1.1 The Filling Mass Transmitter from
Micro Motion
The Filling Mass Transmitter is designed for any process that requires high-speed highaccuracy filling or dosing.
The Filling Mass Transmitter, paired with a Coriolis sensor from Micro Motion, enables
mass-based measurement that is immune to variations in process fluid, temperature, or
pressure. Integrated-valve-control fills are implemented via high-precision discrete
outputs, for the fastest possible valve response. Automatic Overshoot Compensation
adjusts the system to minimize processing delays in valve control. Volume-based filling is
also available.
The Filling Mass Transmitter implements all of the advanced digital signal processing
algorithms, diagnostics, and features of the Micro Motion family of transmitters.

Fill types and fill options
Depending on your purchase option, the Filling Mass Transmitter supports either
integrated-valve-control fills or external-valve-control fills. For integrated-valve-control
installations, there are five types of integrated-valve-control fills and three fill options. Each
fill type and combination has different output requirements and is configured differently.
External valve control The transmitter measures flow and sends flow data to a host
over the frequency/pulse output. The host opens and closes
the valves and performs fill measurement. The transmitter is
unaware of the filling application.
Integrated valve control The host inititates the fill. The transmitter resets the fill total,
opens the valves, performs fill measurement, and closes the
valves.
Configuration and Use Manual 3
Introduction to filling with the Filling Mass Transmitter
Fill types and descriptions (continued)Table 1-1:
Transmitter model code Supported fill types Description
FMT*U
FMT*V
One-stage discrete The fill is controlled by a single discrete (ON/OFF) valve. The
valve opens completely when the fill begins, and closes completely when Fill Target is reached, or the fill is paused or ended.
Two-stage discrete The fill is controlled by two discrete valves: a primary valve and
a secondary valve. One valve must open at the beginning of
the fill; the other opens at a user-defined point. One valve
must stay open until the end of the fill; the other closes at a
user-defined point.
Timed The valve is open for the specified number of seconds.
Dual-fillhead Fill sequence:
1. Container #1 is moved into position.
2. Fillhead #1 begins filling Container #1, and Container #2 is
moved into position.
3. Fill #1 ends. Fillhead #2 begins filling Container #2. Container #1 is replaced by a new container.
Standard one-stage filling control is implemented for both fills:
The valve opens completely when the fill begins, and closes
completely when Fill Target is reached, or the fill is paused or
ended.
Dual-fillhead timed Fill sequence:
1. Container #1 is moved into position.
2. Fillhead #1 begins filling Container #1, and Container #2 is
moved into position.
3. Fill #1 ends. Fillhead #2 begins filling Container #2. Container #1 is replaced by a new container.
Timed control is implemented for both fills: Each valve is open
for the specified number of seconds.
Fill options and descriptionsTable 1-2:
Option Description Compatibility
Purge The Purge feature is used to control an auxiliary valve that
can be used for any non-filling purpose. For example, it can
be used for adding water or gas to the container after the
fill ends, or “padding.” Flow through the auxiliary valve is
not measured by the transmitter.
Pump The Pump feature is used to increase pressure during the
fill by starting an upstream pump just before the fill begins.
Automatic Overshoot Compensation (AOC)
Automatic Overshoot Compensation (AOC) is used to adjust fill timing to compensate for the time required to
transmit the valve close command or for the valve to close
completely.
Compatible with:
• One-stage discrete fills
• Two-stage discrete fills
• Timed fills
Compatible with:
• One-stage discrete fills
Compatible with:
• One-stage discrete fills
• Two-stage discrete fills

2 Quick start using ProLink II
Topics covered in this chapter:
Power up the transmitter
•
Check flowmeter status
•
Connect from ProLink II to the transmitter
•
Complete the configuration and commissioning process
•
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1. Follow appropriate procedures to ensure that a new device on the network does not
interfere with existing measurement and control loops.
2. Ensure that the cables are connected to the transmitter, as described in Micro Motion
Filling Mass Transmitters: Installation Manual .
3. Ensure that all transmitter and sensor covers and seals are closed.
Quick start using ProLink II
2.2
CAUTION!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.
4. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period,
Alarm 009 is active. The diagnostic routines should complete in approximately
30 seconds.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics
can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial
startup, or if power is been off long enough to allow components to reach ambient
temperature, allow the electronics to warm up for approximately 10 minutes before
relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.
Check flowmeter status
Check the flowmeter for any error conditions that require user action or that affect
measurement accuracy.
Configuration and Use Manual 7
Quick start using ProLink II
1. Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and
checks for error conditions. During the power-up sequence, Alarm A009 is active.
This alarm should clear automatically when the power-up sequence is complete.
2. Connect to the transmitter and check for active alarms.
Postrequisites
For information on viewing the list of active alarms, see Section 14.3.

