1.2 Deployment Checklist

This is a list of the steps you must complete to install your ProTalk module. We recommend that you read this section completely before you begin the installation.

During this procedure, you will install the module in the rack with the processor, set up a PROFIBUS Master, connect one or more PROFIBUS slave devices, and then configure the processor with information about the PROFIBUS network. The example programs you will be configuring are designed to demonstrate that the module and the processor are correctly configured and communicating with each other over the backplane. After this initial installation, you may need to perform additional steps to configure the application for your specific needs.

You must complete these steps in the following order, otherwise the installation may not be successful.

1 Install the ProSoft Configuration Builder software on your PC

Important: Earlier versions of ProSoft Configuration Builder do not support the Hot Standby (HSBY) feature on the PTQ-PDPMV1 module. To make full use of the HSBY feature, please download the latest version of ProSoft Configuration Builder and review the readme files from the ProSoft Technology website at www.prosoft-technology.com/pcb.

2 Install the ProTalk module in the rack 3 Configure the module 4 Configure the PROFIBUS Master and slaves 5 Export the processor files 6 Configure the processor 7 Verify communication between the processor and the module

1.4.1 Installing the ProTalk Module in the Quantum Rack

1 Place the module in the Quantum rack. The ProTalk module must be placed

in the same rack as the processor.

2 Tilt the module at a 45 angle and align the pegs at the top of the module with

the slots on the backplane.

3 Push the module into place until it seats firmly in the backplane.

CAUTION: The PTQ module is hot-swappable, meaning that you can install and remove it while the rack is powered up. You should not assume that this is the case for all types of modules unless the user manual for the product explicitly states that the module is hot-swappable. Failure to observe this precaution could result in damage to the module and any equipment connected to it.

HSBY Note: For HSBY setup, repeat the above procedures for the Primary and Standby

modules.

1.4.2 Connecting to the ProTalk Configuration/Debug Port

Note: The module has a serial port as well as an Ethernet port. The first time you connect to the

module to configure it, you can connect to the module’s serial port using the supplied null-modem cable, because the module’s default Ethernet settings may not match your network.

HSBY Note: For HSBY units the Ethernet connection must be applied. This connection is used as a backup to ping status messages over the PROFIBUS network. It is also used for DPV1 remote (passive) Master buffer update during switchover.

PC to Ethernet Port Connection

Important: The PTQ-PDPMV1 module is equipped to use an Ethernet connection using the

following defaults:

My_ip: 192.168.0.100 Netmask: 255.255.255.0 Gateway: 192.168.0.1

HSBY Note: For HSBY units the remote (passive) Master module Ethernet connection is always Primary IP plus 1. For example, Primary IP = 192.168.0.100, Standby module IP =

192.168.0.101. This setting is not configurable: the module's firmware automatically sets the IP address of the remote (passive) Master.

If you cannot use these defaults for your connection, you must change them using ProSoft Configuration Builder and then download the new values to the PTQ-PDPMV1 module, either through a serial cable, or by using a Compact Flash (CF) writer. If you need to change the Ethernet addresses, use ProSoft Configuration Builder to change the values in the WATTCP file.

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

2.1 Configuring the Module with ProSoft Configuration Builder

In this step of the setup process, you will use ProSoft Configuration Builder to configure the parameters that affect the interface between the PTQ module and the processor (Quantum or Unity). These parameters indicate:

 The physical position of the module in the rack.

HSBY Note: For HSBY units, the local (active) and passive modules must be placed in the same rack location in both racks.

 The starting memory address in the processor's State RAM for the module's

input and output data images. For the purpose of this example, we use a starting address of 1000 for the input image and 3000 for the output image.

To begin, verify that the processor is correctly positioned in the rack, and is powered up. Connect your PC to the PTQ-PDPMV1 module using the supplied Null Modem serial cable, as shown in the following illustration.

Note: The serial port should only be used for initial configuration of the Ethernet port through ProSoft Configuration Builder.

After the Ethernet settings are correctly configured, only the Ethernet port should be used for configuration changes, diagnostics, and PROFIBUS monitoring.

the configuration to match the values in the following illustration. To change a value, select the parameter to modify in the left pane, and then type the new value in the edit field in the right pane. If you are not sure what to enter here, use the default values.

Note: The values you enter for the purpose of this example configuration are used by the sample program that you will download to the processor later in this section. You may need to change these values as you implement your production system. Use the following chapters for your Quantum or Unity configuration software, or the online help system, for detailed information on each of the parameters associated with the module.

Page 26 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

Slot Number

The Slot Number is the physical location of the module in the rack. The example here assumes a basic configuration with a power supply occupying the first slot, the processor occupying the next two slots, and the PTQ-PDPMV1 module occupying the fourth slot. In this case the module would be in slot 4.

Note: If the module is not placed in the slot number specified, the module will not operate, and the CFG ERR light will illuminate. You must specify the actual slot number for the module in the module configuration file.

Input Data Size

Number of PROFIBUS input point words. Leave this setting at its default value of 768 words.

Output Data Size

Number of PROFIBUS output point words. Leave this setting at its default value of 768 words.

Start Registers

ProSoft Technology, Inc. Page 27 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

The Input Start Register address refers to the 3x (%IW) location in the processor’s State RAM and the Output Start Register refers to the 4x (%MW) location of State RAM. You can view State RAM information in Unity XL Pro.

