.

Features and functions included into the XWEB 3000 management:

• Data monitoring and recording, alarm detection and recording of the instrument connected.

• Alarm management defined by the User with visible signals, and remote transmission via Fax or

E-mail.

• Interactive commands to work with the connected instruments.

• “Run Time” function to show in real time all the information coming from the instruments.

• Parameter table programming.

• Graphic or table viewing and printing of the recorded data.

• Other service functions.

2.1 HARDWARE

ATTENTION: to protect both yourself and the computer from electrical hazards the XWEB 3000 should remain turned off until you are finished connecting all electrical devices to the unit.

To avoid accidental start of the unit, remember to plug in electrical cable only when you have finished setting up all other connection.

2.1.1 CHECK THE RS485 BEFORE STARTING

To be connected to the serial line all the Dixell Modbus instruments must be provided with direct RS485 terminals or the “TTL”-RS485 interface (XJRS485 or XJ485). Check the instrument manuals for more information. The RS485 line is mainly based on two polarised terminals. Please pay attention to respect the right sequence for all the devices connected to the serial line.

Follow these important advises:

• The RS485 serial line must reach all the instruments where they are installed.

• Pay attention and respect the wire polarities when screwing them into the instrument terminals.

2.1.2 EACH INSTRUMENT IS PROVIDED WITH THE ADDRESS PARAMETER

ADR

• The cable must have 2 or 3 wires with shield, minimum section 0,5mm2 (eg. the BELDEN 8772).

• From the XWEB 3000 position the cable reaches all the instrument positions.

• Do not execute loops or derivations:

Right connection

Page 12

XWEB 3000 – rel.1.0 –

Wrong connection

• Always keep the serial cable away from power cables.

• Always keep the serial cable away from electro-magnetic or frequency sources.

• Do not connect shield to ground.

• Do not connect the “Gnd” terminal.

• Remember to draw a map of the line. This will help you to find errors if something is wrong.

• The instrument with RS485 have “+” and “-“ terminals, respect the polarity.

• To keep the line balanced it is necessary a 100 Ohm resistor at the end of the line (you ca use the

RS 485+ and RS 485- terminals of the last instrument connected).

2.1.2.1 THE TTL OUTPUT

• The instrument with RS485 on board do not need any kind of external interface module.

• For instruments with external interface: keep the TTL cable away from power cables or frequency

sources.

• The XJ485 external interface must be connected with TTL cable to the instrument with TTL compatibility.

2.1.3 SERIAL ADDRESS OF THE INSTRUMENTS

• Each instrument must be defined by its unique address.

• Check the address into the Adr parameter value. Take reference to the instruction manual of the

instrument itself to find the right procedure to enter the programming and set the value.

• The easiest way to work with the category functions is to set the addresses progressively for similar groups of instruments which have the same application.

2.1.4 COMPATIBLE INSTRUMENTS

2.1.5 LOCAL CONNECTIVITY

2.1.5.1 LOCAL CONNECTION WITH MONITOR, MOUSE AND KEYBOARDRD

On the back side, the XWEB 3000 is provided with the sockets for a monitor, a mouse and a keyboard. Please connect all the peripherals before powering-on the unit otherwise the system may fails to recognise them. This means that , for example, if you do not plug the monitor cable now, you won’t see anything displayed on it. The unit can also work without these three elements therefore if the user intend to work just with the remote, he can definitively remove them after the setup operations. In any case inside XWEB 3000 is loaded a standard browser to allow the user setting up the unit. If necessary check the instructions manual of each device connected to the unit.

The operative procedure to work with XWEB 3000 is the same for all connection method.

2.1.5.2 LOCAL CONNECTION THROUGH PERSONAL COMPUTER

It is allowed the local connection with a single PC, provided with LAN card, by using the net connector RJ 45 (LAN). Due to the PC-client power, this kind of connection is more suitable for the setup procedures.

Remember that the PC must be provided with internal LAN card or external adapter for LAN. IMPORTANT: the cable between the Server and the PC must be with crossing wires (“Bridge Cable”). The connection procedure from the remote PC is made simply by launching the Browser program and inserting the default address of the XWEB 3000 unit http://192.168.0.200 into the address bar.

2.1.6 REMOTE CONNECTION FROM CLIENT PC

2.1.6.1 MODEM CONNECTION (“OR POINT TO POINT CONNECTION”)

It represents the most common method where the LAN (intranet / Ethernet / internet) is not available. It is strongly advised to use a dedicated telephone line.

IMPORTANT: Use exclusively modem devices approved by Dixell.

Remember that many modems are not compatible with Linux.

The list of compatible models can be found under the menu: Configuration – System - Modem. USB Modem (recommended).

Page 14

XWEB 3000 – rel.1.0 –

Connect the USB Modem to the USB Port on the back side using the modem cable commonly included into the modem packaging itself. There is no need to give power supply to the modem because the Server provides it through the USB port. The modem reset is directly controlled by the XWEB 3000 Server through the USB port by turning off and then on the modem device. Connect the modem to the telephone line with the phone cable included into the modem packaging. Remember to check if there is a switching machine. The connection procedure is divided in two parts: In the first part it is necessary to create the Remote Access, in your remote PC, set with the telephone number of the line where the XWEB 3000 is connected to. You have to use Dixell as Username and Password. The second is the procedure you will ever use: after launching the new Remote Access that will engage the line through the modem, start the Browser from your PC and insert the address http://192.168.1.200 into Explorer/Netscape address bar.

2.1.6.2 INTRANET / ETHERNET CONNECTION

The Intranet or Ethernet connection should be initially managed by the net administrator which will assign one free IP address to reach the Server. This number is an example of what you should expect:

http://192.168.000.111.

