CAUTION
The products described in this document are NOT designed for nuclear-qualified applications.
Using non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause inaccurate
readings.
For information on Rosemount nuclear-qualified products, contact your local Emerson Sales Representative.
WARNING
Explosions can result in death or serious injury.
Do not remove the transmitter covers in explosive environments when the circuit is live.
Fully engage both transmitter covers to meet explosion-proof requirements.
Before connecting a communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance
with intrinsically safe or non-incendive field wiring practices.
Verify the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
Install and tighten all four flange bolts before applying pressure.
Do not attempt to loosen or remove flange bolts while the transmitter is in service.
Replacement equipment or spare parts not approved by Emerson or use as spare parts could reduce the pressure retaining
capabilities of the transmitter and may render the instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
Improper assembly of manifolds to traditional flange can damage SuperModule™ Platform.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not contact
sensor module housing.
2
WARNING
SuperModule and electronics housing must have equivalent approval labeling in order to maintain hazardous location
approvals.
When upgrading, verify SuperModule and electronics housing certifications are equivalent. Differences in temperature class
ratings may exist, in which case the complete assembly takes the lowest of the individual component temperature classes (for
example, a T4/T5 rated electronics housing assembled to a T4 rated SuperModule is a T4 rated transmitter.)
Severe changes in the electrical loop may inhibit HART® Communication or the ability to reach alarm values. Therefore, Emerson
cannot absolutely warrant or guarantee that the correct failure alarm level (HIGH or LOW) can be read by the host system at the
time of annunciation.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could
be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access
by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

