3.4.5

Subscription Store definition

In a typical Tankvision system, most configuration settings are common for all Tankvision units within the network. Therefore, the time required for the configuration of the system can be minimized by defining one of the units to be a Subscription Store. The configuration settings are only performed on this Subscription Store. These settings are then distributed to the other units within the network.

For each Tankvision unit (i.e. Tank Scanner NXA820, Data Concentrator NXA821 or Host

Link NXA822) within the network it is necessary to define if it is a Subscription Store or if it receives its configuration from a Subscription Store.


1.



2.

Click follows: on

NXA82x_Define-Configuration-Store-Details

3.

For the Subscription Store:

• In Configuration Store Type select the option Subscription Store (Default)

For the other units

• In Configuration Store Type select the option Use Global Configuration Store

• In Subscription Store select the Subscription Store to which this unit is to be linked

• In Allow Local Configuration Change define whether local configuration changes of this unit are allowed in case the Subscription Store is not available.

4.

5.

Click the Submit button to proceed, or click the Refresh button to reset the screen.


With the (recommended) use of global configuration store the following information is transferred to the subscription units:

• Customer settings like site information (without customer specific logo), unit, email server and day and time settings (configurations of languages and printer agent must be done for every single device)

• Environment settings

• Products

• Users incl. user access rights

Global settings could be changed later on, also after assigning other units. It is highly recommended to use a NXA820 as subscription store.

3.4.10 Configuration of W+M systems

Description of the sealing process

Locking mechanisms in Tankvision:

Connected PCs are registered in the system by assigning the MAC address. Once the system has been locked, only these PCs are accepted and can display calibrated data.

When the W+M switch is flipped, a checksum is calculated and set.

This calculation is repeated every 8 hours. If this checksum deviates from that at the time of sealing, changes have been made to the system. It is no longer possible to modify W+M parameters, such as tank tables, units and print templates, once the W+M switch has been flipped.

Recommended procedure:

It is recommended to start calibrating the tank gauging system from the field devices via possible protocol converters and finish the process with the Tankvision inventory management system. When calibrating the Tankvision Tank Scanner or Data Concentrator, it is recommended to start with the unit used as the Global Configuration Store since the engineering units are configured centrally here. These units would then not have to be

checked separately in the boxes assigned (see "Units", → ä 26).

A modified checksum indicates that changes have been made to the system. The checksum must be documented (e.g. by printing out the screenshot, see Figure "Tankvision W&M Seal") and recorded in the acceptance report (e.g. by attaching the printout).

The checksum can be recalculated by switching the Field Scan off and then on again.

Checking the W&M display

The following steps must be taken to check the weights and measures display:

• The settings listed under "Sealing tank data" (→ ä 33) can no longer be modified.

• A WM in front of the values for the Product Level, Product Temperature and Total

Shell Details

The tanks are often made of iron, steel or other suitable alloys. The tank shell often undergoes dimensional changes as a result of thermal expansion. The change in dimension of the tank shell results in a change of the apparent product level, thereby introducing an error in the subsequent volume calculations. The volume therefore needs to be corrected by the Correction of the Tank Shell Deformation (CTSh) based on the tank shell details configured for a tank.

The Shell Details screen allows you to view and modify the details of the tank in terms of the tank shell thermal expansion coefficient, insulation factor, etc.

Floating Roof

A tank can often have a floating roof. A floating roof is called so because it floats on the product stored in the tank. The roof moves up or down along with product level. Since the roof is floating on the tank, it displaces some amount of product depending on the weight of the roof and the density of the product. This displacement in product level results in a different apparent level, introducing an error into the volume calculations. The product volume therefore needs to be corrected.

A floating roof often has supporting legs. The roof can be rested on these legs when the level is too low or the tank is empty. This allows maintenance staff to enter below the roof for carrying on tank maintenance. Based on the product level, the floating roof can be landed on the legs or floating on the product. However, in a certain range of product level, the floating roof can be partially landed. This zone is called 'critical zone'. In the Tankvision system there can be two critical zones related to the position of the floating roof legs.

