Battery Life Advisory
All modules in the MVI series use a rechargeable Lithium Vanadium Pentoxide battery to backup the 512K SRAM
memory, 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 it becomes fully charged. After it is fully charged,
the battery provides backup power for the CMOS setup and configuration data, the real-time clock, and the 512K
SRAM memory for approximately 21 days.
Before you remove a module from its power source, ensure that the battery within the module is fully charged. A fully
charged battery will hold the BIOS settings (after being removed from its power source) for a limited number of days.
When the battery is fully discharged, the module will revert to the default BIOS settings.
Note: The battery is not user replaceable.

Uploading and Downloading the Configuration File...............................34
2.1 Configuration File
The MVI69-DNP module stores its configuration in a text file called DNP.CFG,
located in the module's flash memory. When the module starts up, it reads the
configuration file and uses the information to control how the DNP 3.0
Master/Slave protocol interacts with the module's application port(s).
The configuration file is arranged in Sections, with a heading in [ ] characters at
the beginning of each section. Each Section contains a list of Parameters and
Values, followed by an optional Comment that explains the parameter.
The following illustration shows an example of a Section, a Parameter, a Value,
and a Comment.
The Parameter must be followed by a [:] (colon) character. The text following the
[:] is a Value.
The module ignores "comment" text following the [#] character. Use comments to
document your configuration settings.
You can get a sample configuration file for the module in the following places:

Adding the Module to an Existing CompactLogix Project......................47
Adding the Module to an Existing MicroLogix Project............................50
Ladder logic is required for application of the MVI69-DNP module. 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 ProSoft Solutions 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.
3.1 Module Data Objects
All data related to the MVI69-DNP is stored in two user defined data types. One
contains the status data and the other contains the DNP and IED datasets. Two
structures were used for ease of use. Any time an array's size is altered in the
RSLogix 5000 software, all the data in the object is set to zero. Because the
array sizes may need to be adjusted for the data types in an application, this data
is placed in a separate object.
An instance of each data type is required before the module can be used. This is
accomplished by declaring variables of the data types in the Controller Tags Edit
Tags dialog box. Each object is discussed in the following topics:
3.1.1 DNPModuleDef Object
The DNPModuleDef object contains all the MVI69-DNP module status data. The
structure of the object is displayed in the following example:
Tag Name Data Type Description
GenStat DNPSlvStat General status information
ErrList INT[60] List of last 60 slave errors
BP DNPBackplane Data to handle backplane logic
CmdLstErr DNPCmdLstErr

4 Diagnostics and Troubleshooting
In This Chapter
Reading Status Data from the Module ..................................................53
LED Status Indicators............................................................................66
The module provides information on diagnostics and troubleshooting in the
following forms:
Status data values are transferred from the module to the processor.
Data contained in the module can be viewed through the
Configuration/Debug port attached to a terminal emulator.
LED status indicators on the front of the module provide information on the
module's status.
4.1 Reading Status Data from the Module
The MVI69-DNP module returns a Status Data block that can be used to
determine the module's operating status. This data is located in the module's
database at a user set location. For a complete listing of the status data object,
refer to the Reference chapter. The Configuration/Debug port provides the
following functionality:
Full view of the module's configuration data
View of the module's status data
Complete display of the module's internal database (registers 0 to 3999)
Version Information
Control over the module (warm boot, cold boot, transfer configuration)
Facility to upload and download the module's configuration file
4.1.1 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 the terminal application (for
example, HyperTerminal). 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 your terminal application.

Navigation
All of the sub-menus for this module contain commands to redisplay the menu or
return to the previous menu. You can always return from a sub-menu to the next
higher menu by pressing [M] on your keyboard.
The organization of the menu structure is represented in simplified form in the
following illustration:
The remainder of this section shows you the menus available for this module,
and briefly discusses the commands available to you.
Keystrokes
The keyboard commands on these menus are almost always non-case sensitive.
You can enter most commands in lower case or capital 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],
[Ctrl] or [Alt] keys to enter them correctly. For example, on US English
keyboards, enter the [?] command as [Shift][/].
Also, take care to distinguish capital letter [I] from lower case letter [l] (L) and
number [1]; likewise for capital letter [O] and number [0]. Although these
characters look nearly the same on the screen, they perform different actions on
the module.
4.1.2 Required Hardware
You can connect directly from your computer's serial port to the serial port on the
module to view configuration information, perform maintenance, and send
(upload) or receive (download) configuration files.
ProSoft Technology recommends the following minimum hardware to connect
your computer to the module:
80486 based processor (Pentium preferred)
1 megabyte of memory
At least one UART hardware-based serial communications port available.
USB-based virtual UART systems (USB to serial port adapters) often do not
function reliably, especially during binary file transfers, such as when
uploading/downloading configuration files or module firmware upgrades.
A null modem serial cable.

