Tankvision Multi Scan NXA83B Overview

3.2 Configurator

The Multi Scan NXA83B is configured using the Tankvision Multi Scan Configurator software.

The software is pre-installed on the D drive of the NXA83B and may be accessed using remote control from a networked PC.

The Multi Scan NXA83B actually has two copies of its database:

• The Runtime database stored in the ProgramData folder on the D drive. This is the database that is actually used as the current "live" database and is never directly edited by the user.

• The Configurator copy of the database stored in the Configurator folder on the D drive.

This is the one that is edited by the user when using the Configurator software.

The procedure to edit the Multi Scan NXA83B database is to use the Configurator software in the Multi Scan NXA83B to edit the configurator database. Then when the changes are complete the new database must be set as the Runtime database using the Set As Runtime

Database menu option. The database will be automatically copied to the ProgramData folder and the DCC services restarted.

From version 3.1.0 / 4.0.0 onwards there is no need to carry out a commit or reboot the Multi Scan NXA83B. The new database will immediately become active after the

DCC services have restarted.

Multi Scan NXA83B configuration consists of the following sets of tasks:

• Configuring the operating system functions such as Networking, Printers etc.

• Configuring the Features to be used, such as Alarm Annunciation , TouchScreen display etc.

• Configuring the database

The first set of tasks can be carried out either directly on the Multi Scan NXA83B using a keyboard/mouse or via a remote networked PC. These tasks will be described in this section.

The second set of tasks (configuring the database) can only be carried out via a remote networked PC, using the Tankvision Multi Scan Configurator set of tools already loaded onto the NXA83B. This constitutes the bulk of the configuration work for the Multi Scan NXA83B and is covered in a separate Configuration manual. An introduction to the Configurator tools will be given in this section.

It is no longer necessary to carry out a commit when modifying the tankgauging database. However, when certain system features are modified then they will not be permanent until committed in the Enhanced Write Filter. These will be defined later in this document.

5.1 Using Remote Desktop Connection on a networked PC

In many circumstances it is not feasible to connect a Keyboard and Mouse directly to the

Multi Scan NXA83B, but access to the operating system is required. In this case a networked

PC can be used to take control of the Multi Scan NXA83B using the Windows feature called

Remote Desktop Connection.

The Multi Scan NXA83B and remote PC must be networked together, either as part of a larger network, or directly using a network cable.

To connect using a direct connection:

Set the networking on the remote PC to a Fixed IP address with a value similar to the

Multi Scan NXA83B. For instance if the Multi Scan NXA83B address is 192.168.1.250, set the PC address to 192.168.1.251.

Connect a cross-over network cable between the Multi Scan NXA83B and the PC. For more details, refer to the Installation manual (BA01290G).

On a PC running Windows XP select Start  All Programs  Accessories  Desktop

Connection .

Or, on a PC running Windows 7 run C:\Windows\System32\mstsc.exe

Enter the computer name (or IP adress) of the Multi Scan NXA83B into the Computer field (e.g. 192.168.1.250

Endress+Hauser

Click OK .

The display on the Multi Scan NXA83B will now be shown on the remote PC. For details

on how to stop the operator display to gain access to the operating system  ä 12.

When the remote session is established, the screen on the Multi Scan NXA83B will no longer be active and will display the standard Windows login message. Therefore only use the Remote System Login when it is safe to. I.e. when no operator needs to view data on the

Multi Scan NXA83B.

5.2 Accessing the Multi Scan NXA83B operating system

The Windows XPe operating system is normally hidden behind the main Multi Scan

NXA83B operator screens, and cannot be accessed. However, in order to carry out most configuration tasks, access is required to the operating system. In this case the operator display must be stopped.

To do this first requires keyboard/mouse input, which can be carried out in one of two ways:

• Connect a PC to the Multi Scan NXA83B using the Ethernet port and take control of the

Multi Scan NXA83B using the Windows Remote Desktop Connection (recommended).

• Connect a keyboard and mouse to the USB ports of Multi Scan NXA83B and use the LCD display.

For details on the latter method  ä 11.

To stop the operator display screens, open the right ( Screens ) menu, select the down arrow to show the next bank of options and click on the Exit option.

NOTICE

Any changes of the windows settings could affect the correct operation of the Multi

Scan NXA83B. Therefore:

‣

Take extreme care when modifying any of the windows settings.

5.2.1

Exiting from the Remote Desktop session

If no changes have been made to the configuration and the remote desktop session is no longer required, then the NXA83B can be returned to the standard Operator Touchscreen using the Return To Main Screen shortcut.

NXA83_Windows-Desktop_Return-to-Main-Screen_Icons

This will automatically close the remote session and restart the operator display on the touchscreen.

If any changes have been made to the operating system settings then a Commit should be carried out instead of this option. If the tankgauging database only has been modified then a commit is not required.

Endress+Hauser

Tankvision Multi Scan NXA83B Connecting, Network Settings, Windows XPe

5.3 Network Settings

For the physical locations of the network connections, refer to the Installation manual

(BA01290G).

The Multi Scan NXA83B is shipped with the following default network settings:

• Computer Name: NXA83B

• Fixed TCP/IP Address: 192.168.1.250

For most applications these will be perfectly adequate and should be left as standard.

However they may be changed at configuration time to fit in with an existing network on site.

To change the settings follow the procedure described in this manual (  ä 15).

The TCP/IP address can be changed using the Local Area Connection properties in the

Control Panel. This includes using DHCP to dynamically assign an address on an established network.

Any changes affecting the operating system will not be permanent until committed in

the Enhanced Write Filter (  ä 17).

5.4 Renaming the NXA83B network name

The Multi Scan NXA83B runs under the Windows XP operating system, therefore the computer name may be modified in the same way as any normal PC.

The network name of the Multi Scan NXA83B is set by default to "Multi", and in most cases it is recommended that it be left as this.

However, if the name needs to be changed then this can be performed using the following procedure:

Start a remote session (refer to Remote System Login section).

Open the System Properties option from the Control Panel of the remote Multi Scan

NXA83B.

Change the Computer Name as normal. Do NOT reboot the Multi Scan NXA83B at this stage.

