Entities
 
Information exchange between the various FlexConn modules takes 
place by means of the entities.
 
An entity represents a unique information association in the FlexConn 
architecture. This information may consist of measuring data, status 
data, commissioning parameters, diagnostics data, or commands.
 
In  addition  to  the  information  exchange  between  FlexConn  modules, 
entities are used for data presentation on the HART SmartView display, 
and for the communication between the Engauge service tool and the 
954 SmartServo FlexLine. 
The entities are represented by a textual description, for example, 
“Reset”, “Tank bottom”, “Health”, or “Baudrate”. 
The entities structure is related to the following: 
  General status information 
  Generic FlexConn part 
  Function-specific FlexConn part 
 Status 
Entities
 
The “Health” and “Commissioned” entities provide information about the 
general FlexConn module status and the functions implemented on this 
module. 
4.3.1.1  Health 
En
tity 
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
