78 Configuring the Configurable Flowmeter Module
Using this Chapter
This chapter is broken into two sections:
 Overview of the Configuration Process - Includes a detailed explanation
of how to perform each task mentioned in the overview
 Examples of how to configure your CFM module for any of the
following operational modes:
– High resolution frequency mode
– Totalizer mode using the prover function
– Totalizer mode using the filler function
This chapter is intended to teach you how to configure the CFM module for
basic operation in each of the modes mentioned above. You should be able to
use the building blocks learned in this chapter to write more detailed
configuration for your CFM module in your specific application.
Overview of the
Configuration Process
When you create a CFM module, module-defined data structures and tags are
created in RSLogix 5000 software. The information contained in these
structures determines your CFM module’s behavior.
The owner-controller sends configuration information to the CFM module in
one of the following ways:
 RSLogix 5000 project goes online - Typically, this is the method in
which initial configuration is sent. When the project goes online, a
program is downloaded to the controller, and connections are made to
all devices that controller owns, including any CFM modules. When a
connection is established, the configuration for that particular module is
transferred.
 Message instructions - Typically, this method is used after module
operation has begun and additional configuration changes are necessary.
IMPORTANT
The examples offered in this chapter only list the tags that
need to be changed for specific operational modes. For a
complete listing of configuration, input and output tags, see
Appendix B.
IMPORTANT
This chapter assumes you have created a Logix controller in
a RSLogix 5000 project.
