Configuration
The SNE is configured by the System Controller (SYSCON) and periodically reports analysis
results. It can be interactively controlled for Real-Time decisions on operation scenarios. The
SNE software controls all sampling relating to its internal configuration and sensor setup.
Components
The major SNE software components are as follows:
● Data Manager
● Communications Manager
● Hardware Manager
● Computational Engine
Data Manager
The Data Manager maintains configuration data that controls hardware sequence of events
and controls what manipulation is performed on sampled data.
The Data Manager also provides results and status information to externally connected devices
via the Communication Manager. This data is organized as a set of Sensor Analyzer Module
(SAM) structures. The data represents the unit as a standard sensor to external host.
Communication Manager
The Communication Manager acts as a central point of control for communication links
attached to the Sensor Near Electronics (SNE). This allows Internal SNE software to function
regardless of which communication link is being used to communicate with the system.
Hardware Manager
The Hardware Manager provides scheduling and communication services for the hardware in
the analysis zone. These include devices such as the following:
● Detectors
● Sample valves
● Relays
● Pressure monitors and controllers
● Temperature monitors and controllers
● Flow control valves
Computational Engine
The Computational Engine takes acquired chromatography data and performs system
calculations. Most of these calculations are performed by functions contained in the EZChrom
method, which provides all peak identifications and integration and response factors.
