Note: If this is the initial startup, or if power has been off long enough to allow components to reach ambient temperature, the flowmeter is ready to receive process fluid approximately one minute after power-up. However, it may take up to ten minutes for the electronics in the flowmeter to reach thermal equilibrium. During this warm-up period, you may observe minor measurement instability or inaccuracy.
When the transmitter receives power, it will automatically perform diagnostic routines, and the module LED flashes red and green. When the flowmeter has completed its power-up sequence, the status LED will show a solid green. See Section 7.4 for information on LED behavior. If the status LED exhibits different behavior, an alarm condition is present. See Section 7.5.

4.4 Connecting to a Model 2400S DN transmitter

To connect to the Model 2400S DN transmitter using ProLink II, you must use a service port connection.

4.4.1 Connection options

The service port can be accessed via the service port clips or the IrDA port.
The service port clips have priority over the IrDA port:
If there is an active connection via the service port clips, access via the IrDA port is disabled.
If there is an active connection via the IrDA port and a connection attempt is made via the service port clips, the IrDA connection is terminated.
Additionally, access via the IrDA port may be disabled altogether. In this case, it is not available for connections at any time. By default, access via the IrDA port is disabled. See Section 8.10.6 for more information.

4.4.2 Service port connection parameters

The service port uses default connection parameters. Additionally, to minimize configuration requirements, the service port employs an auto-detection scheme when responding to connection requests. The service port will accept all connection requests within the limits described in Table 4-1. If you are connecting to the service port from another tool, ensure that configuration parameters are set within these limits.
Table 4 -1 Service port auto-detection limits
Parameter Option
Protocol Modbus ASCII or Modbus RTU

Using a DeviceNet Tool

5.1 Overview

A customer-supplied DeviceNet tool can be used to communicate with the Model 2400S DN transmitter. This chapter provides basic information on using a customer-supplied DeviceNet tool.
However, because there are a variety of DeviceNet tools available, this chapter does not provide detailed information for using any one tool. For detailed information on your DeviceNet tool, see the documentation supplied with the tool.

5.2 Connecting to the Model 2400S DN transmitter

To connect to the Model 2400S DN transmitter:
1. Default connection values for this transmitter are as follows:
DeviceNet node address =
•Baud rate = 125 kBaud
63
Required Configuration Optional ConfigurationUsing the TransmitterUsing a DeviceNet Tool
If required, use the digital communications hardware switches on the device to set the DeviceNet node address and baud rate for this transmitter. To do this, see Sections 8.10.1 and
8.10.2.
2. Connect to the network where the transmitter is installed.
3. Using the same methods that you use for other DeviceNet devices, establish a connection to the Model 2400S DN transmitter, using the appropriate node address and baud rate.

5.3 Using the DeviceNet device profile

All DeviceNet devices employ a device profile with an object-instance-attribute structure.
In general, process and configuration data is stored in attributes, and operational functions are performed by using services or setting attributes to specific values.
Two standard services are used to read or write single attributes:
The Get Single Attribute service (0x0E) performs an explicit read and returns a single value from the transmitter.
The Set Single Attribute service (0x10) performs an explicit write and writes a single value to the transmitter.
In this manual, these two services are referenced as the Get and Set services.
Other services are used to reset values to These services are identified by name and by service code (a hexadecimal label).
Input assemblies are used to publish multiple values to the DeviceNet bus. A summary of the input assemblies is provided in Table 7-2. Output assemblies can be used to read data from the DeviceNet bus or to perform totalizer and inventory control. Summaries of the output assemblies are provided in Tables 7-9 and 9-1.
0, start or stop calibrations, to acknowledge alarms, etc.
Configuration and Use Manual 21
Using a DeviceNet Tool
For complete documentation of the Model 2400S DN transmitter’s device profile, including input and output assemblies, see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.

5.4 Using a DeviceNet tool

Micro Motion supplies an Electronic Data Sheet (EDS) for the Model 2400S transmitter. The EDS file is named
MMI2400S-MassFlow.eds. The EDS presents the device profile in a format designed to
be read and interpreted by other devices.
DeviceNet tools fall into two basic categories:
Type A: Tools that use the EDS to build a unique user interface for the specific device
Type B: Tools that do not use the EDS, and instead rely on the user to supply the object-instance-attribute information required to interact with the device

5.4.1 Type A tools

If you are using a Type A tool:
1. Use your tool’s standard methods to read or import the supplied EDS into the network configuration tool (e.g., RSLinx).
2. Use your tool’s standard user interface to configure, view, and manage the transmitter.
3. If you want to perform a function that isn’t available through your tool, see the instructions for Type B tools.

5.4.2 Type B tools

If you are using a Type B tool, or if you want to access features that are not available through your tool’s user interface, you must reference the feature by class, instance, and attribute, use the appropriate service, and supply an attribute value if required. Depending on the attribute, the value may be a numeric or character value or a code. Values must be entered in the data type appropriate to the attribute.
For example:
To configure the mass flow cutoff, you must:
a. Specify the Analog Input Point class.
b. Specify the Mass Flow instance.
c. Specify the cutoff attribute.
d. Use the Set service to set the attribute value to the desired cutoff.
To read the mass flow process variable, you can use either of the following methods:
- Use the Get service to read the value of the corresponding attribute.
- Use one of the input assemblies that contains the mass flow process variable.
This manual provides class, instance, attribute, data type, and service information for most configuration parameters and for all procedures. Complete documentation of the Model 2400S DN transmitter’s device profile is provided in the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.