A common mistake is to assume that because the Input Start Register parameter starts at address 301000, then the PROFIBUS data associated with the slaves will also start at the same register. As the diagram above shows, the Input PROFIBUS Data would start at address 301223 for this example.

Important: The Input and Output Start Register parameters define the start registers for the input and output blocks that are transferred between the processor and the module. The PROFIBUS I/O associated to the slaves is part of these blocks. Refer to PTQ Input and Output Data Blocks (page

251) for a description. Each block contains status, PROFIBUS data, and Mailbox/Slave diagnostics, if chosen.

Input Start Register

The Input Start Register address refers to the 3x (%IW) location in the processor’s State RAM. You can view State RAM information in Unity XL Pro.

Output Start Register

The Output Start Register refers to the 4x (%MW) location of State RAM. You can view State RAM information in Unity XL Pro.

Input Byte Swap

Swap bytes in input image (YES or NO). The default value is NO. This is a user-configured flag to indicate if input data is swapped before being

placed in the input image for the controller. If the parameter is set to 0, no swapping occurs. If it is not 0, then bytes are swapped.

For more information on byte swapping, please refer to Status Data in the Input Data Block (page 256).

Output Byte Swap

Swap bytes in output image (YES or NO). The default value is NO. This is a user-configured flag to indicate if output data is swapped after being

received from the controller. If the parameter is set to 0, no swapping occurs. If it is not 0, then bytes are swapped.

Mailbox Messaging

Use mailbox messaging over the backplane (Y or N with Y=default). For this example, leave the setting at its default. For more information on the

effect of this setting, please refer to Mailbox Messaging (page 151).

Page 28 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

Slave Diagnostics

Get slave diagnostic data (Y/N with N=default). For this example, leave the setting at its default. If you change the default value of this setting and the previous one (Mailbox

Messaging) from their default values, the layout of the I/O blocks changes. The following diagram shows the layout of the I/O blocks when Mailbox

Messaging is set to YES (the default value), and Get Slave Diagnostic Data is set to YES.

ProSoft Technology, Inc. Page 29 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

The following diagram shows the layout of the I/O blocks if Mailbox Messaging is set to NO, and Slave Diagnostics to YES.

The following diagram shows the layout of the I/O blocks if Mailbox Messaging is set to NO, and Slave Diagnostics to NO.

In ProSoft Configuration Builder, the Show Concept Map and Show Unity Map commands show the layout of the entire input and output backplane blocks.

Refer to Input and Output Data Block Format (page 251) for detailed information on the contents of these blocks, and a discussion of how various configuration options change the layout of these blocks.

Page 30 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

Duplex/Speed Code

0=Auto-negotiate 1=10 MB / half-duplex 2=10 MB / full-duplex 3=100 MB / half-duplex 4=100 MB / full-duplex

This parameter allows you to set the connection speed manually between 10 Mbps full / half-duplex and 100 Mbps full / half-duplex or to auto-negotiate the baud rate with a hub or switch. The default value is 10 MB / half-duplex.

Non-Transfer Area Register

Note: This configuration option is only available for Hot Standby operation.

If this parameter is set to 0, the PROFIBUS configuration CRC will be derived from the Output Area.

If this parameter is set to a value GREATER THAN 0, the PROFIBUS configuration CRC will be derived from the specified Non-Transfer Area register.

You can specify a register outside the Output Area to derive the CRC value for the PROFIBUS configuration. This parameter allows you to modify the PROFIBUS DP network configuration without stopping the system.

This data area uses 4 words, and must be located in the 4x memory area. The module will attempt to read this data asynchronously from the non-transfer data area. When new values are received, they are placed in the normal area used by the program. Because this operation is asynchronous to the scan, it may take 2 or more scans for the data to update.

Completing the Example Configuration

When you have finished updating the values, click OK to save your settings and return to the ProSoft Configuration Builder window.

At this time, you may wish to rename the Default Project and Default Location folders in the tree view. To rename an object:

1 Select the object, and then click the right mouse button to open a shortcut

menu. From the shortcut menu, choose RENAME.

2 Type the name to assign to the object. 3 Click away from the object to save the new name.

The next task is to update the module's Ethernet settings. This allows you to connect from your computer to the module using an Ethernet cable rather than a serial cable.

6 Double click the SLAVE icon to view the Slave properties.

In particular, note the following settings:

o Automatic PROFIBUS Address Assignment:

ProSoft Configuration Builder automatically assigns a PROFIBUS address to each new slave. The address assignment begins at address 3, and is incremented by 1 for each new slave added to the network. You can change the address in the COMMON tab of the Slave Properties dialog box.

o Automatic Input/Output Address Assignment:

For each new slave added to the PROFIBUS network, ProSoft Configuration Builder automatically converts the input/output byte addresses to word input/output addresses for the State RAM in the processor.

7 Repeat steps 2 through 6 for all slaves you intend to place on the network. 8 When you are finished adding slaves, open the PROJECT menu and choose

EXIT to return to the Master Setup dialog box.

ProSoft Technology, Inc. Page 39 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

Using The Autoscan Feature The concept of Automatic network scanning means that the user can instruct the

Bus Configuration window to automatically gather information about slaves that

are connected to the network. When the scan is completed the user can adopt the detected slaves to the bus configuration and download to the Master.

This is a quick way to get a network up and running. However, one should be aware that it is not guaranteed that any particular slave will enter data exchange since the user parameter data might not match. This is especially obvious if no associated GSD-file is found during the network scan, this means that no user parameter data would be sent to the slave.