Select the option from the windows start menu;

Start  Programs  Tankvision Multi Scan Configurator  Rename SQl Instance

This will run a batch file that requires the old name to be entered, followed by the new name.

After this, select Start  Programs  Commit  Commit from the windows start menu to make the changes permanent.

Create a new project in the Tankvision Multi Scan Configurator software with the new network name.

Upload configuration from the Multi Scan NXA83B.

NOTICE

Modifying the NXA83B name will have repercussions in the Tankvision Multi Scan

Configurator tool as it uses that name to communicate with the Multi Scan NXA83B.

Therefore:

‣

After changing the NXA83B name, edit the project settings and update the System

Name.

Endress+Hauser 15

Connecting, Network Settings, Windows XPe Tankvision Multi Scan NXA83B

5.5 Changing the Multi Scan NXA83B Network Address

The Multi Scan NXA83B runs under the Windows XP operating system, therefore the network address and mode may be modified in the same way as any normal PC.

The network protocol is set to TCP/IP, but the address may be set as required. This includes using DHCP to dynamically assign an address on an established network.

The network settings will be set by default to: FIXED address of 192.168.1.250.

The network settings may be changed by the carrying out the following:

Start a remote session (refer to Remote System Login section).

Open the Network Connections option from the Control Panel of the remote Multi Scan

NXA83B.

Modify the settings as normal.

After this, double click the Commit shortcut to make the changes permanent.

The remote session will be disconnected.

5.6 Printer Settings

In order for the print features in the Multi Scan NXA83B to work, a printer needs to be configured in the Windows XPe operating system as the DEFAULT printer.

A printer can be installed after the Multi Scan NXA83B has been shipped, in the same way as installing on a normal PC running Windows XP. However, due to the restrictions on the flash disk space, it is recommended that only the basic printer driver should be loaded and not any print utilities. After installing a new printer, remember to delete ALL other printers from the system.

For the above reasons it is recommended that Endress+Hauser should be consulted on the type of printer to be attached to the Multi Scan NXA83B.

The printer should normally be connected to the Multi Scan NXA83B via one of the USB ports. However network printers can also be supported.

Any printer setting changes will not be permanent until committed in the Enhanced

Write Filter.

Only ONE printer is supported, therefore delete ALL other printers installed on the system.

5.7 Connecting a modem

The communications layer of the Multi Scan NXA83B, DCC, can handle modem communications on both master and slave interfaces.

At the moment an external modem should be used, connected to one of the serial ports.

However it should also be possible to connect via the USB ports.

The modem driver should be installed on the operating system as for a normal PC running

Windows XP.

It is recommended that Endress+Hauser should be consulted before selecting the modem, or

Endress+Hauser can supply a suitable modem.

Any modem setting changes will not be permanent until committed in the Enhanced

Write Filter.

Tankvision Multi Scan NXA83B Connecting, Network Settings, Windows XPe

5.8 Enhanced Write Filter (EWF)

The Multi Scan NXA83B runs under the Windows XP Embedded (XPe) (WES2009 from v4.0.0 onwards) operating system, which includes a component called the Enhanced Write

Filter (EWF).

This is used to protect the C drive which contains the operating system. It prevents files from being corrupted by a sudden loss of power; therefore it is perfectly safe to switch off the

Multi Scan NXA83B without shutting down the operating system.

It works by caching all disk and operating system changes. The cache is only permanently written to the flash disk when an EWF COMMIT action is called. This action saves the data to the flashdisk then reboots the Multi Scan NXA83B, thus making the modifications permanent. If the Multi Scan NXA83B is rebooted without a commit, or loses power, then all changes are lost.

NOTICE

Risk of malfunction!

‣

Never disable the enhanced write filter!

The C drive is part of the EWF protection, therefore any data written to that drive (including any changes to the Windows operating system) requires a commit to save permanently.

The D drive is not part of the EWF protection, therefore any data written to that drive is immediately permanent and does NOT require a commit to save. The Multi Scan NXA83B tangauging database is stored on the D drive and does not require a commit to make changes permanent.

For users familiar with versions prior to 3.1.0, the COMMIT shortcut has been removed from the desktop and is now located as an item in the Windows menus.

To commit changes to the C drive, carry out the following:

Close all currently open programs.

Click on the Windows start menu item Start  All Programs  Commit  Commit .

Endress+Hauser

A DOS shell wil be displayed as shown below.

NXA83_Windows-Desktop_Commit_Start-menu

Connecting, Network Settings, Windows XPe Tankvision Multi Scan NXA83B

NXA83_Windows-Desktop_Commit_EWF-Window

Press any key to continue.

The system will now shutdown and start saving all data permanently to the flash drive.

The remote desktop session should be closed automatically.

Eventually the screen goes blank. This is the state when the new data is being written to the C drive. This may take upto a few minutes depending on the amount of changes that have occurred.

NOTICE

Risk of operating system corruption!

‣

Never switch off the power during this period!

Eventually the system will reset and start booting as normal, denoted by a “beep” noise coming from the Multi Scan NXA83B. All data has now been saved.

From the time that the commit is started (step 3) until the system reboots (step 6) the system should be left alone with no user interaction, and never switch off the power.

There are very rare instances where the system does not reboot after the commit, but stays in the blank screen state (step 5). In this case, leave the system for at least 15 minutes before switching the power off and back on, and allow the system to reboot. Check if the changes have been saved.

The Multi Scan NXA83B can be setup to suit a number of applications where certain features may not be required. For instance on large refineries the Alarm Annunciation pop-up screen may not be required, or simple data gatherer systems may not require volume calculations.

The Features that may be configured include the following:

• No Annunciation of Events – the event viewer will not be started, but events will still be logged to the standard event log files so they can be viewed historically.

• No Operator Touchscreen display – the operator screens will not be started. This option may be of use if the Multi Scan NXA83B has no touch screen installed.

• No Programmable Alarms – the programmable alarm configuration screens will not be available in the Configurator.

• No Volume Calculations – the screens associated with volume calculations will not be available in the Configurator. These include the Tank Characteristics , Tank Capacity

Tables and Product Configuration screens.

To configure the Features, click on the Windows start menu item Start  All Programs 

Commit  Set Features and Commit .