2.5 General block information
2.5.1 Modes
The Resource, Transducer, and all function blocks in the device have modes of operation.
These modes govern the operation of the block. Every block supports both automatic
(AUTO) and out of service (OOS) modes. Other modes may also be supported.
Changing modes
To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a
short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the
block is operating properly.
Permitted modes
It is possible to prevent unauthorized changes to the operating mode of a block. To do
this, configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is
recommended to always select OOS as one of the permitted modes.
Types of modes
For the procedures described in this manual, it will be helpful to understand the following
modes:
AUTO
Out of
Service
(OOS)
MAN
Other types
of modes
Note
When an upstream block is set to OOS, this will impact the output status of all
downstream blocks. The figure below depicts the hierarchy of blocks:
The functions performed by the block will execute. If the block has any
outputs, these will continue to update. This is typically the normal
operating mode.
The functions performed by the block will not execute. If the block has any
outputs, these will typically not update and the status of any values passed
to downstream blocks will be BAD. To make some changes to the
configuration of the block, change the mode of the block to OOS. When
the changes are complete, change the mode back to AUTO.
In this mode, variables that are passed out of the block can be manually
set for testing or override purposes.
Other types of modes are Cas, RCas, ROut, IMan and LO. Some of these
may be supported by different function blocks in the transmitter.
2.5.2
14 Emerson.com/Rosemount
Block instantiation
The transmitter supports the use of Function Block instantiation. When a device supports
block instantiation, the number of blocks and block types can be defined to match specific
Reference Manual Configuration
00809-0200-4801 February 2021
application needs.The number of blocks that can be instantiated is only limited by the
amount of memory within the device and the block types that are supported by the
device. Instantiation does not apply to standard device blocks like the Resource, Sensor
Transducer, LCD display Transducer, and Advanced Diagnostics.
By reading the parameter FREE_SPACE in the Resource block you can determine how
many blocks you can instantiate. Each block instantiated takes up 4.5573 percent of the
FREE_SPACE.
Block instantiation is done by the host control system or configuration tool, but not all
hosts are required to implement this functionality. Refer to the specific host or
configuration tool manual for more information.
2.5.3 Simulation
Simulation is the functionality of the AI Block. To support testing, either change the mode
of the block to manual and adjust the output value or enable simulation through the
configuration tool and manually enter a value for the measurement value and its status
(this single value will apply to all outputs). If electing to change the mode of the block to
manual, first set the ENABLE jumper on the field device.
With simulation enabled, the actual measurement value has no impact on the OUT value
or the status. The OUT values will all have the same value as determined by the simulate
value.
2.6 Resource block
2.6.1 FEATURES and FEATURES_SEL
The FEATURES parameter is read only and defines which host accessible features are
supported by the transmitter. See the Specifications section of the Rosemount 3051S
Product Data Sheet for the complete list.
Use FEATURES_SEL to turn on any of the supported features that are found in the
FEATURES parameter.
UNICODE
All configurable string variables in the transmitter, except tag names, are octet strings.
You may use either ASCII or Unicode. If the configuration device is generating Unicode
octet strings, you must set the Unicode option bit.
REPORTS
The transmitter supports alert reports. You must set the Reports option bit in the features
bit string to use this feature. If it is not set, the host must poll for alerts. If this bit is set, the
transmitter will actively report alerts.
Emerson.com/Rosemount 15
Configuration Reference Manual
February 2021 00809-0200-4801
SOFT W LOCK and HARD W LOCK
Inputs to the security and write lock functions include the hardware security switch, the
hardware and software write lock bits of the FEATURE_SEL parameter, and the
WRITE_LOCK parameter.
The WRITE_LOCK parameter prevents modification of parameters within the device
except to clear the WRITE_LOCK parameter. During this time, the block will function
normally, updating inputs and outputs and executing algorithms. When the condition is
cleared, an alert is generated with a priority that corresponds to the WRITE_PRI
parameter.
The FEATURE_SEL parameter enables you to select any one of the following: a hardware
write lock, a software write lock, or no write lock capability. To enable the hardware
security function, enable the HARD W LOCK bit in the parameter. When this bit has been
enabled, the WRITE_LOCK parameter becomes read only and reflects the state of the
hardware switch. In order to enable the software write lock, place the hardware write lock
switch in the unlocked position. Then set the SOFT W LOCK bit in the FEATURE_SEL
parameter. Once this bit is set, you may set the WRITE_LOCK parameter to Locked or Not
Locked. Once you have set the WRITE_LOCK parameter to Locked with either the software
or the hardware lock, all user requested writes will be rejected.
2.6.2
2.6.3
MAX_NOTIFY
The MAX_NOTIFY parameter value of seven is the maximum number of alert reports the
resource can have sent without getting a confirmation from the host, corresponding to
the amount of buffer space available for alert messages. You can set the number lower, to
control alert flooding, by adjusting the LIM_NOTIFY parameter value. If LIM_NOTIFY is set
to zero, then no alerts are reported.
Alerts/alarms
The transmitter annunciates alerts as either Plantweb™ or NE107 Status Signals. All alerts
are configured, masked, and mapped as NE 107 Status Signals. If the control host is
DeltaV™ version 11.5 or older, alerts are automatically annunciated as Plantweb Alerts. No
user configuration is needed for this conversion.
The alerts and recommended actions should be used in conjunction with Troubleshooting.
See FOUNDATION™ Fieldbus Block Information for more information on resource block
parameters.
The resource block acts as a coordinator for alerts. Depending on user configuration, each
device will have either three or four alert parameters. If Plantweb alerts are annunciated,
the three alert parameters will be: FAILED_ALARM, MAINT_ALARM, and ADVISE_ALARM. If
NE107 alerts are annunciated, the four alert parameters called status signals will be:
FD_FAIL_ACTIVE, FD_OFFSPEC_ACTIVE, FD_MAINT_ACTIVE, and FD_CHECK_ACTIVE.
Note
NE107 alerts and Plantweb alerts annunciate the same diagnostics and display the same
recommended actions. The only difference in the alerts reported is the parameters or
status signals used to annunciate the alert conditions. The default factory configuration
has NE107 alerts enabled.

Alerts processing within the device
Procedure
1. Diagnostics perform comprehensive checks and update status within the device.
These status conditions allow you to troubleshoot probable causes and take
corrective actions.
2. The status conditions are then mapped into four status signals that can be used for
annunciation on the segment to the host.
3. Before annunciation, a check is made to determine if you have masked any alert
parameters. Any masked parameters will not be annunciated to the host, but will be
visible using the device DD or DTM.
4. Unmasked alert conditions are annunciated by the appropriate status signal to the
host.
Plantweb™ Alerts and NE107 Alerts are both processed using the steps described above
and annunciate the same consolidated status parameters.

Alerts have priorities that determine if they occur and where and how they are
annunciated.
NE107 status signals and Plantweb™ alerts use the same priorities and annunciate the
same ways.