NETWORK SCAN is selectable from the Online menu as well as from the drop- down menu for the MASTER icon.

Page 40 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

When the download is completed, the PROFIBUS Master Configuration window will initialize the Master to operate as a Class 2 Master only. In this mode it is possible to initialize the Master even if the database does not contain any slaves.

After successful initialization, the PROFIBUS Master Configuration window will issue the following mailboxes in order to gather information about the connected slaves:

1 1. Send FB_APPL_GET_LIVE_LIST in order to detect connected slaves, 2 2. Send FB_APPL_GET_SLAVE_DIAG (external request) to all devices

identified as slaves according to the Live list.

3 3. Send FB_APPL_GET_SLAVE_CONFIG to all devices identified as slaves

according to the Live list.

When the information is collected the PROFIBUS Master Configuration window will find a matching GSD-file and extract information from it. Refer to the flowchart below for this sequence:

GSD Selection Algorithm

If two or more matching GSD-files are found, the first one found should be selected. The other compatible files should be stored so that the user can select one of them instead. If the user selects another GSD-file, the PROFIBUS Master Configuration window will run through the Module Selection Algorithm (described below) again.

ProSoft Technology, Inc. Page 41 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

Module Selection Algorithm

The algorithm used to find modules in the GSD based on the Identifier byte(s) is as follows:

Select the module that matches the largest number of Identifier bytes. If the GSD contains two or more modules with the exact set of Identifier bytes, use the first module found.

Example: If a slave responds with identifier bytes: 0x11, 0x21, 0x31 and that the associated

GSD-file contains five modules: “A” = 0x11, “B” = 0x21, “C” = 0x31, “AB” = 0x11, 0x21 and “BC” = 0x21, 0x31. The PROFIBUS Master Configuration window will then select modules "AB" and "C".

Note: If no matching module is found in the GSD, The PROFIBUS Master Configuration window will display the identifier byte(s) instead.

Network scan window The information extracted from the GSD-file(s) will be displayed in the Network

scan window.

Select

In this column all found slaves will be marked as selected by default, except for slaves with the special address 126 (refer to the next section that describes the Address column). Only selected slaves will be added to the PROFIBUS Master

Configuration when the ADOPT SELECTED SLAVES button is clicked.

Address

In this column the node address of the slaves will be displayed. Found slaves should be listed in ascending order according to their node addresses.

Page 42 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

Special address 126 -Set Slave address:

If a slave with node address 126 is detected during the network scan, the PROFIBUS Master Configuration window will display the address in red color. It will not be possible for the user to adopt the slave to the configuration since it is not allowed to exchange data with devices having this address. The check box in the Select column will be grayed out.

To be able to adopt a slave with address 126 the user must first assign a valid address by clicking the icon next to the node address. By doing so the Set Slave Address dialog box is started.

Note that the Old slave address is preset to a value of 126 that is not editable (grayed out).

ProSoft Technology, Inc. Page 43 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

If the Slave is in the configuration already then it will not affect the addressing.

Example:

After scanning, the network finds these other slaves: 2, 6, 25, and 40 Slaves 2, 6, and 25 are found, but are marked as in the bus configuration (the mapping of the inputs and outputs will not be affected) Slaves 40 is new and could be added and the input/output addressing will be appended to the end as shown on the last screen.

The PROFIBUS Master Configuration window will prevent the user from selecting a New slave address that is already occupied by another device; this includes detected Master stations as well. If the user selects an occupied address, a message similar to the one shown here will open.

When an address has been successfully assigned, the PROFIBUS Master Configuration window will update the Network scan window as shown here. The node address will be updated to the one that the user selected in the Set Slave dialog box. The check box in the Select column will be marked allowing the user to adopt the slave to the configuration.

Slave

In this column the name of the slave as stated in the assigned GSD-file will be displayed. If no matching GSD-file is found the Ident number will be displayed in red color in the drop-down list.

Module

This column shows the name of the module(s) as stated in the assigned GSDfile, which matches the Identifier byte(s) derived from the GetCfg mailbox message. If no GSD-file or no matching module is found the Identifier byte(s) will be displayed in red color. If the configuration for a slave is constructed of several modules, the modules will be listed under each other.

If there is more than one module in the GSD-file that matches the Identifer bytes, the first matching module will be displayed in blue color in a drop-down list. The drop-down list will contain all other matching modules so that the user can select the desired one.

Note: Only modules that have the exact same Identifer bytes as the first matching module will be displayed in the drop-down list.

GSD-file

This column shows the name of the GSD-file that matches the Ident number derived from the SlaveDiag mailbox message. If there are more files with the same Ident number in the device catalog, the first matching GSD-file will be displayed in blue color in a drop-down list.

This could be the case if the device catalog contains two or more brand labeled devices, or GSD-files for two or more languages (for example NICEDEV.GSD and NICEDEV.GSE) exist.

Note: If the user selects another GSD-file, The PROFIBUS Master Configuration window will update the modules for that slave accordingly.

2.3.3 Exporting the Processor Memory Map

The import file (PTQ_PDPMV1.XSY for Unity, or PTQ_PDPMV1.DTY for Concept) that you create in this step uses the information in the Processor Memory Map to build the derived data tags for the slave devices on your PROFIBUS network. These tags allow the program running on the processor to access data within the module.

