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-BDW 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.

This chapter describes how to install and configure the module to work with your
application. The configuration process consists of the following steps.

1 Use RSLogix 5 to identify the module to the processor and add the module to

a project.

Note: The RSLogix 5 software must be in "offline" mode to add the module to a project.

2 Modify the example ladder logic to meet the needs of your application, and

copy the ladder logic to the processor. Example ladder logic files are provided
on the CD-ROM.

Note: If you are installing this module in an existing application, you can copy the necessary
elements from the example ladder logic into your application.

The rest of this chapter describes these steps in more detail.
The next step in installing and configuring the module is to define whether the

block transfer or side-connect interface will be utilized.

ProSoft Technology, Inc. Page 19 of 98
October 12, 2010

Installing and Configuring the Module MVI71-BDW ♦ PLC Platform
User Manual BARDAC Communication Module

If the side-connect interface is utilized (requires user-supplied side-connect
adapter), make sure the file SC_DATA.TXT on the Compact Flash Disk contains
the correct first file number. You can run the setdnpsc.exe program to set the file
number for your application. Install the module in the rack and turn on the power.
Connect the serial cable to the module’s debug/configuration port and exit the
program by pressing [ESC][X]. This will cause the program to exit and remain at
the operating system prompt. Run the setdnpsc.exe program with a command
line argument of the file number to use for the first file. For example, to select
N10: as the first file, enter the following:

SETDNPSC 10

The program will build the SC_DATA.TXT on the Compact Flash Disk (C: drive in
the root directory).

Next, define the data files for the application. If the block transfer interface is
used, define the data files to hold the user data (read and write data). 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.

If the side-connect interface is used, no ladder logic is required for data transfer.
The user data files to interface with the module must reside in contiguous order
in the processor. The first file to be used by the interface is the status/control file.
This is file number set in the SC_DATA.TXT file using the SETDNPSC.EXE
program. The following table lists the files used by the side-connect interface:

File Number Example Size Description

Cfg File N10 200 Control/Status File
Cfg File+1 N11 to 1000 Data transferred from the module to the processor
Other files for read data
Cfg File+1+n N12 to 1000 Data transferred from the processor to the module
Cfg File+1+n+m Other files for write data

n is the number of read data files minus one. Each file contains up to 1000
words.

m is the number of write data files minus one. Each file contains up to 1000
words.

More than one read and/or write file may exist in an application. This is required
when more than 1000 words of data are required. Two examples are given below
for the files used with different data set sizes:

2.2 Configuration File

In order for the module to operate, a configuration file (BARDACDW.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. 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.
[BARDAC DW Client 0] Configuration data for BARDAC DW Client 0
[BARDAC DW Client 0 Commands] Command list for BARDAC DW Client 0
[BARDAC DW Client 1] Configuration data for BARDAC DW Client 1
[BARDAC DW Client 1 Commands] Command list for BARDAC DW Client 1
[BARDAC DW Client 2] Configuration data for BARDAC DW Client 2
[BARDAC DW Client 2 Commands] Command list for BARDAC DW Client 2
[BARDAC DW Client 3] Configuration data for BARDAC DW Client 3
[BARDAC DW Client 3 Commands] Command list for BARDAC DW Client 3

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. An example of a parameter
entry is given below:

Error/Status Pointer: 3000 #Database location for Error/Status Data

The parameter label is "Error/Status Pointer" and the parameter value is 3000.
The characters after the parameter value are ignored and are used for internal
documentation of the configuration file.

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.
This section contains 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.

MVI71-BDW ♦ PLC Platform Installing and Configuring the Module
BARDAC Communication Module User Manual

The [BARDAC DW CLIENT 0 COMMANDS] section defines the BARDAC DW
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 UDP/IP network.

2.2.1 [Module]

This section of the file describes the database setup and module level
parameters.

Module Name

0 to 80 characters
This parameter assigns a name to the module that can be viewed using the

configuration/debug port. Use this parameter to identify the module and the
configuration file.