Diagnostics and Troubleshooting MVI69-DNP ♦ CompactLogix or MicroLogix Platform
DNP 3.0 Master/Slave Communication Module
4.1.3 Required Software
In order to send and receive data over the serial port (COM port) on your
computer to the module, you must use a communication program (terminal
emulator).
A simple communication program called HyperTerminal is pre-installed with
recent versions of Microsoft Windows operating systems. If you are connecting
from a machine running DOS, you must obtain and install a compatible
communication program. The following table lists communication programs that
have been tested by ProSoft Technology.
DOS ProComm, as well as several other terminal emulation programs
Windows 3.1 Terminal
Windows 95/98 HyperTerminal
Windows NT/2000/XP HyperTerminal
The module uses the Ymodem file transfer protocol to send (upload) and receive
(download) configuration files from your module. If you use a communication
program that is not on the list above, please be sure that it supports Ymodem file
transfers.
4.1.4 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:
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 90).
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.

Data is being transferred between the module and a remote
terminal using the Configuration/Debug port.
The MVI69-DNP module program has recognized a
communication error on one of its DNP ports.
The LED is on when the module is performing a write
operation on the backplane.
The LED is off when the module is performing a read
operation on the backplane. Under normal operation, the LED
should blink rapidly on and off.
The card is not receiving any power and is not securely
plugged into the rack.
The program has detected an error or is being configured. If
the LED remains red for over 10 seconds, the program has
probably halted. Remove the card from the rack and re-insert
the card to restart the module's program.
The battery voltage is low or battery is not present. Allow
battery to charge by keeping module plugged into rack for 24
hours. If BAT LED still does not go off, contact ProSoft
Technology, as this is not a user serviceable item.
If a configuration error is found for the client, the client configuration error word
will have a value other than zero. The configuration error word bits have the
following definitions:

Correct any invalid data in the configuration for proper module operation. When
the configuration contains a valid parameter set, all the bits in the configuration
word will be clear. This does not indicate that the configuration is valid for the
user application. Make sure each parameter is set correctly for the specific
application.
If the APP, BP ACT and OK LEDs blink at a rate of every one-second, this
indicates a serious problem with the module. Call ProSoft Technology support to
arrange for repairs.
4.2.1 Clearing a Fault Condition
Typically, if the OK LED on the front of the module turns red for more than ten
seconds, a hardware problem has been detected in the module, or the program
has exited.
To clear the condition, follow these steps:
1 Turn off power to the rack
2 Remove the card from the rack
3 Verify that all jumpers are set correctly
4 If the module requires a Compact Flash card, verify that the card is installed
correctly
5 Re-insert the card in the rack and turn the power back on
6 Verify the configuration data being transferred to the module from the
CompactLogix or MicroLogix processor.
If the module's OK LED does not turn green, verify that the module is inserted
completely into the rack. If this does not cure the problem, contact ProSoft
Technology Support.

MVI69-DNP ♦ CompactLogix or MicroLogix Platform Reference
DNP 3.0 Master/Slave Communication Module
5.2 Functional Overview
This section provides an overview of how the MVI69-DNP module transfers data
using the DNP protocol. You should understand the important concepts in this
chapter before you begin installing and configuring the module.
5.2.1 General Concepts
The following discussion explains several concepts that are important for
understanding the operation of the MVI69-DNP module.
Module Power Up
On power up the module begins performing the following logical functions:
1 Initialize hardware components.
o Initialize CompactLogix or MicroLogix backplane driver.
o Test and Clear all RAM.
o Initialize the serial communication ports.
o Initialize the TCP/IP stack and Ethernet interface.
2 Read module configuration from DNP.CFG file on Compact Flash disk or
Flash RAM (depending on hardware configuration).
3 Initialize the Module Register Space.
4 Enable Client and/or Server driver on selected ports, as configured.
When this initialization procedure is complete, the module will begin
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 following functions:

Reference MVI69-DNP ♦ CompactLogix or MicroLogix Platform DNP 3.0 Master/Slave Communication Module
Backplane Data Transfer
The MVI69-DNP module communicates directly over the CompactLogix or
MicroLogix backplane. Data is paged between the module and the CompactLogix
processor across the backplane using the module's input and output images. The
update frequency of the images is determined by the scheduled scan rate
defined by the user for the module and the communication load on the module.
Typical updates are in the range of 2 to 10 milliseconds.
The data is paged between the processor and the module using input and output
image blocks.
This bi-directional transference of data is accomplished by the module filling in
data in the module's input image to send to the processor. Data in the input
image is placed in the Controller Tags in the processor by the ladder logic. The
input image for the module may be set to 62 words.
The processor inserts data to the module's output image to transfer to the
module. The module's program extracts the data and places it in the module's
internal database. The output image for the module may be set to 61 words.
The following illustration shows the data transfer method used to move data
between the CompactLogix processor, the MVI69-DNP module and the DNP
network.
All data transferred between the module and the processor over the backplane is
through the input and output images. Ladder logic must be written in the
CompactLogix processor to interface the block data with user data files. All data
used by the module is stored in its internal database. The following illustration
shows the layout of the database:

