Overview of the FLEX I/O PROFIBUS
APBDPV1 Module
Overview
Read this chapter to familiarize yourself with the adapter module.
The FLEX I/O System
The FLEX I/O system 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:
• 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

2Overview of the FLEX I/O PROFIBUS APBDPV1 Module
Purpose of the FLEX I/O
PROFIBUS
APBDPV1 Adapter
The 1794-APBDPV1 module is a FLEX I/O communications adapter that
interacts with the FLEX I/O backplane and any PROFIBUS DP master/scanner
controller on a PROFIBUS DP network.
The 1794-APBDPV1 module is a slave device to the DP master/scanner, and is a
master controller of the FLEX I/O system where it is installed. The I/O data
exchange occurs as follows: Output data is sent from the DP master/scanner
controller across the PROFIBUS DP network to the 1794-APBDPV1 adapter.
The adapter then automatically transfers the data across the FLEX I/O backplane
to the output modules. Inputs from the input modules are collected by the FLEX
I/O adapter via the backplane and sent across the PROFIBUS DP network to the
DP master/scanner controller.
Differences Between APB
and APBDPV1 Adapters
This section describes the differences between the 1794-APB FLEX I/O
PROFIBUS and the 1794-APBDPV1 FLEX I/O PROFIBUS APBDPV1
adapter modules.
DP-V1 Protocol
The FLEX I/O PROFIBUS APBDPV1 adapter uses a newer version of
PROFIBUS DP (DP1) protocol whereas the The FLEX I/O PROFIBUS
APB adapter uses the first generation PROFIBUS DP protocol (DP-0).
Functionality
The FLEX I/O PROFIBUS APBDPV1 adapter features Identification &
Maintenance (I&M) functions. These functions specify how certain device
describing data must be unambiguously stored in PROFIBUS devices essentially
enabling easy access to current information on the device. The adapter also
supports newer HART modules than the The FLEX I/O PROFIBUS APB
adapter.

Bandwidth and Range
The FLEX I/O PROFIBUS APB adapter baud-rate is now 12 MBd and,
although the physically PROFIBUS address range is still limited to 1..99, the
logical address range is 1..126.

Adapter Components
The adapter module consists of the following components:
• two diagnostic indicators
•PROFIBUSDPnetworkconnector
• 24V DC power wiring connection terminals
• two node address switches
Diagnostic Indicators
Diagnostic indicators are located on the front panel of the adapter module. They
show both normal operation and error conditions in your FLEX I/O system. The
indicators are:
• Device status (STATUS)
• Communication link status (PROFIBUS)
Upon power-up, the adapter goes to an initialization state and performs a self-test
(memory check, data memory clear, CRC on code). The indicators also go
through a self-test sequence. If a failure occurs, the adapter transitions to a faulted
state and waits for reset (cycle power). Otherwise, the adapter begins monitoring
the network (run state) for messages.
Network Connector
Use the 9-pin SUB-D connector to connect your adapter to the PROFIBUS
network.

Set the Node Address Switches
Set the thumbwheel switches to 00 to allow node addressing by software
configuration tool to set the range from 1…125. Address changes take effect only
after cycling power. Use a pen to press either the + or – buttons to change the
number.
Power Wiring
Connection terminals are provided for connecting the required 24V DC power
to the front of the module. The power wiring can be daisy-chained to the
terminal base unit located next to the adapter to supply power to the module
installed in that base unit.
Refer to the FLEX I/O PROFIBUS Communications Adapter Installation
Instructions, publication 1794-IN114, that you received with your adapter to
learn how to install and wire the adapter.
Mount and Remove
Your System
You can horizontally or vertically mount the FLEX I/O system on a standard
DIN rail. The adapter and terminal base easily snap on the DIN rail by hand.
Refer to the installation instructions shipped with these components.
Screw holes are also provided to horizontally or vertically panel-mount your
system in an enclosure. To panel-mount your FLEX I/O system, use the optional
mounting kit (1794-NM1). See Example of a DIN Rail-Mounted System on
page 5.