Required Transmitter Configuration

6.1 Overview

This chapter describes the configuration procedures that are usually required when a transmitter is installed for the first time.
The following procedures are discussed:
Characterizing the flowmeter – see Section 6.2
Configuring measurement units – see Section 6.3
This chapter provides basic flowcharts for each procedure. For more detailed flowcharts, see the flowcharts for your communication tool, provided in the appendices to this manual.
For optional transmitter configuration parameters and procedures, see Chapter 8.
Note: All ProLink II procedures provided in this chapter assume that you have established communication between ProLink II and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements. See Chapter 4 for more information.

Note: All DeviceNet tool procedures provided in this chapter assume that you have established communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements. See Chapter 5 for more information.

6.2 Characterizing the flowmeter

Characterizing the flowmeter adjusts the transmitter to compensate for the unique traits of the sensor it is paired with. The characterization parameters, or calibration factors, describe the sensor’s sensitivity to flow, density, and temperature.

6.2.1 When to characterize

If the transmitter and sensor were ordered together, then the flowmeter has already been characterized. You need to characterize the flowmeter only if the transmitter and sensor are being paired together for the first time.

6.2.2 Characterization parameters

The characterization parameters that must be configured depend on your flowmeter’s sensor type: “T-Series” or “Other” (also referred to as “Straight Tube” and “Curved Tube,” respectively), as listed in Table 6-1. The “Other” category includes all Micro Motion sensors except T-Series.
The characterization parameters are provided on the sensor tag. See Figure 6-1 for illustrations of sensor tags.

Two factors are used to define flow calibration:
The flow calibration factor, which is a 6-character string (five numbers and a decimal point)
The temperature coefficient for flow, which is a 4-character string (three numbers and a decimal point)
These values are concatenated on the sensor tag, but different labels are used for different sensors. As shown in Figure 6-1:
For T-Series sensors, the value is called the FCF value.
For other sensors, the value is called the Flow Cal value.

6.3 Configuring the measurement units

For each process variable, the transmitter must be configured to use the measurement unit appropriate to your application.
To configure measurement units for process variables, see the menu flowcharts in Figure 6-3. For details on measurement units for each process variable, see Sections 6.3.1 through 6.3.4.
The measurement units used for totalizers and inventories are assigned automatically, based on the measurement unit configured for the corresponding process variable. For example, if per hour) is configured for mass flow, the unit used for the mass flow totalizer and mass flow inventory is
kg (kilograms). DeviceNet codes used for the measurement units are listed in Tables C-12
through C-14.
Note: Pressure unit configuration is required only if you are using pressure compensation (see Section 9.2) or you are using the Gas Wizard and you need to change the pressure units (see Section 8.2).

6.3.5 Pressure units

The flowmeter does not measure pressure. You need to configure the pressure units if either of the following is true:
You will configure pressure compensation (see Section 9.2). In this case, configure the pressure unit to match the pressure unit used by the external pressure device.
Required Configuration Optional ConfigurationUsing the TransmitterUsing a DeviceNet Tool
You will use the Gas Wizard, you will enter a reference pressure value, and you need to change the pressure unit to match the reference pressure value (see Section 8.2).
If you do not know whether or not you will use pressure compensation or the Gas Wizard, you do not need to configure a pressure unit at this time. You can always configure the pressure unit later.
The default pressure measurement unit is
PSI. See Table 6-7 for a complete list of pressure
measurement units.

Using the Transmitter

7.1 Overview

This chapter describes how to use the transmitter in everyday operation. The following topics and procedures are discussed:
Recording process variables – see Section 7.2
Viewing process variables – see Section 7.3
Viewing transmitter status and alarms – see Section 7.5
Handling status alarms – see Section 7.6
Viewing and controlling the totalizers and inventories – see Section 7.7
Note: All ProLink II procedures provided in this chapter assume that you have established communication between ProLink II and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements. See Chapter 4 for more information.

Note: All DeviceNet tool procedures provided in this chapter assume that you have established communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements. See Chapter 5 for more information.

7.2 Recording process variables

Micro Motion suggests that you make a record of the process variables listed below, under normal operating conditions. This will help you recognize when the process variables are unusually high or low, and may help in fine-tuning transmitter configuration.
Record the following process variables:
Flow rate
Density
•Temperature
Tube frequency
Pickoff voltage
•Drive gain
To view these values, see Section 7.3. For information on using this information in troubleshooting, see Section 11.13.
Configuration and Use Manual 35
Using the Transmitter

7.3 Viewing process variables

Process variables include measurements such as mass flow rate, volume flow rate, mass total, volume total, temperature, and density.
You can view process variables with the display (if your transmitter has a display), ProLink II, or a DeviceNet tool.
Note: If the petroleum measurement application is enabled, two of the API process variables are averages: Batch Weighted Average Density and Batch Weighted Average Temperature. For both of these, the averages are calculated for the current totalizer period, i.e., since the last reset of the API volume totalizer.