Page 50 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

To export the processor memory map

1 In the Master Setup dialog box, click SHOW CONCEPT MAP (for processors

configured with Concept software) or click SHOW UNITY MAP (for processors configured with ProSoft Configuration Builder software).

2 This action opens the Memory Map dialog box.

3 On the Memory Map dialog box, click EXPORT PROCESSOR FILES.

Note: For Unity Map, PCB will export the XSY file and XFM files in the same directory if mailbox parameter is chosen. The filenames will match the module name you chose in PCB. For Concept Map, PCB will export .dty file, .txt file and .asc files if mailbox parameter is chosen.

ProSoft Technology, Inc. Page 51 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

4 Name the file and choose a location on your hard drive. The recommended

location is your My Documents folder, and then click SAVE.

5 Click PRINT to print the input and output maps for reference. When you import this memory map file into the processor configuration, it

simplifies the task of establishing communications between the module and the processor. You will have to establish backplane communications using either Concept or Unity XL Pro software.

After you download the configuration to the PTQ-PDPMV1 module, save the .dty and .xsy files to a location on your hard drive (a folder below C:\PCBExportFiles), where you will import them into the processor during the processor configuration steps. These project files greatly reduce the amount of time it would otherwise take to perform the necessary configuration tasks.

If you are using Unity 7.X or later, you will use the PTQ-PDPMV1.xfm and PTQ- PDPMV1.xsy files.

If you are using Unity 2.X to 6.X, you will use the PTQ-PDPMV1_V2.X-6.X.xfm and PTQ-PDPMV1_V2.X-6.X.xsy files.

Refer to Configuring the Processor with Unity Pro (page 59) and Configuring the Processor with Concept (page 101) for detailed instructions on how to configure the processor.

Note: The recommended location for the files is the My Documents folder on your PC. The configuration tool for the processor will use this folder by default.

Calculating Checksums

The checksum (CRC) values are calculated from the PROFIBUS configuration data, and compare the contents of the configuration file in the module with the value reported by the processor. The checksum (CRC) value allows the processor to verify that the configuration file is valid, and has not changed since the last time the configuration file was imported to the processor. Any change to the contents of the configuration file in either location changes the unique numeric (CRC) value for the file.

If the checksum values do not match, the Master stops and indicates a configuration error, and the CFG light illuminates on the module.

1 On the PTQ-PDPMV1 PROFIBUS Master Setup dialog box, click the

CALCULATE CHECKSUMS button.

2 Make a note of the checksum values so that you can enter them later if

prompted.

3 To insert the checksum values in Unity Pro, refer to Updating Checksum

Values: Unity Pro (page 67). To insert the checksum values in Concept, refer to Configuration Validation &

SETCRC Function Block (page 128).

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Module PROFIBUS DP Master Network Interface Module for Quantum User Manual

2.3.4 Downloading the Project to the Module

In order for the module to use the PROFIBUS network settings you configured, you must download (copy) the updated project file from your computer to the module.

Note: The processor (Quantum) must be in "Stop" mode before you download the file to the module. Use the processor’s configuration tool or the softkeys on the processor to stop the processor.

To download the project file

1 In the tree view in ProSoft Configuration Builder, click once to select the PTQ-

PDPMV1 module.

2 Open the PROJECT menu, and then choose MODULE > DOWNLOAD. This

action opens the Download Files dialog box.

3 Choose ETHERNET from the dropdown list, and then click the DOWNLOAD

button. When the download is complete, a dialog box will prompt you to place the processor back into RUN mode.

Note: If you have not yet downloaded the Ethernet Configuration (WATTCP.CFG) file, which contains the customized IP address settings for the module, you have the option on this dialog box to connect using the module’s default IP address (192.168.0.100).

HSBY Note: For HSBY Ethernet downloading (Ethernet recommended), both HSBY modules must be connected to allow PCB to download to both modules. PCB will download to the first Master, and will then prompt you to download the project to the second module Master.

ProSoft Technology, Inc. Page 53 of 306 August 12, 2014

Configuring the Module PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

The module will perform a platform check to read and load its new settings. When the platform check is complete, the status bar in ProSoft Configuration Builder will be updated with the message Module Running.

2.3.5 Backing Up the Project

In this step, you will create a backup copy of your project and configuration files. The backup procedure saves your data for reuse on another machine, or allows you to restore your data in the event of a system failure.

To save your project and configuration files

1 In ProSoft Configuration Builder tree view, click [+] to expand the PTQ-

PDPMV1 tree, and then double-click the PROFIBUS DP icon. This action opens the PROFIBUS Master Setup dialog box.

2 In the PROFIBUS Master Setup dialog box, click the EXPORT MASTER CONFIG

button. This action saves the PROFIBUS network configuration for your module in an XML file. The recommended location for this file is your My Documents folder.

Tip: You can use the XML file created by ProSoft Configuration Builder in this step to simplify the task of configuring additional PROFIBUS network modules. Because its saves the entire network configuration, you can add modules quickly by modifying only the items that are unique for each device, typically the slot number and I/O addresses. To use this saved configuration, open Windows Explorer, navigate to the folder where you saved the Master Configuration XML file, and then drag the file onto the new PROFIBUS DP icon in the ProSoft Configuration Builder tree view.

SAVE AS.

7 Name the project file, and click SAVE. The recommended location for this file

is your My Documents folder.