8. When you have finished testing or tuning, disable sensor simulation.
Sensor simulation
Sensor simulation allows you to test the system or tune the loop without having to create
the test conditions in your process. When sensor simulation is enabled, the transmitter
reports the simulated values for mass flow, density, and temperature, and takes all
appropriate actions. For example, the transmitter might apply a cutoff, activate an event,
or post an alarm.
When sensor simulation is enabled, the simulated values are stored in the same memory
locations used for process data from the sensor. The simulated values are then used
throughout transmitter functioning. For example, sensor simulation will affect:
• All mass flow rate, temperature, and density values shown on the display or
reported via outputs or digital communications
• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and
volume inventories
• All mass, temperature, density, or volume values logged to Data Logger
2.4.2
Sensor simulation does not affect any diagnostic values.
Unlike actual mass flow rate and density values, the simulated values are not temperaturecompensated (adjusted for the effect of temperature on the sensor’s flow tubes).
Back up transmitter configuration
ProLink II and ProLink III provide a configuration upload/download function which allows
you to save configuration sets to your PC. This allows you to back up and restore your
transmitter configuration. It is also a convenient way to replicate a configuration across
multiple devices.

3.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1. Follow appropriate procedures to ensure that a new device on the network does not
interfere with existing measurement and control loops.
2. Ensure that the cables are connected to the transmitter, as described in Micro Motion
Filling Mass Transmitters: Installation Manual .
3. Ensure that all transmitter and sensor covers and seals are closed.
Quick start using Modbus
CAUTION!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.
4. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period,
Alarm 009 is active. The diagnostic routines should complete in approximately
30 seconds.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics
can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial
startup, or if power is been off long enough to allow components to reach ambient
temperature, allow the electronics to warm up for approximately 10 minutes before
relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.

Quick start using Modbus
3.2 Check flowmeter status
Check the flowmeter for any error conditions that require user action or that affect
measurement accuracy.
1. Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and
checks for error conditions. During the power-up sequence, Alarm A009 is active.
This alarm should clear automatically when the power-up sequence is complete.
2. Connect to the transmitter and check for active alarms.

4.2 Tips and tricks for configuring an integratedvalve-control fill
Before beginning your fill configuration, review the following:
• When you configure a fill, start with the factory-default settings. If you do not, the
transmitter may reject certain parameter combinations. See Section 4.2.1.
• The setting of Mass Flow Cutoff or Volume Flow Cutoff is important for fill accuracy. Be
sure to set the appropriate cutoff before running a fill, or before performing AOC
calibration. If you are using mass to measure the fill, see Section 11.2.3. If you are
using volume to measure the fill, see Section 11.3.2.
• The setting of Flow Direction controls how your fill total is measured. For integrated-
valve-control fills, see Effect of Flow Direction on the fill total.
• Fill measurement and operation may be affected by other transmitter parameters.
Review the general configuration information in Chapter 11, Chapter 12, and
Chapter 13.
• You can change the fill configuration or general transmitter configuration while a fill
is running. The configuration change will take effect after the fill ends.
4.2.1 Factory-default settings for basic fill parameters

Effects of Configure By on valve opening and closing
Configure By controls how the Open Primary, Open Secondary, Close Primary, and Close Secondary
values are configured and applied.
• When Configure By = % Target, the transmitter adds the configured Valve Open and
Valve Close values to 0%.
• When Configure By = Quantity, the transmitter adds the configured Valve Open values
to 0, and subtracts the configured Valve Close values from Fill Target.
Example: Configure By and valve open/close commands
Fill Target = 200 g. You want the primary valve to open at the beginning of the fill and close
at the end of the fill. You want the secondary valve to open after 10 g has been delivered,
and close after 190 g has been delivered. See Table 7-1 for the settings that will produce
this result.