Password

Up to 20 chars
This parameter sets the password for the module. If the parameter is not set, the

module will not be password protected. The module interprets the password as a
case-sensitive string. Do not include spaces or special characters in the
password. Only alpha and numeric characters should be used.

Error/Status Pointer

-1 to 4955
Starting register location in virtual database for the error/status table. If a value of

-1 is entered, the error/status data will not be placed in the database. All other
valid values determine the starting location of the data. This data area includes
the module version information and all server error/status data.

Read Register Start

0 to 4999
The Read Register Start parameter specifies the start of the Read Data area in

module memory. Data in this area will be transferred from the module to the
processor.

Note: Total user database memory space is limited to the first 5000 registers of module memory,
addresses 0 through 4999. Therefore, the practical limit for this parameter is 4999 minus the value
entered for Read Register Count, so that the Read Data Area does not try to extend above address

4999. Read Data and Write Data Areas must be configured to occupy separate address ranges in
module memory and should not be allowed to overlap.

User Manual BARDAC Communication Module

Read Register Count

0 to 5000
The Read Register Count parameter specifies the size of the Read Data area of

module memory and the number of registers to transfer from this area to the
processor, up to a maximum of 5000 words.

Note: Total Read Register Count and Write Register Count cannot exceed 5000 total registers.
Read Data and Write Data Areas must be configured to occupy separate address ranges in
module memory and should not be allowed to overlap.

Write Register Start

0 to 4999
The Write Register Start parameter specifies the start of the Write Data area in

module memory. Data in this area will be transferred in from the processor.

Note: Total user database memory space is limited to the first 5000 registers of module memory,
addresses 0 through 4999. Therefore, the practical limit for this parameter is 4999 minus the value
entered for Write Register Count, so that the Write Data Area does not try to extend above address

4999. Read Data and Write Data Areas must be configured to occupy separate address ranges in
module memory and should not be allowed to overlap.

Read Register Count

0 to 5000
The Read Register Count parameter specifies the size of the Read Data area of

module memory and the number of registers to transfer from this area to the
processor, up to a maximum of 5000 words.

Note: Total Read Register Count and Write Register Count cannot exceed 5000 total registers.
Read Data and Write Data Areas must be configured to occupy separate address ranges in
module memory and should not be allowed to overlap.

Failure Flag Count

0 through 65535
This parameter specifies the number of successive transfer errors that must

occur before halting communication on the application port(s). If the parameter is
set to 0, the application port(s) will continue to operate under all conditions. If the
value is set larger than 0 (1 to 65535), communications will cease if the specified
number of failures occur.

Initialize Output Data

0 = No, 1 = Yes
This parameter is used to determine if the output data for the module should be

initialized with values from the processor. If the value is set to 0, the output data
will be initialized to 0. If the value is set to 1, the data will be initialized with data
from the processor. Use of this option requires associated ladder logic to pass
the data from the processor to the module.

2.2.2 [Bardac DW Client 0]

This section defines the configuration for the master device simulated on Bardac
DW UDP service port 48556 (0xBDAC).

Error/Status Pointer

-1 to 4990
Starting register location in virtual database for the error/status table for this

Client. If a value of -1 is entered, the error/status data will not be placed in the
database. All other valid values determine the starting location of the data.

Command Error Pointer

-1 to 4999
This parameter sets the address in the internal database where the Command

Error List data will be placed. If you want the Command Error List data to be
moved to the processor and placed into the ReadData array, the value entered
should be a module memory address in the Read Data area. Therefore, the
value entered should be a module memory address in the Read Data area. If the
value is set to -1, the Command Error List data will not be stored in the module's
internal database and will not be transferred to the processor's ReadData array.

Minimum Command Delay

0 to 65535
This parameter specifies the number of milliseconds to wait between the initial

issuance of a command. This parameter can be used to delay all commands sent
to slaves to avoid "flooding" commands on the network. This parameter does not
affect retries of a command as they will be issued when failure is recognized.