NXA83_Configuration_025

This screen will ask a series of Yes or No questions to enable or disable the features. After all have been answered by entering a 'Y' or 'N', it will then carry out a Commit and reboot to make the changes permanent.

5.10 Configuring the Multi Scan NXA83B database

The Multi Scan Configurator software is used to configure the database for the Multi Scan

NXA83B.

The Configurator software may also be installed on a separate PC if required, although it is recommended that the onboard tools are used.

The Multi Scan NXA83B actually has two copies of its database:

• The Runtime database stored in the ProgramData folder on the D drive. This is the database that is actually used as the current "live" database and is never directly edited by the user.

• The Configurator copy of the database stored in the Configurator folder on the D drive.

This is the one that is edited by the user when using the Configurator software.

The procedure to edit the Multi Scan NXA83B database is to use the Configurator software in the Multi Scan NXA83B to edit the configurator database, then when the changes are complete the new database must be set as the Runtime database using the Set As Runtime

Database menu option. The database will be automatically copied to the ProgramData folder and the DCC services restarted.

From version 3.1.0/4.0.0 onwards there is no need to carry out a commit or reboot the

Multi Scan NXA83B. The new database will immediately become active after the DCC services have restarted

To run the Configurator software on the NXA83B, a suitable PC should be connected to the

Multi Scan NXA83B via a standard Ethernet network. This could be as part of a larger network or using a direct cross-over network cable between the PC and the Multi Scan

NXA83B.

Before running the software, the user should log onto the NXA83B using the Windows

Remote Desktop Connection and shut down the tankgauging display, so that access to the

NXA83B operating system is available. For details on how to do this,

 ä 12.

To start the Configurator tools, double click on the Tankvision Multi Scan Configurator icon on the NXA83B desktop.

NXA83_Windows-Desktop_Return-to-Main-Screen_Icons

The Configurator software allows the Multi Scan NXA83B to be configured for a wide range of functions, including:

• Host and Slave Communication ports

• Tank Inventory Data

• Programmable alarms

• Products

• Manual data

• Strapping data

The standard tank gauging displays for the Multi Scan NXA83B may also be configured to display only the data required.

When configuration is complete the database may be set as the Runtime by clicking on the menu option Set As Runtime Database . The database will be automatically copied to the

ProgramData folder and the DCC services restarted. There is no need to carry out a commit.

5.14 Multi Scan NXA83B Watchdog

The Multi Scan NXA83B has a system watchdog component that monitors the health of the

DCCHost communication service. If no communications occur (i.e. gauge data is not updated) for one minute, then the Multi Scan NXA83B will automatically reboot.

The watchdog will always be set to enabled when a Multi Scan NXA83B is dispatched from

Endress+Hauser. It should always be enabled during normal operation.

There should be no need to manually disable the watchdog, as this will be done automatically when required, for instance when the DCCServices are stopped or a Firmware update is carried out.

5.15 Diagnostic Logging

The Multi Scan NXA83B maintains a set of log files to record such items as alarm/events, system startup, system changes etc. These are logged in the "Historical" directory on the D drive. This directory is also shared on the network and can be accessed remotely for diagnostic purposes.

All files in the Historical directory are text files and can be read using the standard Notepad program. The File "ActionsRecord.log" records actions which can change the functioning of the Tankvision Multi Scan and other items such as boot times, watchdog trips etc.

NXA83_Configuration_029

The directory "Events" is used to store the historical event log files, with a separate file being created per day.

Tankvision Multi Scan NXA83B Database Configuration

7 Database Configuration

7.1 Port Configuration

The Multi Scan NXA83B has a component installed called the Data Communications

Controller (DCC) which consists of a number of services responsible for transmitting tank data to and from the device.

The three main services are:

• DCC Host - responsible for retrieving data from gauges and storing it in the database

• DCC Slave - responsible for sending tank data to other computer systems

• OPC Server - responsible for providing tank data to OPC clients

The Host and Slave services control communications over a number serial ports on the Multi

Scan NXA83B and these must be configured with a software protocol before they can be used.

The OPC Server service communicates via the network and requires no configuration.

This section of the manual provides an overview of how to configure the NXA83B communications sub-system. For a more detailed description refer to the separate DCC

Configuration manual (BA01292G).

7.1.1

Data Communications Controller

The ports used in the DCC component of the Multi Scan NXA83B are configured by selecting the Port Configuration option from the Communications menu of the Tankvision Multi

Scan Configurator.

This consists of a number of tabbed pages to configure the Host and Slave ports.

Configuring a Host or Slave port

Host ports are responsible for collecting data from Datacons and gauges, and command requests from any PC Tankgauging clients.

Slave ports are responsible for sending data to other computer systems, such as the main

Distributed Control System (DCS) for the refinery, using protocol such as Modbus.

To configure a port click on the Host Comms or Slave Comms tab in the Data

Communications Controller tool.

Tankvision Multi Scan NXA83B Database Configuration

7.3 Gauge Configuration

The Multi Scan NXA83B must be configured for all gauges which will be used in the database.

This consists of defining data for each gauge, such as name, type, COM port etc., and is carried out using the Gauge Configuration tool.

To launch the Gauge Configuration tool, select Gauge Configuration from the

Communications menu. The Gauge Configuration will hold any gauges/field devices that are already configured, for review or editing of their settings. Alternatively, the form will be empty if no gauges/field devices have been configured yet.

Each manufacturers gauge has different basic requirements for configuration. A knowledge of the different makes and models of gauges is useful at this stage although not essential, provided that the characteristics of the actual gauges present in the system are known. The following instructions do not provide an exhaustive guide as to the valid options and selections for each type of gauge; rather instruction is given as to the way in which the information is entered into the system.

A set of Application notes are available which give more detailed information on how to configure the different gauge types. In addition to this manufacturer’s literature should be consulted for further information.

Endress+Hauser

NXA83_Configuration_001

The form displays the configuration of one device (such as a gauge) at a time. The buttons on the lower left of the form navigate through the list of gauges. The < and > buttons move one gauge back or forward respectively. The |<< button moves to the first gauge and the

>>| button moves to the last. The Device Number drop-down list provides an alternative means of navigating directly to a particular gauge. The Device Numbers are allocated automatically by the system as new gauges are added, generally in order of creation, and cannot be edited by the user.