After receiving the address from your network Administrator the XWEB 3000 must be set with this number. REMEMBER: A setup wizard will guide you through the procedure. Please ensure you have an IP address to use in network section. Use a standard RJ45 network cable to connect the unit to your lan.

The Intranet method allows the connection to interact with XWEB 3000 from all the PC Clients. Insert the net address assigned by the administrator into the Browser address bar. Bookmark the address with personalised name for the future connections.

2.1.6.3 INTERNET CONNECTION

It is necessary a STATIC IP address for the XWEB 3000 which is normally assigned by the Provider of your internet services (ISP net). The Internet connection allows XWEB 3000 to be reached from all PC-clients. Insert the net address assigned by the administrator into the Browser address bar. Bookmark the address with personalised name for the future connections.

Ask your provider for more details about the rent of a the static IP. This the internet system requirements for the best result:

• Wide band connection.

• At least 1 static IP addresses for the XWEB 3000.

The internet connection is established through a device called Router that receives and sends the data as interface between an Intranet and Internet. The Provider also assigns the address of the router that is called IP WAN.

Remember that the default value of the IP of the XWEB 3000 is: 192.168.0.200. Depending on the contract the Provider can also supply the router, otherwise the user can buy it

separately.

Page 38

XWEB 3000 – rel.1.0 –

REMEMBER: ask qualified personnel for the router installation by using these information: Used ports that are mapped to the LAN side:

• 80 (used for the http:// access)

• 22 (used for SSH connection)

• 443 (used for SSL protected connection)

• 10000 (used for the internal modules of the system)

The above ports are all related to the XWEB 3000 IP address 192.168.0.200. While the ports on the WAN side are:

• Telnet (to configure the router from a remote, also via Internet)

• http (To access the XWEB 3000)

If working with the router GATEWAY and DNS check your Internet contract details.

2.2 CONFIGURATION

2.2.1 XWEB 3000 ACCESSES AND CONFIGURATION

Before turning on the XWE3000 read these notes.

• The User interface is the same for all kinds of connections, therefore it does not matter if you are a Local, Local PC, Intranet or Internet client for the setup operations.

• The local access with PC is the fastest way to work with. Be sure the Pc-clients are provided with Java Virtual Machine. Launch the Browser and insert the default address 192.168.0.200. Ask your network administrator to avoid IP number conflicts.

2.2.2 CONFIGURATION SYSTEM

The on/off switch is on the back of the unit. Press the bottom of the switch (marked with I ) to turn the server on, immediately

the led marked with Power turns on. For few minutes the Server starts loading the operative system, the local monitor shows the loading messages of each system while the HDD led (hard disk) is blinking.

After the first loading of the operative system, you are required to setup the unit by using a Wizard program. This wizard will appear only during the very first power-on of the unit.

The first windows asks you to log-in to the system. Use Admin as “User name” and “password”.

Before proceeding please notice that in the right side of the fields that you will see during setup procedure there is a question mark. By clicking on it a pop-up windows with a contextual help will appear. The first windows ask you to choose your language and keyboard layout:

Page 40

XWEB 3000 – rel.1.0 –

Now choose a proper name for the unit. You can use two data fields: “System name” and “System description”. We strongly suggest that you always use the same criteria. This will help you to manage more than one XWEB.

Page 41

XWEB 3000 – rel.1.0 –

Next windows ask you to adjust real time clock of the unit, moreover you have to choose your correct time zone. There are 25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England. Some countries have adopted non-standard time zones, usually 30 minutes offset. Each Time Zone is measured relative to Greenwich, England. By setting the right Time Zone the system will be able to calculate the local time independently on the Client calling Country.

Page 42

XWEB 3000 – rel.1.0 –

Next window allows you to setup the network. You can choose “No network”, it means you will not be able to reach your XWEB 3000 using intranet/lan access. This is an uncommon situation. On the other side if you ckeck the radio button “fixed network”, you have to fill in the blank labels. We suggest you, before proceding, to contact your network administrator to get help. IP ADDRESS: you need this unique number to identify your XWEB 3000. There are 2 kind of IP numbers: private and public ones. The first are usually used to setup an intranet/lan where all clients do not need to be reached from outside. We can compare this situation to a close enviroment: communication is possible only between IPs belonging to this private range. For example IP numbers

192.168.xxx.yyy define a private network.

NETWORK MASK: is just like a filter, 255.255.255.0 means XWEB 3000 can directly reaches only PCs belonging to its IP range. All other requests will be send to a valid gateway. GATEWAY ADDRESS: You have to compile this field with a valid gateway IP number. Gataway machines are a kind of portal through which all data that can not directly reaches the target IP directly, are sent. PRIMARY/SECONDARY DNS: In the internet world you can reach a web server using its name, for example www.dixell.com, digiting the name into your web-browser address bar. Due to the protocol used to guarantee performance and security, all names are converted into IP numbers. This operation is made by a DNS server. Usually your ISP or your network administrator can provide you a valid DNS number. EXTERNAL IP ADDRESS: Is the uninque public IP address assigned to the XWEB 3000 Server on the Internet network. This Address will be used by people on the Internet to access to the server. Please contact the Network Administrator for this parameter.

Page 43

XWEB 3000 – rel.1.0 –

Next window allows you to setup the modem connection. XWEB 3000 uses the modem to send faxes and in same cases also e-mails. In the first case the unit itself can send a fax, while in the second case you may need to setup a dial-up connection (next step). Please remember that only modems approved by Dixell can be used. We have 2 different kind of modem: serials and USB. You can get more info and ordering codes reading APPENDIX D.

Page 44

XWEB 3000 – rel.1.0 –

If you have setup a modem type, next window ask you to setup a dial-up connection. It may happen that XWEB 3000 is directly connected to an intranet/lan but the unit (due to the network topology) can not reach a valid SMTP server (read e-mail setup in this guide). In this case may be useful to make a temporary internet connection using the modem. You need a valid internet account, with the telephone number of your ISP, log-in name and password. In case of need XWEB 3000 will make a call to the ISP and send the e-mails.

