954 SmartServo FlexLine
As an alternative function, the FCI-HT board also allows the connection
of up to 5 generic HART sensors operating in multi-drop digital mode or
one generic HART sensor operating in analog mode.
In the multi-drop digital mode situation, one or two of the generic HART
sensors can be [P1 Pressure] or [P3 Pressure], providing product pressure
and Vapour pressure respectively, but no HIMS density calculation will
be available.
The HART sensors and HIMS density measurement are allocated to a
function number in the FCI-HT software. See table below.
FlexConn Function Device Type
Function 1
[P1 Pressure]
Function 2
[P3 Pressure]
Function 3
[Distance]
Function 4
[Temperature]
Function 5
[Pressure]
Function 6
[Density]
Function 7
[Other]
Function 8
[HIMS Density]
Table 7-1 FlexConn function allocation
Function 1 is exclusively reserved for P1 pressure, Function 2 is
exclusively reserved for P3 pressure, and Function 8 is exclusively
reserved for HIMS density calculation.
Only one of each type of HART device can be allocated to a function.
Therefore, this limits the number of HART devices of each type that can
be fitted.
Example 1
4 HART pressure devices and 1 temperature device can be connected.
 P1 pressure device allocated to Function 1
 P3 pressure device allocated to Function 2
 one pressure device allocated to Function 5
 one pressure device allocated to Function 7
 the temperature device allocated to Function 4