Alerts will not occur. If there is an existing alert and the priority is changed from a
number greater than zero to zero, it will clear. Active device diagnostics are still
shown within the Device Description even if the alert has been cleared.

The associated alert is not sent as a notification. If the priority is above 1, then the
alert must be reported.
2
Reserved for alerts that do not require the attention of a plant operator, e.g.
diagnostic and system alerts. Block alert, error alert, and update event have a fixed
priority of 2.
3-7
Increasing higher priorities - advisory alerts.

NE107 alerts overview
NE107 alert parameters
NE107 has four alert status signals. They are in order from highest to lowest priority:
18 Emerson.com/Rosemount
Reference Manual Configuration
00809-0200-4801 February 2021
1. FD_FAIL_ACTIVE
2. FD_OFFSPEC_ACTIVE
3. FD_MAINT_ACTIVE
4. FD_CHECK_ACTIVE
You can configure any of the eight alert conditions to annunciate as any of the four status
signals. You can also map individual alert conditions into multiple status signals.
Alert parameter definitions and factory defaults
Note
All eight alert conditions are factory assigned to appropriate status signals. Change the
parameter assignment of individual alert conditions only if needed.
Devices are shipped from the factory with all applicable alerts enabled. The factory default
alert conditions reported in each status signal are:
1. FD_FAIL_ACTIVE
a. Incompatible module
b. Sensor failure
c. Electronics failure
A FD_FAIL_ACTIVE status signal indicates a failure within a device that will make the
device or some part of the device non-operational. This implies that the process
variable may no longer be available and the device is in need of immediate repair.
2. FD_OFFSPEC_ACTIVE
a. Pressure out of limits
b. Sensor temperature out of limits
A FD_OFFSPEC_ACTIVE status signal indicates that the device is experiencing
pressure or temperature conditions that are outside the device operating range.
This implies that the process variable may no longer be accurate. It also implies that
if the condition is ignored the device will eventually fail.
3. FD_MAINT_ACTIVE
a. Display update failure
b. Variation change detected
A FD_MAINT_ACTIVE status signal indicates the device is still functioning but an
abnormal process or device condition exists. The device should be checked to
determine the type of abnormal condition and recommended actions to resolve it.
4. FD_CHECK_ACTIVE
a. Function check
A FD_CHECK_ACTIVE status signal indicates a transducer block is not in “Auto”
mode. This may be due to configuration or maintenance activities.
Emerson.com/Rosemount 19
Configuration Reference Manual
February 2021 00809-0200-4801
Mapping alert conditions
You can map any of the alert conditions into any of the NE107 status signals using the
following parameters.
1. FD_FAIL_MAP assigns a condition to FD_FAIL_ACTIVE.
2. FD_OFFSPEC_MAP assigns a condition to FD_OFFSPEC_ACTIVE.
3. FD_MAINT_MAP assigns a condition to FD_MAINT_ACTIVE.
4. FD_CHECK_MAP assigns a condition to FD_CHECK_ACTIVE.
Masking alert conditions
You can mask any combination of status signals. When a status signal is masked, it will not
be annunciated to the host system but will still be active in the device and viewable in the
device DD or DTM. The recommended action, FD_RECOMMEN_ACT will continue to show
the recommended action for the most severe condition or conditions detected as
determined by the status signal priority. This allows maintenance personnel to view and
correct device conditions without annunciating the conditions to operational staff. They
are masked using the following parameters:
1. FD_FAIL_MASK to mask FD_FAIL_ACTIVE status signals
2. FD_OFFSPEC_MASK to mask FD_OFFSPEC_ACTIVE status signals
3. FD_MAINT_MASK to mask FD_MAINT_ACTIVE status signals
4. FD_CHECK_MASK to mask FD_CHECK_ACTIVE status signals
If you configure a consolidated diagnostic condition to annunciate in multiple status signal
categories, it can be masked in one or several status signal categories, but left active and
annunciate in others. This provides significant flexibility but can lead to confusion when
responding to alerts. Generally alert conditions are assigned to only a single status signal.
Alert priorities
NE107 alerts can have any of 16 different condition priorities ranging from the lowest
priority of 0 to the highest priority of 15. This is done using the following parameters.
1. FD_FAIL_PRI to specify the priority of FD_FAIL_ACTIVE status signals
2. FD_OFFSPEC_PRI to specify the priority FD_OFFSPEC_ACTIVE status signals
3. FD_MAINT_PRI to specify the priority FD_MAINT_ACTIVE status signals
4. FD_CHECK_PRI to specify the priority FD_CHECK_ACTIVE status signals
Note
FOUNDATION™ Fieldbus standards require that NE 107 alert priority is set to zero for all status
signals at manufacturing. Zero priority behavior shows any active device diagnostics in the
DD or DTM, but alerts are not generated based on the diagnostic conditions or published
on the bus. An alert priority of two or higher is required for every status signal category
where status signals are to be published on the bus. Check with your host provider to
determine the alarm priorities assigned to each status signal category by your host.
Manual configuration may be required. DeltaV assigns a priority of two or higher. The

