Figure 2 Hardware interface instruction
HART piezoresistance silicon pressure module set has four main interfaces:
Alarm setting（AL）and configuration protection setting（WP）hardware dial switch;
J5,HART bus power interface;
J3,silicon pressure sensor connection interface;
Constant current/pressure mode dial switch;
2.3 Failure warning and configuration protection dial switch
Dial switch with “AL” is for failure warning current setting and “WP” is for configuration protection
setting.

Failure warning setting
HART piezoresistance silicon pressure module set has self-diagnosis function. Once the failure is
tested, such as sensor open circuit, sensor short circuit or AD failure, the board set shall output alarm
current automatically. The alarm current methods depend on the failure alarm current DIP switch
setting of the communication board. When AL DIP switch at OFF position is high alarm, the alarm
current is ≥21.75mA. When AL DIP switch at ON position is low alarm, the alarm current is ≤3.7mA.
Configuration Protection Setting
HART piezoresistance silicon pressure module set provides configuration protection DIP switch
setting. When it is (DIP switch at ON position) configuration protection, the board set is not allowed to
do any device configuration operation modification. When it is (DIP switch at OFF position)
configuration protection, the board set is allowed to do device configuration operation modification.
2.4 Bus Power Interface
MS0110 HART piezoresistance silicon pressure module set power and bus share the same a pair of
cable and it is called bus cable. The specific fieldbus cable recommended by IEC61158-2 is
suggested.
Bus cable should not share the same wiring pipe or wiring slot with other devices, and it shall be
away from high-power devices. The bus ends shall be grounded.
There is HART bus power interface for the communication board of HART piezoresistance silicon
pressure module set, and it can be used directly. And there is a terminal board to protect
communication board, shown as Figure 2, to protect bus power interface.
Please refer to Section 7.1 “Basic Parameter” for HART bus power voltage and requested matching
resistance in serial.

HART silicon pressure module set supports constant voltage and constant current pressure sensor.
The connection for the two drive mode is as showed as figure 3. If pressure sensor internal doesn’t
have temperature measurement diode, silicon pressure module set will take A/D internal
temperature sensor for temperature compensation by default. Constant current and constant
pressure mode is controlled by dial switch. CC represents constant current and CV represents
constant pressure. Please refer to the figure below:

Section 3 Working principle
The principle of pressure measurement for Silicon pressure module set is based on silicon pressure
sensor, using advanced microcontroller and sensor digitization measuring technique, high accuracy
algorithm to ensure pressure signal’s high precision measurement. The communication interface of
intelligent instrument uses advanced HART technology.
Silicon pressure module set is the same on logical construction, consisting of two parts, namely
communication module ( including acquisition circuit) and LCD module. Please refer to figure 6.

3.1 Working principle instruction
Silicon pressure module set uses Piezoresistive silicon pressure sensor. When working, working
pressure make the isolation diaphragm skewed and transmit the pressure to resistance bridge
(semiconductor technology) via filling liquid. In this way, pressure-related bridge circuit output
pressure changes, which will be measured and further dealt.
Figure 7 Silicon pressure sensor schematic diagram
Communication module will not only be responsible for real-time collection pressure original AD
value, but also combination of AD vaule and calibration parameter for pressure value calculations,
which will pass on upper device via HART protocol. The communication module of HART silicon
pressure can also control D/A output by calculated pressure value, to realize the control of analog

Figure 11 Configuration Information
Damp: range 0~32s
Unit: PV unit modification affects variables related to unit,
such as the upper or lower limit for the range or for the sensor. When you modify the unit, you can’t
modify upper or lower limit for the primary variable range, instead, you should modify them
separately.
The unit can be set as:inH2O, inHg, ftH2O, mmH2O, mmHg, psi, bar, mbar, g/cm2, kg/cm2, Pa,
kPa, MPa, torr, atm, inH2O@4degC, mmH2O@4degC。
Upper limit of the range: Corresponding to PV value of 20mA output current.
Lower limit of the range: Corresponding to PV value of 4mA output current.
You should press “Apply” to download it into device after the modification.
Set “upper limit of range” with present value: Set the PV as the upper limit of primary variable
range, and keep the lower limit of range the same as previously.
Set “lower limit of range” with present value: Set the PV as the lower limit of primary variable range,
it may probably modify upper limit at the same time.
Set “primary variable zero point” with present value: Set the PV as the primary variable zero point
when the pressure is 0.
4.2.4 Current Calibration
The steps of current calibration are shown as following:
1)Connect the loop, an ammeter with the 5 1/2 digit precision should be series-wounded in the
device output loop.

www.microcyber-fieldbus.com
11
2)Set device rolling address as 0, please refer to basic info configuration. If rolling address is 0
already, this step can be skipped.
3)Enter current calibration option TAB.
4)Select “current value” as 4mA, when the ammeter is stable, input the value in ammeter to
“adjustment value”, and then click “Apply”.
5)Select “current value” as 20mA, when the ammeter is stable, input the value in ammeter to
“adjustment value”, and then click “Apply”.
6)Select “current value” as blank, makes the device output current as PV value.
Notes: When the present output current value is high alarm current, the user cannot calibrate 4mA.
When the present output current value is low alarm current, the user cannot calibrate 20mA.
Configure Current Fixed Output
The user may set fixed current output in current calibration tab. Input the value of the current the
smart transmitter will be fixed on, to “fixed current value”, and click the button “enter/exit fixed current
mode” to enter or exit the mode of fixed current output. The text of the button can display “exit fixed
current mode” and “enter fixed current mode” in turn, to tell users what to do.
In the run of the HART smart transmitter, compare the value of the primary variable and range
upper/lower limit of the primary variable continuously. When the value of the primary variable
exceeds the range of the primary variable, the smart transmitter will output fixed current to indicate
that the value of the primary variable is exceeded. When it is over the upper limit, the smart
transmitter output fixed current 20.8mA;When it is less than the lower limit, output is 3.8mA.

Note: Calibration current and fixed current output functions are only in the moment when the polling
address is 0. It will be at absolute digital communication mode at other polling addresses, the failure
info is “Command Execution Failure”.
4.2.5 Variable Monitoring
The user is able to refresh all the dynamic variables of the selected device and display trend curve of
present device primary variable via variable monitoring tab. The present refreshing variables are: PV
value, current value, percentage and SV value.