Configure an integrated-valve-control fill using ProLink II
Option Description
Fixed
Overfill
Underfill
Tip
The Fixed option is typically not used. If you choose Fixed, the transmitter will operate like a
legacy batch controller. In typical applications, the other AOC options provide enhanced
accuracy and repeatability.
Restriction
The Fixed and Overfill options are not supported for dual-fillhead fills.
The valve will close at the point defined by Fill Target, minus the quantity specified
in Fixed Overshoot Comp. Use this option only if the "prewarn" value is already known.
Defines the direction used by the AOC algorithm to approach the target. The AOC
algorithm starts by estimating an overfill amount, and reduces the overfill in successive calibration fills.
Defines the direction used by the AOC algorithm to approach the target. The AOC
algorithm starts by estimating an underfill amount, and reduces the underfill in
successive calibration fills.
3. To implement Fixed AOC:
a. Disable Enable AOC.
b. Set AOC Algorithm to Fixed.
c. Set Fixed Overshoot Comp as desired.
The default value is 0, measured in process units.
The transmitter will close the valve when the current fill total is equal to Fill Target
minus the specified value (in process units).
4. To implement Overfill or Underfill:
a. Ensure that Enable AOC is enabled.
b. Set AOC Algorithm to either Overfill or Underfill.
c. Set AOC Window Length to the number of fills that will be used for AOC calibration.
The default is 10. The range is 2 to 32.
Tip
Micro Motion recommends using the default value unless you have special application
requirements.
Important
Do not change the values of AOC Change Limit or AOC Convergence Rate unless you are working
with Micro Motion customer service. These parameters are used to adjust the operation of
the AOC algorithm for special application requirements.
Configuration and Use Manual 41
Configure an integrated-valve-control fill using ProLink II
Postrequisites
If you set AOC Algorithm to Overfill or Underfill, you must perform an AOC calibration.
Perform AOC calibration using ProLink II
AOC calibration is used to calculate the AOC (Automatic Overshoot Compensation) value
from actual fill data. If you set AOC Algorithm to Overfill or Underfill, you must perform AOC
calibration.
There are two types of AOC calibration:
• Standard: The calibration is performed manually. The AOC coefficient is calculated
from fill data obtained during this calibration, and the same AOC coefficient is
applied until the calibration is repeated.
• Rolling: The calibration is performed continuously and automatically, and the AOC
coefficient is updated continuously based on fill data from the last set of fills.
Tip
For stable processes, Micro Motion recommends standard AOC calibration. If required, test both
methods and choose the method that yields the best results.
Perform standard AOC calibration
Standard AOC calibration is used to generate a constant AOC coefficient.
Prerequisites
AOC Window Length must be set appropriately. Micro Motion recommends using the default
value (10) unless you have special application requirements.
Mass Flow Cutoff or Volume Flow Cutoff must be set appropriately for your environment.
• If Flow Source is set to Mass Flow Rate, see Section 11.2.3.
• If Flow Source is set to Volume Flow Rate, see Section 11.3.2.
Your system must be ready to run fills, and you must know how to run fills.
ProLink II must be running and must be connected to the transmitter.
Procedure
1. Choose ProLink > Run Filler.
2. To calibrate the primary valve (all fill types):
a. Click Start AOC Cal.
b. Run two or more calibration fills, up to the number specified in AOC Window
Length.
42 Micro Motion® Filling Mass Transmitters with Modbus
Configure an integrated-valve-control fill using ProLink II
Note
You can run more calibration fills if you choose. The AOC coefficient is calculated from the
most recent fills.
Tip
In common use, the first few fills are slightly overfilled or underfilled due to factory-default
settings. As the calibration proceeds, the fills will converge on Fill Target.
c. When the fill totals are consistently satisfactory, click Save AOC Cal.
3. To calibrate the secondary valve (dual-fillhead fills):
a. Click Start Secondary AOC Cal.
b. Run two or more calibration fills, up to the number specified in AOC Window
Length.
The transmitter automatically runs fills through the secondary valve.
Note
You can run more calibration fills if you choose. The AOC coefficient is calculated from the
most recent fills.
Tip
In common use, the first few fills are slightly overfilled or underfilled due to factory-default
settings. As the calibration proceeds, the fills will converge on Fill Target.
c. When the fill totals are consistently satisfactory, click Save Secondary AOC Cal.
The current AOC coefficient is displayed in the Run Filler window. If you are running a dualfillhead fill, the Run Filler window displays the AOC coefficient for both the primary and the
secondary valve. These coefficients will be applied to fills as long as AOC is enabled.
Note
For two-stage discrete fills, the AOC value is applied to the valve that closes when the target is
reached. If the fill is configured to close both valves when the target is reached, the AOC value is
applied to both.
Tip
Micro Motion recommends repeating the AOC calibration if any of the following are true:
• Equipment has been replaced or adjusted.
• The flow rate has changed significantly.
• Fill accuracy is consistently lower than expected.
• Mass Flow Cutoff or Volume Flow Cutoff has been changed.
Configuration and Use Manual 43
Configure an integrated-valve-control fill using ProLink II
Set up rolling AOC calibration
Rolling AOC calibration is used to update the AOC coefficient continuously, based on fill
data from the last set of fills.
Prerequisites
AOC Window Length must be set appropriately. Micro Motion recommends using the default
value (10) unless you have special application requirements.
Your system must be ready to run fills, and you must know how to run fills.
ProLink II must be running and must be connected to the transmitter.
Procedure
1. Choose ProLink > Run Filler.
2. To calibrate the primary valve (all fill types), click Start AOC Cal. To calibrate the
secondary valve (dual-fillhead fills), click Start Secondary AOC Cal.
You can set up rolling AOC calibration for either valve or both valves.
3. Begin production filling.
5.2.2
The transmitter recalculates the AOC coefficient(s) after each fill, based on the last x fills
where x is the number specified in AOC Window Length. Current values are displayed in the
Run Filler window. If the configuration has changed or if process conditions have changed,
rolling AOC calibration will compensate for the change. However, the adjustment will take
place over several fills; that is, AOC will take a few fills to catch up.
Tip
At any time while AOC calibration is running, you can click Save AOC Cal or Save Secondary AOC Cal.
The current AOC coefficient will be saved and applied to all subsequent fills through the
corresponding valve. In other words, this action changes the AOC calibration method for that valve
from rolling to standard.
Configure the Purge feature using ProLink II
The Purge feature is used to control an auxiliary valve that can be used for any non-filling
purpose. For example, it can be used for adding water or gas to the container after the fill
ends, or “padding.” Flow through the auxiliary valve is not measured by the transmitter.
You can configure the Purge feature for automatic or manual purge control. If you choose
automatic control, the auxiliary valve is opened after each fill, and closed after the
configured purge time has elapsed.
Restriction
The Purge feature is not supported for dual-fillhead fills or dual-fillhead timed fills.
Prerequisites
The discrete outputs must be wired appropriately for your fill type and fill options.