To add a new device to the list, click on the Add button. A new blank entry will be displayed and the editing features will be enabled. Alternatively, a new gauge may be added to the list by copying an existing one. In this case, click on the Copy button and then select the gauge from which the copy should be made. This will produce a new entry and the editing features will be enabled, but the displayed settings will replicate those of the gauge from which the

Database Configuration Tankvision Multi Scan NXA83B copy was made. The effect of adding a gauge to the configuration will usually be to add a corresponding tank to the Multi Scan NXA83B display, unless the gauge is part of a multigauge setup.

To delete an existing device, click on the Delete button. Doing so will remove the corresponding tank from the Multi Scan NXA83B display unless the device is part of a multigauge setup.

To edit the configuration of an existing device, navigate through the list to the desired device and then click on the Edit button.

The buttons at the right side of the form will be enabled (black text) or disabled (greyed out) depending upon the context of what stage in the configuration the user is at. For example, the Save button will be enabled whenever any setting for the currently displayed device is changed, prompting the user to apply any changes before moving on to another device. A message box will be displayed as a further reminder to apply changes.

Closing the tool by means of the Exit or × button or selecting a different device without saving first will discard any changes made. To discard any erroneous changes made whilst editing the configuration of a device, click on the Cancel button.

When configuring a new device, it is recommended to progress through the selections and options in column order, starting by working down the left column. Certain selections, e.g.

Device Type , will affect the appearance and data entry requirements of other settings and options further down the column and may "clear" any current settings in preparation for the user's new entries.

Once all settings for the gauge have been configured, apply the settings by clicking on the

Save button

Once all configurations have been completed, click on Exit to leave the Gauge Configuration tool.

Common fields

The following fields will be displayed for most device types.

The Device Type drop-down list provides a selection of gauges and field devices of various models from various manufacturers. Select the one that matches or most closely resembles the actual gauge or device which will be connected. Note that the selection affects the way in which the communications of the Multi Scan NXA83B behaves.

The Tank Id entry links the gauge to a tank in the Multi Scan NXA83B system. Typically, each gauge will be associated with a unique tank, though in the case of multi-gauge setups there will be a number of gauges all fitted to the same tank and thus share a common Tank

ID.

Comm Port is the number of the port on the Multi Scan NXA83B to which the the gauge itself is connected. There are two fields for the Comm Port. The left hand field is the main

COM port used for communications, and should always have a value entered. In Advanced mode a right hand field will also be displayed but is only required for redundant systems, and specifies the Backup Comm Port .

If the gauge is one of a number of gauges all fitted to the same tank, select Multi-Gauges .

An additional frame will be displayed wherein the Gauge Duty should be selected. There should be only one Primary Gauge on each tank, the others should be Secondary Gauges or

used for other specific duties as listed in the drop down menu (  ä 41).

Certain gauges which are provided with multi-element averaging or multi-spot temperature measurement may allow the individual element temperatures to be read via the communications. If this feature is available and desired, select Poll For Temp. Elements .

Database Configuration Tankvision Multi Scan NXA83B

The average product temperature will normally be polled for regardless of this setting, therefore only tick this box if the individual elements are required to be available in the

Multi Scan NXA83B.

Certain gauges which are provided with skin temperature measurement may allow the individual temperatures to be read via the communications, up to a maximum of

250 elements. This feature is normally only available on LNG tanks and is used in combination with an auxiliary gauge. If it is available and desired, select Skin Temp. Fitted .

7.3.3

Gauge specific fields

The fields displayed in the area outlined below will vary depending on the device type selected.

NXA83_Device-Configuration_Gauge-Specific-Fields

Gauge specific fields

The fields in this area generally refer to device/gauge addresses, Modbus registers, communication tasks etc., and are very specific to the Device being configured and the protocol being used to communicate.

Refer to the separate Application notes for full descriptions of what fields are available for a device type and how to configure them.

7.3.4

Background Scan fields

Product Level is the primary data item and is the default item polled from the gauge by the system. Background scan settings are used to read Auxiliary data parameters other than

Product Level from the gauge at lesser frequency than the Level polls.

The fields displayed in the Background Scan section are dependant on the Device Type selected and generally are used to enable polling for parameters such as Temperatures,

Pressures, Density, Water Level etc.

7.3.5

Advanced fields

The following fields are normally only displayed if the Advanced view is selected.

TankMaster Index /Datacon Gauge Index

This field is not normally required for a Multi Scan NXA83B and should normally be left as zero. However there are a number of circumstances where it may be required, as outlined below.

If a TankMaster slave interface has been configured the TankMaster Index will be the index used to reply to requests from a Tankmaster system. Each Device should have a separate unique index, from 0 to 255.

If a Datacon master interface has been configured, and the Comm Port for this device has been assigned to that interface then the Datacon Gauge Index is the address, or "position" within the internal configuration database, of the Datacon where this gauge will reside. The positions are addressed from 0 to 255. Each gauge must have a unique Tank Address, which for convenience should normally be set the same as the Gauge Number.

This field is NOT required if only Datacon slave interfaces have been configured on the

Multi Scan NXA83B.

Flow Rate Damping and Flow Rate Integration

To alter the response of the level flow rate measurement by the system, and consequently the volume and mass/weight flow rates, two parameters are available for user configuration.

The Flow Rate Damping factor is a percentage measure of how much of the current instantaneous flow rate reading is incorporated into the filtered value. Increasing the figure increases the responsiveness of the resulting flow rates but reduces the effective damping.

The Flow Rate Integration factor is a time in seconds, up to 240 seconds maximum (four minutes), used to increase the effect of damping where the level readings/flow rate calculations are performed at shorter intervals depending upon the number of gauges present on the particular communications port.

7.3.6

Change Dimensions

The Multi Scan NXA83B will assume that any values read from the gauges/field devices are in Metric units unless the system is able to determine the measurement units of the gauge/ field device automatically via the communications. If this is the case, the Change Dimensions entries should be left in their default setting of AUTO . With certain gauges, the system must be configured specifically to match the measurement units of the data from the gauge by selecting the appropriate units of measure from the drop-down lists.