Page 45

XWEB 3000 – rel.1.0 –

In the next step you have to configure e-mail. One of the most versatile way to communicate alarms to the outside world is using e-mail services. Nowadays e-mail messaging system is a world wide way of communicating and sharing information between people. XWEB 3000 can handles e-mail, but to send them you need to make a proper setup of the unit. There are 2 different routes that XWEB can uses. The first way, if it is present, is using intranet/lan connectivity. This means that a SMTP server must exist and XWEB have to reach this server through the lan. In this case gateway and DNS parameters are mandatory in “Network Configuration” window. The second method is used when there is no direct lan access to internet. In this case a modem is needed, Xweb 3000 will contact directly your ISP provider and using its services will send all the e-mails. To send e-mail you need a valid SMTP server. Usually your lan administrator will provide you a server name, for example dixell.com (another format widely used is mail.your-company-name.com), then a valid e-mail address is needed. We strongly suggest you to create a new e-mail account to use with XWEB. In this case, e-mail header will be something like this: xweb@your-company-name.com. This is very useful to apply e-mail filtering in the client PC. Is not necessary to have a dedicated mail account to use e-mail services, but is strongly reccomended because for example many SMTP servers need user account authentication (especially ISP) and in this case without a proper user you can not send e-mails.

Page 46

XWEB 3000 – rel.1.0 –

Next window allows you to setup printers. Pay attention that if you use “windows network printer” the right syntax is //PC_NAME/PRINTER_SHARE_NAME. It depends on your network topology, ask your network administrator.

Page 47

XWEB 3000 – rel.1.0 –

Now you are at the end of the procedure, a summarising windows will appear. Check if all values are correct then click-on “confirm”. At this point the system is going to restart. You have to wait some minutes to be able to log-in again.

Page 48

XWEB 3000 – rel.1.0 –

For future uses you can come back to the setup window, first you have to stop the modules, then go to the “System” menu. By clicking the proper label on the left side of the window, you can go back to the setup menu you need.

3.3.2.8 CALENDAR FUNCTION

The Calendar function is used to define if a function or a single event is active or not in the selected period of time. Therefore the Calendar is suitable to include/exclude certain period of the day, month or year when it has to interact with some XWEB 3000 procedures or for instance if the maintenance personnel is working on the unit. The resource (or any programmed procedure that the XWEB 3000 has to follows) related to a Calendar is available “Enabled” only during the selected periods otherwise it is “Disabled” and it does not work. The XWEB 3000 use the Calendar as filter before activating the resource itself, if the resource is not Enabled in that period nothing happens. The alarm procedure to inform an Assistance Centre or the light on function can be override by their appropriate Calendar programming. The number of Calendars is not limited and each Calendar can manage more than one resource. The Calendar is based on a weekly list extended for all the month, the tile colour shows the function related to that day

The day are divided in:

• Enabled à Green colour;

• Partly Enabled à Yellow colour;

• Disabled à Grey colour.

Disabled day represent the 24 ore where the resource is not active (eg holiday). Enabled and Partly Enabled days can accept the period of activity of the resource.

• Setting the daily period activity for all the week

(Eg: define Saturday and Sunday as Disabled, Wednesday as Partly Enabled).

Select the appropriate month: Point the mouse arrow on the rose tile “Saturday”. Click with the left button and then set the value as “Weekly not Enabled”. The tiles become Grey.

3.3.3 ALARMS

3.3.3.1 ALARM TYPOLOGY AND ALARM LEVELS

The alarm typology is a list of alarm events designed by the user to describe the possible alarms that the instruments can generate. In this way similar alarm events can be grouped together under a unique identification label, so high

Page 64

XWEB 3000 – rel.1.0 –

and low temperature alarms can be defined as “Temperature alarms” or the high and low pressure alarms belong to “Pressure alarm” identification. The Alarm Level list is also designed and named by the user. Each alarm level can be assigned with one or many alarm typologies. The alarm levels starts the appropriate action in case of alarm event and depending on the level of alert it transfers the information via fax and e-mail with appropriate messages or turn on relais etc.

3.3.3.2 DESTINATION OF THE ALARM MESSAGES

The list of the destinations contains the users (directors, maintenance personnel, assistance etc.) enabled to receive the alarm notification. The XWEB 3000 is capable of transferring the alarm message through Fax, voice message or e-mail.

• To insert a new item Click into the field “Name” and insert the appropriate word or words. Click on “Insert” to add the new voice.

• To change the setting Click into Selection and find the desired item from the list. Click into the desired fields and change them with the appropriate values. Click on “Modify”.

• To delete an item Select the user to delete. Click on “Cancel”.

• To delete all the items of the list Click on “Cancel All”; Confirm the operation if necessary. Wait the screen refresh.

• To reset the form Click on “new”.

For each receiver the calendar function is also suitable to enable the alarm sending procedure only during certain period of time. See Calendar chapter.

Page 65

XWEB 3000 – rel.1.0 –

3.3.3.3 ALARM LEVELS

The alarm levels are organized as a list of items. Each named level provides to execute the right procedure to transfer the alarm notification to the receiver or receivers. They act just like a filter Eg: an alarm belonging to the “Temperature alarm” typology can be differently treated from the “nolink” alarm so as the destination and the kind of message are suitable to a proper information about the alarm event itself.

The alarm level also assigns the number of receivers and the transmission mode (Fax and E-mail). The easiest method to work with levels is to define three kinds of alarms corresponding to “Severe

alarm”, “Standard alarm”, “Warning”. Each alarm typology, depending on its importance, can be linked to one of this three alarm level to alert different personnel.

