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