7.3.7

Multi Gauges

Tanks may be fitted with more than one gauge, for enhanced reliability. For example most

LNG tanks will typically have two level gauges, one alarm gauge and one densitometer device fitted. To configure multiple gauges for a tank, perform the following in the Gauge

Configuration screen:

Enter the same Tank Id for each gauge.

Tick the Multi Gauges box, this will display the Gauge Duty panel.

Select the appropriate duty from the Gauge Duty panel.

Drop Down Menu: Tank ID

Tickbox: Multi Gauges

Drop Down Menu: Gauge Duty

Most configuration data entered for the multi-gauge tanks will be saved for all the gauges on that tank. This applies to data entered in the Tank Characteristics and the Alarm

Configuration screens. Consequently, when a programmable alarm is triggered on a multigauge tank, an alarm event will be generated for each gauge on the tank.

Data entered in the Manual Data screen only applies to an individual gauge.

The Gauge Duty defines how the gauge will be treated in the various operator displays. Most of the default screens supplied with the NXA83B are configured to display the primary gauge data. However they may be configured to show data from any other duty.

The available gauge duties are listed below.

Primary

One gauge must be configured as the primary duty gauge. This is the normal gauge used to display tank data in the operator screens.

If a Densitometer duty gauge is also present on a tank then the Product Density and

Observed Temperature will be automatically be copied from the Densitometer to the primary.

Only one Primary gauge may be configured per tank.

Secondary

If a second level gauge is required on a tank, e.g. for redundancy purposes, set the duty of this gauge to Secondary. The secondary gauge may be added to the displays as required and may be accessed via Modbus and OPC interfaces. If the Difference Alarm is enabled for a tank, it monitors the Primary and Secondary gauge levels and generates an alarm if they differ by more than the preset tolerance.

Only one Secondary gauge should be configured per tank.

Backup

Any furher level gauges on a tank should be configured as Backup duty. These may be added to the displays as required and may be accessed via Modbus and OPC interfaces. The alarm gauge in an LNG tank should be configured as Backup duty.

Endress+Hauser

Tankvision Multi Scan NXA83B Database Configuration

Densitometer

This duty is only required for LNG tanks. Densitometer is used for devices such as the

Scientific Instruments 6280/6290, although any gauge capable of carrying out profiles may be configured as a densitometer. The main purpose of Densitometer gauges is to carry out profiles and calculate the product density, which is then automatically transferred to the primary gauge for volume calculations.

Auxiliary

An auxiliary gauge is different from all other gauge duties. It is not treated as a separate gauge, instead it is used to retrieve background scan parameters (pressures, temperatures, water bottom etc.) from a separate device and store them in the Primary gauge.

An auxiliary gauge will not poll for level, generate alarms or be displayed in the operator screens. It is typically used on a Modbus TG interface to access parameters from devices such as pressure transducers. All data retrieved from an auxiliary gauge will be transferred to the

Primary gauge and used in the volume calculations.

Parameters that may be polled on an auxiliary gauge include:

• Product Temperature

• Vapour Temperature

• Density

• All Pressures

• Multi-Element temperatures (not transferred to Primary)

• Skin Temperatures (not transferred to Primary)

• Water bottom

7.4 Tank Characteristics

Tank Characteristics allows entry of or editing of the main tank operating parameters.

A number of the data items are important to the tank inventory calculations and it is therefore essential that they are configured correctly.

The tank characteristics module is a multi-tabbed data entry form where data has been organized into logical groups.

Tank characteristics are divided into several sections:

• Tank Details

• Tank Capacity Tables

• Roof Details

• Shell Correction

• Miscellaneous

• VCF Settings

• Calculation Control Settings

• Input Control Settings

Some values are dependent on other settings. Indeed some fields are not visible or enabled until they are called for by the setting of another parameter.

The use of this feature can be controlled by the security system.

Some settings are specific to certain calculation methods.

Roof Details

The Roof Details section contains data that is relevant to floating roof tanks, i.e. those that have been defined with a tank shape of VCFR.

NXA83_Tank-Characteristics_Roof-Details

Leg Position

Some floating roofs have legs which may be set at two positions, thus altering the level at which the roof floats or is supported on the legs. Since the legs are usually attached to the floating roof, the Up position of the legs allows the roof to descend to a lower level in the tank, and is the setting used in normal operation, whereas the Down position causes the roof to become supported on its legs at a higher level and is the setting used for maintenance purposes.

Where a tank has a floating roof with fixed or one - position legs, it is advisable to set the

"Legs Up" and "Legs Down" levels to be the same so that the Legs "Up/Down" selection becomes irrelevant.

Fully Floating Level, Legs Up – The point at which the roof just ceases to be resting on its legs when the legs are in the "up" or operational position, such that the whole weight of the roof is being supported by its buoyancy in the product. Above this level, compensation is made for the displacement of the product by the full weight of the roof.

Fully Floating Level, Legs Down – The point at which the roof just ceases to be resting on its legs when the legs are in the "down" or maintenance position, such that the whole weight of the roof is being supported by its buoyancy in the product. Above this level, compensation is made for the displacement of the product by the full weight of the roof.

Endress+Hauser

Tankvision Multi Scan NXA83B Database Configuration

Fully Supported Level, Legs Up – The point at which the roof legs are supporting the full weight of the roof when the legs are in the "up" or operational position. Below this level, no compensation is made for product displacement caused by roof weight.

Fully Supported Level, Legs Down – The point at which the roof legs are supporting the full weight of the roof when the legs are in the "down" or maintenance position. Below this level, no compensation is made for product displacement caused by roof weight.

The area between the Fully Supported and Fully Floating levels is generally referred to as the roof transition zone. Between these levels it is difficult to determine the proportion of the roof's weight which is being held by the legs and therefore difficult to calculate the displacement of product by the roof. For this reason this region of the tank is normally avoided during normal operation.

Tank Corrections

Endress+Hauser

NXA83_Tank-Characteristics_Shell-Correction

The tank correction information is only relevant if you have enabled shell correction on the

Inventory Control Settings tab.

Shell Insulation Factor – 1 for completely insulated storage, 0 for un-insulated storage,

0.875 is a typical value.

Shell Expansion Coefficient – Expansion coefficient of the material your tank is constructed of, e.g. 0.0000112 for mild steel.

