Overview of the Frequency Input Module 5
A broader view of how the FLEX I/O module interfaces with the different
elements in a Logix system is shown in the sample illustration below.
In this example, the FLEX I/O module communicates with the controller
through the adapter. The controller can produce and consume tags. It can
initiate MSG instructions that send and receive data or configure devices.
Configuration of devices and the network is done through the personal
computer running the controller and configuration software.
To learn about the steps to configure your FLEX I/O module, see Configure
Your FLEX I/O Module with RSLogix 5000 Software on page 29.

Typical Applications
You can use the frequency input modules in power management, automotive,
food and beverage, and oil and gas industries for various flow and/or turbine
metering applications. Some sample applications include:
• turbine shaft speed monitoring
• automotive paint booths
• brewery flow monitoring
• petrochemical flow and custody transfer
