1.1 Overview

This chapter provides an orientation to the use of this manual, and includes a pre-configuration

worksheet. This manual describes the procedures required to start, configure, use, maintain, and

troubleshoot the Micro Motion

Model 3711 Gas Flow Computer system.

1.2 Safety

Safety messages are provided throughout this manual to protect personnel and equipment. Read each

safety message carefully before proceeding to the next step.

1.3 About the Model 3711 Gas Flow Computer

The Micro Motion Model 3711 is a compact, high-performance gas flow computer specifically

designed to provide fiscal measurement data for gas applications. The Model 3711 uses a Micro

Motion Coriolis sensor with MVD

™

technology to measure the gas flow.

The Model 3711 system performs flow measurement compliant with API MPMS Chapter 21.1a in

accordance with the AGA8-92 gas measurement standard.

1.3.1 Model 3711 system components

The Model 3711 system includes the following components:

• Model 3711 Gas Flow Computer

• Micro Motion sensor

• Micro Motion core processor (may be mounted on sensor)

• MVD Direct Connect

™

I.S. barrier

See Figures A-1 and A-2 for diagrams.

1.3.2 User programs

The Model 3711 functionality is implemented via two user programs:

• Core Interface – handles communication between the Model 3711 and the sensor; performs

the sensor zero and density calibration procedures

• Gas Flow Computer Calculations – performs volumetric flow measurement and displays flow

rates and totals; manages pressure compensation on mass flow rate

These two programs are preloaded onto the Model 3711.

1.3.3 Implementation overview

A typical Model 3711 gas measurement system is configured to write measurement data to history at

minute, hourly, daily, and user-specified intervals. The history data is then delivered to an external

system for various accounting and analysis procedures. The delivery interval is controlled by the user.

The event and alarm logs contain information related to configuration changes and various system

conditions. Events and alarms are logged automatically. The event and alarm logs may also be

delivered to an external system.

Two methods for delivering history, event, and alarm data are available:

• Manual – The user manually saves the history, event, or alarm data to a file, and then sends the

file to the appropriate parties.

• Remote communications – A host system connects to the Model 3711 and retrieves the history

data. The host communications program may use either Modbus or ROC protocol.

- If Modbus protocol will be used, the Modbus interface on the Model 3711 must be

configured.

- No special setup is required to use ROC protocol.

Measurement data may also be viewed on the Model 3711 LCD, or on various ROCLINK

™

800

windows.

1.4 Communication tools

A special version of the ROCLINK 800 software program has been developed for configuration,

operation, and maintenance of the Model 3711. This version is written to include the two user

programs described in Section 1.3.2, which are presented as custom displays accessed via the Meter

menu. This version of ROCLINK 800 is available from Micro Motion. Installation and basic use of

ROCLINK 800 is discussed in Chapter 2.

If desired, a host program may be written to communicate with the Model 3711.

1.5 Model 3711 configuration overview

To get the Model 3711 system into operation using default values for most parameters, follow the

“quick start” steps in Section 1.5.1. The default values have been defined to provide the required

measurement and history data for most applications.

Section 1.5.2 lists the tasks involved in a basic setup and configuration. Chapters 2 through 8 of this

manual present the required tasks in the order listed here.

ROCLINK 800 buttons

Several buttons are used to manage the ROCLINK 800 interface or data exchange with the

Model 3711 component. They do not interact with the core processor component. These buttons are

found on many ROCLINK 800 windows and dialog boxes (see Figure 2-4):

•

OK – Closes the current window or dialog box. If there are any unsaved changes on the screen,

a popup is displayed, asking the user if the changes should be saved to the Model 3711

configuration.

•

Apply – Writes the configuration parameters that are currently shown on the ROCLINK 800

display to the Model 3711 configuration.

•

Cancel – Closes the current window or dialog box without changing any parameters, and

without displaying a confirmation popup.

•

Update – Updates the display from current values in the Model 3711.

•

Auto Scan and Stop Scan – Enables and disables the Auto Scan feature. Auto Scan

automatically updates the display from the Model 3711, at configured intervals. See

Section 3.5 for information on configuring the Auto Scan interval.

If Auto Scan is not enabled, it may be useful to click

Apply, then click Update, so that the screen

displays the results of your actions.

Figure 2-4 Common buttons

Two additional buttons – the

Write Config and Read Config buttons – manage data exchange with

the core processor component as well as the Model 3711 component:

•The

Write Config Data button writes the displayed configuration parameters to the core

processor. If you have changed a parameter in ROCLINK 800, but not written it to the

Model 3711, a popup is displayed to allow you to save the change to the Model 3711.

- If you click

Yes, the change is saved to the Model 3711, and then written to the core

processor.

- If you click

No, the change is discarded and nothing is written to the Model 3711 or the

core processor.

•The

Read Config Data button reads configuration parameters from the core processor and

updates the ROCLINK 800 display. If you have changed a parameter in ROCLINK 800 but

not written it to the Model 3711, a popup is displayed to allow you to save the change.

- If you click

Yes, the change is written to the Model 3711 and the core processor before

values are read back to the display.