7.3.1 With the display

By default, the display shows the mass flow rate, mass total, volume flow rate, volume total, temperature, density, and drive gain. If desired, you can configure the display to show other process variables. See Section 8.9.5.
The LCD panel reports the abbreviated name of the process variable (e.g., current value of that process variable, and the associated unit of measure (e.g., Appendix D for information on the codes and abbreviations used for display variables.
To view a process variable with the display:
If Auto Scroll is enabled, wait until the desired process variable appears on the LCD panel.
DENS for density), the
G/CM3). See
If Auto Scroll is not enabled,
Scroll until the name of the desired process variable either:
- Appears on the process variable line, or
- Begins to alternate with the units of measure
See Figure 3-2.
The display precision can be configured separately for each process variable (see Section 8.9.5). This affects only the value shown on the display, and does not affect the actual value as reported by the transmitter via digital communications.
Process variable values are displayed using either standard decimal notation or exponential notation:
Values smaller than 100,000,000 are displayed in decimal notation (e.g.,
Values greater than 100,000,000 are displayed using exponential notation (e.g.,
1234567.89).
1.000E08).
- If the value is less than the precision configured for that process variable, the value is displayed as
0 (i.e., there is no exponential notation for fractional numbers).
- If the value is too large to be displayed with the configured precision, the displayed precision is reduced (i.e., the decimal point is shifted to the right) as required so that the value can be displayed.

7.3.2 With ProLink II

The Process Variables window opens automatically when you first connect to the transmitter. This window displays current values for the standard process variables (mass, volume, density, temperature, external pressure, and external temperature).
To view the standard process variables with ProLink II, if you have closed the Process Variables window, click

7.3.3 With a DeviceNet tool

There are two methods that can be used to view process variables with a DeviceNet tool:
You can execute Gets to read the current values of individual process variables from the appropriate objects. Table 7-1 lists the most commonly used process variables, by class, instance, attribute, and data type. For more information, see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.
You can use the predefined input assemblies. The predefined input assemblies are summarized in Table 7-2. For more information, see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.

7.4 Using the LEDs

The user interface module provides three LEDs: a status LED, a module LED, and a network LED (see Figures 3-1 and 3-2).
For transmitters with a display, the LEDs can be viewed with the transmitter housing cover in place.
For transmitters without a display, the transmitter housing cover must be removed to view the LEDs (see Section 3.3).
For more information:
On using the module LED, see Section 7.4.1.
On using the network LED, see Section 7.4.2.
On using the status LED, see Section 7.5.1.

7.4.1 Using the module LED

The module LED indicates whether or not the transmitter has power and is operating properly. Table 7-3 lists the different states of the module LED, defines each state, and provides recommendations for correcting problem states.

7.5 Viewing transmitter status

You can view transmitter status using the status LED, ProLink II, or a DeviceNet tool. Depending on the method chosen, different information is displayed.

7.5.1 Using the status LED

The status LED shows transmitter status as described in Table 7-5. Note that the status LED does not report event status or alarm status for alarms with severity level set to Ignore (see Section 8.8).

7.5.3 Using a DeviceNet tool

Status information is located in the Diagnostics Object (0x66), Instance 1. This Object includes, among other data:
Alarm status (Attributes 12–17, Attributes 40–41)
Event status (Attribute 11)
Drive gain (Attribute 20)
Tube frequency (Attribute 21)
Left and right pickoff voltages (Attributes 23 and 24)
Use the Get service to read the required data. See Table C-7, or see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile for detailed information.

7.6 Handling status alarms

Specific process or flowmeter conditions cause status alarms. Each status alarm has an alarm code.
Status alarms are classified into three severity levels: Fault, Information, and Ignore. Severity level controls how the transmitter responds to the alarm condition.
Note: Some status alarms can be reclassified, i.e., configured for a different severity level. For information on configuring severity level, see Section 8.8.
Note: For detailed information on a specific status alarm, including possible causes and troubleshooting suggestions, see Table 11-2. Before troubleshooting status alarms, first acknowledge all alarms. This will remove inactive alarms from the list so that you can focus troubleshooting efforts on active alarms.
The transmitter maintains two status flags for each alarm:
The first status flag indicates “active” or “inactive.”
The second status flag indicates “acknowledged” or “unacknowledged.”
Configuration and Use Manual 43
Using the Transmitter
In addition, the transmitter maintains alarm history for the 50 most recent alarm occurrences. Alarm history includes:
The alarm code
The “alarm active” timestamp
The “alarm inactive” timestamp
The “alarm acknowledged” timestamp
When the transmitter detects an alarm condition, it checks the severity level of the specific alarm and performs the actions described in Table 7-6.
Table 7 -6 Transmitter responses to status alarms

When the transmitter detects that the alarm condition has cleared:
The first status flag is set to “inactive.”
Digital communications fault action is deactivated (Fault alarms only).
The “alarm inactive” record is written to alarm history (Fault and Informational alarms only).
The second status flag is not changed.
Operator action is required to return the second status flag to “acknowledged.” Alarm acknowledgment is not necessary. If the alarm is acknowledged, the “alarm acknowledged” record is written to alarm history.

7.6.1 Using the display

The display shows information only about active Fault or Informational alarms, based on alarm status bits. Ignore alarms are filtered out, and you cannot access alarm history via the display.
To view or acknowledge alarms using the display menus, see the flowchart in Figure 7-1.
If the transmitter does not have a display, or if operator access to the alarm menu is disabled (see Section 8.9.3), alarms can be viewed and acknowledged using ProLink II or a DeviceNet tool. Alarm acknowledgment is not required.
Additionally, the display may be configured to enable or disable the Ack All function. If disabled, the Ack All screen is not displayed and alarms must be acknowledged individually.