It is also allowed to define as many alarm levels as the existing alarm typology in order to transfer a complete information about each alarm origin.

Under the device configuration paragraph you will learn how to assign the designed alarm typologies and alarm levels to each instrument. This multilevel structure gives the maximum flexibility and it comes to solve every kind of alarm management problem.

• Insert a new Alarm Level and the attributes Click into “Name” and insert the word(s) that better represents the alarm eg: ”Severe Alarm”.

• To insert the Receiver Select the Receiver. Click the kind of procedure to send the alarm (Fax, E-mail). Click on “Insert” to add the new item.

• To modify an item

Select the item from the “Selection” roll down menu. Modify the appropriate fields. Click on “Modify”.

• To delete an item Select the user to delete. Click on “Cancel”.

• To delete all the items of the list Click on “Cancel All”; Confirm the operation if necessary. Wait the screen refresh.

XWEB 3000 – rel.1.0 –

• To reset the form Click on “new”

3.3.3.4 ALARM TYPOLOGY MANAGEMENT

The alarm typology list, designed by the user, groups the common alarm features of the instrument into an unique definition. For instance all the temperature alarms that are not important can be defined by a typology named as “Normal Alarm” while the temperature alarms of the frozen food can be identified by the typology “Bad Alarm”.

The user can assign a typology name for the desired alarm event such as: High temperature, low temperature, High or pressure, open door, compressor oil, Frozen food, Bad alarm Etc…

The user can define the accuracy of the alarm description Each typology can define the following:

• One of the alarm level previously defined to send the alarm.

• The Accumulation time that represents a counting period of alarms to reduce the number of

alarm reports which contain the list of alarm events.

• The Delay time that define the minimum period of alarm, if the alarm must be longer to be

computed otherwise the system does not take any action.

• For each method the user can insert the appropriate word or the words that represents the

alarm transmission.

• To inset a new Alarm typology

Click into the “Name” and insert the appropriate word or word to describe the alarm tipology. Assigne the alarm level procedure under “Level”. Define the “Accumulation” time and the minimum activation time or “Delay” of the alarm. Insert the appropriate message header into the corresponding fields.

• To modify the item

From “Selection” find the desired item. Change the wrong description. Click on “Modify”.

• To delete an item Select the item to delete. Click on “Cancel”.

• To delete all the items of the list Click on “Cancel All”; Confirm the operation if necessary. Wait the screen refresh.

• To reset the form Click on “new”

3.3.4 DEVICE CONFIGURATION

The configuration of the devices allows to assign the appropriate monitoring system attributes. The configuration is subordinated to the manual or automatic search procedure to create a list of the available instruments. For each kind of instrument the XWEB 3000 will show only the peculiar information of instrument itself and the attributes of the available digital and analogue inputs of the instrument. Only this part of configuration admits the association of the categories previously defined such as the alarms, the commands and functions. If during the configuration it is necessary to use a category to associate to a new feature of the instrument but the category it is not present, the user can step back into the Categories menu, create the new category and then restart with the device configuration.

• Select a Device From the Selection roll down menu find the appropriate one. If the instrument has not been already renamed the identification name will be: “xxx xxx_New_Model” where:

• xxx represents the serial address of the recognising procedure (Adr parameter);

• “New” means that the name is still unassigned;

• “Model” define the instrument model.

Instead of the string “xxx_New_Model” the user can insert the new appropriate name of that instrument.

Page 68

XWEB 3000 – rel.1.0 –

• Assigne the device name

After selecting the device, click into the “Name” field. Insert the new name such as “Frozen food_001”. Click on “Confirm”, even if you can do it just before exiting the configuration.

• Assign the category to the device “Device category setup”

Be sure of having selected the right instrument under the “Selection” field. Depending on the instrument model there are different available categories to define the attributes of the instrument itself, If you do not find the right one maybe it is not defined or it is not available for that instrument. By itself Xweb 3000, after the recognising procedure, assigns the default categories (if you checked the box in category window) to the devices connected to the RS 485. To change the category click inside the field and select the appropriate item. Click “Confirm” now or at the end of the whole configuration.

• Assign the Alarm Typology

Be sure of having selected the right instrument under the “Selection” field. ALARM ORIGIN: depending on the instrument model there are different available alarms, if you do not find the right one it means that it is not available for that instrument. LABEL: each alarm can be assigned with an appropriate label defined by the user, this label is also used when it is displayed by the system.

Page 69

XWEB 3000 – rel.1.0 –

ALARM TIPOLOGY: links alarm type to the proper Alarm typology. If you do not find the proper action in it, step back to the Alarms definition to insert the new features into a new alarm typology. THIS FOR ALL DEVICES: by clicking this button you can set all the instrument with the new values. The alarm configuration obtained is repeated for all the instruments having this compatible field.

SND (Send): when enabled the alarm is treated also to be sent. REC (Recording): when enabled the corresponding alarm is logged.

Click “Confirm” now or at the end of the whole configuration.

• Define the digital, analogue inputs and the status

The lower area is dedicated to the analogue inputs (probe), digital inputs, digital outputs and status assignments. NAME: The first time each name is displayed by following the internal XWEB 3000 archive of standard feature of the instruments. Each definition can be renamed when necessary to give the proper meaning. Udm: The analogue input is followed by the proper unit of measurement, change the unit by clicking in it then insert the new value. Pay attention that in this window you can change only the label of the unit of measurement. In Advanced section you can change the behaviour of the instrument (e.g. Celsius or Fahrenheit degree)

Read: when enabled the value is computed and displayed. Save: when enabled the value is logged.

Click “Confirm” now or at the end of the whole configuration.

• Delete one device from the list From Selection find the instrument to delete. Click on “Cancel”.

