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.

1.3 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 MVI71-DFNT 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.

Installing and Configuring the Module MVI71-DFNT ♦ PLC 5 User Manual EtherNet/IP Client/Server Communication Module

The rest of this chapter describes these steps in more detail. Set up of the MVI71-DFNT module requires software configuration using the

RSLogix 5 program and the DFNT.CFG file on the Compact Flash Disk in the module. The easiest method to implement the module is to start with the appropriate example provided with the module MVI71DFNT_BT.RSP for the block transfer interface and the default configuration file. If you are installing this module in an existing application, you can copy the elements required from the example ladder logic to your application.

It is now time to edit the DFNT.CFG file to set up the module for the specific application. Refer to the Configuration File section of this document. Download this configuration to the module along with the associated ladder logic.

Enter the ladder logic to handle the blocks transferred between the module and the PLC. Download the program to the PLC and test the program with the module.

The module is now set up and ready for your application. Insert the module in the rack (with the power turned off) and attach the serial communication cables. Download the new application to the controller and place the processor in run mode. Download the new DFNT.CFG file to the module using a terminal emulation program. If all the configuration parameters are set correctly and the module is attached to a network, the module’s Application LED (APP LED) should remain off and the backplane activity LED (BP ACT) should blink very rapidly. Refer to Diagnostics and Troubleshooting if you encounter errors. Attach a computer or terminal to Port 0 on the module and look at the status of the module using the Configuration/Debug Menu in the module.

2.2 Configuration File

In order for the module to operate, a configuration file (DFNT.CFG) is required. This configuration file contains information to set the data transfer characteristics between the module and the processor, to configure the module's client and command list, and to configure the pass-through features. Each parameter in the file must be set carefully in order for the application to be implemented successfully.

The configuration file is separated into sections with topic header names enclosed in the [ ] characters. The configuration file consists of the following sections:

[Section] Description

[Module] General module configuration information [DFNT Client 0] Configuration for the DFNT client [DFNT Client 0 Commands] Command list for the DFNT client [DF1 Pass-Through Server Port 1] Parameters for the pass-through port of the second port

[DF1 Pass-Through Port] Parameters for the DF1 port emulated on the third port of

After each section header, the file contains a set of parameters. Unique labels are used under each section to specify a parameter. Each label in the file must be entered exactly as shown in the file for the parameter to be identified by the program. If the module is not considering a parameter, look at the label for the data item. Each parameter's value is separated from the label with the ":" character. This character is used by the program to delimit the position in the data record where to start reading data. All data for a parameter must be placed after the ":" character. For numeric parameter values any text located after the value will not be used. There must be at least one space character between the end of the parameter value and the following text.

Any record that begins with the "#" character is considered to be a comment record. These records can be placed anywhere in the file as long as the "#" character is found in the first column of the line. These lines are ignored in the file and can be used to provide documentation within the configuration file. Liberal use of comments within the file can ease the use and interpretation of the data in the file.

The client command list section is formatted differently than the other sections. These sections contain lists of parameters to be used. Each list begins with the label START and when the END label is reached. When entering the records into the list, make certain that the first character in each line is left blank.

The [DFNT CLIENT 0 COMMANDS] section defines the Ethernet/IP commands to be issued from the module to server devices on the network. These commands can be used for data collection and/or control of devices on the TCP/IP network.

Installing and Configuring the Module MVI71-DFNT ♦ PLC 5 User Manual EtherNet/IP Client/Server Communication Module

Command List

In order to interface the virtual database with DF1 slave devices, you must construct a command list. The commands in the list specify the DF1 slave device to be utilized, the function to be performed (read or write), the data area in the device to interface with and the position in the virtual database to be associated with the device data. There is a separate command list for each DF1 master device emulated. The list is processed from top (command #0) to bottom. A poll interval parameter is associated with each command to specify a minimum delay time between the issuance of a command. If the user specifies a value of 10 for the parameter, the command will be executed no more frequently than every 10 seconds for the serial implementation and 1 second for the network implementation.