Note: All PCB project files and module-related files are automatically saved to C:\PCBExportFiles.

A complete backup consists of the project and Master configuration files, plus the GSD configuration files. The default location for the GSD files is C:\Documents

and Settings\All Users\Application Data\ProSoft\GSD (Windows XP / 2000) or C:\My Documents\. To move a project to a different PC, copy the .PPF, .XML,

and .GSD files to the same directory structure on the new machine that they occupied on the old one.

The above method defines a manual approach in creating Quantum processor I/O and Function Block import files. The PCB will also automatically create these files when the PCB project is saved or closed (if the project is not saved then PCB will not export the files).

You can also generate these files manually from PCB. To create the files:

1 Open the PROJECT menu, and select PROJECT > EXPORT FILES. 2 If you are prompted to overwrite files, click YES.

3.1 Importing the Functional Module

To simplify the task of programming the processor when communicating with the PTQ-PDPMV1 module, ProSoft Technology has created a Unity Pro Functional Module type (XFM).

Warning: The Functional Module is intended for new installations of PTQ-PDPMV1. If you have an existing installation, the following procedure will overwrite your settings, and may cause loss of functionality. DO NOT overwrite a working application until you have thoroughly reviewed the following topics.

The Functional Module provides easy access to PROFIBUS slaves' cyclic data

and the PTQ module’s input/output status data. Specific mailbox commands are

provided to perform DPV0/V1 acyclic functions such as Get Live List, Get Slave Diagnostics, and perform Freeze and Sync commands. The Functional Module

exchange file name matches the module name you defined in PCB, with the extension .XFM. This file is created by PCB when you export the processor file from the Show Unity Map dialog box (page 54).

To import the Functional Module

Use the project you created in Unity Pro, and perform all of the following steps. 1 Open the VIEW menu, and then choose FUNCTIONAL VIEW.

Page 60 of 306 ProSoft Technology, Inc. August 12, 2014

3 To view the DFBs, data types and variables associated with the Functional

Module, open the VIEW menu and choose STRUCTURAL VIEW. Notice that all

function blocks have been defined using the ST type language.

To import the variables

Import the PROFIBUS I/O table, found in the .xsy file which was created when the memory map was exported from ProSoft Configuration Builder (PCB) (see Backing Up the Project (page 54)). This file contains all the cyclic input and output variables configured by the PCB Master configuration software. It includes module status data, and may also include slave diagnostic data and mailbox data if these parameters were chosen.

1 In the Project Browser, select VARIABLES & FB INSTANCES, and click the right

mouse button to open a shortcut menu. On the shortcut menu, choose

IMPORT.

2 In the FILES OF TYPE dropdown list, choose DATA EXCHANGE FILE (*.XSY).

At this point, the input and output variables have been imported to the application.

HSBY Note: If the Non-Transfer parameter value is used and it is greater than zero, then the

XSY file will contain the correct CRC for the module.

The value you entered in ProSoft Configuration Builder for the Non-Transfer parameter should also be entered in the non-transfer area of the processor.

For example, if you entered Non-Transfer Area Register = 4000 in ProSoft Configuration Builder:

Page 64 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Processor with Unity Pro PROFIBUS DP Master Network Interface Module for Quantum User Manual

You must enter the same value in this location of the processor memory.

To modify an animation table

Note: An animation table is required to send and receive mailbox messages, monitor State Ram status and read/write IO data.

An animation table is provided with the XFM file, but certain data variables must be added to monitor the status or health of the module.

3.1.1 Updating Checksum Values

The PTQ-PDPMV1 module is almost ready, and the CRC values for the PROFIBUS configuration should match between the module and the processor.

To confirm that both CRCs match

1 From PCB, select the MODULE icon, and then click the right mouse button to

open a shortcut menu.

2 On the shortcut menu, choose DIAGNOSTICS. Wait for ProSoft Configuration

Builder to go online with the module through the serial or Ethernet port.

3 When the module is online, press [?] to display the Main menu. 4 On the Main menu, press [C] to view the module configuration. The following

illustration shows example CRC values for the Module File and the PROFIBUS File.

Note: Because the CRC values are calculated for your unique configuration, the values on your screen will not be the same as the ones in the following illustration.

ProSoft Technology, Inc. Page 67 of 306 August 12, 2014

Configuring the Processor with Unity Pro PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

To calculate checksums

1 On the PDPMV1 PROFIBUS Master Setup dialog box, click the CALCULATE

CHECKSUMS button.

Notice the NEW checksums for the module and PROFIBUS appear.

Note: The module checksum will change when parameters such as 3X or 4X starting address are changed. The PROFIBUS checksum will change if a network parameter is changed.

HSBY Note: For Hot Standby application, if you use the Non-Transfer parameter, the module expects the CRC to be taken from the offset you provided, which must match the offset you entered in the processor program.

The CRC value is provided in the XSY file exported by ProSoft Configuration Builder, as shown in the following illustration.

If the Non-Transfer parameter is set to 0 (not used), the CRC is provided in the PTQPDPMV1HSBY_StatOut area, as shown in the following illustration.

2 If the CRC values do not match, copy the PROFIBUS checksum by

highlighting the text and right-clicking to COPY.

Page 68 of 306 ProSoft Technology, Inc. August 12, 2014

to the rack.

7 When you have finished adding devices, open the FILE menu and choose

SAVE. This action saves the project to the hard drive on your computer.