• Advanced function The “Advanced” key allows to reach another configuration area dedicated to the instrument setup. This area is very dangerous because this configuration defines important features that can badly affect the result if not properly set.

XWEB 3000 – rel.1.0 –

Take care of this advise and ask authorised personnel before trying any kind of setting. You can find the more complete information in Appendix A.

3.3.5 XWEB 3000 ARCHIVES

You can access data information from the roll-down menu “Devices” The data archives are organised in two separate structures:

• Main archive

• Circular archive

Main archive is a file containing all the instrument data recording, the time interval used for these recordings is defined into the category “Recording interval”. This archive grows time by time depending on the number of instruments and it can become very large occupying the available memory contained into the server Hard-disk.

Circular archive are independent and reserved to each device. They are in FIFO format (First In First Out) and the maximum duration is 48hours. Under this archive it is possible to explore only the last 48 hour of the whole information recorded before the date/time of the request. The circular archive logs data with a very short interval time, faster than the main archive so as the data consulting can reveal much more information of the functioning status. This sampling time depends on the number of instruments connected to the RS485 and the number of the resources recorded.

Page 71

XWEB 3000 – rel.1.0 –

The home page of the system show the average cycle time to complete the reading of the whole instrumentation connected to the XWEB 3000. This time is pretty equivalent to the sampling time used by the circular archive log function.

The circular archive is deleted if there are some changes into the setup of the instruments.

3.3.6 DEVICES

3.3.6.1 DISPLAY INFORMATION OF A DEVICE

Select SINGLE VIEW to show all the data corresponding to a selected instrument. You will be informed about probe values, digital inputs, device status, alarms for all the time you are connected.

Page 72

XWEB 3000 – rel.1.0 –

• How to select a device and show the data

The devices can be selected using the Typology filters in order to reduce the number of items of the search. From the “Device Typology” roll down menu select the category to which the instruments belong to. Then, under the “Select a device” menu select the instrument you are interested in. After some seconds the whole situation of the instrument will be loaded and displayed. The information are divided in horizontal rows such as analogue inputs, digital inputs, output status, alarms, commands. A grey label means a function not available for this particular instruments.

Remember that you are looking at a static page therefore the instrument information are loaded and displayed then there are no more data coming from the server. The screen refresh with the new data can be executed automatically by selecting the “Auto” box and decide the updating interval by clicking into the time box on the right side. Click on “Update” button to update the window with manual procedure.

• Change set point function You can change on the fly the set point value by clicking inside the box:

A window will appear, asking you the new value, confirm the new set point clicking OK button.

Page 73

XWEB 3000 – rel.1.0 –

• Commands The last row of information contains the available commands for that instrument. Use them to operate on the instrument. Take care of the operations you make with commands.

Click on the interested function button, after sending the command the information of the new status will be automatically updated and displayed.

Pay attention that “Stand By” commands turn off the instruments.

3.3.6.2 DISPLAY THE GRAPHS

The graph structure and the procedures are the same both for Circular Graphs recordings and Main Graphs recordings .

• Select which instrument value to show From the “Devices” menu, select if you to display the “Main Graph” or the latest 48 hours or the “ Circular Graph”. Then, select the desired device from the filter lists of the Device typology and the device list. After selecting the instrument, the screen will show all the available data which the instrument is provided with.

Page 74

XWEB 3000 – rel.1.0 –

The first information about the archive shows into “Available Interval” the first and the last recording date, while the “Select Interval” includes the period you have decided to show. If necessary, modify the Select Interval period.

Longer is the time interval to show, longer the loading time needed to show the data graph. For a first analysis select a time period not very wide but centred on the target of your interest, this ensure higher graph precision. You can also act on “Graph Density” parameters to decide if you need all data samples. This feature is very useful if you are connected via modem at a slow speed.

You have 3 main rows: Analog – Devices Status – Devices Output. For each of them you can graphs as many values as you want. The only limitation is 3 analog values and 2 digital ones.

For each selection is possible to decide the colour of the line that will be represented. It is also possible to group the analogue inputs into a unique graph or to display them into separated ones. For example if you want to display all data using only one graph, select for each value AG1 from the roll-down menu, then in “Graph labels” write some words reminding you the meaning of the graphs. On the other side if you want to display the values in different graphs, you have to chose AG1 for the first values, AG2 for the second and AG3 for the third. Remember that each graph can be renamed by the user with an appropriate name into the corresponding “Graph Labels” situated into the low side of the page.

Before clicking the command “Show Graph” it is possible to define the graph density to decide the resolution of the lines and recordings. Select the box “ Graph Density”. Higher is the value of this parameter better will be the graph resolution, but longer the downloading time from the XWEB 3000.

Now Click on “Show Graph” to start the transferring process of data from the XWEB 3000 to your console.

The displaying structure is based on a Java Applet and the Java Virtual Machine program installed into the remote PC that computes the data coming from the XWEB 3000. Depending on the Virtual Machine version installed a message to accept the term of use will appear during the operation. Dixell s.r.l. guarantees that the software is free from viruses and the request can be accepted.

Page 75

XWEB 3000 – rel.1.0 –

The counter signals shows the status of the data you are downloading

At the end you will see the built graph.

• Zoom in/out procedures Before executing the zoom it is necessary, if there is more than a graph displayed, to select the desired graph. Click, with the left button of the mouse, into the top bar of the information of graph itself. To zoom in you just have to keep pressed to left mouse button. To zoom out you just have to keep pressed to right mouse button

• Zoom into an area

To enhance the portion of a displayed graph click and keep pressed the left button of the mouse on the hypothetical top-left corner of the area to zoom. Than drag the mouse down to the low right corner to complete the window to zoom. If the selected area have not the proper dimensions click one time outside the area itself to abort the zoom, then repeat the operation to select the area to zoom. Otherwise, if you click one time with the left button inside the selected area, immediately this area will be zoomed to the borders of the graph.