Write commands have a special feature, as they can be set to execute only if the data in the write command changes. If the data in the command has not changed since the command was last issued, the command will not be executed. If the data in the command has changed since the command was last issued, the command will be executed. Use of this feature can lighten the load on the DF1 network. In order to implement this feature; set the enable code for the command to a value of 2.

If the module is configured for the serial DF1 half-duplex protocol, the module can act as a master device routing messages between attached slave devices. This peer-to-peer communication is defined in the DF1 protocol specification. The master polls each DF1 slave device until no more data is available from the device. Response messages from the slaves that have a destination address that do not match the module are routed with a request message header back out onto the network. This facility offers communication between the slave devices for control and data monitoring. This feature is not available if the module is configured for DF1 full-duplex mode (point-to-point).

The module supports numerous commands. This permits the module to interface with a wide variety of DF1 protocol devices. This includes PLC2, PLC5, SLC-500 series, MicroLogix and ControlLogix processors. Additionally, other devices supplied by Rockwell Automation that use the DF1 protocol are supported.

The format of each command in the list depends on the function being executed. To simplify command construction, the module uses its own set of function codes to associate a command with a DF1 command/function type. The tables below list the functions supported by the module:

conditions.

Value Description

0 The command is disabled and will not be executed in the normal

polling sequence.

1 The command is executed each scan of the command list if the

Poll Interval Time is set to zero. If the Poll Interval time is set, the command is executed when the interval timer expires.

2 The command executes only if the internal data associated with

the command changes. This value is valid for write commands

Internal Address

0 to 3999 This field specifies the database address in the module's internal database to

be associated with the command. If the command is a read function, the data received in the response message is placed at the specified location. If the command is write function, data used in the command is sourced from the specified data area.

Poll Delay 0 to 1000 This parameter specifies the minimum interval to execute continuous

commands (Enable code of 1). The parameter is entered in 1/10th of a second. Therefore, if a value of 100 is entered for a command, the command executes no more frequently than every 10 seconds.

Count Command dependent. This parameter specifies the number of registers or digital points to be

associated with the command. See Command Function Codes (page 34) for information

Swap Code 0, 1, 2, 3 This parameter defines if the data received from the Server is to be ordered

differently than that received from the Server device. This parameter is helpful when dealing with floating-point or other multi-register values, as there is no standard method of storage of these data types in Server devices. This parameter can be set to order the register data received in an order useful by other applications. The following table defines the values and their associated operations:

2.3 IP Address

In addition to the DFNT.CFG, the MVI71-DFNT module requires a second configuration file that identifies its Ethernet configuration. Without this configuration file, the module will not communicate properly on the network.

This file contains the Ethernet address information to be used by the module and may be transferred to and from the module from the Network command available on the debug port of the module. Please consult your network administrator for the correct settings for your network before placing this or any other Ethernet TCP/IP device upon your network.

Important: If the field "my_ip" does not exist, or if the wattcp.cfg file is corrupted or does not exist, the module will not function.

To set the Module’s IP Address

1 Locate the sample configuration files for your module on the ProSoft

Solutions CD.

2 Copy the configuration files and ladder to a location on your PC’s hard drive.

We recommend C:\temp.

3 After you move the files, right-click on each of the files, choose Properties,

and clear the READ ONLY check box.

4 Start Notepad.exe, or any other editor that can save plain text files. 5 Open the file WATTCP.CFG. The following example shows the contents of a

typical WATTCP.CFG file.

# ProSoft Technology # Default private class 3 address my_ip=192.168.0.100

# Default class 3 network mask netmask=255.255.255.0

# The gateway I wish to use gateway=192.168.0.1,192.168.0.0,255.255.255.0

6 Edit the file, using the IP addresses supplied by your network administrator.

Important: The module does not support DHCP (Dynamic Host Configuration Protocol) for obtaining an IP address from a server. This module must have its own static IP address that does not duplicate the IP address of any other device on the Ethernet network.