The fields in the Floating Roof screen are enabled if the Tank Type in the General Details screen is selected as Tank with external floating roof, without stilling well, Tank with external floating roof, with stilling well, Tank with internal floating roof, without stilling well, or Tank with internal floating roof, with stilling well.

If the Tank Type is selected as Tank with Fixed roof, without stilling well, Tank with

Fixed roof, with stilling well, Open Tank, Spherical Tank, or Bullet tank, the fields in the

Put Tank into Calibrated Status

Tankvision generates various tank inventory reports and displays tank inventory data on web pages. A report or data displayed on the report can be W&M approved only if the tank is W&M calibrated. The user can set the tank and tank parameters into the W&M calibrated status. Once the tank is set in the W&M calibrated status, it means the tank configuration is

W&M approved.

Subsequently, the system becomes W&M approved only after the W&M switch is "closed".

The W&M switch is protected by a mechanical W&M seal (sticker). Only a W&M official or an accredited person can put the W&M seal.

The configuration of a tank that is marked as W&M calibrated cannot be modified after the

Hysteresis Value

Hold off Time

(seconds)

Enter the appropriate Hysteresis Value in the text box.

The hysteresis is applied to the respective alarm set points to prevent false toggling of the alarm status between "active" and "inactive" which might happen due to fluctuations in the measured value. For example, the product level could fluctuate due to waves on the product surface.


Enter the appropriate hold off time in the text box.

The hold off time is triggered when the actual value crosses the configured set point for an alarm. The alarm becomes active only after the actual value stays above or below the respective alarm set point for a time more than or equal to the hold off time. This prevents false alarm generations due to spikes in the actual values of data.

This column displays different parameters for which the set points are configured.

This column displays the current value of the corresponding parameters.

Enter the appropriate value for the HighAlarm set point. This set point is used to detect, whether any of the following parameters have reached their respective HA alarm value, namely: Total Observed Volume (TOV), Gross Observed Volume (GOV), Gross Standard

Volume (GSV), Mass in Vacuum and Flow Rate. The data type for this field is numeric.

Enter the appropriate value for the LowAlarm set point. This set point is used to detect whether any of the following parameters have reached their respective L alarm value, namely: Total Observed Volume (TOV), Gross Observed Volume (GOV), Gross Standard

Volume (GSV) and Mass in Vacuum. The data type for this field is numeric.

Select the appropriate check boxes to enable the data fail alarm for the relevant parameters.

Clear the appropriate check boxes to disable the data fail alarm for the relevant parameters.

Enter the appropriate Hysteresis Value in the text box. The hysteresis is applied to the respective alarm set points to prevent false toggling of the alarm status between "active" and "inactive", which might happen due to fluctuations in the measured value. For example, the product level could fluctuate due to waves on the product surface. The data type for this field is numeric.

Enter the appropriate hold off time in the text box. The hold off time is triggered when the actual value crosses the configured set point for an alarm. The alarm becomes active only after the actual value stays above or below the respective alarm set point for a time more than or equal to the hold off time. This prevents false alarm generations due to spikes in the actual values of data. The data type for this field is numeric.

The "Product Transfer" tab

The product transfer is a day-to-day tank farm operation. During the tank farm operation, a product is pumped into or out of a tank. A tank may receive product from a pipeline, tanker, ship or another tank. When the product is to be filled into a tank, it is necessary to check the available tank capacity. Similarly, when the product is to be pumped out of a tank, it is necessary to check the product volume in the tank. Tankvision allows an operator to create a new product transfer.

Tankvision does not control the product transfer, but it monitors product transfers and generates product transfer data and reports. When a company sells the product stored in tanks to another company, it is important that the tank is W&M (weights and measurement) certified for correct measurements. The Tankvision system provides this facility by calibrating the system and then gets it W&M approved. All tanks which are W&M certified can be used for custody transfers.

In this case the product transfer report (→ ä 88) will mention the W&M approved status,

which can be used to prove that the correct amount of product has been transferred.

