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
windows.

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.

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.
Section 1.5.3 lists configuration options which may or may not be implemented in your application.
More information on these options is provided in Chapters 9 through 12.
