To save time and ensure performance, you need a product that will take data from all of your devices and calculate line segment energy results. LinePack is a fully configurable add-on product for Autosol Communication Manager® (ACM) and Schneider Electric’s SCADA Expert ClearSCADA. Designed to perform line segment energy calculations between two RTUs or devices with up to four different pipe sizes, this product can add calculations together to create a total system/pipeline value. Data is stored in the SCADA Expert ClearSCADA database or viewed in the LinePack application.

LinePack Features

This product offers customizable segment functionality, supporting the American Gas Association (AGA) gas flow measurement methods Gross1, Gross2, detail and manually entered FPV and offering multiple averaging methods for pressure and temperature. LinePack can use only upstream or downstream temperatures and pressures, if desired. Adding to its customizability, the Calculated Packed Volume based output numbers can be modified by using the Volume Calculation Multiplier and existing objects can be used for gas quality as well as RTUs.

LinePack offers a watchdog for each calculation made in addition to the surveillance of the overall program. The calculation rate is selected by the user ranging from every 0.1 seconds to once a day, and calculations can also be independently disabled if needed.

Included in the LinePack product are sample templates and objects, including calculation setup sample, manually entered gas quality object and manually entered RTU values object.

  • Errors and debugging messages are logged to the windows application event log.
  • LinePack offers static gas quality that may be shared with other LinePacks. Supply constant or manually changed values by having the gas quality reference point to any object that has the quality values supplied. Both live and static gas quality values are supported.
  • Both upstream and downstream pressures/temperatures are configured as independent points.

Pipe segment volume can be specified as pipe dimensions or entered manually. Packed volume can be calculated at a maximum and/or minimum pressure if desired.

ClearSCADA Integration

  • Data is obtained directly from the SCADA Expert ClearSCADA Database and has little impact on SCADA Expert ClearSCADA performance. Configuration uses point-and-click selections based on the current SCADA Expert ClearSCADA configuration.
  • Calculation results are stored and written back to objects in the SCADA Expert ClearSCADA database. Can be installed on backup machines and will automatically switch when the SCADA Expert ClearSCADA primary machine is changed.
  • SCADA Expert ClearSCADA redundancy keeps primary and backup LinePack applications synchronized. Automatically recognizes and adds new LinePack objects as they are added to SCADA Expert ClearSCADA.