Configuration and Use Manual 51
Configure an integrated-valve-control fill using ProLink II
• If a fill is running, it is ended.
In this example, the discrete input or event will never pause the fill because the End Fill
action takes priority.
Example: Incompatible assignments (not recommended)
Action assignments:
End Fill
•
Reset All Totals
•
Result of activation:
• If no fill is running, all totals, including the fill total, are reset.
• If a fill is running, it is ended and all totals, including the fill total, are reset.
The result of this combination is that the fill total is reset before the data can be retrieved.
5.4 Configure fill reporting using ProLink II
5.4.1
(optional)
You can configure the transmitter to report the fill ON/OFF state over Channel B (if it is
available), and percent of fill delivered over the mA output.
Configure Channel B to operate as a discrete output and report the fill ON/OFF state using ProLink II
If Channel B is available, you can use it to report whether or not a fill is running.
Prerequisites
ProLink II must be running and must be connected to the transmitter.
Channel B must be wired to operate as a discrete output.
Procedure
1. Choose ProLink > Configuration > Channel.
2. Set Channel B Type Assignment to Discrete Output.
3. Open the Discrete Output panel.
4. Set DO1 Assignment to Discrete Batch: Batching/Filling In Progress
5. Set DO1 Polarity as appropriate for your installation.

Tip
When the discrete output is used for fill reporting, Micro Motion recommends setting DO1
Fault Action to None.
The discrete output will be set to ON (valve open) if a fault
occurs.
The discrete output will be set to OFF (valve closed) if a fault
occurs.
No action will be taken if a fault occurs. The discrete output
will remain in the state it was in before the fault occurred.
5.4.2 Configure the mA output to report percentage of fill delivered using ProLink II
You can configure the mA output to report the percentage of Fill Target that has been
delivered. In a typical configuration, the current increases from 4 mA to 20 mA as the fill
total moves from 0% to 100%.
Prerequisites
ProLink II must be running and must be connected to the transmitter.
Procedure
1. Choose ProLink > Configuration > Analog Output.
2. Set Secondary Variable Is to Discrete Batch: Percent Fill.
3. Set Lower Range Value to the percentage of the fill to be represented by 4 mA.
4. Set Upper Range Value to the percentage of the fill to be represented by 20 mA.
5. Set AO Fault Action as desired.
If Lower Range Value is set to 0% and Upper Range Value is set to 100%: When the fill starts, the
mA output will generate a current of 4 mA (0% of Fill Target). The current will increase in
proportion to the fill total, up to a current of 20 mA (100% of Fill Target).
Configuration and Use Manual 53
Configure an integrated-valve-control fill using ProLink II
Note
If Flow Direction is set to Bidirectional or Negate Bidirectional, the fill total may decrease under certain flow
conditions. If this occurs, the current generated by the mA output will decrease proportionally.

6.1 Run an integrated-valve-control fill using
ProLink II
You can use ProLink II to start a fill, monitor the fill, pause and resume the fill, and end a fill.
Prerequisites
ProLink II must be running and must be connected to the transmitter.
Procedure
1. Choose ProLink > Run Filler.
2. (Optional) If desired, enter a different value for Fill Target (one-stage discrete fills,
two-stage discrete fills, or dual-fillhead fills), or for Target Time (timed fills or dualfillhead timed fills).
3. (Optional) If Automatic Overshoot Compensation (AOC) is enabled, you can enter a
different value for AOC Coeff.
Tip
In production use, Micro Motion recommends leaving AOC Coeff at the value determined
during AOC calibration. If you are running AOC calibration fills and you have an AOC Coeff
value available from a similar device, you can use that value as the "first approximation" value
