Tankvision User access rights

5 User access rights

The Tankvision system has an inbuilt authentication mechanism to prevent unauthorized access. The system identifies the user by a unique logon name and password. The system records all the activities performed by each user and allows only a specific number of users from each user type to be logged in at the same time. This can be configured in system settings by an authorized entity. Each Tankvision unit has an option to confine user access rights data for local use within the unit or enable user access rights data for the central Tankvision unit thereby allowing the user to access all the units that are configured to the central Tankvision unit.

All in this manual described functionality is based on the default settings for the role of the "Operator". The operator is not allowed to perform any changes in the user access rights. In case the "Operator" is allowed to perform other operations than the ones specified with the default settings refer to the "Description of Instrument Functions" BA00339F/00/EN.

6.7 How to issue gauge commands

The below described operations can be performed with the default user access rights for an operator ("User access rights", → ä 13).

Every gauge supports a specific set of commands. The Tankvision system supports these gauges and stores their data and corresponding gauge commands in "gauge definition files". The functionality of gauge commands is dependent on the gauge type assigned to the tank, whereas completion of a gauge command is based on the gauge status or gauge commands status. The Tankvision system retrieves these commands from the "gauge definition files" during the configuration of gauge commands. Gauge commands can be scheduled and sent only by an authorized user. Most of these commands are unique for servo gauges. You can send a gauge command to a gauge installed on a tank manually or even schedule a gauge command to be sent automatically. Tankvision Tank Scanner prevents the user to send the same gauge command multiple times to a servo gauge (i.e. the Tank Scanner only sends gauge command once to the servo gauge and ignores the gauge command until a new command is requested). This applies for gauge command requests via the Host Link, OPC DA or the web interface. In case a gauge command has been given to the servo gauge via a separate way (e.g. directly from the display), then the Tank Scanner will not get this information. In this case simply by sending a different gauge command and switching back to the gauge command will solve the issue.

6.7.1 Schedule Gauge Command

The Tankvision system allows the user to schedule gauge commands, such that they can be executed either immediately or at a certain time. An operator can schedule a gauge command only if that particular gauge command is enabled in the Gauge Command configuration screen.

6.8 How to view a real time trend

The below described operations can be performed with the default user access rights for an operator ("User access rights", → ä 13).

The Tankvision system collects data from the tanks and monitors these values using a trend. A trend is a line graph which gives a pictorial representation of the recent changes of the measured values over time. The Real Time Trend is hosted in the Tankvision unit. It depicts the real-time measured or calculated values of a selected tank as a function of time in the form of a line chart. The system has default settings which can be customized as required for each tank element and will eventually be plotted on the trend. Up to 4 values can be plotted in one chart.

6.10 How to do Product transfer

The below described operations can be performed with the default user access rights for an operator ("User access rights", → ä 13).

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 44) will mention the W&M approved status, which can be used to prove that the correct amount of product has been transferred.

6.10.1 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

6.13 How to do tank calculations

The below described operations can be performed with the default user access rights for an operator ("User access rights", → ä 13).

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.

To use the tank calculator

Click the Tank Calculator tab. Tankvision displays the screen as follows:

NXA82x_Tank_Tank-Calculato r--Tab

Column Description

Parameter This column displays a list of product parameters for which the start and end value can be

entered for the purpose of calculation.

Start Value Enter the appropriate start values for the relevant parameters in the corresponding text

boxes. The start value is the initial value of the parameter. For example, the initial level of the product will be the start value for Product Level. The data type for this field is numeric.

End Value Enter the appropriate end values for the relevant parameters in the corresponding text

boxes. The end value is the current or final value of parameter. For example, the current or final level of the product will be the end value for Product Level. The data type for this field is numeric.

Delta Value The delta values are not editable. The delta value is the difference between the start value

and the end value of a parameter. The data type for this field is numeric.

Enter the appropriate information in the relevant fields and click the Calculate button.

The below described operations can be performed with the default user access rights for an operator ("User access rights", → ä 13).

6.18.1 Overview of the Alarm and Event Panel

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

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

Click the Alarm tab. Tankvision displays the alarm information as follows:

6.18.2 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 Is Set off

HH High High Alarm Whenever the value of a data element raises 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.

HA High Alarm Whenever the value of a data element raises 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.

MF Max Fill Alarm The Max. Fill Alarm (MF) is indicating that the tank which is filling has

reached or exceeded the Normal fill level.

The normal fill level (normal capacity) may be defined as the level to which the tank will intentionally be filled on a routine basis, using the normal process control system. The normal fill level will be dependent on the preceding levels and should be sufficiently far below the LAH to avoid spurious activation, e. g. due to level surges during filling or thermal expansion of the contents. This level is also called Maximum working level.

Enter the appropriate value for the Max. Fill Alarm set point. This set point is used to detect whether any of the following parameters have reached their respective MF alarm value, namely: Product Level.

The MF Alarm set point should be less than the HA alarm for the corresponding parameter and less than the Gauge Reference Height. The data type for this field is numeric.

LA Low 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.

LL Low Low 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.

CH Change 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 45).

Tankvision Operations

Sub Type Description Is Set off

DF Difference Alarm 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.

FL Fail Alarm Whenever the gauge status received from a gauge indicates that the gauge

has failed.

CO Gauge

Communication Error Alarm

TO Time out / Age

Alarm

SE Flash drive is full Whenever the the flash drive is full (e.g. due to archived data).

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

Whenever the data received from a gauge is too old.

6.18.3 Alarm Color Schemes

The Tankvision system highlights the alarms using different text and background colors to indicate the priority of each alarm as shown in the figure below.

Alarm_Overview

Background Color Text Color Indicates

Dark Green Bright Yellow An active and acknowledged alarm

Light Red Bright Yellow An active and unacknowledged alarm

Yellow Red An inactive and unacknowledged alarm

White Black An inactive and acknowledged alarmed

6.18.4 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

Double-click the alarm in the alarm summary.

Alarm_Overview

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.

6.18.5 Alarm Pop up Agent

• The Alarm Pop up Agent is a windows program installed on a PC, connecting to NXA820/

NXA821.

• The program is running in the background and scans for alarms generated in NXA820/

NXA821.

• If an alarm is present, a pop up window opens displaying the alarm.

• The alarm can be acknowledged within this window.

• The window can only be closed if no alarm is active.

• Multiple NXA820/NXA821 can be configured with single Alarm Pop up Agent application

In case an alarm is present the Alarm pup up agent pops up and stays in front of all open windows (and can’t be closed with an active alarm). Also a horn sound is present (for the Max. Fill alarm (MF) the sound is different to the other alarms as is has a lower severity).

By selecting one alarm in the left list more information is shown on the right side:

Alarm-Popup-Agent

With clicking on the button Mute the sound can be switched off. By clicking on the button Summary a browser window/tab opens showing the present alarms and events (→ ä 63, "Overview of the Alarm and Event Panel"). By clicking on ACK the alarm gets acknowledged in the pop up agent and the system (also in Tankvision user interface the alarm is acknowledged). The alarm disappears from the pop up window and the acknowledgment gets recorded in the event log.

Also in the pop up agent the color scheme is followed: Inactive alarms are indicated like in the picture below.