Configuration and Use Manual 45
Using the Transmitter
In the Status window:
Alarms are organized into three categories: Critical, Informational, and Operational. Each category is displayed on a separate panel.
If one or more alarms is active on a panel, the corresponding tab is red.
On a panel, a green LED indicates “inactive” and a red LED indicates “active.”
Note: The location of alarms on the Status panels is pre-defined, and is not affected by alarm severity.
To use the Status window:
1. Click
2. Click the tab for the alarm category you want to view.
Alarm Log window
The Alarm Log window selects information from alarm history, and lists all alarms of the following types:

All inactive but unacknowledged Fault and Information alarms
Ignore alarms are never listed.
You can acknowledge alarms from the Alarm Log window.
ProLink > Status.
In the Alarm Log window:
The alarms are organized into two categories: High Priority and Low Priority. Each category is displayed on a separate panel.
On a panel, a green LED indicates “inactive but unacknowledged” and a red LED indicates “active.”
Note: The location of alarms on the Alarm Log panels is pre-defined, and is not affected by alarm severity.
To use the Alarm Log window:
1. Click
ProLink > Alarm Log.
2. Click the tab for the alarm category you want to view.
3. To acknowledge an alarm, click the
Ack checkbox. When the transmitter has processed the
command:
- If the alarm was inactive, it will be removed from the list.
- If the alarm was active, it will be removed from the list as soon as the alarm condition
clears.

7.6.3 Using a DeviceNet tool

Using the Diagnostics Object (0x66), you can view the status of a group of preselected alarms, view information about a specific alarm, acknowledge an alarm, and retrieve information from alarm history. For detailed information on the Diagnostics Object, see Table C-7, or see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.
To view the status of a group of preselected alarms, execute a Get for Attributes 12–17, 40, or 41.
Note: These are the same alarms that are displayed in the ProLink II Status window.
46 Micro Motion® Model 2400S Transmitters for DeviceNet
Using the Transmitter
To view information about a single alarm:
1. Execute a Set for Attribute 18, specifying the code for the alarm you want to check.
2. Execute a Get for Attribute 42, and interpret the data using the following codes:
0x00 = Acknowledged and cleared
0x01 = Active and acknowledged
0x10 = Not acknowledged, but cleared
0x11 = Not acknowledged, and active

Note: The alarm history is a circular buffer, and older records are overwritten by newer records. To determine whether a record is newer or older than another record, you must compare their timestamps.
2. Execute Gets for the following attributes:
Attribute 47: The alarm type
Attribute 49: The time that this alarm changed status
Attribute 48: The type of status change:
-1 = Alarm posted
- 2 = Alarm cleared

7.7 Using the totalizers and inventories

The totalizers keep track of the total amount of mass or volume measured by the transmitter over a period of time.
The inventories track the same values as the totalizers. Whenever totalizers are started or stopped, all inventories (including the API volume inventory and concentration measurement inventories) are started or stopped automatically. However, when totalizers are reset, inventories are not reset automatically – you must reset inventories separately. This allows you to use the inventories to keep running totals across multiple totalizer resets.
You can view all totalizer and inventory values using any of the communication tools: the display, ProLink II, or a DeviceNet tool. Specific starting, stopping, and resetting functionality depends on the tool you are using.

You can view current values for the totalizers and inventories with the display (if your transmitter has a display), ProLink II, or a DeviceNet tool.
With the display
You cannot view current totalizer or inventory values with the display unless the display has been configured to show them. See Section 8.9.5.
To view a totalizer or inventory value, refer to Figure 7-2 and:
1. Check for the word
TOTAL in the lower left corner of the LCD panel.
If Auto Scroll is enabled, wait until the desired value appears on the LCD panel. You can also
Scroll until the desired value appears.
If Auto Scroll is not enabled,
Scroll until the desired value appears.
2. Check the unit of measure to identify the process variable being displayed (e.g., mass, liquid volume, gas standard volume).
3. Check the unit of measure line to determine whether you are viewing a totalizer value or an inventory value:
Totalizer value: the unit of measure is a steady display.
Inventory value: the unit of measure alternates with one of the following:
-
MASSI (for Mass Inventory)
-
LVO L I (for Liquid Volume Inventory)
-
GSV I (for Gas Standard Volume Inventory)
TCORI (for API Temperature Corrected Inventory)
-
-
STDVI (for CM Standard Volume Inventory)
-
NETVI (for CM Net Volume Inventory)
-
STDMI (for CM Net Mass Inventory)
4. Read the current value from the top line of the display.

8.2 Configuring volume flow measurement for gas

Two types of volume flow measurement are available:
Liquid volume (the default)
•Gas standard volume
Only one type of volume flow measurement can be performed at a time (i.e., if liquid volume flow measurement is enabled, gas standard volume flow measurement is disabled, and vice versa). Different sets of volume flow measurement units are available, depending on which type of volume flow measurement is enabled (see Tables 6-3 and 6-4). If you will use a gas standard volume flow unit, additional configuration is required.
Note: If you will use the petroleum measurement application or the concentration measurement application, liquid volume flow measurement is required.
The method used to configure volume flow measurement for gas depends on the tool you are using: ProLink II or a DeviceNet tool.
Note: For complete configuration of volume flow measurement for gas, you must use either ProLink II or a DeviceNet tool. Using the display, you can only select a volume measurement unit from the set available for the configured volume flow type.