on the current device. This may be helpful if you want to prevent or minimize spilling.
4. Click Begin Filling.
The fill total is reset automatically and the valve(s) are opened. The Filling In Progress
indicator should be On. If it is not, and the Start Not Okay indicator or the AOC Flow Rate
Too High indicator is On instead, troubleshoot the fill configuration and try again.
5. Monitor the fill using the Current Total and Percent Fill values and the Fill Status
indicators.
Configuration and Use Manual 55

A fill is currently being performed through the secondary
valve. This indicator is active even when the fill is paused. It
applies only to dual-fillhead fills.
The current fill has exceeded the current setting for Max Fill
Time. The fill is aborted.
The primary valve is open.
The secondary valve is open.
The pump is running.
A purge has been started, either manually or automatically.
An automatic purge cycle is in progress, and is currently in
the delay period between the completion of the fill and the
start of the purge.
The purge valve is open.
6. (Optional) Pause the fill if desired.
While the fill is paused, you can change the value of Current Target, end the fill
manually with End Filling, or restart the fill with Resume Filling. The fill resumes at the
current value of Current Total and Percent Fill.
Restriction
You cannot pause a timed fill or a dual-fillhead timed fill.
Important
For two-stage discrete fills, the effects of pausing and resuming the fill depend on the timing
of the valve open and valve close commands, and on the point at which the fill is paused.
7. (Optional) Use End Filling to end the fill manually if desired.
Once the fill is ended, it cannot be restarted.
56 Micro Motion® Filling Mass Transmitters with Modbus
Tip
In most cases, you should allow the fill to end automatically. End the fill manually only when
you are planning to discard the fill.
6.1.1 If the fill fails to start
If the fill fails to start, check the Start Not Okay and AOC Flow Rate Too High indicators.
If the Start Not Okay indicator is On, check the following:
• Ensure that filling is enabled.
• Ensure that the previous fill has been ended.
• Ensure that Fill Target or Target Time is set to a positive number.
• Ensure that all outputs have been assigned to the valve or pump appropriate for the
fill type and fill option.
• Ensure that there are no active fault conditions at the transmitter.
• For dual-fillhead fills and dual-fillhead timed fills, ensure that no fill is running on
either fillhead.
Fill operation using ProLink II
6.1.2
If the AOC Flow Rate Too High indicator is on, the last measured flow rate is too high to allow
the fill to start. In other words, the AOC coefficient, compensated for the flow rate,
specifies that the valve close command should be issued before the fill has begun. This can
happen if the flow rate has increased significantly since the AOC coefficient was calculated.
Micro Motion recommends the following recovery procedure:
1. Perform any setup that is required to perform AOC calibration.
2. In the Run Filler window, click Override Blocked Start.
3. Perform AOC calibration.
4. Return your system to production filling, using the new AOC coefficient.
If the fill did not run to completion
If your fill terminated abnormally, check the transmitter and the Max Fill Time Exceeded
indicator.
If a fault occurs during the fill, the transmitter automatically terminates the fill.
If the Max Fill Time Exceeded indicator is On, the fill did not reach its target before the
configured Max Fill Time. Consider the following possibilities or actions:
• Increase the flow rate of your process.
• Check for entrained gas (slug flow) in your process fluid.
• Check for blockages in the flow.
• Ensure that the valves are able to close at the expected speed.
• Set Max Fill Time to a higher value.
• Disable Max Fill Time by setting it to 0.
Configuration and Use Manual 57