3.1.3 Configuring the Memory Size for the Processor

Part of the processor configuration process allocates memory to use in the processor to store input and output data from the module. For installations where the processor communicates with only one module, the default memory settings will work without further configuration. The following steps will help you determine the correct memory addresses to assign for more complex installations.

The processor memory maps that you configured in ProSoft Configuration Builder are exported from ProSoft Configuration Builder, and imported into the Unity Pro project. These values are calculated from the starting memory address in the processor's State RAM for the module's input and output data images. Refer to Configuring the Module (page 21) for more information on configuring memory addresses in ProSoft Configuration Builder.

Depending on the complexity of your installation, for example when you are deploying the PTQ-PDPMV1 module in an existing system, you should view the memory configuration for the processor in ProSoft Configuration Builder before you begin to configure memory addresses in Unity Pro.

Some points to keep in mind are:  As the programmer, you must be aware of the memory spaces that are

available when deploying in an existing system, and assign values to the PTQ accordingly.

ProSoft Technology, Inc. Page 71 of 306 August 12, 2014

Configuring the Processor with Unity Pro PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

 Data registers must exceed starting registers. This is in the memory map

page that you printed.

 You must assign the PTQ module to a block of processor memory that is not

being used by any other device.

 You can use this simple formula to find a block of memory to use: If the

module consumes 224 words of status data on input, and we know that it can take up to 768 words of I/O data, the total requirement is 992 words. The module will take a maximum of this %IW value. For convenience, round the number up to 1000 as the amount of memory to assign. A value of 5000 for %MW and %IW is a safe starting point.

 It is not possible to determine if the memory values are correct before

building the project. If the build throws an error about memory addresses, go back to ProSoft Configuration Builder and change the input and output properties for the module, then re-import the memory map and try again.

To view memory usage in the processor

1 Start Unity Pro. 2 In the Project Browser, expand the Configuration tree, and then double-click

the LOCAL BUS object.

3 In the LOCAL BUS window, double-click the processor. This action opens a

tabbed window with information about the processor.

4 Click the CONFIGURATION tab. This tab describes the processor's memory

configuration.

project is transferred, Unity Pro reports its process in a PROGRESS dialog box, with details appearing in a pane at the bottom of the window.

When the transfer is complete, place the processor in RUN mode. The processor will start scanning your process logic application.

3.1.6 Verifying Communication between the Processor and the Module

In this step, you will verify that the processor and the PTQ module are communicating with each other over the backplane. The sample project includes an animation table called MailBox Commands. When the processor and the PTQ module are communicating, the values in this animation table are updated in real time.

To verify communication between the processor and the module

1 Place the processor in RUN mode, if you have not already done so. 2 In the Unity Pro project browser pane, click [+] to open the Animation Tables

tree, and then double-click MAIN TABLE.

3 In the Main:Table, you will see all mailboxes, including Get Live List, Get

Diagnostics, and so on.

4 You must include {ModuleName}_StatIn, {ModuleName}_MailIn and

{ModuleName}_DataIn, using the same procedure for the Output {ModuleName}_StatOut, {ModuleName}_MailOut and {ModuleName}_DataOut.

3.2 Function Blocks Operation Overview

Function blocks define software components or modules that perform a specific function. Each function block has its own, pre-defined set of inputs and outputs.

The function blocks provided with the PTQ-PDPMV1 module contain the logic to handle PROFIBUS acyclic mailbox messages and alarms. They transfer data between the main output/input mailbox arrays and the corresponding slave devices.

The PTQ-PDPMV1 module is ready to receive a mailbox message from the processor when all function blocks have been called in the main program, which is provided in the sample.

ProSoft Technology, Inc. Page 79 of 306 August 12, 2014

Configuring the Processor with Unity Pro PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

MailOut[0] = StatIn.MailBoxData_LastOutMailboxMessageID

Each mailbox data structure is implemented through variables that are divided into Out and In data structures, where:

Out = values copied from the processor to the module In = values copied from the module to the processor

Each Out data structure contains a Cmd bit. After the Cmd bit is toggled, the logic will increment the mailbox ID (output) to send the mailbox request to the module.

The following illustration shows the interface for the SetOperatingMode mailbox:

The following condition indicates that the module has a mailbox response to be sent to the processor. Therefore, the function block implementation will handle the block by copying the response data to the appropriate mailbox data structure.

Page 80 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Processor with Unity Pro PROFIBUS DP Master Network Interface Module for Quantum User Manual

StatOut.ModuleStatus_LastinMailBoxMessageID <> StatIn.MailBoxData_CurrentInMailboxControlIndex

The module will increment StatIn.MailBoxData_CurrentAlarmControlIndex when the module contains alarms to be sent to the processor. The function block implementation will then copy the alarm to the appropriate data structure. The function block implementation uses the following expression to verify if any alarms are available:

StatOut.ModuleStatus_LastAlarmControlindex <> StatIn.MailBoxData_CurrentAlarmControlIndex

After the alarm is copied, the logic then updates the alarm index for handshaking purposes:

StatOut.ModuleStatus_LastAlarmControlindex := StatIn.MailBoxData_CurrentAlarmControlIndex

Please refer to Mailbox Messaging (page 151) for further information about each mailbox parameter.

The following section provides examples of data structure groupings.

