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
• Remote communications – A host system connects to the Model 3711 and retrieves the history
Measurement data may also be viewed on the Model 3711 LCD, or on various ROCLINK
windows.

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.

2.5 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
Save Configuration
. The configuration data in flash memory is used in all cold restarts, and may be

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.

2.5.3 Device configuration backup and duplication
Once a device configuration file has been saved to your PC, it can be downloaded to any Model 3711.
This feature allows you to replicate a configuration across multiple Model 3711 installations. When
downloading, you can select specific types of configuration data as required (see Section 14.10.3).
2.6 Setting up devices and groups
Each Model 3711 is a ROCLINK 800 device. All ROCLINK 800 devices can be organized into
groups. Typically, a group contains all Model 3711 devices within one geographical area.
You do not need to be connected to a Model 3711 to add devices or groups. Device and group
definitions are stored within ROCLINK 800.
The Device Directory window (see Figure 2-2) shows the predefined entities. To open the Device
Directory window, click
Window > Device Directory or View > Directory.