Cutoff type Default Comments
Mass flow 0.0 g/s Recommended setting: 5% of the sensor’s rated maximum flow rate
Liquid volume flow 0.0 L/s Limit: the sensor’s flow calibration factor in liters per second, multiplied by 0.2
Gas standard volume flow

Configuration and Use Manual 59
Cutoffs are user-defined values below which the transmitter reports a value of zero for the specified process variable. Cutoffs can be set for mass flow, liquid volume flow, gas standard volume flow, and density.
See Table 8-2 for cutoff default values and related information. See Section 8.3.1 for information on how the cutoffs interact with other transmitter measurements.
To configure cutoffs:
Using ProLink II, see Figure B-2.

Optional Configuration

8.3.1 Cutoffs and volume flow

If you are using liquid volume flow measurement:
The density cutoff is applied to the volume flow calculation. Accordingly, if the density drops below its configured cutoff value, the volume flow rate will go to zero.
The mass flow cutoff is not applied to the volume flow calculation. Even if the mass flow drops below the cutoff, and therefore the mass flow indicators go to zero, the volume flow rate will be calculated from the actual mass flow process variable.
If you are using gas standard volume flow measurement, neither the mass flow cutoff nor the density cutoff is applied to the volume flow calculation.

8.4 Configuring the damping values

A damping value is a period of time, in seconds, over which the process variable value will change to reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small, rapid measurement fluctuations.
A high damping value makes the output appear to be smoother because the output must change slowly.
A low damping value makes the output appear to be more erratic because the output changes more quickly.
Damping can be configured for flow, density, and temperature.
When you change the damping value, the specified value is automatically rounded down to the nearest valid damping value. Valid damping values are listed in Table 8-3.
Note: For gas applications, Micro Motion recommends a minimum flow damping value of 2.56.
Before setting the damping values, review Section 8.4.1 for information on how the damping values affect other transmitter measurements.
Table 8 -3 Valid damping values
Process variable Valid damping values
Flow (mass and volume) 0, 0.04, 0.08, 0.16, ... 40.96
Density 0, 0.04, 0.08, 0.16, ... 40.96
Temperature 0, 0.6, 1.2, 2.4, 4.8, ... 76.8
To configure damping values:
Using ProLink II, see Figure B-2.

8.4.1 Damping and volume measurement

When configuring damping values, note the following:
Liquid volume flow is derived from mass and density measurements; therefore, any damping applied to mass flow and density will affect liquid volume measurement.
Gas standard volume flow is derived from mass flow measurement, but not from density measurement. Therefore, only damping applied to mass flow will affect gas standard volume measurement.
Be sure to set damping values accordingly.

8.5 Configuring the flow direction parameter

The flow direction parameter controls how the transmitter reports flow rate and how flow is added to or subtracted from the totalizers, under conditions of forward flow, reverse flow, or zero flow.
Forward (positive) flow moves in the direction of the arrow on the sensor.
Reverse (negative) flow moves in the direction opposite of the arrow on the sensor.
The options for flow direction and their effects on flow values and flow totals are shown in Table 8-4.

8.6 Configuring events

An event occurs if the real-time value of a user-specified process variable varies above or below a user-specified value, or inside or outside a user-specified range. You can configure up to five events.
You may optionally specify one or more actions that will occur if the event occurs. For example, if Event 1 occurs, you may specify that the transmitter will stop all totalizers and inventories and reset the mass totalizer.

8.6.1 Defining events

To define an event:
Using ProLink II, see Figure B-3.
Using a DeviceNet tool, event specifications reside in the Diagnostics Object (0x66), Instance 1. See Table C-7.
The following general steps are required:
1. Select the event to define (Attribute 6).
2. Specify the event type (Attribute 7). Event Type options are defined in Table 8-5.
3. Assign a process variable to the event (Attribute 10).
4. Specify the event’s setpoint(s) – the value(s) at which the event will occur or switch state (ON to OFF, or vice versa).
If Event Type is High or Low, only Setpoint A is used (Attribute 8)
If Event Type is In Range or Out of Range, both Setpoint A and Setpoint B (Attributes 9
and 10) are required.
5. Assign the event to an action or actions, if desired. Possible actions are listed in Table 8-6. To do this:
Using ProLink II, open the Discrete Input panel in the Configuration window, identify the
action to be performed, then specify the event using the drop-down list. See Figure B-3.
Note: For consistency with other Micro Motion products, the Discrete Input panel is used here even though the Model 2400S DN transmitter does not provide a discrete input.
Using the display, see Figure B-6 and use the ACT submenu.
Using a DeviceNet tool, refer to Table C-7, use Attribute 84 to specify the action to be
performed, and set Attribute 85 to specify which event will initiate the action.

1. Specify lb/min as the mass flow unit. See Section 6.3.1.
2. Configure the Flow Direction parameter for bidirectional flow. See Section 8.5.
3. Select Event 1.
4. Configure:
Event Type = Low
Process Variable (PV) = Mass Flow Rate
Low Setpoint (A) = 2
5. In the Discrete Input panel, open the drop-down list for Start/Stop All Totalization and select Discrete Event 1.
Using a DeviceNet tool:
1. Specify lb/min as the mass flow unit. See Section 6.3.1.
2. Configure the Flow Direction parameter for bidirectional flow. See Section 8.5.
3. In the Diagnostics Object (0x66), Instance 1, set the following attributes:
Discrete event index (Attribute 6) = 0
Discrete event action (Attribute 7) = 1
Discrete event process variable (Attribute 10) = 0
Discrete event setpoint A (Attribute 8) = 2
Discrete event action code (Attribute 84) = 9
Discrete event assignment (Attribute 85) = 57

8.6.2 Checking and reporting event status

There are several ways that event status can be determined:
ProLink II automatically displays event information on the Informational panel of the Status window.
The status of each event is stored in the Diagnostics Object (0x66), Instance 1, Attribute 11. For more information, see Table C-7, or see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.