4.2 The Configuration/Debug Menu

The Configuration and Debug menu for this module is arranged as a tree structure, with the Main Menu at the top of the tree, and one or more sub-menus for each menu command. The first menu you see when you connect to the module is the Main menu.

Because this is a text-based menu system, you enter commands by typing the command letter from your computer keyboard in Prosoft Configuration Builder (PCB). The module does not respond to mouse movements or clicks. The command executes as soon as you press the command letter — you do not need to press [Enter]. When you type a command letter, a new screen will be displayed in the Prosoft Configuration Builder (PCB) application.

4.2.1 Navigation

All of the submenus for this module contain commands to redisplay the menu or return to the previous menu. You can always return from a submenu to the next higher menu by pressing [M]

The organization of the menu structure is represented in simplified form in the following illustration:

on your keyboard.

The remainder of this section shows the menus available for this module, and briefly discusses the commands available to you.

Keystrokes

The keyboard commands on these menus are usually not case sensitive. You can enter most commands in lowercase or uppercase letters.

The menus use a few special characters (?, -, +, @) that must be entered exactly as shown. Some of these characters will require you to use the SHIFT,

ALT

keys to enter them correctly. For example, on US English keyboards, enter

the ?

command as SHIFT and /.

Also, take care to distinguish the different uses for uppercase letter "eye" (I),

CTRL, or

lowercase letter "el" (L), and the number one (1). Likewise, uppercase letter "oh" (O)

and the number zero (0) are not interchangeable. Although these characters

look alike on the screen, they perform different actions on the module and may not be used interchangeably.

4.2.2 Using the Configuration/Debug Port

To connect to the module’s Configuration/Debug port:

1 Connect your computer to the module’s port using a null modem cable. 2 Start the communication program on your computer and configure the

communication parameters with the following settings:

Baud Rate 57,600 Parity None Data Bits 8 Stop Bits 1 Software Handshaking None

3 Open the connection. When you are connected, press the [?] key on your

keyboard. If the system is set up properly, you will see a menu with the module name followed by a list of letters and the commands associated with

them. If there is no response from the module, follow these steps: 1 Verify that the null modem cable is connected properly between your

computer’s serial port and the module. A regular serial cable will not work. 2 Verify that RSLinx is not controlling the COM port. Refer to Disabling the

RSLinx Driver for the Com Port on the PC (page 84). 3 Verify that your communication software is using the correct settings for baud

rate, parity and handshaking. 4 On computers with more than one serial port, verify that your communication

program is connected to the same port that is connected to the module. If you are still not able to establish a connection, you can contact ProSoft

Technology Technical Support for further assistance.

5.2 Functional Overview

5.2.1 General Concepts

The following discussion explains several concepts that are important for understanding module operation.

Module Power Up

On power up the module begins performing the following logical functions:

1 Initialize hardware components 2 Initialize PLC backplane driver

o Test and clear all RAM o Initialize the serial communication ports o Read configuration for module from DFNT.CFG file on Compact Flash

Disk

3 Initialize Module Register space 4 Enable Server Drivers 5 Enable Client Driver 6 Initialize all serial communication ports

After the module receives the configuration, the module begins communicating with other nodes on the network, depending on the configuration.

Main Logic Loop

Upon completing the power-up configuration process, the module enters an infinite loop that performs the functions shown in the following diagram.

ProSoft Technology, Inc. Page 69 of 175 February 3, 2011

Reference MVI71-DFNT ♦ PLC 5 User Manual EtherNet/IP Client/Server Communication Module

Block Transfer Backplane Data Transfer

The MVI71-DFNT module communicates directly over the PLC backplane. Data is paged between the module and the PLC processor across the backplane using BTR and BTW operations. Data is transferred from the module to the processor using the BTR blocks, and data is transferred from the processor to the module using BTW blocks.

