954 SmartServo FlexLine
4.2 FlexConn Modules
One of the main characteristics of the 954 SmartServo FlexLine
architecture is its placement flexibility of the FlexConn modules. Any
types of modules can be added. Two identical modules can also be
placed in the 954 SmartServo FlexLine system.
Each FlexConn module has one or more function. 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 ensures 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 in the SmartLink system.
Each FlexConn module has a unique name, which is built according to
the following image.