3.3 Derived Function Blocks Overview

The Unity Pro programming language for Schneider Electric Automation Quantum processors supports user-defined function blocks (DFB). The user function block types (Derived Function Blocks) are developed by the user using one or more languages (according to the number of sections). These languages are:

 Ladder language  Structured Text language  Instruction List language  Functional block language FBD

A DFB type can have one or more instances where each instance is referenced by a name (symbol), and possesses DFB data types.

Derived Function blocks defined by Unity Pro software are entities containing:

 Input and output variables acting as an interface with the application  A processing algorithm that operates input variables and completes the

output variables

 Private and public internal variables operated by the processing algorithm

3.3.1 Using the Derived Function Blocks

To simplify programming procedures, ProSoft Technology has included a Unity Pro XFM Functional Module used for communication with the PTQ-PDPMV1

module. The Functional Module provides easy access to the Master’s cyclic and

acyclic data. Specific mailbox acyclic commands are also provided to perform functions such as Get Live List and Get Slave Diagnostics, and to perform Freeze and Sync commands, and others.

Note: It is not intended to include in-depth programming information in this reference manual. You should, therefore, be familiar with IEC Function Block programming and Unity Pro programming language.

Page 82 of 306 ProSoft Technology, Inc. August 12, 2014

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Processor with Unity Pro PROFIBUS DP Master Network Interface Module for Quantum User Manual

The PTQ_PDPMV1_Sample Functional Module supports input and output variables used for PTQ status, acyclic mailbox and slave cyclic I/O data. All input information is located in the <Inputs>: StatIn, MailIn and DataIn area (data delivered to the Unity processor) and all output information is located in the <input/output>: StatOut, MailOut, and DataOut (data sent to the PTQ module). You can access the supported mailboxes in the provided table.

Every mailbox has its own function block that has a unique "Impl" ST derived FB type file.

The following illustration shows part of the function block implementation (structured text code) that performs the mailbox request after the command register is triggered by the processor application. For example, the

SetOperatingMode command is executed when the Out (SetOperate,SetStop,SetClear).Cmd bit is true.

This bit is accessed and controlled in a tag in the provided table.

Note: Refer to Special Function Mailbox Messaging Commands (page 153) for more information about Mailbox Commands.

ProSoft Technology, Inc. Page 83 of 306 August 12, 2014

Configuring the Processor with Unity Pro PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

Mailbox data values are pre-defined for the specific mailbox command.

The first statement represents the Message Information of the command (4002h) Set Operating Mode (see specific mailbox command).

Note: The information is byte swapped for PTQ Master module (Motorola big-endian format).

The remaining values [2] to [7] set the Command, Data Size, Frame Count, Frame Number, Offset High and Low byte header information. Again, these values are pre-defined and controlled by the FB.

Most mailbox commands have response information. Refer to Mailbox Messaging (page 151) for more information. The response information will be

written to the area of the SetOperatingMode mailbox area. This information can be read after the mailbox is received and confirmed by the ID information contained in the CurrentMailboxControlIndex value.

When this statement is true and the Set Operating Command was executed the following code will be executed:

The appropriate return value(s) for Set Operating Mode can now be read or accessed in the In.Mode, ConfRequired and FaultInformation values.

Each mailbox command can be executed and responded to using similar procedures as outlined above.

3.4 Using Mailbox Function Blocks

Function blocks define software components or modules that perform a specific function. Each function block has its own, pre-defined set of inputs and outputs.

The function blocks provided with the PTQ-PDPMV1 module contain the logic to handle acyclic mailbox messages and alarms. They transfer data between the main output/input mailbox arrays and the corresponding slave devices.

3.4.1 Overview

The mailbox function blocks build mailbox requests to the module and read the mailbox response from the module. These mailbox function blocks are optional, meaning that the project will update PROFIBUS data and status information even if no function blocks are used.

3.4.3 Trigger Bytes

Mailbox requests are initiated by "triggers" (bytes) that are defined as input/output pins. A mailbox request is initiated after the application moves a value of 1 to the appropriate trigger byte.

Only one mailbox function may be active at any given time. Therefore, in order for a mailbox request to be carried out, the value of all mailbox triggers in your application must be equal to 0 at the time the request is made. If you are using more than one mailbox function block, add program code to guarantee that this condition is satisfied.

The processor will only allow a new mailbox request to be sent out after it has received confirmation that the previous mailbox request was acknowledged by the module. The processor determines this condition by checking the status of all trigger bytes (0=OK). This procedure also prevents more than one mailbox request from being sent out during a single PLC scan.

The following table shows the trigger bytes used for each mailbox function block:

ProSoft Technology, Inc. Page 87 of 306 August 12, 2014

Configuring the Processor with Unity Pro PTQ-PDPMV1 ♦ Quantum Platform

Value

Description

OK to send new mailbox request. The last mailbox request was already acknowledged by the module.

Mailbox request to be performed. The Quantum program should make sure that the required conditions are satisfied (as previously discussed) before moving a value of 1 to the trigger register. The function block will then build the mailbox request by copying all mailbox input parameters to the mailbox output variable that is transferred to the module through the backplane. Then the function block will automatically change the trigger’s value to 2.

Processor has performed the mailbox request and is waiting for the acknowledgment from the module. The acknowledgment informs that the module has received the request (the actual mailbox response is actually sent later). After the acknowledgment is received, the function block will reset the trigger’s value back to 0.

User Manual PROFIBUS DP Master Network Interface Module for Quantum

The Get Alarm function block does not require a trigger because this mailbox is initiated from the module. Refer to Alarm Indication (page 170) for more information.