• Back to the original size

To resize the graph to its original dimension select from the “Scale” menu the “Reset Size” option.

Page 76

XWEB 3000 – rel.1.0 –

• Manual Scale The first time the graph is displayed with an “auto scale” function defined by highest and lowest peek and the whole interval time selected. Do define a personal scale of the graph view select from the “Scale” menu the “Manual Size” item. The next windows will show the X and Y scale limits that the user can adapt to his requirement.

• Graph Synchronism

When a instrument information are displayed into 2 or more graphs, all the horizontal time axes are synchronised together. By zooming only one of the graphs the result is that the other are no more synchronised with the new time base. To keep all the graph synchronised you can use the “Sync” function from tools menu Select it for each graph that has to be included into the synchronism function, then zoom into one of them. You can notice that all time axes are now synchronized.

Note: the synchronism function adapts the others graph to the zoomed graph. Therefore, if you intend to synchronise the other graphs with “Tools - Sync” remember that the last one selected must be the zoomed one.

• Graph info The graph information area is immediately displayed with the graph itself. If necessary move or drag it where it does not cover part of the interested area. To close the information window click on its crossed button. To make it appear again select “Legenda” from the “Tools” menu.

• Save a graph format

This function provides to save the data of the displayed graph into the hard disk of the client computer connected to XWEB 3000.

To start the operation select “Save” from the “Tools” menu. After that you can proceed by using the typical saving method of Windows operative system, remember to assign a proper name and origin of the data.

• Load a saved graph This function loads the data of a graph that was previously saved into the hard disk of the client PC. To start the operation select “Load” from the “Tools” menu. After that you can proceed by using the typical opening method of Windows operative system, select the proper name.

• Print a graph To print a graph on the printer of the client PC or on another net printer, select “Print” from the “Tools” menu, the follow the typical Windows structure.

• The background colour of the graph The background colour of the graph changes depending on the status of functioning of the system in that period of time recording.

Page 77

XWEB 3000 – rel.1.0 –

White background, for instance, defines a normal period of functioning and data recording. Green background means instrument off Grey background means instrument no-link (it does not communicate) Rose Background means system recording stopped. Check the assignment of the colour function under “Background” from the “Help” menu.

3.3.6.3 PARAMETERS

The Parameter function allows management of the parameters of a selected device. The parameters can be displayed and modified.

Click on “Upload” to proceed.

• To print the displayed map Click on “Print” from the “Action” menu. Use the message box to select the print properties. Confirm the printing to proceed.

3.3.6.4 RUN TIME

The run time function provides to display into a unique window many devices together. This is dynamic page and the data showed are updated in real time (the period depends on the number of instruments).

This page based on the modern Java programming language, therefore it is necessary to have the Java Virtual Machine installed on the client PC. Normally the JVM is already installed into the PC operative systems, (if not present see Minimum requirements section in this manual) a warning message will propose you to use it. Accept it, the software applet is guaranteed free from viruses.

• Start the Run Time From the Home page select the “Run time” from the “Devices” menu The first part is referred to the selection of the Category of the devices installed in order to save loading time, while the selection “All” will show all the instruments.

After selecting the proper category, XWEB 3000 begins sending data to your PC. The first time

Page 80

XWEB 3000 – rel.1.0 –

you load the RUN-TIME windows, you are requested to accept the start of JVM program. All applets that use JVM are certified by Dixell. Please answer to the warning windows by clicking on the “OK” button (the message text depends on the release of JVM and on operative system of the PC) Then the Run Time page will start to display the selected devices with their information. If one or more instrument have an active alarm event, the message box will indicate the alarm situation with a red “Alarms” label. If whole situation of the instrument displayed is normal, the message box will show “Device(s) OK !” in green colour.

Each device is represented by an horizontal row that includes as many rows as many information are available from the instrument. For each row, the blue bar contains the address and the instrument name followed by the typology to which the instrument belongs to. At the end of the blue bar there is the command box “Sel”. The second row of a main row contains the setpoint and the analogue inputs like the probe values or other peculiar information of the instrument read-outs such as the electrical measurements of a net analyser. The third row of a main row is divide in three parts: the first area contains the icon symbols of the instrument status, the second area contains the icon symbols of the instrument outputs (relais) and the third area shows the digital input status with their complete description. The icons and the description coloured in light grey tonality represents the corresponding function as not active. The active status of a instrument function is represented with the corresponding blue icon.

More information about the icon function can be red, pointing the mouse arrow over a single icon, on the left down corner of the browser border. A brief resume can be found in Appendix C.

• Devices in alarm In case of alarm event the corresponding instrument is signalled with the red blinking description.

Page 81

XWEB 3000 – rel.1.0 –

Immediately also the message box, on the top of the browser bar, will indicate the alarm situation with a red “Alarms” label.

Find the complete alarm description clicking on the row blue bar. A pop up message box will appear, inside you will find the list of the actual alarms that also includes the starting date of each event.

• Send the commands to devices From the run time page you are allowed to interact with the instruments by sending commands to them. The user is requested to select the instrument or the instruments to which the command has to be sent. To do that click into the “Sel.” box to select the instrument.

On the right top side of the browser border will appear a Toolbar which contains the Commands button and the possibility of selecting or deselecting all the instruments together. To define the command to send click on “Commands” and immediately a choice list will appear. For multiple selection of some or all instruments the available commands will be only the common commands among the instrument selected. Select the command and click on “Send” button. Before proceeding a message box will tell you how many instruments are involved.

Page 82

XWEB 3000 – rel.1.0 –

The popup box also shows, with a blinking message, the status of the operation just executed and then also the ending report result. If an error occurs the corresponding diagnostic message is displayed.

