Overview of FLEX I/O and Your

PROFIBUS Adapter Module

This chapter describes:

• what the FLEX I/O system is and what it contains

• how to mount and remove your system easily

• optional accessories

• mounting dimensions and spacing requirements

• the 1794-APB FLEX I/O PROFIBUS Adapter

• adapter components

• how to connect power wiring

FLEX I/O is a small, modular I/O system for distributed

applications that performs all of the functions of rack-based I/O. The

FLEX I/O system contains the following components:

Adapter

Terminal Base

I/O Module



• PROFIBUS adapter/power supply – powers the internal logic for

as many as eight I/O modules

• terminal base – contains a terminal strip to terminate wiring for

two- or three-wire devices

• I/O module – contains the bus interface and circuitry needed to

perform specific functions related to your application

For information on how communication occurs over the FLEX I/O

system backplane, refer to Chapter 2.
