Configure Tank Monitoring Analysis Rule
The Tank Monitoring Analysis Rule requires a set of control parameters. The control parameters consist of generic information that must be set to allow the application to run with the proper parameters.
The required control parameters can be configured in the Tank monitoring Configuration window under the Control Parameter tab, as shown in the following figure.
Note: The Plug-in Configuration tab is disabled, if a license file is not installed, or it the license has expired. In such instances, the parameters for the cut-off configuration are enabled.
The table below lists the control parameters that must be set for the Tank Monitoring Analysis Rule.
Tank Monitoring Analysis Rule - Control Parameters
| Parameters | Description |
|---|---|
| Publish to element | If selected, the attribute value is stored not only at case level, but also at database level, so that they are readable without entering into the case. |
| Trace Log File | If selected, specific log messages for tank monitoring are added to the standard AF trace. |
| Event Table | Th AF table used to store the event messages (LOG). |
| Unit of Measure | The Tank Volume Unit of Measure (UOM). |
| Consistency Status Digital set | The digital set used for “Tank consistency status”. |
| Movement Status digital set | The digital set used for “Tank movement status”. |
| Delta Stock Shift | The time expressed in minutes (default 10). It is the time range to calculate the Delta Stock used in the Tank monitoring. |
| Volume / Mass Option | The default is 'Volume Option': in this case delta stock is calculated using Volume. If Mass is selected, the Volume is calculated starting from Mass (and density must be available). |
| Use Automatic Split and text box | If selected, an offset is set to split the daily transfer; the transfers that are active are automatically closed and re-opened at this time, with the same attribute values, except the measured mass quantity which is set to 0. |
| Update movements values with tanks data | If selected, it enables the cut-off procedure to record, in the transfer attributes, the information about the Tank source or destination at Start and End Time. |
| Automatic ACTIVE Transfer Closure | This optional section lets you configure the date and time that all the active transfers will be closed. Once an active transfer is closed, the daily cut-off is no longer applied.Three options are available: OptionDescriptionClose Active transfers after ____ daysAll active transfers will be closed after a predefined number of days from their activation date.End of MonthAll active transfers will be closed at the end of the month.End of WeekAll active transfers will be closed at the end of the week. You can choose the day of the week to activate the procedure.Note: The activation time of the active transfer closure procedure is according to the configured cut-off time. |
| Option | Description |
| Close Active transfers after ____ days | All active transfers will be closed after a predefined number of days from their activation date. |
| End of Month | All active transfers will be closed at the end of the month. |
| End of Week | All active transfers will be closed at the end of the week. You can choose the day of the week to activate the procedure. |
| Timeout for alarm (sec) | The period after which the alarm status is confirmed. |
| Use DCS Tank Status for Tank Monitoring and TankStatusAttribute and Status Definition | A parameter that is set if the alarm status is managed by the DCS with a tag that assumes integer values. If this is the situation, the TankStatusAttribute contains the digital set state in PI and the ordered status translates the values None, Input, Output, and In/Out. |
| ManageTank Warning for planned not started and text box | If selected, the tank assumes the status NOT_STARTED, if a planned transfer has not been started yet after the defined timeout period. |