XWEB 3000 – rel.1.0 –

3.3.7 ALARM MENÙ

3.3.7.1 HYSTORICAL ALARMS

This function shows you all the alarm events detected from the XWEB 3000 system. It is also possible to setup a search filter.

• Alarm view and filters To enter the alarm view, from the Home Page, select “Historical” from the “Alarms” menu.

The Device Alarm Page is divided onto 3 main section: device search filters, alarm typology and time period.

The “Alarm Filter” defines which alarm level and which kind of alarm to search.

The “Device Filter” defines the typology and the name of the instrument to search.

Push “go” button to load the page.

Page 84

XWEB 3000 – rel.1.0 –

The “Time Filter” sets the period in which the search is restricted, the user can decide the last back period from the date of the connection, in this case the default is the last week while it is also possible to define a specific window into the alarm archive with the “From … To” selection. All the selections can work together at the same time. To start the alarm search click on “Go” button. It is situated at the right end of the browser border. The alarm description is displayed in table format.

Pay attention to the status of an alarm:

Active (To column): Alarm is still active Auto (ending column): Alarm stopped automatically. It means that alarm event is now ended. Systop (ending column): Someone has stopped the recording activity Restart (ending column): System has been rebooted by someone/something.

• Actual view of a device included into the alarm list The user could be interested in having more and deep information about the actual situation of an instrument with an active alarm that is included into the alarm list. That’s why if you click on the description of the instrument itself the XWEB 3000 will load the specific page of information of that instrument. When finished close the window blinking the crossed box on the right top corner to come back to the alarm page.

• Print the alarm list Select the “Print” from the “Action” menu situated on the left corner of the alarm page under the Dixell logo. Use the structure of the operative system of your client PC to select and configure the printer then proceed with the printing.

Page 85

XWEB 3000 – rel.1.0 –

3.3.8 PRINTING

Before proceeding please verify to have chosen a printing method under “Configuration”-“System” rolldown menu.

You have to choose a device, then a value you want to print. Finally define time interval and push “go” button.

As you can see the printing format is very narrow, each sheet may contain up to 7 column. Each column is divided into 2 data fields: time and value. Day change is remarked in blue colour. Recording interval (2 red arrows) is the one set in “category” -“recording interval”.

Page 86

XWEB 3000 – rel.1.0 –

3.3.9 PERMISSIONS

From the “Configuration” menu you can access “permissions”. This section is one of the most important to preserve the correct functioning of the unit. You can setup users account and grant them the permission to interact with the XWEB 3000. Permissions are a powerful tool to avoid accidental system damage and security holes. XWEB 3000 works with two different levels of permission to allow you to setup a detailed user account privileges system. The first level allow you to grant or forbid the user access to the system menu. The second level allow you to grant or forbid the user access to the sub-menu labels. So, it is possible to grant to 2 different users the same level of access, but forbid to one of them a specific system area. We strongly suggest you to create a user with read only privileges and another one with the ability to change system behaviour. A third user could be the administrator who should be the only one to be able to interact with critical system behaviour, such as alarm setup menu or devices add/delete etc. To create a new user you just have to put the correct name and password, then push on “Add user” button.

To allow a user to interact with the unit, please assign him correct rights. To do this click on “Permission”. You can notice red row menu (master menu) and all its values. You have to check the master value to enable the corresponding access to the menu, then go to the sub-menù and check only those values you need.

Page 87

XWEB 3000 – rel.1.0 –

At the end of the procedure you have to confirm the changes by clicking on “update permissions” button.

3.3.9.1 MANAGING THE USERS

You can interact with a user in 3 different ways:

• Setting-up permission (Permission button)

• Deleting the user (Delete button)

• Logging the user/s (Access log or Access log… button)

Page 88

XWEB 3000 – rel.1.0 –

3.3.10 SYSTEM UPDATE

One of the most important feature of XWEB 3000 is the possibility to update the system via internet (network access or dial-up). Update procedure is divided into 2 main steps. First step makes an internet connection and tries to reach a remote host to begin the download of the new data. Of course the very first action is to compare local XWEB 3000 system release to the one available on the remote host. If every modules are the same on both side, no download starts. On the contrary only the module needed is download. The second step is a completely automatic local procedure that update the software. Pay attention if a power loss occurs the system may fault to re-start. To start the update procedure please go to “Information” roll-down menù and choose “Update”.

This window will appear, of course push “Yes” button to start the procedure.

Please pay attention that if you use a network with a valid gateway, turn off the “dial-up” if it is active. On the contrary if in your network there is no gateway, it means you have no internet access, you have to set-up a proper “dial-up” connection (see “§ 2.2.2 configuration System “). A counter shows you the current module download status, please be patient. At the end of the procedure a message box informing you about the status of the update will appear:

Page 89

XWEB 3000 – rel.1.0 –

To check the system version, please go to “Information” roll-down menù and select modules:

44 SSAAFFEETTYY // AANNDD AALLLLOOWWEEDD UUSSE

Please read carefully what follows. Your security may depends on the respect of these simple rules. We strongly suggest you, to prevent damage to the unit, paying attention to each sentence.

• Remember to protect both yourself and the computer from electrical hazards. The XWEB 3000 should remain turned off until you are finished connecting all electrical devices.

• Before giving the power supply, read the Technical Specification to be sure of the supply voltage you are going to connect.

• The appliance should be connected to a power supply only of the type described in the instruction manual or as marked on the appliance. If you are not sure of the type of power supply to your installation site, consult your appliance dealer or local power company.

• Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, pay particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.

• Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the appliance and to protect it from overheating, and these openings must not be blocked or covered. The appliance should be situated so that its location or position does not interfere with its proper ventilation.

