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.

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.

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

3-6 Configuring the POINT I/O System

Adding I/O Modules to the Adapter

After you add the adapter, you must add the POINT I/O modules connected to the adapter in the backplane.

You can select any of 5 different types:

1. Modules with Configuration Data

If you select modules with configuration data (i.e. 1734-IB2), the configuration data would be available for you to manually

modify. Refer to “Configuring I/O Modules” later in this chapter.

2. Modules without Configuration Data

If you select modules without configuration data (i.e.1734-IB2/ No config data), you will not be able to change the configuration data. This data would be set to a default setting. However, you can still disable the diagnostic functionality for the module.

3. Empty Slot Modules

If you have a gap in the backplane, you should use an empty slot module (i.e. 1734-IB2/Empty slot). The empty slot module reserves memory space in your master for addition of a module at a later date.

4. Grouped Modules

In order to use memory more efficiently, modules can be grouped together in a single byte. The modules must be inserted next to each other and be of the same module family. Each module will have the same configuration as the first module in the group. Eight channels (1 byte) is the maximum allowed. Refer to chapters 4 and 5 for “Grouped Mode” information.

When configured for grouped mode, you can save user parameter data and I/O data.

5. Grouped Empty Slot Modules

If you have a gap in the backplane where the missing modules belong to a group, use a grouped empty slot module. Refer to chapter 4 for more information.

NOTE: In the following example, only modules with configuration data are used.

The modules you select are transferred to the adapter with the PROFIBUS Check_Config service. For a detailed description of the Check_Config service, refer to Chapter 4.

Image Table Mapping

The adapter must map the data it receives to its internal memory before passing it to the appropriate module. The image table map for a module is divided into:

• Read bytes - input and status bytes

• Write bytes - output and configuration bytes

The length of each module’s read bytes and write bytes vary in size depending on module complexity. The following illustration shows how the adapter maps information. Refer to appendix B for the data maps of the different POINT I/O modules.

4-2 Communication and I/O Table Mapping

How Data Communication Takes Place

Publication 1734-UM005B-EN-P - June 2001

Before any data transfer can take place, the adapter has to verify and accept the PROFIBUS services Set_Parameter and Check_Configuration that are sent from the master at startup. If the adapter accepts these services, data transmission is executed automatically in a cyclic manner with the Data_Exchange service. In addition to these 3 services, the adapter may notify the master of its current status by means of the Slave_Diagnostic service.

The master can read the actual configuration with the Get_Configuration service and send control commands to the adapter by means of the Global_Command service.

Communication and I/O Table Mapping 4-3

This section describes how the adapter handles the following services:

• Set_Parameter

• Check_Configuration

• Get_Configuration

• Data_Exchange

• Global_Command

• Slave_Diagnostic

Set_Parameter

The master uses this service to identify itself with the adapter and to specify how the adapter is to operate. Set_parameter data is comprised of a series of octets (maximum of 244). Octet 0-6 is defined in the DIN 19245-3 standard, while octet 7-243 contain specific information for the adapter itself (referred to as User Parameter Data). The module configuration you previously selected is passed on to the adapter and I/O modules via the User Parameter data.

Octet Value Description

0 - Station Status (see DIN 19245-3)

1 1-255 Watchdog Factor 1

2 1-255 Watchdog Factor 2

3 0-255 Minimum Station Delay (TSDR)

6 - Group Identification (see DIN 19245-3)

7-243 See below User Parameter Data

User Parameter Data

Octet 7 in the parameter data is reserved for the Profibus-DP ASIC onboard and must equal 00h.

Beginning at octet 8, each configured module allocates a minimum of three bytes of user parameter data as shown in the following table.

The first two bytes define the product code for the installed module, the third byte defines the control byte followed by configuration data (if used).

Product Code

The product code is used to determine the identity of the module installed in each slot. The code is defined in the GSD file and is automatically extracted by the configuration tool when you add the modules to your configuration. (Refer to appendix B for module product codes.) If an installed module does not match the product code for that slot, the slot is considered faulty and the adapter will respond to the Set_Parameter service with a negative acknowledgement. This will cause the master to set the Parameter fault bit in the Slave_Diagnostic service.

Note: Data exchange is not possible if the product code and installed module do not match.

Control Byte

The control byte is used to determine how the module should operate. The control byte is included in the GSD file.

IMPORTANT

Using your PROFIBUS configuration tool, it is possible to select modules with no configuration data. If you use this type of module, the configuration data for that module will be a default value. (See Appendix B.)

The following table is an example of how User Parameter Data might look with a 1734-OB2E in slot 1, 1734-IB4 in slot 2, and 1734-OE2C in slot 3. All modules in this example use Configuration Data.

Check_Configuration

After the set_parameter service, the master sends a check_configuration service to the adapter. This service causes the adapter to check its default configuration (determined at powerup), against the actual configuration specified in the master configuration. If the actual configuration does not match the default configuration, the master will respond to the Check_configuration service with a negative acknowledgement, which causes the master to set the Configuration fault bit in the Slave_diagnostic service.

Note: Data exchange is not possible as long as the actual configuration does not match the default configuration.

The POINT I/O PROFIBUS adapter is a modular slave, which means that the size of the I/O block is flexible and not tied to a specific block length. Each I/O module is represented by an identifier byte. This byte defines the input- and/or output data length as well as the data consistency of the I/O data.

The identifier bytes for all POINT I/O modules are contained in the GSD file and are automatically extracted by the configuration tool when you add the modules to your configuration.

The identifier byte is described below. More information is contained in the PROFIBUS-DP standard (DIN 19245-3).

This service permits the master to read out the Identifier bytes for the actual adapter configuration. (Refer to the previous section for the format of the identifier byte.)