priority is based on status signal category. The status signal priority determines the
behavior of both real and simulated alerts.
2.6.4 Plantweb alerts overview
Alerts are generated, mapped, and masked as NE 107 Status Signals. If Plantweb™ alerts
are required the NE 107 Status Signals are automatically converted to Plantweb alerts for
annunciation and display. Plantweb alerts have three alert parameters. They are in order
from highest to lowest priority:
1. FAILED_ALM
2. MAINT_ALM
3. ADVISE_ALM
The eight alert conditions are factory configured to annunciate as one of the three specific
alert parameters.
Plantweb alert parameter conditions and factory defaults
Emerson ships devices from the factory with all applicable Plantweb™ alerts enabled. The
alert conditions reported in each parameter are:
1. FAILED_ALM
a. Incompatible module
b. Sensor failure
c. Electronics failure
A FAILED_ALM indicates a failure within a device that will make the device or some
part of the device non-operational. This implies that the process variable may no
longer be available and the device is in need of immediate repair.
2. MAINT_ALM
a. Pressure out of limits
b. Sensor temperature out of limits
A MAINT_ALM indicates that the device is experiencing pressure or temperature
conditions that are outside the device operating range. This implies that the
process variable may no longer be accurate. It also implies that if the condition is
ignored the device will eventually fail. The device should be checked to determine
the type of abnormal condition and recommended actions to resolve it.
3. ADVISE_ALM
a. Function check
b. Display update failure
c. Variation change detected
An ADVISE_ALM indicates a transducer block is not in Auto mode. This may be due to
configuration or maintenance activities. It can also indicate an abnormal process or device
condition exists. Check the device to determine the type of abnormal condition and
recommended actions to resolve it.

Plantweb alert priorities
Configure Plantweb™ alert priorities in DeltaV™. Plantweb alerts can have any of 16
different condition prioritiesl, ranging from the lowest priority of 0 to the highest priority
of 15. This is done using the following parameters.
1. FAILED_PRI to specify the priority of FAILED_ALM
2. MAINT_PRI to specify the priority of MAINT_ALM
3. ADVISE_PRI to specify the priority of ADVISE_ALM
Plantweb alert priority is configured using DeltaV and is not part of the DD functionality.
2.7 Analog input (AI) function block
2.7.1 Configure the AI block
Note
Always check and reconcile function block configuration (with the exception of resource
and transducer blocks) after commissioning the transmitter to the control host. You may
not save function block configuration, including AI blocks, made prior to device
commissioning in the control host to the control host database during the commissioning
process. In addition, the control host may download configuration changes to the
transmitter as part of the commissioning process.
Note
Typically, you make changes to the AI block configuration after the transmitter is
commissioned using the control host configuraiton software. Consult your host system
documentation to see if the AI block guided configuration method provided in the DD or
DTM should be used after the device has been commissioned.
Note
DeltaV™ users should only make final AI block configuration and AI block configuration
changes using the DeltaV Explorer.
A minimum of four parameters are required to configure the AI block. The parameters are
described below with example configurations shown at the end of this section.