6.1.3 Effects of Pause and Resume on two-stage discrete fills
For two-stage discrete fills, the effects of pausing and resuming the fill depend on where
the Pause and Resume actions occur in relation to the opening and closing of the primary
and secondary valves.

6.4 Monitor and analyze fill performance using ProLink II
You can collect detailed flow data for a single fill, and you can compare data across
multiple fills.
6.4.1 Collect detailed fill data for a single fill using ProLink II
When fill logging is enabled, detailed data for the most recent fill is stored on the
transmitter. You can retrieve it for analysis using digital communications. The detailed
data can be used for tuning or troubleshooting your production environment.
Restriction
Although you can use ProLink II to enable and disable fill logging, you cannot view the fill log with
ProLink II. To view the fill log, you must use a Modbus or PROFIBUS connection.
Prerequisites
ProLink II must be running and must be connected to the transmitter.
6.4.2
Procedure
1. Choose ProLink > Configuration > Filling.
2. Enable Enable Fill Logging.
3. Run a fill.
4. Disable Enable Fill Logging when you are finished with data collection.
The fill log contains data records from a single fill, from the beginning of the fill until
50 milliseconds after flow stops, or until the maximum log size is reached. Data records are
written every 10 milliseconds. Each data record contains the current value of Flow Source
(the process variable used to measure the fill). The fill log is limited to 1000 records, or
10 seconds of filling. When the maximum size is reached, logging stops but the data is
available on the transmitter until the next fill starts. The fill log is cleared each time a fill
starts.
Analyze fill performance using fill statistics and ProLink II
The transmitter automatically records a variety of data about each fill. This data is available
to assist you in tuning your system.
Prerequisites
ProLink II must be running and must be connected to the transmitter.
Procedure
1. Choose ProLink > Run Filler.
2. (Optional) Click Reset Fill Statistics to start your analysis with a fresh set of fill data.

The fill duration will be incremented until the transmitter detects that flow has
stopped, after valve closure.
The fill duration will be incremented until the transmitter sets the discrete output as required to close the valve.
10. Set Open Primary, Open Secondary, Close Primary, and Close Secondary as desired.
These values control the point in the fill at which the primary and secondary valves
open and close. They are configured either by quantity or by percent of the target,
as controlled by the Configure By parameter.
Either Open Primary or Open Secondary must be set to open at the beginning of the fill.
Both can open at the beginning of the fill if desired. If you set one to open later, the
other one is automatically reset to open at the beginning.
Either Close Primary or Close Secondary must be set to close at the end of the fill. Both
can close at the end of the fill if desired. If you set one to close earlier, the other one
is automatically reset to close at the end.

Effects of Configure By on valve opening and closing
Configure By controls how the Open Primary, Open Secondary, Close Primary, and Close Secondary
values are configured and applied.
• When Configure By = % Target, the transmitter adds the configured Valve Open and
Valve Close values to 0%.
• When Configure By = Quantity, the transmitter adds the configured Valve Open values
to 0, and subtracts the configured Valve Close values from Fill Target.
Example: Configure By and valve open/close commands
Fill Target = 200 g. You want the primary valve to open at the beginning of the fill and close
at the end of the fill. You want the secondary valve to open after 10 g has been delivered,
and close after 190 g has been delivered. See Table 7-1 for the settings that will produce
this result.

