Solutions that identify cost savingsand increase data reliability>Reduce dataoverlapby up to 70%Ampla’s Plant MetalAccounting solution is partof its broader operationsmanagement offering.By combining the twosolutions, around 70%of the data required formetal accounting reportingis collected by theoperations managementfunction. This deliverssignificant cost savings,reduces software integrationand increases data reliability.>Ampla’sPlant MetalAccountingsolution isbased on:• Data Management• Measuring SaleableProduct• Metal Balancing• ReportingAmpla’s solution has been designed to address growing requirements fortransparency, auditability, accuracy and timeliness of production data in themetals and minerals industry.Ampla’s Plant Metal Accounting solution focuses on both the metal and masscontent, by collecting analytical data to meet requirements for Metallurgists,Operations, IT and Executive Officers.Ampla’s explicit process model provides functionality to collect productioninputs and outputs across the entire minerals and metals process. Usingstandard functionality, Ampla collects production and quality data at all stagesfrom crushing, grinding, flotation, leaching, smelting and refining.Whilst concentrating on the quality and grade of the metal content, as well asstockpiled inventory and work-in-progress, Ampla provides a range of datathat can be used for regulatory compliance and financial reporting.Ampla’s strength in security and auditing means the quality of data producedis credible, transparent, validated and auditable.Ampla’s Plant Metal Accounting reports are used for reconciliation andfinancial reporting requirements. Ampla delivers such data and reports toERP and other systems using standard connectivity options. Ampla’s masterdata synchronisation functionality also ensures data quality, by delivering clearand defined naming conventions across multiple applications.Data Management:The quality of data is paramount to metal accounting reporting, which is whyAmpla collects its data in an efficient, secure and reliable way. Production data(used for mass measurement) and laboratory data (for example, analyses) iscollected and integrated into a single user interface. Using its native connectorarchitecture, Ampla acquires data from various plant systems such as SCADA,Plant Historians, LIMS systems or other third-party databases.Measuring Saleable ProductBuilding upon AMIRA p754’s principles of a “Check in-Check out System”(where all streams, into and out of the process, are measured, sampled andanalysed), Ampla automatically and accurately establishes the mass of thematerial or component present at a specific time; and the mass flow of thatcomponent over a defined time period.Ampla then breaks down the measurement of materials into two components:òòIts mass, Ampla automatically captures data from its Inventoryfunctionality which allows for manual adjustments, stock takes, transientinventory and long-term process inventories;Its metal content, by using the Quality functionality, Ampla automaticallycaptures data from in-line analysers and laboratory information systems.It also caters for default values, partial analysis and re-analysis.

Metal BalancingWith a requirement to produce metal accounting to an “accountingstandard” there is a need to apply accuracy, integrity, security and auditability on the information relatingto the flow and transfer of materials and their contained metals.Ampla achieves this requirement by ensuring all source data is traceable and changes to data must beauthorised and recorded. Ampla’s role-based security focuses on defined roles and permissions toallow the right people, the right access, to the right data.ReportingAfter collecting all the required mass and metaldata, Ampla’s reporting functionality generatesstandard reports over various time frames andaccounting periods.As not all data is final and is likely to change,Ampla receives updated data from the laboratorysystem and makes the required adjustments,keeping a history of all changes. It never deletesthe data, so it is possible to review all values thata sample ever had.Ampla’s Plant Metal Accounting Solution wasdesigned to handle the month-end reportingprocess, including managing provisional and finaldata. Ampla locks data at the end of the reportingperiod. Any changes that occur after such point,appear in the next accounting period as carry-overadjustments. Operators and users can still viewthe most up-to-date data.Ampla reports deliver a summary of informationof material, broken down into saleable product, atthe end of the last accounting period and covers:ReconciliationòOpening BalanceWithin the process there will be uncertaintieswith measurements, samplings and analytics.Ampla manages the differences, between the netinput and output of the process, by treating theimbalance as an unaccounted gain or loss.To manage the imbalances, Ampla providesboth manual and automatic reconciliation. Forautomatic reconciliation, performing adjustmentson a mathematical exact balance, Amplaseamlessly integrates with specialist third-partyvendors who perform the statistical analysis fromthe raw measurements Ampla provides. In return,Ampla receives the corrected values.Manual adjustments can only be made by thosegranted access using Ampla’s security model.òòòInputsOutputsClosing BalanceThe reports highlight inconsistencies andproblem areas in the reported data and includestonnage and analysis figures for all Plant MetalAccounting streams. It also reports comparisonof performance figures against key performanceindicators and variance from the operating budgetor business plan.In addition to accounting requirements, the reportscontain information used for diagnosing plantoperating problems and for future productionplanning and project evaluation.Schneider Electric Industries S.A.SHead Office35 rue Joseph Monier92500 Rueil-Malmaisonwww.schneider-electric.comRef.