8.6.3 Changing event setpoints from the display

For Event 1 or Event 2 only, the value of Setpoint A can be changed from the display, under the following circumstances:
Mass total or volume total (gas or liquid) must be assigned to the event.
The event type must be either High or Low.
Mass total or volume total must be configured as a display variable (see Section 8.9.5).
Then, to reset Setpoint A from the display:
1. Referring to the totalizer management flowchart in Figure 7-3, display screen:

Select.
3. Enter the new setpoint value. See Section 3.5.5 for instructions on entering floating-point values with the display.

8.7 Configuring slug flow limits and duration

Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications. The presence of slugs can significantly affect the process density reading. The slug flow parameters can help the transmitter suppress extreme changes in process variables, and can also be used to identify process conditions that require correction.
Slug flow parameters are as follows:
Slug flow low limit – the point below which a condition of slug flow will exist. Typically, this
is the lowest density point in your process’s normal density range. Default value is range is
0.0–10.0 g/cm

If the transmitter detects slug flow:
A slug flow alarm is posted immediately.
During the slug duration period, the transmitter holds the mass flow rate at the last measured pre-slug value, independent of the mass flow rate measured by the sensor. The reported mass flow value is set to this value, and all internal calculations that include mass flow rate will use this value.
If slugs are still present after the slug duration period expires, the transmitter forces the mass flow rate to reported as
0, independent of the mass flow rate measured by the sensor. Mass flow rate is
0 and all internal calculations that include mass flow rate will use 0.
When process density returns to a value within the slug flow limits, the slug flow alarm is cleared and the mass flow rate reverts to the actual measured value.
Configuration and Use Manual 65
Optional Configuration
To configure slug flow parameters:
Using ProLink II, use the Density panel in the Configuration window. See Figure B-2.
Using a DeviceNet tool, set Attributes 3, 4, and 5 in the Diagnostics Object (0x66), Instance 1. See Table C-7.
Note: This functionality is not available via the display menus.
Note: The slug flow limits must be entered in g/cm density. Slug flow duration is entered in seconds.
Note: Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility of slug flow conditions. Conversely, lowering the low slug flow limit or raising the high slug flow limit will decrease the possibility of slug flow conditions.
Note: If slug flow duration is set to 0, the mass flow rate will be forced to 0 as soon as slug flow is detected.

8.10.4 Modbus address

Note: The Modbus address is applicable only when you are connecting to the service port from a tool that uses Modbus protocol. After initial startup, service port connections are typically used only for troubleshooting or for specific procedures such as temperature calibration. ProLink II is typically used for service port connections, and by default ProLink II will use the standard service port address rather than the configured Modbus address. See Section 4.4 for more information.
The set of valid Modbus addresses depends on whether or not support for Modbus ASCII is enabled or disabled (see Section 8.10.5). Valid Modbus addresses are as follows:
Modbus ASCII enabled:
1–15, 32–47, 64–79, 96–110
Modbus ASCII disabled: 0–127
To configure the Modbus address:
Using ProLink II, see Figure B-2.
Using the display menus, see Figure B-6.

8.10.5 Modbus ASCII support

When support for Modbus ASCII is enabled, the service port can accept connection requests that use either Modbus ASCII or Modbus RTU. When support for Modbus ASCII is disabled, the service port cannot accept connection requests that use Modbus ASCII. Only Modbus RTU connections are accepted.
The primary reason to disable Modbus ASCII support is to allow a wider range of Modbus addresses for the service port.
To enable or disable Modbus ASCII support:
Using ProLink II, see Figure B-2.
Using the display menus, see Figure B-6.

8.10.6 IrDA port usage

The IrDA port on the display can be enabled or disabled. If enabled, it can be set for read-only or read/write access.
To enable or disable the IrDA port:
Using ProLink II, see Figure B-2.
Using the display menus, see Figure B-6.
Using a DeviceNet tool, see Table C-9.

8.10.7 Digital communications fault action

Digital communications fault action controls how digital communications will be affected by fault conditions. Table 8-12 lists the options for digital communications fault action.
Note: Digital communications fault action does not affect the alarm status bits. For example, if digital communications fault action is set to None, the alarm status bits will still be set if an alarm occurs. See Section 7.6 for more information.

8.10.8 Fault timeout

By default, the transmitter activates the digital communications fault action as soon as the fault is detected. The fault timeout allows you to delay the digital communications fault action for a specified interval, for certain faults only. During the fault timeout period, digital communications behaves normally.
Note: The fault timeout applies only to the digital communications fault action. The “alarm active” status bit is set as soon as the fault is detected (all alarm severity levels), and the “alarm active” record is written to history immediately (Fault and Informational alarms only). For more information on alarm handling, see Section 7.6. For more information on alarm severity, see Section 8.8.
The fault timeout applies only to specific faults. Other faults are reported immediately, regardless of the fault timeout setting. For information on which faults are affected by the fault timeout, see Tabl e 8-8.