Database Configuration Tankvision Multi Scan NXA83B

Shell Reference Temperature – Normally the same reference temperature used for your

VCF calculations (normally either 15 °C or 30 °C).

Manual Air Temperature – The manual air temperature setting, if your gauge can provide an automatic air temperature, then leave it unchecked.

Gauge Temperature Coefficient – The linear coefficient of thermal expansion for the gauge and it's mountings. The typical values are the same as those for Shell Expansion Coefficient.

Gauge Reference Temperature – The temperature at which the gauge was calibrated.

Float Diameter – Diameter of the gauge float.

Float Weight – Weight of the gauge float.

Float Reference Density – The density of the fluid in which the float was calibrated.

Integration. These are entered in the Gauge Configuration screens.

NXA83_Configuration_017

Theft Alarm

This option is currently not supported.

Database Configuration Tankvision Multi Scan NXA83B

Unauthorised Movement Alarm

This alarm is often referred to as a Leak Alarm although it applies equally to a gain or a loss of product. The Multi Scan NXA83B refers to these as unauthorised movements.

NXA83_Alarm-Configuration_Unauthorised-Movement-Alarm

The unauthorised movement alarm is intended to protect against inadvertent movement of product in static tanks. The "Unauthorised Movement by Volume/Level" or Leak Alarm can be enabled on systems where the Movements sub-system is not in use. This alarm should be enabled when the tank is to remain static, this has the action of internally storing the current

GSV for the tank, should the GSV in the tank change beyond the predefined threshold limit, then the alarm will be triggered. The alarm should be disabled when movement of product into or out of the tank is being done.

Threshold – An operator configurable threshold to determine when an Unauthorised

Movement alarm should be raised.

Flow Alarms

The flow alarms are intended for use when tanks are moving. They are useful to detect that flow has exceeded a tank or pipeline design limit or that flow has reduced or stopped perhaps due to some fault.

There are upper and lower zone alarms for filling and emptying the tank. The flow thresholds for each zone can be set for a rising or falling level.

Endress+Hauser

Tankvision Multi Scan NXA83B Database Configuration

Endress+Hauser

NXA83_Alarm-Configuration_Flow-Alarms

By manipulating the zones it is possible to have just one set of alarms.

• Falling – The change from upper to lower zone when emptying a tank

• Rising - The change from lower to upper zone when filling a tank

• Upper zone flow rates – max and min flow rates for the upper zone

• Lower zone flow rates - max and min flow rates for the lower zone

Upper and Lower zone flow rates are set for both a rising and a falling level.

Gauge Alarms

Gauge alarms are those alarms that are generated by the gauging instrument itself. The alarm levels displayed here are normally only there for reference purposes.

On some modern technology gauges it is possible to read the gauge alarm settings from the gauge automatically. On older gauges this is not possible however for these devices provision is made to enter these manually through this module.

Detection of gauge alarms is performed by the gauging instrument and not by the tank gauging software. The system merely reads the status of the alarm bits transmitted to it by the gauge.

Gauge alarm settings are normally set by the gauge commissioning engineer.

• Gauge Alarm High High : The gauge high high level alarm setting

• Gauge Alarm High : The gauge high level alarm setting

• Gauge Alarm Low : The gauge low level alarm setting

• Gauge Alarm Low Low : The gauge low low level alarm setting

Programmable Variable Alarm

The Programmable Variable Alarm is used to trigger an alarm when the level gets above or below a set point, dependent upon the direction of flow.

The programmable variable alarm is an additional level alarm provided for use on moving tanks, it incorporates a configurable "advanced warning" alarm to indicate that product level is nearing the alarm level set point.

Database Configuration Tankvision Multi Scan NXA83B

NXA83_Alarm-Configuration_Programmable-Variable-Alarm

The user configurable fields are:

• Enabled – Tick the box to enable the alarms.

• Level – The point at which the level alarm is triggered.

• Hysteresis – Amount by which Level must fall/rise (dependent upon flow direction) to cancel alarm.

• Time To Target – Amount of advanced warning before level alarm point will be reached.

The remaining time is calculated from the flow rate and an alarm will be raised at the specified time.

• Time To Target Hysteresis – A hysteresis value to compensate for fluctuations in flow rate.

• Direction – Alarms are dependent upon flow direction. Set the arrow to indicate the direction of flow; Up for Receipts (tank filling) and Down for Loading (tank emptying).

Double click on the arrow to toggle direction.

• No Flow Volume – An alarm is raised if the Volume flow rate falls below the value entered here.

• No Flow Cons. Time – The "Consideration" time for the No Flow Volume alarm. When a movement starts no alarm will be raised for the period specified to allow the flow rate to stabilize.

Endress+Hauser

Tankvision Multi Scan NXA83B Database Configuration

Programmable Level Alarms

Programmable level alarms are triggered according to the gauged level, they can be used on gauges where hardware alarms are not available or used in addition to the gauge hardware alarms.

Endress+Hauser

NXA83_Alarm-Configuration_Programmable-Level-Alarms

• Enabled – An operator configurable level alarm enable flag.

• High High – An operator configurable level alarm denoted High High.

• High – An operator configurable level alarm denoted High.

• Low – An operator configurable level alarm denoted Low.

• Low Low – An operator configurable level alarm denoted Low Low.

• Hysteresis – An operator configurable hysteresis value.

The term High High is normally associated with the extreme upper limit to which a tank would be filled. Under normal operating conditions it would be unusual to trigger this alarm.

Consequently the term High is not as extreme as High High and is normally set a small distance below the High High limit.

The term Low Low is normally associated with the extreme lower limit to which a tank would be emptied. Under normal operating conditions it would be unusual to trigger this alarm.

Consequently the term Low is not as extreme as Low Low and is normally set a small distance above the Low Low limit.

Clearly it is essential that all the alarms being used are configured correctly.

The programmable level alarms have equivalent gauge alarms. The programmable alarms would normally be set slightly below and slightly above their respective gauge alarm values.

The programmable alarms would normally be used as early warnings to the gauge alarms.

However the user can choose to use them as required although it is recommended that they are used within the context of the definition of the alarm to avoid confusion.

Programmable Temperature Alarms

Tankvision Multi Scan NXA83B

These are operator programmable temperature alarms.