The following illustration shows the data transfer method used to move data between the PLC processor, the MVI71-DFNT module, and the Ethernet Network.

As shown in the diagram, all data transferred between the module and the processor over the backplane is through the BTR and BTW blocks. Ladder logic must be written in the PLC processor to interface the block data with the module's internal database. All data used by the module is stored in its internal database. The following illustration shows the layout of the database:

5.2.2 Normal Data Transfer

Normal data transfer includes the transferring of data between the MVI71-DFNT database and the PLC data files. These data are transferred through read (BTR) and write (BTW) blocks. Refer to the Module Configuration section for a description of the ladder logic required to perform the data movement within the PLC processor. The structure and function of each block is discussed in the following topics.

Read Block

These blocks of data transfer information from the module to the PLC processor. When data is received on one of the servers, a data block is built. The structure of this block type is shown in the following table.

Word Offset Description

0 Read Block ID 1 Next Write Block ID 2 to 63 Read Data

Write Block

These blocks of data transfer information from the PLC processor to the module. The structure of the BTW block is shown in the following table.

Word Offset Description

0 Write Block ID (copied from the previous Read block) 1 to 63 Write Data

The following shows the valid block IDs for normal transfer:

Block ID Definition

-1 and 0 Null blocks that do not contain any data. 1 to 67 Data read and write blocks to transfer data for the module’s database

between the processor and the module.

How Data is Transferred

In order to understand how the data is transferred between the processor and the module, you must understand the Read Data and Write Data area concept in the module’s database. The module’s database can be partially, or totally divided into Read Data Areas and Write Data Areas.

These areas are defined by the user when the configuration file is being edited. The following parameters define the Read and Write data areas:

Read Register Start = 0 Read Register Count = 120 Write Register Start = 200 Write Register Count = 120

Each area is broken down into blocks of 60 words. Therefore, the Read Register Count and Write Register Count parameters should be multiples of 60.

ProSoft Technology, Inc. Page 71 of 175 February 3, 2011

Reference MVI71-DFNT ♦ PLC 5 User Manual EtherNet/IP Client/Server Communication Module

The Read Data Area will be transferred from the module to the PLC processor. The Write Data Area will be transferred from the PLC processor to the module.

The following example shows the resulting data flow:

5.2.3 Module Control Blocks

Specific write block IDs are reserved for module control operations. These blocks request that the module perform specific tasks. The following write blocks are valid for module control.

MVI71-DFNT ♦ PLC 5 Reference EtherNet/IP Client/Server Communication Module User Manual

Status Data Request Block (250 to 254)

In order to read the module’s general error and status data to the PLC, it must make a special request using the status data request block. The following tables lists the values recognized by the module:

Offset Description

250 Module and pass-through port end server status 251 Status for servers 0 to 4 252 Status for servers 5 to 9 253 Status for servers 10 to 14 254 Status for servers 15 to 19

MVI71-DFNT Status Data Definition contains a complete listing of the data returned for the status blocks.

Initialize Output Data Blocks (1000 to 1066)

When the module performs a restart operation, it requests output data from the processor to initialize the module’s read data area. Use the Initialize Output Data parameter in the configuration file to bring the module to a known state after a restart operation. The structure of the block used to request the data is shown in the following table.

Block Request

Offset Description Length

0 1000 to 1066 1 1 1000 to 1066 1 2 to 63 Not used 62

The command control value of 1000 is moved as the Block Transfer Write ID to indicate that the module is requesting initialization of the Read Data area. Ladder logic in the processor must recognize this command and place the correct information in the database. The format of the returned write block is shown in the following table.

Block Response

5.2.4 Data Flow between MVI71-DFNT Module and PLC Processor

The following discussion outlines the flow of data between the two pieces of hardware (PLC processor and MVI71-DFNT module) and other nodes on the TCP/IP network under the module’s different operating modes. The module contains both servers and a Client.