8.7.1

Product Transfer Life Cycle

The Tankvision system allows the user to create, finish or abort a product transfer. Once a product transfer is created, the system monitors the product transfer to detect "start of transfer (active)", "product transfer paused" or "product transfer completed".

The life cycle of a product transfer

The product transfer traverses through its life cycle as follows:

• Create a product transfer for a tank

• Detection of the start of the product transfer

• Detection of a paused transfer

• Detection of a completed transfer

• Transfer finished or aborted

• Product transfer report

Status of a Product Transfer

Create a New Product Transfer

Creating a new product transfer is the first step to be followed after the pre-condition for product transfer is set in the system. While creating a new product transfer, the transfer status of the tank should be "None". The product transfer status "None" means that the tank does not have any product transfer associated with it in the Armed or Active status, and thus a new product transfer can be created. An image of Tankvision displaying the status as

"None" is as follows:

Validate product transfer details

Once the user has created a new product transfer for a tank, this tank is said to be "Armed" for product transfer. The system starts monitoring a tank (with status) "Armed" to automatically detect the start of the product transfer. Auto detection of start of Product

transfer defined in Chapter "Flow Calculation", → ä 49). Once a tank is armed for a product

transfer, no other product transfer can be created for the tank, unless the existing transfer is cancelled.

An image of Tankvision displaying the status as "Armed" is as follows:

The system generates an event when the status is changed from "None" to "Armed". This information can be viewed in the Event or Alarm & Event tab.

Endress+Hauser


Detection of the start of a product transfer

Once the product transfer has been armed, the system detects the start of the product transfer based on a change in the level and the rate of change of the level. The system treats the product transfer as started and the product transfer status is changed to "Active" if:

• The change in product level is greater than the minimum level change, and

• The rate of change of level is greater than the minimum rate of change of level configured under the flow calculation details

Once a tank is in the "Active" status for a product transfer, no other product transfer can be created for the tank, unless the active transfer is Finished or Aborted.

The "Tank Calculator" tab

The Tankvision system performs inventory calculations based on the measured data scanned from a gauge or entered manually. The system uses the tank and product configuration mainly to perform these calculations. Tankvision provides a tank calculator to evaluate various 'what if' scenarios. These scenarios could be:

• What would be the product volume for a certain product level?

• What would be the product level, if a certain quantity of product is pumped into the tank?

• What would be the product volume, if the product level is equal to the high level alarm?

Based on the above mentioned scenarios, the tank calculator would also indicate whether the resulting tank parameter could cause an alarm.

Thus, prior to an actual product transfer, the tank calculator can be used to verify whether it is possible to perform an "out" or "in" product transfer without resulting in an alarm.

Any tank parameter that is changed in the tank calculator is used to carry out calculations and display results to evaluate the what-if scenarios. Changing tank parameters in the tank calculator does not change the actual tank data.

A tank group is a collection of tanks. In the Tankvision system, tank groups are configured for better management of tanks. There are two types of tank groups:

• Static Tank Group: A static tank group is created by selecting tanks available in the system.

For a static tank group, the user must select the appropriate tanks available to form a tank group. All selected tanks in a particular static tank group will be displayed on the screen.

The screen will display the tank data dynamically on a real time basis.

• Dynamic Tank Group: A dynamic tank group is created by defining filtration criteria. For a dynamic tank group the user does not select the tanks. Instead, the user can define selection criteria using filters on tank elements such as Product, Location, Tank Type and

Tank Status. The screen will display the tank data dynamically on a real time basis for those tanks in the tank group meeting the dynamic tank group settings. For example, if a tank group is configured with active alarms, then whenever the tank has an active alarm, the tank will be shown in the tank group with active alarms.

To configure tank groups

1.

On the Navigation Tree, click the Customized Groups header. (The number of tank groups configured is displayed in brackets next to the Header’s name).

The graphical and tabular format give a quick feedback about the current tank status. The screen displays the tank data dynamically on a real time basis. The graphical and tabular page shows the tanks in the selected tank group.