• Enabled – An operator configurable temperature alarm enable flag.

• High – An operator configurable high temperature alarm.

• Low – An operator configurable low temperature alarm.

• Hysteresis – An operator configurable temperature hysteresis value.

Programmable Water Alarms

Water alarms are triggered when tank water levels exceed the limits specified. If you do not require a low water alarm, set the low level to a negative value.

• Enabled – An operator configurable water alarm enable flag.

• High - An operator configurable free water level, above which the alarm will be triggered.

• Low - An operator configurable free water level, below which the alarm will be triggered

- If a low water warning is not required this may be set to a negative value to prevent it occurring.

• Hysteresis – An operator configurable free water level hysteresis value.

Difference Alarms

For applications where an accurate product level measurement is critical a tank may have 2 level gauges. One gauge will be nominated as Primary duty with the other as a Secondary gauge.

The Multi Scan NXA83B will monitor the level returned from both gauges and can check for a difference between the two gauge levels. If the difference exceeds the tolerance entered for this alarm a difference alarm will be generated.

The configurable fields are:

• Enabled – Tick to enable the alarm.

• Maximum Difference – Enter the maximum allowable difference between the 2 gauge levels.

• Hysteresis – An operator configurable level difference hysteresis value.

Deviation Alarms

The deviation alarm is used to alert operators to layering occurring in the tank. When two consecutive profile points deviate by the specified amount, either in their density readings or temperature, an alarm will be generated. This alarm requires the use of gauges capable of returning density profiles.

The configurable fields are:

• Enabled – Tick to enable the alarm

• Density Profile Deviation – Maximum deviation between consecutive density points.

• Temperature Profile Deviation – Maximum deviation between consecutive temperature points.

Programmable Density Alarms

These are operator programmable density alarms.

The configurable fields are:

• Enabled – An operator configurable density alarm enable flag.

• High – An operator configurable high observed density alarm.

• Low – An operator configurable low observed density alarm.

• Hysteresis – An operator configurable density hysteresis value.

Floating Roof Alarm

The purpose of the Floating Roof alarm is to provide the operator with the option of generating a warning when the product level starts to approach the point where the roof starts to rest on its legs. Under normal operating conditions this is generally undesirable; therefore the alarm has been provided for that purpose.

The configurable fields are:

• Enabled – When selected, the Floating Roof Alarm will be activated when the product level falls below the Roof Early Warning Level. The alarm will be cleared when the product level rises above the Roof Early Warning Level by more than the Roof Warning Hysteresis.

Database Configuration Tankvision Multi Scan NXA83B

• Roof Early Warning – An operator configurable set point determining at what level the alarm will be generated. The level would normally be programmed above the Roof Fully

Floating level set in the Tank Characteristics module.

• Roof Warning Hysteresis – The operator configurable distance by which the product level must return above the Roof Early Warning Level in order to clear the Roof Early Warning

Alarm.

7.6.2

Modifying Data Within Alarm Configuration

All alarms are tank specific. If the same alarms are required for more than 1 tank, they will need to be configured for each tank.

Open the Alarm Configuration window and select the tank from the list on the left.

Select the type of alarm to be modified for this tank.

The current details for the alarm for that tank will be displayed.

The Multi Scan NXA83B comes supplied with a set of default alarm parameters preconfigured. The first time Alarm Configuration is loaded after installing the system it will display the default values . These default values should be replaced with the correct operating values prior to commissioning the system.

Select the field to be edited and enter the new data values. The TAB key may be used to move to the next entry field or selection can be made using the mouse.

Each field is validated both during data entry and just before the data is saved to the database.

Once the changes are complete and correct, they can be saved by clicking the OK button.

This will save the changes and close the window. To save the changes and continue to edit the database click the Apply button. It is not necessary to save the changes to one alarm before editing another but it is best practice to do so.

To edit further tanks follow the same procedure.

When all necessary configuration has been completed, the changes can be saved and the

Alarm Configuration window closed by clicking the OK button. The window can be closed and changes can be abandoned without saving by clicking or the Cancel button, however any changes already saved will be retained.

7.6.3

Generation of Alarms

Normally in a standalone configuration the alarms are detected and generated by the Data

Communications Control module. It is this module that sees the changes in gauge data first.

In a client-server system it is the same module that detects and reports the alarms although it is important to note that this module will only be running on the server.

Any client connected to the server will therefore see the same alarms.

Some events may be generated locally by each client. These are normally events in response to abnormal operating data or transient or irrecoverable data access errors.

Enabling and Disabling Alarms

When an alarm is Enabled , the variable associated with the alarm is monitored against its set limits. If the variable deviates outside of the set limits an alarm will be generated.

When an alarm is Disabled , no alarm processing will take place for the disabled alarm and therefore no event, audible signal or otherwise will be generated if the variable deviates outside of its set limits.

The alarm configuration display provides a check box within each tab for enabling or disabling the alarm.

7.7 Manual Data

Normally tank data is collected from the field instruments automatically.

Where primary data values are not available or no longer available due to a gauge fault, data values may be switched from automatic mode to manual mode.

When in manual mode the data values must be provided by the operator.

Data that is in manual mode is normally displayed with green text on black background to signify that it is manual data. On reports it is normally suffixed with the letter M .

Where tanks are not fitted with gauges but are still required on the system, the tank may be operated with all of its primary data values in manual mode. In this way the tank inventory is calculated from the manual data.

Note that gauges that have both level and temperature in manual mode will not be polled by the communications layer.

Primary data values are those measurements made by the tank gauging instrument such as:

• Product Level

• Water Level

• Product Temperature

• Product Density

• Pressure

Traditionally, most gauges provide Product Level and Product Temperature measurement capability. It is quite common to find that the rest are entered as manual data.

More modern gauging instruments have the capability to measure water level, density and pressure automatically. In this case the values would be collected automatically.

The use of this feature can be controlled by the security system.

8 Display Configuration

8.1 Tank Data Displays

As an optional feature, the Tankvision Multi Scan NXA83B is equipped with a 7 in LCD touchscreen display which is used to view the live data from any tanks configured in the database. Navigation around the different displays is by selection of the touchscreen buttons.