8.13 Configuring the petroleum measurement application

The API parameters determine the values that will be used in API-related calculations. The API parameters are available only if the petroleum measurement application is enabled on your transmitter.
Note: The petroleum measurement application requires liquid volume measurement units. If you plan to use API process variables, ensure that liquid volume flow measurement is specified. See Section 8.2.

8.13.1 About the petroleum measurement application

Some applications that measure liquid volume flow or liquid density are particularly sensitive to temperature factors, and must comply with American Petroleum Institute (API) standards for measurement. The petroleum measurement enables Correction of Temperature on volume of Liquids, or CTL.
76 Micro Motion® Model 2400S Transmitters for DeviceNet
Optional Configuration
Terms and definitions
The following terms and definitions are relevant to the petroleum measurement application:
API – American Petroleum Institute
CTL – Correction of Temperature on volume of Liquids. The CTL value is used to calculate
the VCF value
TEC – Thermal Expansion Coefficient
VCF – Volume Correction Factor. The correction factor to be applied to volume process
variables. VCF can be calculated after CTL is derived
CTL derivation methods
There are two derivation methods for CTL:
Method 1 is based on observed density and observed temperature.
Method 2 is based on a user-supplied reference density (or thermal expansion coefficient, in some cases) and observed temperature.
API reference tables
Reference tables are organized by reference temperature, CTL derivation method, liquid type, and density unit. The table selected here controls all the remaining options.

The concentration measurement application calculates concentration measurement process variables, such as concentration or density at reference temperature, from density process data, appropriately corrected for temperature.
Note: For a detailed description of the concentration measurement application, see the manual entitled Micro Motion Enhanced Density Application: Theory, Configuration, and Use.
Note: The concentration measurement application requires liquid volume measurement units. If you plan to use concentration measurement process variables, ensure that liquid volume flow measurement is specified. See Section 8.2.

8.14.1 About the concentration measurement application

The concentration measurement calculation requires an concentration measurement curve, which specifies the relationship between temperature, concentration, and density for the process fluid being measured. Micro Motion supplies a set of six standard concentration measurement curves (see Table 8-16). If none of these curves is appropriate for your process fluid, you can configure a custom curve or purchase a custom curve from Micro Motion.
The derived variable, specified during configuration, controls the type of concentration measurement that will be produced. Each derived variable allows the calculation of a subset of concentration measurement process variables (see Table 8-17). The available concentration measurement process variables can be used in process control, just as mass flow rate, volume flow rate, and other process variables are used. For example, an event can be defined on an concentration measurement process variable.
For all standard curves, the derived variable is Mass Conc (Dens).
For custom curves, the derived variable may be any of the variables listed in Table 8-17.

The transmitter can hold up to six curves at any given time, but only one curve can be active (used for measurement) at a time. All curves that are in transmitter memory must use the same derived variable.

Pressure Compensation and Temperature Compensation

9.1 Overview

This chapter describes the following procedures:
Configuring pressure compensation – see Section 9.2
Configuring external temperature compensation – see Section 9.3
Obtaining external pressure or temperature data – see Section 9.4
Note: All ProLink II procedures provided in this chapter assume that you have established communication between ProLink II and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements. See Chapter 4 for more information.
Note: All DeviceNet tool procedures provided in this chapter assume that you have established communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements. See Chapter 5 for more information.

9.2 Pressure compensation

The Model 2400S DN transmitter can compensate for the effect of pressure on the sensor flow tubes. Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure change away from calibration pressure.
Note: Pressure compensation is an optional procedure. Perform this procedure only if required by your application.
Measurement Performance DefaultsTroubleshootingCompensation

9.2.1 Options

There are two ways to configure pressure compensation:
If the operating pressure is a known static value, you can configure that value in the transmitter.
If the operating pressure varies significantly, you must write a pressure value to the transmitter at appropriate intervals, using an appropriate output assembly. See Section 9.4.
Note: Ensure that your pressure value is accurate, or that your pressure measurement device is accurate and reliable.

9.2.2 Pressure correction factors

When configuring pressure compensation, you must provide the flow calibration pressure – the pressure at which the flowmeter was calibrated (which therefore defines the pressure at which there will be no effect on the calibration factor). Enter sensor indicates a different calibration pressure.
Two additional pressure correction factors may be configured: one for flow and one for density. These are defined as follows:
Flow factor – the percent change in the flow rate per psi
Density factor – the change in fluid density, in g/cm
Not all sensors or applications require pressure correction factors. For the pressure correction values to be used, obtain the pressure effect values from the product data sheet for your sensor, then reverse the signs (e.g., if the pressure effect is
0.000004, enter a pressure correction factor of –0.000004).

9.3 External temperature compensation

External temperature compensation can be used with the petroleum measurement application or the concentration measurement application.
Note: The external temperature value is used only for calculation of the derived variable in concentration measurement applications or the CTL value in petroleum measurement applications. The temperature value from the sensor is used for all other calculations that require a temperature value.