7.2 Configure fill options using Modbus
Depending on your fill type, you can configure and implement Automatic Overshoot
Compensation, the Purge feature, or the Pump feature.
7.2.1
Configure and implement Automatic Overshoot Compensation (AOC) using Modbus
Automatic Overshoot Compensation (AOC) is used to adjust fill timing to compensate for
the time required to transmit the valve close command or for the valve to close
completely.
Prerequisites
Before setting up AOC, ensure that all other fill parameters are correctly configured.
You must have a Modbus utility or tool that allows you to read and write to the transmitter,
and an active Modbus connection.
You must have the Modbus Interface Tool (MIT) installed on your PC.
Procedure
1. Choose the type of AOC that you want to implement.
Configuration and Use Manual 87
Configure an integrated-valve-control fill using Modbus
Option Description
Fixed
Overfill
Underfill
Tip
The Fixed option is typically not used. If you choose Fixed, the transmitter will operate like a
legacy batch controller. In typical applications, the other AOC options provide enhanced
accuracy and repeatability.
Restriction
The Fixed and Overfill options are not supported for dual-fillhead fills.
The valve will close at the point defined by Fill Target, minus the quantity specified
in Fixed Overshoot Comp. Use this option only if the "prewarn" value is already known.
Defines the direction used by the AOC algorithm to approach the target. The AOC
algorithm starts by estimating an overfill amount, and reduces the overfill in successive calibration fills.
Defines the direction used by the AOC algorithm to approach the target. The AOC
algorithm starts by estimating an underfill amount, and reduces the underfill in
successive calibration fills.
2. To implement Fixed AOC:
a. Disable Enable AOC.
b. Set AOC Algorithm to Fixed.
c. Set Fixed Overshoot Comp as desired.
The default value is 0, measured in process units.
The transmitter will close the valve when the current fill total is equal to Fill Target
minus the specified value (in process units).
3. To implement Overfill or Underfill:
a. Ensure that Enable AOC is enabled.
b. Set AOC Algorithm to either Overfill or Underfill.
c. Set AOC Window Length to the number of fills that will be used for AOC calibration.
The default is 10. The range is 2 to 32.
Tip
Micro Motion recommends using the default value unless you have special application
requirements.
Important
Do not change the values of AOC Change Limit or AOC Convergence Rate unless you are working
with Micro Motion customer service. These parameters are used to adjust the operation of
the AOC algorithm for special application requirements.