Response Timeout

0 to 65535 milliseconds
This is the time in milliseconds that a Client will wait before re-transmitting a

command if no response is received from the addressed server. The value to use
depends on the type of communication network used, and the expected
response time of the slowest device on the network.

Retry Count

0 to 10
This parameter specifies the number of times a command will be retried if it fails.

2.2.3 [Bardac DW Client 0 Commands]

This section contains examples for a Bardac DW UDP/IP client using service port
48556 (0xBDAC). Refer to the drive documentation for a full list of Parameter
IDs. This section can contain up to 100 commands.

Command List Overview

In order to interface the MVI71-BDW module with UDP/IP server devices, you
must construct a command list. The commands in the list specify the server
device to be addressed, the function to be performed (read or write), the data
area in the device to interface with, and the registers in the internal database to
be associated with the device data. The Client command list supports up to 100
commands.

The command list is processed from top (command #0) to bottom. A poll interval
parameter is associated with each command to specify a minimum delay time in
tenths of a second 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 1 second.

Write commands have a special feature, as they can be set to execute only if the
data in the write command changes. If the register data values in the command
have 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
network. In order to implement this feature; set the enable code for the command
to a value of 2.

Commands Supported by the Module

The format of each command in the list depends on the BARDAC DW Function
Code being executed. The tables below list the functions supported by the
module:

Function Code Definition Supported in Client

0 Get (read data) X
1 Set (write data) X

Each command list record has the same general format. The first part of the
record contains the information relating to the communication module and the
second part contains information required to interface to the BARDAC DW
UDP/IP server device.

1 112 0 0 192.168.0.67 0 180
END

Parameter Range Description

Enable 0, 1, 2 This field defines whether the command is to be executed and

under what 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 will be
executed, when the interval timer expires.

2 The command will execute only if the internal data

associated with the command changes. This value
is valid only for write commands.

Because the BARDAC devices use the UDP protocol, the
communication between the module and the device is not as
reliable as with the TCP/IP protocol. For this reason, ProSoft
suggests that the Enable Code of 2 not be used because a specific
command may not be transferred. Therefore, it is strongly
suggested to use the Enable Code of 1 to send SET commands.

User Manual BARDAC Communication Module

Parameter Range Description

DB Address 0 to 4999 This field specifies the internal database register to be associated

with the command.

- If the command is a read function, the data read from the Server
device will be placed starting at the register value entered in this
field.

If the command is a write function, the data written to the Server
device will be sourced from the address specified.

The correct format depends on the parameter type. The following
provides examples of the most common types:

Time Secs (XX.X)
PLC = 1 <=> BARDAC DRIVE = 0.1 sec
PLC = 100 <=> BARDAC DRIVE = 10.0 sec
PLC = 1019 <=> BARDAC DRIVE = 101.9 sec
Percentage (X.XX)
PLC = 1 <=> BARDAC DRIVE = 0.01%
PLC = 10 <=> BARDAC DRIVE = 0.10%
PLC = 10000 <=> BARDAC DRIVE = 100.00%
ENABLED/DISABLED
PLC = 0 <=> BARDAC = DISABLED
PLC = 1 <=> BARDAC = ENABLED

Poll Delay 0 to 65535

This parameter specifies the minimum interval to
execute continuous commands (Enable code of 1).
The parameter is entered in units of 1/10th seconds.
Therefore, if a value of 10 is entered for a command,
the command will execute no more frequently than
every 1 second.

Swap Code 0, 1, 2, 3 This parameter is used only for functions 3, 4, 6, and 16 to define if

the data received (or sent) from the module is to be ordered
differently than data received from the server device. This
parameter is helpful when dealing with floating-point or other multi­register 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:

Code Description

0 None – No Change is made in the byte

ordering
1 Words – The words are swapped
2 Words & Bytes – The words are swapped

then the bytes in each word are swapped
3 Bytes – The bytes in each word are

swapped

When swapping words, make sure you are using an even value in
the Count Field. Odd values may generate unexpected results.

Node IP
Address

xxx.xxx.xxx.xxx The IP address of the device being addressed by the command.
