Battery Life Advisory

The MVI46, MVI56, MVI56E, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to backup the real-time clock and CMOS. The battery should last for the life of the module. The module must be powered for approximately twenty hours before the battery becomes fully charged. After it is fully charged, the battery provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user replaceable.

1.4 Setting Jumpers

The Setup Jumper acts as "write protection" for the module’s flash memory. In "write protected" mode, the Setup pins are not connected, and the module’s firmware cannot be overwritten. Do not jumper the Setup pins together unless you are directed to do so by ProSoft Technical Support.

The following illustration shows the MVI46-PDPMV1 jumper configuration.

Note: If you are installing the module in a remote rack, you may prefer to leave the Setup pins jumpered. That way, you can update the module’s firmware without requiring physical access to the module.

2.3.1 Installing the GSD Files

ProSoft Configuration Builder (PCB) uses PROFIBUS slave device definition files (GSD files) to obtain basic configuration information about the PROFIBUS slaves you add to the network. The GSD configuration files identify the slave’s capabilities so that the MVI46-PDPMV1 can communicate with it correctly. Slave device manufacturers provide the GSD files for the equipment they make. Slave device files sometimes come in various languages. When a manufacturer provides slave device files in several languages, it is a common practice to use the third letter of the file extension to indicate the language used in the file. For instance:

.GSD is the most commonly used file extension and will usually be in either English or German

.GSE will usually be in English

.GSS will usually be in Spanish

.GSF will usually be in French

other combinations may also be seen, as well as other languages using the letters indicated above

Follow these steps to install the GSD file or files for your slave device or devices.

Page 30 of 160 ProSoft Technology, Inc. March 25, 2011

MVI46-PDPMV1 ♦ SLC Platform Configuring the MVI46-PDPMV1 Module PROFIBUS DPV1 Master User Manual

Tip: GSD configuration files for popular PROFIBUS slaves and ProSoft Technology solutions are included with PCB. Before installing GSD files, browse the list of available slaves in the Tree View window to see if GSD files for your slave are already installed. GSD files are often both model number specific as well as model revision specific. Just because you may have an older GSD file from a manufacturer for the particular make and model of your slave device does not guarantee it will work for a newer revision of that device. Be sure you obtain from the device manufacturer the correct GSD file or files for your PROFIBUS slave or slaves.

To install GSD files manually

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

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

2.3.2 Configuring the PROFIBUS Slaves

There are two essential steps to configuring a slave: 1 Add the slave in ProSoft Configuration Builder (PCB) as a device connected

to the PROFIBUS Master, specifying the slave address and any necessary input and output configuration. Download the PROFIBUS Master configuration to the MVI46-PDPMV1 module.

2 Configure the slave (using PCB or the configuration tool supplied by the

manufacturer, for some PROFIBUS slaves). Verify that the slave address configured in the slave module matches the slave address configured in PCB. Download the PROFIBUS Slave configuration to the slave module.

In particular, note the following settings:

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.

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

XIT

to return to the Master Setup dialog box.

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.

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.

MVI46-PDPMV1 ♦ SLC Platform Configuring the MVI46-PDPMV1 Module PROFIBUS DPV1 Master User Manual

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:

ProSoft Technology, Inc. Page 37 of 160 March 25, 2011

Configuring the MVI46-PDPMV1 Module MVI46-PDPMV1 ♦ SLC Platform User Manual PROFIBUS DPV1 Master

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.

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 A

DOPT 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 38 of 160 ProSoft Technology, Inc. March 25, 2011

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).

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

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 Calculating the 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 APP STATUS light illuminates on the module.

1 In the 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.

2.3.4 Printing the Processor Network Memory Map

2.4.1 Checking the PROFIBUS LEDs on the MVI46-PDPMV1

 If all four PROFIBUS LEDs (page 99) are illuminated green, then the

PROFIBUS Master is communicating and exchanging data with all configured PROFIBUS slaves.

 If the COM STAT LED is green and flashing, the PROFIBUS Master is

communicating and exchanging data with at least one of the configured slaves.

 If the COM STAT LED is red, there is a communication or configuration error.  If the COM STAT LED is off, the PROFIBUS Master is not communicating

with any slaves. The most likely reason is that the slaves are not correctly configured.

 After restarting the MVI46-PDPMV1 Master and the PROFIBUS slave, look at

the PROFIBUS cable connection. If all the PROFIBUS LEDs on the MVI46PDPMV1 are illuminated green, then the Master is communicating successfully with all slaves.

communicating correctly, the operation state will be C0 (hex).

5 Note the values in SLAVE CFG LIST, TRANSFER LIST and SLAVE DIAG

LIST. If the Master and slave are communicating successfully, the values in SLAVE CFG LIST will match the values in TRANSFER LIST.

Note: Each list is a hexadecimal representation of a bitmap of slave addresses on the PROFIBUS network. In the illustration above, a value of 20h in the rightmost columns of both of the first two lists means one slave at address 125 is configured and communicating with the Master. Notice that the values in the leftmost columns of the first two lists do not match. This means that the slave at address 1 is configured, but is not communicating with the Master. The slave at address 3, however, is both configured and communicating with the Master. Below is an explanation on how to read these bitmaps.

Each (XX XX) grouping represents one word containing 16 slave addresses.

In SLAVE CFG LIST in the example above

To find out which slave addresses in Word 1 are occupied by configured slaves, expand Word 1's hexadecimal numbers into a bitmap.

Note: A zero (0) in the bitmap indicates an unoccupied slave address; one (1) indicates that the slave address is occupied by a configured slave.