The trigger byte is a variable that can assume different states as follows:

3.4.4 Specific Input Pins

Each function block has input pins specifically for each mailbox. For example, in order to send a Get Diagnostics mailbox, the application must set the PROFIBUS slave address input pin. The processor program must configure the input pins before performing the mailbox request by moving a value of 1 to the mailbox trigger.

3.4.5 Specific Output Pins

Each function block contains output pins that are updated after the mailbox response is received by the processor. For example, the Get Diagnostics function block has an ExtendedDiagData output pin that stores the diagnostic information received from the slave.

Example

If the Set Operating Mode mailbox function block is used as follows:

3.5 Mailbox Overview

This section provides a brief description on how to use each mailbox function block. Refer to Mailbox Messaging (page 151) for detailed information about each mailbox parameter.

3.5.1 Acyclic Read Mailbox

Function Block: ACYCREAD Trigger Byte: Acyclicread Description: The ACYCREAD mailbox is used to perform an Acyclic Read

request to a PROFIBUS slave device. The input pins SlaveAddress (PROFIBUS slave address), SlotNumber (slot number), IndexIn (index number), and LengthIn (length - number of bytes associated to acyclic read operation) must be configured before triggering the mailbox request. The acyclic read response data is copied to the ReadData output pin. The status information is available in the output pins (ErrorCode, ErrorDecode, ExtendedFaultInfo, and FaultInformation).

The following illustration shows a sample instance of the Acyclic Read mailbox function block:

ProSoft Technology, Inc. Page 91 of 306 August 12, 2014

Configuring the Processor with Unity Pro PTQ-PDPMV1 ♦ Quantum Platform User Manual PROFIBUS DP Master Network Interface Module for Quantum

3.5.2 Acyclic Write Mailbox

Function Block: ACYCLWRITE Trigger Byte: Acyclicwrite Description: The ACYCLWRITE function block is used to perform an Acyclic

Write request to a PROFIBUS slave device. The input pins SlaveAddress (PROFIBUS slave address), SlotNumber (slot number), IndexIn (index number) and LengthIn (length - number of bytes associated to acyclic read operation) must be configured before triggering the mailbox request. The actual data to be written to the PROFIBUS slave should be associated to the WriteData input pin. The status information is available at the output pins (ErrorCode, ErrorDecode, ExtendedFaultInfo and FaultInformation).

The following illustration shows a sample instance of the Acyclic Write mailbox function.

PTQ-PDPMV1 ♦ Quantum Platform Configuring the Processor with Unity Pro PROFIBUS DP Master Network Interface Module for Quantum User Manual

3.5.3 Alarm Mailbox

Function Block: GETALARMS Trigger Byte: The GETALARMS function block does not require a trigger

because this mailbox is initiated from the module. Description: The GETALARMS mailbox is used to read the alarm mailbox

messages sent by the module. The module will automatically generate the alarm mailboxes after it receives the alarm message from the PROFIBUS slave.

The last alarm received is copied at the LastAlarm output pin. This is a data structure that contains all alarm information:

This function block also keeps track of the last 100 alarms through the HistAlarm output pin.

For example, if the module receives 100 alarms (first alarm - Sequence Number = 1, second alarm - Sequence Number = 2, and so on), after alarm #100 is received, the processor application could refer to these alarms stored at the following output pins:

Last Alarm - Alarm #100 HistAlarm[1] - Alarm # 99 HistAlarm[2] - Alarm # 98 HistAlarm[3] - Alarm # 97 HistAlarm[4] - Alarm # 96 HistAlarm[5] - Alarm # 95 HistAlarm[6] - Alarm # 94 HistAlarm[7] - Alarm # 93 HistAlarm[8] - Alarm # 92 HistAlarm[9] - Alarm # 91 HistAlarm[10] - Alarm #90

If the HistoricAlarm buffer is full and it receives a new alarm, then the oldest alarm in the queue will be deleted to reserve space for the new alarm.

The AlarmCount output pin is incremented every time the alarm mailbox is received. This register will roll over at 30000. The processor application can keep track of this register to determine when the processor has received a new alarm mailbox message from the module.

3.5.5 GetDiagnostics Mailbox

Function Block: GETDIAGNOSTICS Trigger Byte: GetDiagnostics Description: The GETDIAGNOSTICS function block can be used to read the

diagnostics from any PROFIBUS slave connected to the PTQ-PDPMV1 module. The slave address must be set at the SlaveAddress input pin. The diagnostics data is copied at the ExtendedDiagData output pin. The number of bytes of the diagnostics message is stored at the ByteCount output pin (status+identification+extended diagnostics). The ExtendedFaultInfo and FaultInformation output pins can be used for status information. The Master address is stored at the MasterAddress output pin.

3.5.6 GetLiveList Mailbox

Function Block: GETLIVE Trigger Byte: GetList Description: The GETLIVE function block can be used to read the live list from

the module containing the status of each device at the PROFIBUS network. The live list is stored at the StationStatus output pin. The live list data is an array of bytes stored as follows:

StationStatus [0] - status of device configured with PROFIBUS address 0 StationStatus [1] - status of device configured with PROFIBUS address 1 StationStatus [2] - status of device configured with PROFIBUS address 2 StationStatus [3] - status of device configured with PROFIBUS address 3 StationStatus [4] - status of device configured with PROFIBUS address 4