Note
For DeltaV users, only make final AI block configuration and AI block configuration
changes using the DeltaV Explorer.
A minimum of four parameters are required to configure the AI Block. The parameters are
described below with example configurations shown at the end of this section.
CHANNEL
Select the channel that corresponds to the desired sensor measurement. The transmitter
measures both pressure (channel 1) and sensor temperature (channel 2).
Table 2-1: I/O Channel Definitions
Channel number Channel description
1 Pressure in AI.XD_SCALE units
2 Sensor temperature in AI.XD_SCALE units
12 Mean
13 Standard deviation
Note
Channels 12-13 are only available when you order the Advanced Diagnostic Block is
licensed.
L_TYPE
The L_TYPE parameter defines the relationship of the sensor measurement (pressure or
sensor temperature) to the desired output of the AI Block (e.g. pressure, level, flow, etc.).
The relationship can be direct, indirect, or indirect square root.
Direct
Select direct when the desired output will be the same as the sensor measurement
(pressure or sensor temperature).
Indirect
Select indirect when the desired output is a calculated measurement based on the sensor
measurement (e.g. a pressure measurement is made to determine level in a tank). The
relationship between the sensor measurement and the calculated measurement will be
linear.
Indirect square root
Select indirect square root when the desired output is an inferred measurement based on
the sensor measurement and the relationship between the sensor measurement and the
inferred measurement is square root (e.g. flow).

XD_SCALE and OUT_SCALE
The XD_SCALE and OUT_SCALE each include three parameters: 0%, 100%, and
engineering units. Set these based on the L_TYPE:
L_TYPE is direct
When the desired output is the measured variable, set the XD_SCALE to the
Primary_Value_Range. This is found in the Sensor Transducer Block. Set OUT_SCALE to
match XD_SCALE.
L_TYPE is indirect
When an inferred measurement is made based on the sensor measurement, set the
XD_SCALE to represent the operating range that the sensor will see in the process.
Determine the inferred measurement values that correspond to the XD_SCALE 0 and
100% points and set these for the OUT_SCALE.
L_TYPE is indirect square root
When an inferred measurement is made based on the sensor measurement AND the
relationship between the inferred measurement and sensor measurement is square root,
set the XD_SCALE to represent the operating range that the sensor will see in the process.
Determine the inferred measurement values that correspond to the XD_SCALE 0 and
100% points and set these for the OUT_SCALE:

Filtering
The filtering feature changes the response time of the device to smooth variations in
output readings caused by rapid changes in input. Adjust the filter time constant (in
seconds) using the PV_FTIME parameter. Set the filter time constant to zero to disable the
filter feature.

Low cutoff
When the converted input value is below the limit specified by the LOW_CUT parameter,
and the low cutoff I/O option (IO_OPTS) is enabled (True), a value of zero is used for the
converted value (PV). This option is useful to eliminate false readings when the differential
pressure measurement is close to zero, and it may also be useful with zero-based
measurement devices such as flowmeters.
Note
Low cutoff is the only I/O option supported by the AI block. Set the I/O option in manual or
out of service mode only.
Process alarms
Process alarms are part of the process loop control strategy. They are configured in the
control host. Process alarm configuration is not included in the configuration menu tree.
See your control host documentation for information on configuration of process alarms.
Process Alarm detection is based on the OUT value. Configure the alarm limits of the
following standard alarms:
• High (HI_LIM)
Emerson.com/Rosemount 25
Configuration Reference Manual
February 2021 00809-0200-4801
• High high (HI_HI_LIM)
• Low (LO_LIM)
• Low low (LO_LO_LIM)
In order to avoid alarm chattering when the variable is oscillating around the alarm limit,
an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter.
The priority of each alarm is set in the following parameters:
• HI_PRI
• HI_HI_PRI
• LO_PRI
• LO_LO_PRI
Alarm priority
Alarms are grouped into five levels of priority:
Priority number Priority description
0 The alarm condition is not used.
1 An alarm condition with a priority of 1 is recognized by the system, but is not
reported to the operator.
2 An alarm condition with a priority of 2 is reported to the operator.
3–7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.
8–15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.
Status options
Status Options (STATUS_OPTS) supported by the AI block are shown below.
Propagate fault
forward
Uncertain if
limited
BAD if limited
Uncertain if Man
mode
If the status from the sensor is Bad, Device failure or Bad, Sensor
failure, propagate it to OUT without generating an alarm. The use of
these sub-status in OUT is determined by this option. Through this
option, the user may determine whether alarming (sending of an
alert) will be done by the block or propagated downstream for
alarming.
Set the output status of the Analog Input block to Uncertain if the
measured or calculated value is limited.
Set the output status to Bad if the sensor is violating a high or low
limit.
Set the output status of the Analog Input block to Uncertain if the
actual mode of the block is Man.
Note
The instrument must be in Out of Service mode to set the status option.

