3.3 Entities
Information exchange between the various FlexConn modules takes
place
by means of the so-called entities.
An entity represents a unique information association within the
FlexConn architecture. This information may consist of measuring data,
status data, commissioning parameters, diagnostics data, or
commands.
In addition to information exchange between FlexConn modules,
entities are used for data presentation on the SmartView display, and for
the communication between the Engauge service tool and the
SmartRadar FlexLine.
The entities are represented by a textual description, for example,
“Reset”, “Tank bottom”, “Health”, or “Baudrate”.
The entities’ structure is related to:
 general status information;
 the generic FlexConn part;
 the function-specific FlexConn part.
3.3.1 Status Entities
The “Health” and “Commissioned” entities give information about the
general FlexConn module status and the functions implemented on this
module.
3.3.1.1 Health Entity
The “Health” entity reflects the condition of the entire module, each
single module function, and the calculated or measured value of a
sensor function.
The “Health” entity structure is defined by following items:
1. status
2. status category
3. status code
The status field gives high-level information:
 good
 uncertain
 bad
Residing one level below, the status category informs about the general
reason why the status is good, uncertain, or bad.
