Chapter

General

PROFIBUS Adapter Overview

This chapter describes the purpose of the POINT I/O PROFIBUS adapter, and what tasks have to be performed after installing the adapter.

For more information about: See page:

PROFIBUS Adapter Overview 1-1

Startup Procedure 1-2

Chapter Summary and What’s Next 1-4

The POINT I/O 1734-APB adapter resides on the PROFIBUS network and the POINT I/O backplane (PointBus) simultaneously. From this position, the adapter interfaces between the PROFIBUS network and the POINT I/O modules. The illustration below shows the adapter on the PROFIBUS network and the PointBus.

The adapter functions are:

• PROFIBUS - adapter serves as a slave that exchanges I/O data

with a PROFIBUS master.

• PointBus - the adapter serves as a master that communicates

with up to 63 POINT I/O modules

1 Publication 1734-UM005B-EN-P - June 2001

1-2 What is the PROFIBUS Adapter

Communicating through the Adapter

Output data is sent from the master across the PROFIBUS network to the 1734-APB adapter. The adapter automatically transfers the data across the PointBus backplane to the output modules.

Inputs from the input modules are collected by the PROFIBUS adapter via the backplane and sent across the PROFIBUS network to the master.

I/O Module Removal and Insertion Under Power

I/O modules can be removed under power from their positions in the backplane without interfering with the communication with the other modules. When reinserting the removed module, communication is automatically started up again if the following criteria is fulfilled:

1. The inserted module is the same type as the one removed.

Startup Procedure

2. If more than one module is removed, communication will not be

regained until all modules are inserted in their correct positions again.

Starting the adapter module consists of:

• Installing the adapter in the system

• setting the adapter node address

• configuring the adapter for PROFIBUS communication

• configuring the I/O modules for PointBus communication

Set the Adapter Node Address

Set the node address using the 2-position thumbwheel switch. Valid

settings range from 01 to 99. Use a pen to press either the + or – buttons to change the number.

Publication 1734-UM005B-EN-P - June 2001

What is the PROFIBUS Adapter 1-3

Configure the Adapter for PROFIBUS Communication

• Install the GSD file you received into your configuration tool

• add the adapter to your configuration

• select the node address and baud rate

• add I/O modules to the configuration

For more information, refer to Chapter 3 - Configuring the POINT I/O System.

Configure the I/O Modules for PointBus Communication

You must configure each I/O module to establish its actions on the PointBus. Each module has a set of parameters that can be set (i.e. Idle value, Fault value, etc.).

For more information, refer to Chapter 3 - Configuring the POINT I/O System.

1-4 What is the PROFIBUS Adapter

Diagnostic Indicators

Diagnostic indicators are located on the front panel of the adapter module. They show both normal operation and error conditions in your POINT I/O system. The indicators are:

• Adapter status

• PROFIBUS status

• PointBus status

• System power

• Field power

Upon power-up, the adapter goes to an initialization state and performs a self-test (memory check, data memory clear, firmware integrity). 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. Chapter 6 describes the diagnostic indicators and how to use them for troubleshooting.

Network Connector

Use the 9-pin D-shell connector (shown below) to connect your adapter to the PROFIBUS network.

Connections are provided for connecting the required 24V dc power to the front of the module.

Refer to Chapter 2 or the Installation Instructions (pub. no. 1734-IN014) you received with your adapter to learn how to install and wire the adapter.

This chapter provided a brief overview of the 1734-APB PROFIBUS adapter. Go to chapter 2 to learn how to install and wire your adapter.

Chapter Summary and What’s Next 2-9

When properly installed, POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated, yellow chromated steel DIN rail to assure proper grounding.

Other DIN rail material (such as aluminum, plastic, etc.) can corrode or oxidize and are poor conductors that may result in improper or intermittent platform grounding.

If you choose not to use zinc plated, yellow chromated steel DIN rail for your POINT I/O, periodically clean the DIN rail to prevent or lessen the effects of oxidation and corrosion.

2-2 Installing the PROFIBUS Adapter

Installing the PROFIBUS Adapter

To install the adapter on the DIN rail prior to installing other base units, proceed as follows.

1. Position the adapter vertically above the DIN rail.

2. Press down firmly to install the adapter on the DIN rail. (The

locking mechanism will lock the adapter to the DIN rail.)

Module Power

The adapter supplies 5V logic power to POINT I/O modules by converting the applied 12/24V dc field power to PointBus 5V power.

You can connect up to 63 I/O modules to each adapter, and you can power up to 14 I/O modules from the adapter (with a maximum of 10A of field power). Add up the current requirements of the modules you want to use, and determine that they do not exceed the amperage limit of the 1734-APB. (Note: Total expansion up to 63 modules - 14 modules (with 75mA current draw) maximum with 1734-APB - add 1734-EP24DC modules for additional 14 modules (or less based on current requirements), up to 63 module maximum)

Installing the PROFIBUS Adapter 2-7

After the 14th (or last) module, you must insert an expansion power supply (cat. no. 1734-EP24DC) to power additional I/O modules.

Refer to the table below for various POINT I/O modules current requirements.

1. Connect chassis ground to terminal 2.

2. Connect 12/24V supply positive lead to terminal 6.

3. Connect 12/24V negative lead to terminal 4.

External power applied across terminal 6 (+) and 5 (-) connects to the internal power bus. Do not connect anything to terminals 0 and 1. These are reserved terminals.

4. Connect the PROFIBUS connector plug to the D-shell on the

adapter. Tighten the screws to secure.

Chapter Summary and What’s Next 3-14

Since the POINT I/O adapter is compatible with any master system, you can use any configuration tool available on the market. Just import the GSD file included on the diskette you received with your shipment of the adapter into your configuration tool. The configuration tool uses the GSD file to help you set up the system. The file is in raw ASCII format and you can view it with any text editor.

Throughout this chapter, we use the Sycon configuration software from HMS Industrial Networks as an example of how to configure the adapter. For information on how to configure your system, refer to the documentation associated with your master and configuration tool.

You must follow these steps during configuration:

1. Install the GSD file

2. Add the adapter to your PROFIBUS network

3. Add I/O modules to the adapter

4. Configure the modules

5. Download to master system