Advanced features
The AI function block provides added capability through the addition of the following
parameters:
ALARM_TYPE
ALARM_TYPE allows one or more of the process alarm conditions detected by the AI
function block to be used in setting its OUT_D parameter.
OUT_D
OUT_D is the discrete output of the AI function block based on the detection of process
alarm condition(s). This parameter may be linked to other function blocks that require a
discrete input based on the detected alarm condition.
2.8 LCD display transducer block
The LCD display meter connects directly to the FOUNDATION™ Fieldbus output board. The
meter indicates output and abbreviated diagnostic messages.
The meter features a four-line display and a 0-100 percent scaled bar graph.
• First line of five characters displays output description
• Second line of seven digits displays actual value
• Third line of six characters displays engineering units
• Fourth line displays Error when transmitter is in alarm
The LCD display meter can also display diagnostic messages.
Each parameter configured for display will appear on the LCD display for a brief period
before the next parameter is displayed. If the status of the parameter goes bad, the LCD
display will also cycle diagnostics following the displayed variable.

The LCD display transducer block can be configured to sequence four different process
variables as long as the parameters are sourced from a function block that is scheduled to
execute within the transmitter. If a function block is scheduled in the transmitter that links
a process variable from another device on the segment, that process variable can be
shown on the LCD display.
DISPLAY_PARAM_SEL
The DISPLAY_PARAM_SEL parameter specifies how many process variables will be
displayed. Select up to eight display parameters.
BLK_TAG_#
(1)
Enter the Block Tag of the function block that contains the parameter to be displayed.
BLK_TYPE_#
(1)
Enter the Block Type of the function block that contains the parameter to be displayed.
This parameter is generally selected via a drop-down menu with a list of possible function
block types. (e.g., Transducer, PID, AI, etc.)
PARAM_INDEX_#
(1)
The PARAM_INDEX_# parameter is generally selected via a drop-down menu with a list of
possible parameter names based upon what is available in the function block type
selected. Choose the parameter to be displayed.
CUSTOM_TAG_#
(1)
The CUSTOM_TAG_# is an optional user-specified tag identifier that can be configured to
be displayed with the parameter in place of the block tag. Enter a tag of up to five
characters.
UNITS_TYPE_#
(1)
The UNITS_TYPE_# parameter is generally selected via a drop-down menu with three
options: AUTO, CUSTOM, or NONE. Select AUTO only when the parameter to be displayed
is pressure, temperature, or percent. For other parameters, select CUSTOM and be sure to
configure the CUSTOM_UNITS_# parameter. Select NONE if the parameter is to be
displayed without associated units.
CUSTOM_UNITS_#
(1)
Specify custom units to be displayed with the parameter. Enter up to six characters. To
display Custom Units the UNITS_TYPE_# must be set to CUSTOM.
Displaying a variable from another device on the segment (example)
Any variable from a device on the network can be displayed on the LCD display but the
variable must be on a regularly scheduled communications cycle and the variable must be
linked to a block within the transmitter. A typical configuration to do this is to link the
output of the function block of the variable to one of the unused inputs of the Input
Selector Block.
(1) _# represents the specified parameter number.

2.8.2 Display bar graph
The LCD display is equipped with a bar graph along the top portion of the display screen.
The bar graph will display the percent of range of AI.OUT of the AI block configured for
Channel 1 (pressure) of the Sensor Transducer Block.
The bar graph on the LCD display can be enabled from the DISPLAY_PARAM_SEL
parameter in the LCD Block.
If no AI Block is found to be configured for Channel 1 the bar graph (including
annunciators) will remain blank. If more than one AI Block is found to be configured for the
Channel 1 the AI Block with the lowest OD index will be used to calculate the bar graph
value.
The following equation is used to calculate the percent of range of AI.OUT:
If the bar graph value calculation returns a value less than 0%, the LCD display will show a
bar graph value of 0 percent.
If the bar graph value calculation returns a value greater than 100 percent, then the LCD
display will show a bar graph value of 100 percent.