Each tank is shown with its tank parameters. There are two types of Tank Groups:

1. Static Tank Group: Tank group created by user

2. Dynamic Tank Group: Tank group created by defining filtration criteria. (e.g. All tanks in locked status)

Both types of tank groups are supported with real time graphical information.

The tank group details are viewed by two types of users, viz. operator and guest. The user logging into the system as an operator can view the real time tank group details. The user logging into the system as a guest can view the non-real time tank group details. A guest user has a minimal access to the Tankvision functionality. A guest user can view the tank details, gauge details, tank group and tank overview (all tanks on a specific Tankvision unit) in a non-real time mode.

12.1.6 Configuration Store definition

In a typical Tankvision system, most configuration settings are common for all Tankvision units within the network. Therefore, the time required for the configuration of the system can be minimized by defining one of the units to be a Subscription Store. The configuration settings are only performed on this Subscription Store. These settings are then distributed to the other units within the network.

For each Tankvision unit (i.e. Tank Scanner NXA820, Data Concentrator NXA821 or Host

Link NXA822) within the network it is necessary to define if it is a Subscription Store or if it receives its configuration from a Subscription Store.


1.

Login to the Tankvision unit and navigate to the Global Settings screen as described in

Section 12.1. Click on Customer Settings.

2.

Click follows: on

123



3.

For the Subscription Store:

– In Configuration Store Type select the option Subscription Store (Default)

For the other units

– In Configuration Store Type select the option Use Global Configuration Store

– In Subscription Store select the Subscription Store to which this unit is to be linked

4.

5.



With the (recommended) use of global configuration store the following information is transfered to the subscription units:

• Customer settings like site information (without customer specific logo), unit, email server and day and time settings (configurations of languages and printer agent must be done for every single device)

• Environment settings

• Products

• Users incl. user access rights

Global settings could be changed later on, also after assigning other units. Its highly recommended to use a NXA820 as subscription store.

124 Endress+Hauser


12.1.7 Define Configuration Store Details

The Tankvision system is a distributed system, which comprises several Tankvision units working together in a single network. The configuration for most of these units is common.

Hence, these configuration settings are performed in one single Tankvision unit, which acts as a subscription store. A subscription store minimizes the time taken for configuration and avoids any duplication of activity in the Tankvision system. It circulates its configuration to other Tankvision units in the form of Global Settings. Sometimes, a Tankvision unit might need to use global configuration settings that are different from the subscription store. In this case, the Tankvision unit’s settings can be configured by using a local configuration, so that it neither affects nor is affected by the subscription store.

To define configuration store details

1.

Click follows: on

Endress+Hauser


Field

Configuration Store

Type

Description

Click the appropriate option to select the relevant configuration store type for this

Tankvision unit.

Subscription Store: This option configures the NXA unit to act as "Global Subscription

Store". Other units can subscribe to this subscription store to get the global configuration.

Any part of the global configuration changed on the subscription store is also updated on the subscribing units and vice versa.

Use Global Configuration Store: This option enables the NXA unit to use an existing

Subscription Store for global configuration. If the system is configured to use the global configuration store, the unit subscribes to the global subscription store to receive any configuration changes.

Use Local Configuration Store: This option enables the NXA unit to use the local configuration, which is different from that of the global subscription store. Any global configuration changed on the global subscription store does not affect the NXA unit configured to use local configuration store and vice versa. The configuration is not accessable for other units (unlike the subscription store).

Subscription Store Select the appropriate subscription store. This field is used to refer to a subscription store when the Tankvision unit is configured to use a global configuration store. This field is enabled only if the Use Global Configuration Store option is selected. This field displays a list of the Tankvision units configured as a subscription store. To get the latest list of global subscription stores, click the Refresh button.

2.

3.

4.

When the subscription store becomes active in the network, the global configuration settings at the subscription store overwrite the global configuration settings on all other Tankvision units. Thus, any changes made to the global configuration locally will be lost.




An event is generated after configuring the Subscription Store. The event details can be viewed in the Event or Alarm & Event overview.