Register 1309 0 Sets AOC Algorithm to Overfill
Register 1310 10 Sets AOC Window Length to 10 fills
Value Description
Postrequisites
If you set AOC Algorithm to Overfill or Underfill, you must perform an AOC calibration.
Perform AOC calibration using Modbus
AOC calibration is used to calculate the AOC (Automatic Overshoot Compensation) value
from actual fill data. If you set AOC Algorithm to Overfill or Underfill, you must perform AOC
calibration.
There are two types of AOC calibration:
• Standard: The calibration is performed manually. The AOC coefficient is calculated
from fill data obtained during this calibration, and the same AOC coefficient is
applied until the calibration is repeated.
• Rolling: The calibration is performed continuously and automatically, and the AOC
coefficient is updated continuously based on fill data from the last set of fills.
Tip
For stable processes, Micro Motion recommends standard AOC calibration. If required, test both
methods and choose the method that yields the best results.
Perform standard AOC calibration
Standard AOC calibration is used to generate a constant AOC coefficient.
Configuration and Use Manual 89
Configure an integrated-valve-control fill using Modbus
Prerequisites
AOC Window Length must be set appropriately. Micro Motion recommends using the default
value (10) unless you have special application requirements.
Mass Flow Cutoff or Volume Flow Cutoff must be set appropriately for your environment.
• If Flow Source is set to Mass Flow Rate, see Section 11.2.3.
• If Flow Source is set to Volume Flow Rate, see Section 11.3.2.
Your system must be ready to run fills, and you must know how to run fills.
You must have a Modbus utility or tool that allows you to read and write to the transmitter,
and an active Modbus connection.
You must have the Modbus Interface Tool (MIT) installed on your PC.
Procedure
1. To calibrate the primary valve (all fill types):
a. Write 1 to Start AOC Cal (Coil 209).
b. Run two or more calibration fills, up to the number specified in AOC Window
Length.
Note
You can run more calibration fills if you choose. The AOC coefficient is calculated from the
most recent fills.
Tip
In common use, the first few fills are slightly overfilled or underfilled due to factory-default
settings. As the calibration proceeds, the fills will converge on Fill Target.
c. When the fill totals are consistently satisfactory, write 1 to Save AOC Cal (Coil
210).
2. To calibrate the secondary valve (dual-fillhead fills):
a. Write 1 to Start Secondary AOC Cal (Coil 342).
b. Run two or more calibration fills, up to the number specified in AOC Window
Length.
The transmitter automatically runs fills through the secondary valve.
Note
You can run more calibration fills if you choose. The AOC coefficient is calculated from the
most recent fills.
90 Micro Motion® Filling Mass Transmitters with Modbus
Configure an integrated-valve-control fill using Modbus
Tip
In common use, the first few fills are slightly overfilled or underfilled due to factory-default
settings. As the calibration proceeds, the fills will converge on Fill Target.
c. When the fill totals are consistently satisfactory, write 1 to Save Secondary AOC Cal
(Coil 343).
The current AOC coefficient is displayed in the Run Filler window. If you are running a dualfillhead fill, the Run Filler window displays the AOC coefficient for both the primary and the
secondary valve. These coefficients will be applied to fills as long as AOC is enabled.
Note
For two-stage discrete fills, the AOC value is applied to the valve that closes when the target is
reached. If the fill is configured to close both valves when the target is reached, the AOC value is
applied to both.
Tip
Micro Motion recommends repeating the AOC calibration if any of the following are true:
• Equipment has been replaced or adjusted.
• The flow rate has changed significantly.
• Fill accuracy is consistently lower than expected.
• Mass Flow Cutoff or Volume Flow Cutoff has been changed.
Set up rolling AOC calibration
Rolling AOC calibration is used to update the AOC coefficient continuously, based on fill
data from the last set of fills.
Prerequisites
AOC Window Length must be set appropriately. Micro Motion recommends using the default
value (10) unless you have special application requirements.
Your system must be ready to run fills, and you must know how to run fills.
You must have a Modbus utility or tool that allows you to read and write to the transmitter,
and an active Modbus connection.
You must have the Modbus Interface Tool (MIT) installed on your PC.
Procedure
1. To calibrate the primary valve (all fill types), write 1 to Start AOC Cal (Coil 209). To
calibrate the secondary valve (dual-fillhead fills), write 1 to Start Secondary AOC Cal
(Coil 342).
You can set up rolling AOC calibration for either valve or both valves.
2. Begin production filling.
Configuration and Use Manual 91
Configure an integrated-valve-control fill using Modbus
The transmitter recalculates the AOC coefficient(s) after each fill, based on the last x fills
where x is the number specified in AOC Window Length. Current values are displayed in the
Run Filler window. If the configuration has changed or if process conditions have changed,
rolling AOC calibration will compensate for the change. However, the adjustment will take
place over several fills; that is, AOC will take a few fills to catch up.
Tip
At any time while AOC calibration is running, you can write 1 to Save AOC Cal (Coil 210) or write 1 to
Save Secondary AOC Cal (Coil 343). The current AOC coefficient will be saved and applied to all
subsequent fills through the corresponding valve. In other words, this action changes the AOC
calibration method for that valve from rolling to standard.
7.2.2 Configure the Purge feature using Modbus
The Purge feature is used to control an auxiliary valve that can be used for any non-filling
purpose. For example, it can be used for adding water or gas to the container after the fill
ends, or “padding.” Flow through the auxiliary valve is not measured by the transmitter.
You can configure the Purge feature for automatic or manual purge control. If you choose
automatic control, the auxiliary valve is opened after each fill, and closed after the
configured purge time has elapsed.
Restriction
The Purge feature is not supported for dual-fillhead fills or dual-fillhead timed fills.
Prerequisites
The discrete outputs must be wired appropriately for your fill type and fill options.
You must have a Modbus utility or tool that allows you to read and write to the transmitter,
and an active Modbus connection.
You must have the Modbus Interface Tool (MIT) installed on your PC.
Procedure
1. Configure Channel B to operate as a discrete output:
a. Set Channel B Type Assignment to Discrete Output.
b. Set DO1 Assignment to Discrete Batch: Purge Valve.
c. Set DO1 Polarity as appropriate for your installation.
Ensure that the ON signal opens the valve and the OFF signal closes the valve.