The table below shows an example of how the identifier bytes from a Get_configuration response would look like when you have the following modules in the backplane: slot 1 = 1734-OB4E; slot 2 = 1734-IE2C; slot 3 = 1734-OE2C; and slot 4 = 1734-IA2.

3 10h 1734-IA2; 1 byte in, consistency over byte

Global_Command

Sync/Freeze

In addition to the cyclic data exchange, which is executed automatically by the master, the master can send control commands to a single slave, a group of slaves or all slaves simultaneously. These control commands are transmitted as multicast commands and permit use of sync and freeze modes for event-controlled synchronization of the slaves.

The POINT I/O adapter begins sync mode when it receives a sync command from the assigned master. The output channels of all I/O modules are then frozen in their current state. During subsequent user data transmissions, the output data are stored at the adapter, but the output states remain unchanged. The stored output data is not sent to the outputs until the sync command is receivied. Sync mode is concluded with the unsync command.

Similarly, a freeze control command causes the adapter to assume freeze mode. In this operating mode, the states of the input channels of all I/O modules are frozen at the current value. Input data is not updated again until the master sends the next freeze command. Freeze is concluded with the unfreeze command.

Publication 1734-UM005B-EN-P - June 2001

Communication and I/O Table Mapping 4-9

Operating States

The general system behavior is determined by the operating status of the master. The 3 main states are:

• Stop - No data transmission occurs between the master and the

slaves.

• Operate - The master is in the data transfer phase. In cyclic data

communication , inputs of the slaves are read, and output information is written to the slaves.

• Clear - The master reads the information of the slaves and sets

the outputs to an idle state. (Refer to “Configure Idle Action Value for Your Output Modules,” page 3-11.)

Data_Exchange

After correct set_parameter and check_configuration services, the master automatically starts exchanging data with the adapter by means of the data_exchange service.

Slave_Diag

The adapter may notify the master of its current state by means of the slave_diag service. The information received from this service request can be divided into 3 parts:

• Standard diagnostic information according to the PROFIBUS

standard DIN 19245-3

• Module related diagnostics indicates which I/O module has

diagnostic events pending.

• Channel related diagnostics, give more detailed information of

the actual cause of the event (wire-break, overcurrent, etc.).

Grouping Modules for Memory Management

You can install up to 8 of the same type of module (identical product code) next to each other and use only one word of input or output memory. The module requirements are:

• the modules must be next to each other

• the modules must be members of the same module family

• must total 8 channels or less

• the modules will share the same configuration data.

You select the option 4, bit stuffing module, in the hardware catalog in the configuration tool.

1. Select the 1734-OB2E (hardware type 1) from the hardware catalog.

The adapter will open a byte and store the first 1734-OB2E module there.

2. Select the 1734-OB2E (hardware type 4 - grouped) from the hardware catalog.

The adapter will store the second 1734-OB2E in the opened byte.

3. Select the 1734-OB2E (hardware type 4 - grouped) from the hardware catalog.

The adapter will store the third 1734-OB2E in the opened byte.

4. Select the 1734-OB2E (hardware type 4 - grouped) from the hardware catalog.

The adapter will store the fourth 1734-OB2E in the opened byte.

Note that the grouped modules will share the same configuration data as the first module in the group. If the first module has no configuration data, the other three modules will have no configuration data.

In this chapter, you learned about communication and I/O table mapping. Move to chapter 5 for troubleshooting.

How to Configure the Adapter for Grouped Mode 5-2

Configuration Example 5-3

Chapter Summary and What’s Next 5-4

In order to use master memory most effectively, and reduce data transfer between the POINT I/O adapter and the master, you can group several modules in a single byte.

To configure the adapter for grouped mode you must:

1. insert modules adjacent to each other

2. Modules must be in the same module family

Groups may exist as follows:

• 1734-IB2, 1734-IV2, 1734-IM2 and 1734-IA2 can be grouped

together

• 1734-IB4 and 1734-IV4 can be grouped together

• 1734-OW2, 1734-OA2 and 1734-OX2 can be grouped together

The following modules cannot be grouped with any other module type:

• 1734-OB2E can only be grouped with 1734-OB2E modules

• 1734-OB4E can only be grouped with 1734-OB4E modules

3. A maximum of 8 channels (1 byte) per group

4. Modules in a single byte will have the configuration of the first

module in the group. (Exception: Extended diagnostics can be enabled/disabled on a per module basis.)

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

5-2 Grouped Mode

How to Configure the Adapter for Grouped Mode

You can select the following modules in the configuration tool:

1. Module without configuration data (e.g. 1734-OB2E/no config)

2. Module with configuration data (e.g. 1734-OB2E/with config)

3. Empty slot module (e.g. 1734-OB2E/empty slot)

4. Grouped module (e.g. 1734-OB2E/grouped)

5. Grouped empty slot module (e.g. 1734-OB2E/grouped empty

slot)

By combining these modules, groups can be created in 3 different ways:

1. A group of modules with configuration data

2. A group of modules without configuration data (default

configuration will be used for all modules in the group)

3. A group of empty slot modules

The following example illustrates how to group modules in a single byte.

1. Select the 1734-OB2E (hardware type 1) from the hardware catalog.

The adapter will open a byte and store the first 1734-OB2E module there.

Publication 1734-UM005B-EN-P - June 2001

If more modules are to be grouped, a new byte has to be opened (repeat steps 1 through 4).

Grouped Mode 5-3

Note that the grouped modules will share the same configuration data as the first module in the group. If the first module has no configuration data, the other modules in the group will have no configuration data.

The configuration for the above example will look like the following in the configuration tool.