• The appliance may not function properly if used at extremely low, or freezing temperatures. The ideal ambient temperature is above +5°C (41°F).

• The appliance should be situated away from heat sources such as radiators, heat registers etc.

• Care should be taken so that objects do not fall and liquid is not spilled into the enclosure through

openings. If a metal objects, such as a needle, comes into contact with the inside of this appliance, a dangerous electric shock may result.

• Never remove the enclosure. If the internal parts are touched accidentally, a serious electric shock might occur.

• Do not use volatile solvents such as alcohol, paint thinner, gasoline, or benzine, etc. to clean the cabinet. Use a clean dry cloth.

• The user should not attempt to service the appliance beyond that described in the instruction manual. All other servicing should be referred to qualified service personnel.

In this section we describe how you can customize your device regardless its factory setup. We will point out only the main sections, without describing each fields in deep. Please notice that the page is divided in many rows. Each of them customize a particular function of the device itself. To access this section please stop modules, then go to “devices” menu. Here with selection roll-down menù choose the proper device, then with configuration section click on “Advanced” button. First row allows you to apply a polling-cycle of your choice to all devices compatible with the one displayed now. You can do this by setting up all available cycles, then pushing “Set Cycle” button. Be careful that settings are applied to all resources, this means: Analog Resource, Digital Resource and Status/Alarms. The same happens for functions, you can apply global settings by pushing “Set Functions” button. A warning window will appear, if you are sure, please confirm with OK button. “Device name”, “Model” and “name” come from then previous page (you can not modify them here), while “Ypcode”, “YpVerson” and “E2Verison” identify the instrument itself.

Next row is for compatibility reason only, check it if the instrument you are configuring is not a Dixell instrument.

Row “Category” allows you to link the macro category you have defined using “Configuration” rolldown menù to the real topology of the device.

Before proceding pay attention that the options “Used”, ”RunTime” and ”LayOut” mean you want to use that particular value and also want to display it in runtime and layout window. Moreover every section is divided into two separate column: input and output. “Analog Resources” input section shows you all the analog input that a device can use. These values can be displayed in decimal or integer values, of course you have to choose the same unit of measurement for both the XWEB and the instrument. The suffix “-I” means you want to display integer, default value is decimal. The same for Celsius and Fahrenheit degree. The suffix “-F” means Fahrenheit degree.

Warning: the integer/decimal or °C/°F configuration have to be chosen according to the real setting of the instruments.

“Digital Resources” input and output row need particular attention. The values you find here are the factory defaults, so if you have made modifications to the device status, you are requested to apply the same modifications in these menus. This is very important because all the values stored inside

Page 94

XWEB 3000 – rel.1.0 –

XWEB 3000 devices section must be the same as the ones stored inside the EEPROM of the instrument. A common error for example is to modify “Generic Alarm” to some other values inside the instrument, than leave the value marked inside Advanced section. XWEB 3000 will send you an alarm every time the switch changes status, even if it is not an alarm input.

“Status/Alarms” section allows you to customize your instruments, of course the same values have to be set both on XWEB 3000 and the instruments themselves.

“Commands” row is very important. You have to mark same values that you have marked before in the other section. In order to give Xweb 3000 the possibility to send commands to the instruments. This is necessary because for example if you have changed “Generic Alarm” to “Ausiliary” in “digital Resources” section, then you have to mark “Aux on” and “Aux off” in “Commands” section to be able to turn on/off the output by means of the Xweb 3000. Of course you have to do this kind of changes every time you have made some modifications to the instruments.

Last row “Functions” allows you to link the macro-category previously set, to the particular instrument

CSMA/CD - Carrier Sense Multiple Access Collision Detection is a network access method in which devices that are ready to transmit data first check the channel for a carrier. If no carrier is sensed, a device can transmit. If two devices transmit at once, a collision occurs and each computer backs off and waits a random amount of time before attempting to retransmit. This is the access method used by Ethernet. Coaxial Cable - Cable consisting of a single copper conductor in the center surrounded by a plastic layer for insulation and a braided metal outer shield. Concentrator - A device that provides a central connection point for cables from workstations, servers, and peripherals. Most concentrators contain the ability to amplify the electrical signal they receive.

Fast Ethernet - A new Ethernet standard that supports 100 Mbps using category 5 twisted pair or fiber

optic cable. Fiber Optic Cable - A cable, consisting of a center glass core surrounded by layers of plastic, that transmits data using light rather than electricity. It has the ability to carry more information over much longer distances. File Server - A computer connected to the network that contains primary files/applications and shares them as requested with the other computers on the network. If the file server is dedicated for that purpose only, it is connected to a client/server network. An example of a client/server network is Novell Netware. All the computers connected to a peer-to-peer network are capable of being the file server. Two examples of peer-to-peer networks are LANtastic and Windows for Workgroups.

Gigabit Ethernet - An Ethernet protocol that raises the transmission rates to 1 Gbps (gigabits per

second). It is primarily used for a high speed backbone of a network.

Hub - A hardware device that contains multiple independent but connected modules of network and

internetwork equipment. Hubs can be active (where they repeat signals sent through them) or passive (where they do not repeat but merely split signals sent through them).

Infrared - Electromagnetic waves whose frequency range is above that of microwaves, but below that

of the visible spectrum.

Intranet - Network internal to an organization that uses Internet protocols. Internet - A global network of networks used to exchange information using the TCP/IP protocol. It

allows for electronic mail and the accessing ad retrieval of information from remote sources.

ISP (Internet Service Provider) - Company that provide access to internet

LAN (Local Area Network) - A network connecting computers in a relatively small area such as a

building.

Linear Bus - A network topology in which each node attaches directly to a common cable. LocalTalk - Apple Corporation proprietary protocol that uses CSMA/CA media access scheme and
