DACM System topology

Instrument synthese

DACM-01 Hardware implementation

Component Type Definition

- Definition of the parameter set, later offered to the user(names, units, transfer characteristics, result selection,calibration constants etc.)

- Memory space allocation for basic data- Calculation rules and procedures for results- General result data format

Component properties

Configuration structure

Data structure

- Identification (names, codes etc.)- Possible states of the component type within the cycle (ON/OFF, set-points etc.)- Data and alert handling

Disconnects component functions from their hardware implementation!

Benefits for

Manufacturer:New components can be defined or derived by extensionComponents can be implemented to any hardware platformInstrument specific component sets possible (several types and numbers)Hardware independent configuration and operation software (PC)

User:full control over the whole instrument functionalitysimple re-configuration and extension without manufacturerGeneralised data base for generated results (from simple to very complex)

DACM Dual software concept

Simple configuration interface, administratorknows the structure of the instrument and theintention of the measurement procedure

DACM based instrument looks likea powerful, universal toolbox

Configuration Software

- Cycle Definition- Component Configuration- Calibration work / Testing

DACM based instrument looks likea simple, ready to use instrument

No knowledge about internal functions required

Operation Software

- Module Setup- Cycle Selection- Data Handling- Visualisation/Analysis