Here is the bitmap for Word 8:

So from the SLAVE CFG LIST, we can tell that there are configured slaves at slave addresses 1, 3 and 125.

The TRANSFER LIST indicates which configured slaves are actually communicating with the Master. Notice that Word 1 is different in the TRANSFER LIST.

Here is the bitmap for Word 1 in the TRANSFER LIST:

In conclusion, there are configured slaves at addresses 1,3 and 125, but only the slaves at addresses 3 and 125 are communicating with the Master.

Tip: This slave status data is also found in the M1 file, which is copied to the user-accessible N11 file by the sample ladder logic. You can use this data for process control. For more information, see Backplane Data Transfer (page 115).

In This Chapter

 Adding the Module to an Existing Project .............................................. 60

Ladder logic is required for the MVI46-PDPMV1 module to work. Tasks that must be handled by the ladder logic are module data transfer, special block handling, and status data receipt. Additionally, a power-up handler may be needed to handle the initialization of the module’s data and to clear any processor fault conditions.

The sample ladder logic, on the inRAx CD-ROM, is extensively commented, to provide information on the purpose and function of each rung. For most applications, the sample ladder will work without modification.

The MVI46-PDPMV1 PROFIBUS DP Master uses a process called Mailbox Messaging to exchange parameter data between the processor, Master, and slave devices. This process provides a way to encapsulate and prioritize commands and data sent between the PROFIBUS Master and slaves.

The PROFIBUS DP-V1 protocol specifies two types of data transmission messages (telegrams): Cyclic Data Telegrams and Acyclic Data Telegrams. Cyclic data communication is the exchange of normal slave input and output (I/O) data and is handled automatically by the Master in a defined, recurring, deterministic sequence based on the configuration you create in ProSoft Configuration Builder (PCB).

Acyclic communication extends data communication beyond normal I/O data to allow moving field device parameterization and calibration data over the bus during runtime and to allow for extended diagnostics and alarm messages. Acyclic data telegrams are transmitted in the gaps between cyclic data telegrams and, therefore, have a lower priority and get less bandwidth than cyclic data.

Mailbox Messaging commands are incorporated into the sample ladder logic. Mailbox messages and responses to mailbox messages are stored in mailbox data types.

The following chapter discusses these features in more detail.

Mailbox Messaging MVI46-PDPMV1 ♦ SLC Platform User Manual PROFIBUS DPV1 Master

4.1 Mailbox Message Queuing

The MVI46-PDPMV1 module operates asynchronously on the Mailbox Messages and as such provides for the queuing of the messages as they are received. The following queue sizes are used in the module.

Queue Type Queue Size Max Description

Output message from processor

Input messages for processor 126 Alarm messages from slaves

for processor

126 Number of messages that the MVI46 module

500

4.1.1 Queue Timeouts

The MVI46-PDPMV1 module will only allow a message to stay in a queue for up to 10 seconds. If the PROFIBUS Master (for output messages) or the processor (for input and alarm messages) has not successfully received a message within 10 seconds, the module will clear the message out of the queue.

will queue by type of message. Note that status of the queues can be monitored via the Queue Message Count values.

4.2 Special Function Mailbox Messaging Commands

The MVI46-PDPMV1 module supports some extended PROFIBUS functions using a mailbox data exchange mechanism.

The MVI46-PDPMV1 module supports the following special functions through this mailbox messaging scheme:

Initiated from Processor

Message Description

Set Operation Mode Controls the operating state of the PROFIBUS Master Set Slave Mode Sends special control command to one or several slaves

(Sync/Freeze) Get Slave Diag Gets diagnostic information from a slave Get Slave Config Gets slave configuration Set Slave Address Sets node address of a slave (if supported by the slave) Get Live List Gets information from all nodes on the network MSAC1 Read DPV1 acyclic read (Class 1) MSAC1 Write DPV1 acyclic write (Class 1) Start Slave Starts slaves dynamically Stop Slave Stops slaves dynamically

DPV1 Alarm Handling: Generated by Slave Devices

Message Description

Alarm Indications Spontaneous alarm indication from DPV1 slave. Structure of

data is slave-dependent Alarm Confirmation This message is sent by the MVI46 module automatically as a

confirmation to the alarm indications.

The provided simplified ladder logic is required to implement these messaging mailbox exchanges.

Sending a mailbox message to the MVI46-PDPMV1 module is a relatively simple process, however, it is important to follow a certain sequence.

each of these register locations.

4.2.1 Mailbox Message: Set Slave Mode

In addition to station-related user data transfer, which is executed automatically, 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. This permits use of sync and freeze modes for event-controlled synchronization of the slaves.

The slaves begin sync mode when they receive a sync command from their assigned Master. The outputs of all addressed slaves are then frozen in their current state. During subsequent user data transmissions, the output data are stored on the slaves, but the output states remain unchanged. The stored output data are not sent to the outputs until the next sync command is received. Sync mode is concluded with the unsync command.

Similarly, a freeze control command causes the addressed slaves to assume freeze mode. In this operating mode, the states of the inputs are frozen until the Master sends the next freeze command. Freeze mode is concluded with the unfreeze command.

Page 66 of 160 ProSoft Technology, Inc. March 25, 2011

MVI46-PDPMV1 ♦ SLC Platform Mailbox Messaging PROFIBUS DPV1 Master User Manual

Note 1: It is only possible to send control commands when operating mode is either "CLEAR" or "OPERATE". Note 2: Not all slaves support this feature. Refer to the documentation for the actual slave for more information.