10.2 Meter validation, Smart Meter Verification, and calibration

The Model 2400S transmitter supports the following procedures for the evaluation and adjustment of measurement performance:
Smart Meter Verification – establishing confidence in the sensor’s performance by analyzing
secondary variables associated with flow and density
Meter validation – confirming performance by comparing the sensor’s measurements to a
primary standard
Calibration – establishing the relationship between a process variable (flow, density, or
temperature) and the signal produced by the sensor
Meter validation and calibration are available on all Model 2400S DN transmitters. Smart Meter Verification is available only if the Smart Meter Verification option was ordered with the transmitter.
These three procedures are discussed and compared in Sections 10.2.1 through 10.2.4. Before performing any of these procedures, review these sections to ensure that you will be performing the appropriate procedure for your purposes.
Configuration and Use Manual 89
Measurement Performance

10.2.1 Smart Meter Verification

Smart Meter Verification evaluates the structural integrity of the sensor tubes by comparing current tube stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or force divided by displacement. Because a change in structural integrity changes the sensor’s response to mass and density, this value can be used as an indicator of measurement performance. Changes in tube stiffness are typically caused by erosion, corrosion, or tube damage.
Smart Meter Verification does not affect measurement in any way. Micro Motion recommends performing Smart Meter Verification at regular intervals.

10.2.2 Meter validation and meter factors

Meter validation compares a measurement value reported by the transmitter with an external measurement standard. Meter validation requires one data point.
Note: For meter validation to be useful, the external measurement standard must be more accurate than the sensor. See the sensor’s product data sheet for its accuracy specification.
If the transmitter’s mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor. A meter factor is the value by which the transmitter multiplies the process variable value. The default meter factors are
1.0, resulting in no difference between the data retrieved from the sensor and the data
reported externally.
Meter factors are typically used for proving the flowmeter against a weights and measures standard. You may need to calculate and adjust meter factors periodically to comply with regulations.

10.2.3 Calibration

The flowmeter measures process variables based on fixed points of reference. Calibration adjusts those points of reference. Three types of calibration can be performed:
Zero, or no flow
Density calibration
Temperature calibration
Density and temperature calibration require two data points (low and high) and an external measurement for each. Zero calibration requires one data point. Calibration produces a change in the offset and/or the slope of the line that represents the relationship between the actual process value and the reported value.
Note: For density or temperature calibration to be useful, the external measurements must be accurate.
Micro Motion flowmeters with the Model 2400S transmitter are calibrated at the factory, and normally do not need to be calibrated in the field. Calibrate the flowmeter only if you must do so to meet regulatory requirements. Contact Micro Motion before calibrating your flowmeter.
Note: Micro Motion recommends using meter validation and meter factors, rather than calibration, to prove the meter against a regulatory standard or to correct measurement error.

10.2.4 Comparison and recommendations

When choosing among Smart Meter Verification, meter validation, and calibration, consider the following factors:
Process and measurement interruption
- Smart Meter Verification provides an option that allows process measurement to continue during the test.
- Meter validation for density does not interrupt the process. However, meter validation for mass flow or volume flow requires process down-time for the length of the test.
- Calibration requires process down-time. In addition, density and temperature calibration require replacing the process fluid with low-density and high density fluids, or low-temperature and high-temperature fluids. Zero calibration requires stopping flow through the sensor.
External measurement requirements
- Smart Meter Verification does not require external measurements.
- Zero calibration does not require external measurements.
- Density calibration, temperature calibration, and meter validation require external measurements. For good results, the external measurement must be highly accurate.
Measurement adjustment
- Smart Meter Verification is an indicator of sensor condition, but does not change flowmeter internal measurement in any way.
- Meter validation does not change flowmeter internal measurement in any way. If you decide to adjust a meter factor as a result of a meter validation procedure, only the reported measurement is changed – the base measurement is not changed. You can always reverse the change by returning the meter factor to its previous value.
Measurement Performance DefaultsTroubleshootingCompensation
- Calibration changes the transmitter’s interpretation of process data, and accordingly changes the base measurement. If you perform a zero calibration, you can return to the previous zero or the factory zero. However, if you perform a density calibration or a temperature calibration, you cannot return to the previous calibration factors unless you have manually recorded them.
Micro Motion recommends obtaining the Smart Meter Verification transmitter option and performing Smart Meter Verification on a regular basis.

10.3 Performing Smart Meter Verification

Note: To use Smart Meter Verification, the Smart Meter Verification option must be purchased for the transmitter.

10.3.1 Preparing for the Smart Meter Verification test

The Smart Meter Verification procedure can be performed on any process fluid. It is not necessary to match factory conditions.
During the test, process conditions must be stable. To maximize stability:
Maintain a constant temperature and pressure.
Avoid changes to fluid composition (e.g., two-phase flow, settling, etc.).
Maintain a constant flow. For higher test certainty, stop flow.
Configuration and Use Manual 91
Measurement Performance
If stability varies outside test limits, the Smart Meter Verification procedure will be aborted. Verify the stability of the process and retry the test.
Transmitter configuration
Smart Meter Verification is not affected by any parameters configured for flow, density, or temperature. It is not necessary to change the transmitter configuration.
Control loops and process measurement
If the transmitter outputs will be set to Last Measured Value or Fault during the test, the outputs will be fixed for two minutes. Disable all control loops for the duration of the test, and ensure that any data reported during this period is handled appropriately.

10.3.2 Running the Smart Meter Verification test

To run a Smart Meter Verification test:
With ProLink II, see Figure 10-1.
Note: If you start a Smart Meter Verification test from ProLink II, and the outputs are set to Last Measured Value or Fault, the transmitter display shows the following message:
SENSOR VERFY/x%
With the display, see Figures 10-2 and 10-3.
With a DeviceNet tool, see Figure 10-4.
- To start Smart Meter Verification in Fault or Last Measured Value mode, first set the Output State and then start the procedure with code 1.
- To start Smart Meter Verification in Continue Measurement mode, you do not need to set the Output State. Simply start the procedure with code 6.