The following topics discuss the operation of the server and Client drivers.

Server Driver

The Server Driver allows the MVI71-DFNT module to respond to data read and write commands issued by clients on the Ethernet/IP network using explicit messaging. The following flow chart and associated table describe the flow of data into and out of the module.

Step Description

1 The server driver receives the configuration information from the configuration file on the

Compact Flash Disk, and the module initializes the servers.

2 A Host device, such as a ControlLogix processor, RSLinx or an HMI application issues a

read or write command to the module. The server driver qualifies the message before accepting it into the module.

3 After the module accepts the command, the data is immediately transferred to or from

out of the database and a response message is built. If the command is a write command, the data is written directly into the database and a response message is built.

4 After the data processing has been completed in Step 3, the response is issued to the

originating master node.

5 Status data for the servers is passed to the processor under ladder logic control using

the command control data area in the M1 file.

MVI71-DFNT ♦ PLC 5 Reference EtherNet/IP Client/Server Communication Module User Manual

The DFNT module supports server functionality using the reserved ControlNet service port 0xAF12. Services supported in the module permit client applications (that is, RSView, ControlLogix processors and RSLinx) to read from and write to the module’s database. This document discusses the requirements for attaching to the module using several client applications.

The following illustration shows the relationship of the DFNT module’s functionality to devices on an Ethernet network:

Server functionality places all data transfer operations outside the module. There is no configuration required in the module other than setting up the network and database parameters in the configuration file. Ladder logic in attached processors use MSG instructions to perform read and write operations on the module’s internal database.

When RSLinx links a user application to the module, the module’s server functionality must be used. RSLinx exists on an Ethernet network only as a client application. It cannot act as a server. User applications can use the DDE/OPC capabilities built into RSLinx to interface with the data in the DFNT module. RSView can link directly to the module using drivers supplied by RSLinx.

Client Driver

In the client driver, the MVI71-DFNT module is responsible for issuing read or write commands to servers on the Ethernet/IP network using explicit, connected messaging. These commands are user configured in the module via the Client Command List received from the module's configuration file (DFNT.CFG). Command status is returned to the processor for each individual command in the command list status block in the command control data area. Ladder logic is responsible for acquiring this data from the module. The following flow chart and associated table show the flow of data into and out of the module.

Page 80 of 175 ProSoft Technology, Inc. February 3, 2011

MVI71-DFNT ♦ PLC 5 Reference EtherNet/IP Client/Server Communication Module User Manual

Step Description

1 The client driver obtains configuration data from the DFNT.CFG file when the module

restarts. The configuration data obtained includes the timeout parameters and the Command List. These values are used by the driver to determine the type of commands to be issued to the other nodes on the Ethernet/IP (see Module Configuration).

2 After configuration, the client driver begins transmitting read and/or write commands to

the other nodes on the network. If writing data to another node, the data for the write command is obtained from the module's internal database to build the command.

3 Presuming successful processing by the node specified in the command, a response

message is received into the client driver for processing.

4 Data received from the node on the network is passed into the module's internal

database, assuming a read command.

5 Status data is returned to the PLC processor for the client and a Command List error

table can be established in the module's internal database. This data is requested using the command control data area and is a responsibility of the ladder logic.

The Module Setup section provides a complete description of the parameters required to define the client.

Client Command List

In order for the client to function, the module's Client Command List must be defined. This list contains up to 100 individual entries, with each entry containing the information required to construct a valid command. This includes the following:

 Command enable mode ((0) disabled, (1) continuous or (2) conditional)  IP address of the remote server  Slot number for processor when interfacing with a ControlLogix processor  Command Type - Read or Write command  Database Address - Determines where data will be placed and/or obtained  Address information to access data in remote unit  Count - Select the number of words to be transferred  Poll Delay - (1/10

seconds)