The display can show data to in a number of different formats:

• Grid View display of multiple tanks

• Single Tank graphical display

• Multi Tank graphical display

• Reports of multiple tanks

A range of different displays can exist for each format, which may be selected for viewing by the operator.

These displays must be configured in the Tankvision Multi Scan Configurator software before being downloaded to the NXA83B device.

The configurator user is free to select from a range of data fields to display, such as level, temperature, density etc. Other features such as pictures, bar graphs, alarm displays, text label and selector buttons may also be displayed.

8.2 Display Configuration

The Multi Scan NXA83B has the capability to configure three categories of display:

• Single Tank Displays

• Multi Tank Displays

• GridView Displays

The first two use a SCADA editor to configure the displays. This makes them highly adaptable, enabling displays to be configured to exactly match user requirements.

GridView displays are equally configurable but use a grid layout to display data. These will be covered in a later section (

 ä 94).

There is no limit to the number of displays that can be configured.

To open the display editor open the Configuration menu and select the type of display to create or edit.

8.3 Single Tank and Multi Tank displays

The Multi Scan NXA83B single tank and multi tank displays are completely flexible for the data to be shown on the screen. They are configured using the Tankvision Multi Scan

Configurator software.

A display may be configured for a range of items, including:

• Live Data Fields – For measured data such as Level, Temperature, Pressure, Density,

Water Level etc. May also includes calculated data such as Volumes, Mass etc.

• Data Entry Fields – For manual data, alarm setpoints etc.

• Fixed Text Labels

• Bar graphs – For showing percentage level etc.

• Pictures

• Alarms

• Graphs – For Multi-element temperatures, profiles etc.

Each field can be customized for size, color, fonts etc.

Single Tank Displays only display data for gauges from a single tank name. The configured screen becomes a template for what to display, therefore display fields cannot be configured for a specific Tank and only the gauge duty may be specified. The tank is specified at runtime.

Multi Tank Displays are fixed displays where data from multiple tanks can be displayed on the same screen. All display fields must have the tank name and duty defined at the time of configuration.

8.4 Grid View and Reports

GridViews and Reports use a grid layout to display data either on screen or on paper (in the case of reports).

A range of Grid Views and Reports may be configured using the Tankvision Multi Scan

Configurator tool, using a common set of configuration screens.

Reports may also be configured to be automatically printed at scheduled times.

Grid Views and Reports are completely configurable. This makes the grids highly adaptable, enabling GridViews and Reports to be configured to exactly match user requirements.

Since GridViews are configured in exactly the same way as GridView Reports without the additional features of printing and report scheduling, this manual will only deal with

GridView Reports.

The grid can be customized for:

• the number of columns

• the tanks to be displayed

• column totals

• flow colours

• grid title text and font

Each column in the grid can be formatted for:

• Live Data such as Level, Temperature, Pressure, Density, Water etc.

• Width

• Font

• Header Text

A report may also be configured for print layout, including:

• Landscape/Portrait

• Margins

After installing the software only one account will exist. This is the Administrator account and it will have a default password of "password". It is recommended that this is changed to a more secure password as soon as possible.

The table is a matrix of users against their logon rights. The columns indicate the characteristics of the users account, and the rows represent the different users. It is therefore possible to deny or grant a level of access on a per feature basis (i.e. User A may be denied access to the Tank Characteristics module, User B may be granted Read Only access, and User

C may have modify privileges).

The fields are defined as follows:

• User Name : Text entry field for user’s name. This will be displayed on the Home Page when the user is logged on.

• User Initials : Optional text entry field for an abbreviated version of the user name. This is a reference only field that is not used by the Multi Scan NXA83B.

Gauge Command Scheduler Tankvision Multi Scan NXA83B

11 Gauge Command Scheduler

The Gauge Command Scheduler is a Windows service that can be configured to send gauge commands at a specific time of day on a recurring basis.

The Gauge Commands can be sent to a Single Tank, all Tanks, or a group of tanks generally specified by Gauge Type.

Care should be exercised when scheduling gauge commands, particularly those that affect a gauge’s primary measuring capability, as the tank may be involved in some sort of critical operation such as receiving product from a ship or similar.

The Gauge Command Scheduler can be configured via the Tankvision Multi Scan

Configurator tools.

11.1 Configuring Scheduled Commands

From the main page window, select the Tools  Command Scheduler Configuration menu item.

This will bring up the configuration application, which you can use tocreate, view and edit the scheduled commands.

A scheduled command can be configured to send a single command once a day by ticking the Specified start box and entering a time into the field below.

Commands can be sent at regular intervals by ticking the Command interval box and entering the interval period in the field below.

It is also possible to execute a command between two specified times and a specified frequency by ticking the Specified start , Specified stop time and

Command interval boxes.

For example, to send a command every hour between the hours of 01:00 and

04:00 you would set the start time as 01:00, the stop time 04:00 and the interval as 01:00.

When changes have been made to the schedule's detail, click Save to commit the changes to the database, or Cancel to discard them.

To create a schedule click New and edit the schedule as required. When the Save button is clicked this will add a new entry to the list on the left.

Gauge Commands and Remote Configuration Tankvision Multi Scan NXA83B

12 Gauge Commands and Remote Configuration

The Gauge Commands tool allows commands and configuration items to be sent directly to any gauges attached to the Multi Scan NXA83B and is included as part of the standard

Tankvision Multi Scan Configurator.

To run the Gauge Commands tool requires that the database loaded into the Configurator is the current live runtime database, and that the gauges are connected and communicating with the Multi Scan NXA83B.

Gauges currently supported by the utility are:

• Endress+Hauser Proservo NMS5, NMS80 and NMS81

• Scientific Instruments 6290 Densitometer

• Enraf 854 servo gauges and 873 radar gauges

• Motherwell Gauges

Gauge commands can be gauge specific and therefore dependent on the gauge type.

For instance for Enraf gauges the following functions are supported:

• Dipping

• Displacement

• Test Gauge

• Alarm

• Maintenance

• Gauge Items

Other gauges may support other command and configuration functions.

The operations carried out in the Gauge Commands tools affect the operation or configuration of the gauges, they do NOT affect the Multi Scan NXA83B directly.

12.1 Launching Gauge Commands