12.11.4 Import Modbus Register Map for Parameters

The Modbus register map provides information about the mapping of MODBUS registers to the appropriate tank parameters.

The Modbus register map for tank parameters can be configured in an XML file.

The XML file can be developed in two different structures, viz, "simple approach" and "XML with orientation". In the simple approach the register addresses for all the parameters are explicitly provided by the user in XML.

In the XML with data orientation approach the register addresses are generated implicitly based on the orientation type and the block addresses provided by the user.

The orientation can be data or elements. If the orientation type is elements, then all tanks of one parameter are grouped in consecutive registers.

If the orientation type is data, then all the parameters of a tank are grouped. When the orientation parameters are grouped according to the orientation specified, the groups formed by the orientation are called blocks, and the address of the first register of the block is the block address.

NXA822 helps the user to import the XML file containing the tank parameters configuration from an appropriate network location.

12.11.7 Entis Host Protocol

Introduction

Introduction Entis+ host protocol

Enraf provides for their tank systems Entis+ the Entis Host protocol to connect to host system. The physical layer is normally the RS232 interface, but in our case also RS484 is possible.

Protocol structure

The protocol is designed as ASCII-Protocol. The transmission flow is quite simple:

The Host sends a request and the "Entis system" must answer. There is no special handshake between both. The telegram is starting with STX (Hex02) followed by data. The data and additional information are separated by a separator sign. The telegram is ending with an

ETX (Hex03). A Block control character is added, either before or after the ETX. The structure is as following for the Host request:

[STX]<request code no.><name><command, request><data><[ETX][LRC], e.g for an Entity request code 1. [STX]1TNK-01[ETX][LRC]

The answer telegram is depending on the packet type requested:

[STX]<execution code>/<name>/<data>/[ETX][LRC], e.g. for an Entity request code 1.

[STXJ0/TNK-01/07-28-92/11:58:24/_269/-1-/+/_21.0/-/NORMAL/B/_727.40/

_32.65/_27.62/_20.09[ETX][LRC].

The execution code indicates the status of the reply package:

• "0" request executed successfully

• "1" request NOT executed successfully

• "2" the last entity in a successfull group request

Supported codes by the NXA822 are:

1. The entity request, code 1, which is used to get the data of one tank.

2. The group request, code 2, to get the data of all tanks a defined group.

3. The download command, code 3, to write a density value to a tank on the NXA820.

174 Endress+Hauser


Configuration

The configuration of the Entis host protocol consists of two different parts:

One is the Web-based configuration of the protocol properties, the other part is the XMLbased settings of the tank names and groups.

Selection Entis Host

To use the Entis host protocol select in system in the Host link menu the submenu Hostlink

Configuration. In Hostlink protocol select Entis+ and submit.

NXA822_Host-Link_Host-Link-Configuration_Entis_Drop-Down

The following screen will be displayed:

NXA822_Host-Link_Host-Link-Configuration_Entis

The file has to be downloaded like the Hostlink configuration XML-file:

In the Hostlink configuration menu select Import Tank Map XML For Entis. Then you can download and submit the tank map for the Hostlink.

Endress+Hauser

NXA822_Host-Link_Host-Link-Configuration_Entis_Success

If the syntax of the XML file is correct the date will be accepted.

A XML file has to be created defining group names and tank names to specify what can be polled by the Host.

The important tags are:

1. Group tag: <GROUP_ENTRY NAME="Group name">

2. Tag to specify the NXA820 source: <HOST NAME="QNX224">

3. Tank name tag: <TANKNAME>Tank name</TANKNAME>

The group name and tank name must match the specified name length in the protocol (6 or

8 characters maximum length). The names are either included in the start tag (group,

NXA820 name) or between start and end tag (tank name).

Entis host refers to a tank with tank name and therefore it is important that tank names are unique across NXA820 units.

See below a sample XML for import file:

Common protocol configuration

The configuration of the Entis+ protocol consists of four submenus to configure:

1. Communication protocol settings

2. Entis+ Envelope settings

3. Numeric settings

4. Reply package settings

Entis+ standard host communication protocol settings

The protocol settings define the usual settings for a serial ports like baud rate, parity stop bits a.s.o.

