3.2 FlexConn Modules
One of the main characteristics of the SmartRadar FlexLine architecture
is its placement flexibility of the FlexConn modules. If desired, any types
of modules can be added at any locations. Even placement of 2
identical modules is possible within the SmartRadar FlexLine system.
Each FlexConn module has one or more functions. In general, this can
be a sensor function, a communication function, or a digital-interface
function.
A sensor function measures or calculates a process value, or it obtains
a process value from a connected external instrument.
A communication function takes care of the communication with a
communication interface unit or with a DCS, SCADA, tank inventory, or
another terminal automation system.
A digital-interface function controls digital output or reads digital input
from instruments around the storage tank.
NOTE: Some FlexConn PCBs are also used within the so-
called SmartLink system.
Each FlexConn module has a unique name, which is built up according
to the following outline:
FlexConn Module Name
XXX-YYY
prefix - suffix
specific name or function
M = positioned in SmartLink (safe zone)
I = positioned in gauge
or field instrument (hazardous zone)
C = C ommunication with generic devices
I = I nterface with dedicated equipment
H = connects to H ost instrumentation
F = connects to F ield instrumentation
T = T ransducer, typical gauge function