- If you click

No, the change is discarded and the existing values in the core processor are

read back to the display.

These buttons appear only on the Mass Flow, Density, and Temperature panels (see Section 5.4).

Note: The core processor is the component which provides preprocessing of the sensor data. In the

Model 3711 system, ROCLINK 800 communicates with the Model 3711 component, which in turn

communicates with the core processor component, which communicates with the sensor.

2.4.3 TLP system

Particular locations, or “points,” in Model 3711 memory are identified using a TLP system, where:

•T = Type

• L = Logical number

•P = Parameter

For example, a TLP value of

AOU B3, EU represents the value, in engineering units, of the analog

output associated with point B3 in the Model 3711’s physical memory.

ROCLINK 800 uses the TLP system during configuration. When the TLP symbol (an ellipsis, or

...) is

displayed on a button, the button provides access to the Select TLP dialog box, shown in Figure 2-5.

Figure 2-5 Select TLP dialog box

TLP notation can be text, as shown here, or numeric. For example, if numeric notation is configured,

AOU B3, EU will be represented as 4 18, 6. See Section 3.5 for information on configuring TLP

notation.

To use the Select TLP dialog box:

1. Highlight the point type of the desired point.

2. Highlight the logical number of the desired point.

3. Highlight the desired parameter associated with the specified point.

See Appendix C for additional information on points and the TLP system.

Configuration and Use Manual 11

Getting Started

Getting Started CommunicationsSystemBefore You Begin

2.5 Configuration files

When using ROCLINK 800 to configure the Model 3711, two types of configuration files are

involved:

• The ROCLINK 800 configuration file is specific to each installation of ROCLINK 800 on a

PC. It is created automatically, and automatically saved to a file each time that ROCLINK 800

is closed. It contains device and group definitions (see Section 2.6), and other items that are

specific to the ROCLINK 800 software, rather than to a device. No user actions are required to

create and maintain the ROCLINK 800 configuration file.

• A device configuration file is a set of operating parameters that are defined in ROCLINK 800,

then applied or downloaded to the Model 3711. Multiple device configuration files may be

defined in ROCLINK 800, and stored as files on the PC; however, only one device

configuration file can be loaded into the Model 3711 at any one time. A device configuration

file must be specifically created and saved by the user.

2.5.1 Managing device configuration files

The ROCLINK 800 File menu is used to open and close device configuration files within

ROCLINK 800, and to save a device configuration file to the PC. The File menu is also used to print a

device configuration file (see Section 14.11) and to download a device configuration file into the

Model 3711 (see Section 14.10.3).

All device configuration files use the .800 extension. You can create as many device configuration

files as you need. Each device configuration file contains information describing one Model 3711,

including its interaction with the sensor, its I/O configuration, its history setup, and so on.

Note: If you use this installation of ROCLINK 800 to interact with other devices, including

non–Model 3711 devices, their device configuration files will also use the .800 extension. Be sure to

name the device configuration files so that you will be able to identify the device and device type.

Only one device configuration file can be loaded to a Model 3711. However, multiple device

configuration files can be open within ROCLINK 800 at one time. Each device configuration file

displayed in a separate Configuration Tree window. The Window menu can be used to select the

device configuration file that you want to view or use.

Saving a device configuration file to the PC is not the same as saving it to flash memory in the

Model 3711. To save a device configuration to flash memory, click

Device > Flags >

Save Configuration

. The configuration data in flash memory is used in all cold restarts, and may be

used in warm restarts. For more information on flash memory and restart options, see Section 14.2.

2.5.2 Creating a new device configuration file

You do not have to be connected to a Model 3711 to create a device configuration file. However, you

will need to be connected to a Model 3711 to configure many of the properties that are saved in a

device configuration file.

To create a new device configuration file:

1. Click

File > New.

2. In the upper left corner of the New Configuration File window, set

Configuration Type to

FB104/3711. The shown in Figure 2-6 is displayed.

Figure 2-6 New Configuration File dialog box

3. Specify your I/O type.

• If your Model 3711 was ordered without the optional 6-point I/O expansion termination

board, select

6-point no I/O.

• If your Model 3711 was ordered with the optional 6-point I/O expansion termination

board, select

6-point with I/O.

4. If you specified

6-point with I/O, an External I/O frame is displayed. Use the options in this

frame to specify how five of the six I/O channels will be used (the sixth channel is always used

as a discrete output). The I/O types specified here must be compatible with the I/O wiring and

switches (see the Model 3711 installation manual for wiring instructions). You can change

these specifications later (see Section 7.3).

5. Specify the number of PID control loops that will be configured for this Model 3711. The

maximum value is 1. This value can be changed later. See Chapter 10 for more information.

6. Specify the maximum number of history points to be used for standard history and extended

history. If you add history points later, you will lose all existing history, so make sure that the

number specified will be sufficient for your Model 3711. See Chapter 8 for more information

about history.

7. Click

Start.

8. Specify a name and location to be used for the configuration file, and click

Save. All

ROCLINK 800 configuration files use the .800 extension.

9. If you want to continue with configuration, open the file when prompted. If you will perform

configuration later, close the file.
