3.4 FlexConn Modules

3.4.1 General

One of the main characteristics of the FlexConn architecture is the
placement flexibility of the FlexConn modules. The backbone of this
concept is the serial Control Area Network (CAN) bus to which each
FlexConn module connects.
CAN-HMI-MSC
FlexConn CAN bus concept
Each FlexConn module has one or more specific functions as follows:
A sensor function - Measures or calculates a process value, or

obtains a process value from a connected external instrument.
An application function - Controls the high-level operation of a

device. For example, stream control, flow control, or device control.
An Input/Output (I/O) function - Controls digital output or reads digital

input from instruments around the loading framework.
A communication function - Ensures the communication with a

communication interface unit or with a DCS, SCADA, tank inventory,
or another terminal automation system.
A display function - Ensures communication with the module(s)

through an HMI.