Field

Field Separator character

Decimal separator character

Host requests as events

Description

The field separator character divides the individual fields in a reply packet, to make it more readable. You can choose any available character as the field separator.

You can choose to separate the integer and fractional part of values in a packet with either a comma (",") or a point (".").

You can choose to record every request the HOST makes in the list of events. If the HOST is making frequent requests it is better to disable this option otherwise the <F9> event screen will be swamped when you run the Master Program. But if only occasional request are made, enabling Ws option provides a good means of monitoring Host communications.

Selection of the telegram end character. The default is STX but any unused ASCII character is available.

Selection of the telegram end character. The default ist ETX.

Packet [START] character

Packet [END] character

Type of [LRC] calculation

Position of the [LRC] byte

In Host communications longitudinal redundancy checking helps detect corrupted packets. You can choose from the following checks:

• No Check:

If the protocols used by the HOST do not have LRC checking, the LRC facility may be disabled. In this case, the only checking will be parity checking (see communication protocol above).

• Odd Parity

This is defined by ANSI X 3.28 as follows: The BCC is generated by taking a binary sum independently (without carry) on each of the seven individual levels of the transmitted code. At each level, the number of one bits (including any in the BCC) is odd. In the summation, the STX is excluded when it is selected and the ETX is included.

• Even Parity

The same as above except that the number of one bits is even.

You can choose to have the LRC byte before the end character or after it. If you select the

LRC byte to appear before the end character, it will be inverted when it happens to be the same as the end character. So, if your end character is [ETX], ordinal 3, and in one instance the LRC also happens to be [ETX], then the LRC is inverted to 127-3, the ordinal

24. (For 8 bit words this is 255-3, the ordinal 252). For example, with the LRC after the

End character:

Request record for TANK-1: [STX]1TANK-1[ETX][LRC]

And with the LRC before the End character:

Request record for TANK-1: [STX]1TANK-1[LRC][ETX]

Start character in

[LRC] calculation

You can select whether the start character should be included or excluded in the LRC calculation. Normally it is excluded.

Filler for invalid data A field which is undefined or invalid due to a fail condition will have all the character positions filled with this character. You can select any available character, the default is

"*".

12.13 Operator Workstation Settings

Like any other web based system where users access the system via a web browser,

Tankvision uses the concept of user sessions to maintain user specific data for a session of user interactions with the system. A new session is created whenever an user accesses the system via a web browser. The user session is automatically removed after a session timeout, which occurs after a certain interval of user inactivity.

The Tankvision system uses user sessions to hold user settings and user data changed by the user. The session is also used to validate user credentials. User credentials are used to verify the user’s access rights to change the system configuration.

However, while viewing tank data using the system, it is essential that operators are able to view the data in an unobstructed manner without having to logon again and again as a result of session timeout. This is accomplished by identifying a certain computer as an "Operator

Workstation". If the Tankvision web pages are accessed from an operator workstation, the user can view the real-time tank information in an unobstructed manner once the user has logged onto the system.

Safety Stock KPI

The Safety Stock KPI indicates how often the volume of a tank has undershot the "Safety

Stock Volume" during the selected period. The Safety Stock Volume Point is set by the TOV

LA alarm. Therefore it is necessary to set the LA alarm for each tank.

The Safety Stock KPI is calculated using the currently set LA alarm. Thus, the LA alarm can be set retroactively.

Overview of the Alarm and Event Panel

The Alarm and Event Panel of the Tankvision system displays an overview of the Alarm and

Events generated by the system. The system will also pop up the message to the user in the local personal computer if an alarm pop up application is installed on that workstation.

17.1.1 Alarm Summary

Alarms:

Alarms are conditions pertaining to the functioning of the Tank or Tank elements. These conditions must be communicated to the user. The user may take the necessary actions based on the critical alarm displayed on the screen. These conditions are pre-defined by the user with valid access rights (for example, supervisor/ technician) while configuring a tank and the tank elements.

