Overview of FLEX I/O and Your Thermocouple, RTD, and Millivolt Input Module
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 the prerequisites and steps to configure your FLEX I/O module
using RSLogix 5000 software, see Configure Your FLEX I/O Module with
RSLogix 5000 Software on page 21.