The Tankvision system is configured to raise various alarms based on measured data, calculated tank data, and alarm settings. The system continuously monitors the measured and calculated data and compares them with the preset alarm conditions such as Hold-off time and set point values. Whenever the value of a measured datum deviates from the set point value and remains deviated for a time span greater than or equal to the hold-off time, the system raises the appropriate alarm. The alarm will appear in the Alarm overview tab on the respective unit. The Operators receive the alarm notification on their computer screen in the form of a pop up window.

To view the alarm Summary

Types of Alarms

Alarm Sub-Types:

The Tankvision system raises different types of alarms depending on the value of a data element such as product level, temperature, pressure, etc. in comparison with the set point.

Different alarm types are described in the table below.

Sub Type Description

HH

HA

MF

LA

LL

CH

DF

FL

CO

TO

High High Alarm

High Alarm

Max Fill Alarm

Low Alarm

Low Low Alarm

Is Set off

Whenever the value of a data element rises above the HH set point and remains there for an interval greater than or equal to the hold-off time for the alarm.

Data Elements that set off alarms when they deviate from the predefined set point value, are as follows:

Product Level, Temperature, Pressure, Density, Product Secondary level,

Water level, Vapor pressure, Vapor temperature.

Whenever the value of a data element rises above the HA set point and remains there for an interval greater than or equal to the hold-off time for the alarm.

This alarm sub-type is similar to HH but with lower severity than HH.

The set point for HA is lower than the set point for HH.

Whenever the product level value rises above the MF set point and remains there for an interval greater than or equal to the hold-off time for the alarm.

Whenever the value of a data element falls below the LA set point and remains there for an interval greater than or equal to the hold-off time for the alarm.

Whenever the value of a data element falls below the LL set point and remains there for an interval greater than or equal to the hold-off time for the alarm.

This alarm sub-type is similar to LA but with higher severity than LA.

The set point for LL is lower than the set point for LA.

Change Alarm

Difference Alarm

Fail Alarm

Whenever the rate of change of the data element level increases above the

CH set point and remains above there for an interval greater than or equal to the hold-off time for the alarm.

This alarm is raised only when the tank is in the "Locked" status (→ ä 84).

Whenever the absolute value of the difference between product level and product secondary level increases above the DF set point and remains there for an interval greater than or equal to the hold-off time for the alarm.

Whenever the gauge status received from a gauge indicates that the gauge has failed.

Whenever the communication with a gauge fails due to a timeout error.

17.4

Acknowledging an Alarm

One of the important aspects of an alarm is alarm acknowledgement. As long as an alarm is not acknowledged, a new alarm of the same kind for the same tank is not generated, even if the related datum again crosses the configured set point. Therefore, a new alarm of the same type is generated only after the current alarm has become inactive and has been acknowledged by the user.

Alarm acknowledgment ensures that the alarm condition has been brought to the notice of operators. Alarms can be acknowledged from the Alarm summary displayed in the Alarm and Event Panel of the user interface or alarm pop up agent, or from a host system connected to the Tankvision system.

To acknowledge an alarm

1. Click the "ACK" button in the Option column.

When more than one user acknowledges the alarm at the same time, the system will record the first user as a user who acknowledged the alarm. For all other users, the system will display the error message “Alarm has already been acknowledged”.

Error Messages

1. "You Do Not Have Access Rights to Acknowledge Alarms!"

This message appears if you do not have authority to acknowledge an alarm. Only the user with valid access rights (for example, supervisor/ technician) can acknowledge an alarm.

Tankvision Comm DTM for FieldCare

19 Comm DTM for FieldCare

The NXA82x Comm DTM makes it possible to use the FieldCare for remote diagnosis and configuration of field devices. The Comm DTM connects automatically to the devices by sending the tank name to which the system must create a HART tunnel. The Comm DTM is downward compatible to older NXA82x firmware.

If you use older firmware than V01.05, the HART tunnel must be created manually; the setting of the Tank Name will be ignored.