9971 Set module's time using PLC time
9998 Warm Boot Request from PLC (Block contains no data)
9999 Cold Boot Request from PLC (Block contains no data)
Blocks 0 to 54 transfer data. Block 112 transfers error/status data. Blocks 9901
to 9999 are used for command control of the module. Each block group is
described in the following topics.
Note: Block identification codes -1 and -2 are dummy blocks. The PLC should ignore any blocks
with these numbers as data does not represent any valid information in the module. The DNP
application will ignore any write blocks with these numbers.
5.2.2 Normal Data Transfer
Normal data transfer includes the paging of the user data found in the module's
internal database in registers 0 to 4999 and the status data. These data are
transferred through read (input image) and write (output image) blocks. The
structure and function of each block is discussed in the following topics.
The block transfer numbers are fixed in the program for each DNP data type for
this application. Block numbers are assigned by the application based on the
number of points of each type. The application only allocates the number of
blocks required to hold the data point count specified. For example, if 200 digital
input points are required for the application, only block 0 is allocated and if 150
counter points are required, blocks 16 to 20 are defined. These are separate data
areas for the DNP data used by the PLC and the data used by attached IED units
that are not part of the DNP database in the module. Each block transfers 60
word-size registers.

DNP 3.0 Master/Slave Communication Module
DATA TYPE START BLOCK # MAX BLOCK # MAX # OF POINTS
These blocks are mapped into a pre-defined memory area in the module.
Pointers into the memory area are computed by the application for each data
type. The application will only copy the portion of the block that contains valid
data.
Read Block
These blocks of data transfer information from the module to the CompactLogix
processor. The structure of the input image used to transfer this data is shown
below:
Offset Description
0 Read Block ID
1 Write Block ID
2 to 61 Read Data
The Read Block ID is an index value used to determine the location of where the
data will be placed in the CompactLogix processor controller tag array of module
read data. Each transfer can move up to 60 words (block offsets 0 to 61) of data.
The Write Block ID associated with the block requests data from the
CompactLogix processor. Under normal, program operation, the module
sequentially sends read blocks and requests write blocks. For example, if three
read and two write blocks are used with the application, the sequence will be as
follows:
R1W1
R2W2R3W1R1W2R2W1R3W2R1W1

Reference MVI69-DNP ♦ CompactLogix or MicroLogix Platform DNP 3.0 Master/Slave Communication Module
This sequence will continue until interrupted by other write block numbers sent by
the controller or by a command request from a node on the DNP network or
operator control through the module's Configuration/Debug port.
The following example shows a typical backplane communication application.
Write Block
These blocks of data transfer information from the CompactLogix or MicroLogix
processor to the module. The structure of the output image used to transfer this
data is shown below:

The Write Block ID is an index value used to determine the location in the
module's database where the data will be placed as defined in the table
presented in the previous section. Each transfer can move up to 60 words (block
offsets 1 to 60) of data.
5.2.3 Command Control Blocks
Command control blocks are special blocks used to control the module or
request special data from the module. The current version of the software
supports several command control blocks, each of which are discussed in the
following topics.
Block 9901 - Event Command
This block issues one or more command control requests to slaves attached to
the DNP master port for object 12 data. When the module receives a block 9901
identification code, it places the included commands into the command queue.

5.2.4 Data Flow between MVI69-DNP Module and CompactLogix
Processor
The following topics describe the flow of data between the two pieces of
hardware (CompactLogix processor and MVI69-DNP module) and other nodes
on the DNP network under the module's different operating modes. Each port on
the module is configured to emulate a DNP master device or a DNP slave
device. The operation of each port is dependent on this configuration.
The following topics discuss the operation of these drivers.
Slave Driver
The Slave Driver mode allows the MVI69-DNP module to respond to data read
and write commands issued by a Master on the DNP network. The following flow
chart and associated table describe the flow of data into and out of the module.
Step Description
1

5
The slave port driver receives the configuration information from the configuration file.
This information configures the serial port and define the slave node characteristics.
Additionally, the configuration information contains data that can be used to offset data in
the database to addresses requested in messages received from master units.
A host device (DNP Master Unit) issues a read or write command to the module's node
address. The port driver qualifies the message before accepting it into the module.
After the module accepts the command, the data is immediately transferred to or from
the internal database in the module. If the command is a read command, the data is read
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.
After the data processing has been completed in Step 3, the response is issued to the
originating master node.
Counters are available in the Status Block that permit the ladder logic program to
determine the level of activity of the Slave Driver.

Review the Installing and Configuring the Module section for a complete list of
parameters that must be defined for a slave port. The response messages from
the slave driver include an IIN (internal indication word) defined in the Reference
chapter - Internal Indication Word.
The slave driver supports Object 110 (octet string data). Four points are preassigned values as shown in the following table.
OCTET STRING POINT LIST

Where wwww is product code, xxxx is the revision, yyyy is the operating
system number and zzzz is the run number.
3 Manufacturer name for modul e.
Master Driver Mode
In the Master mode, the MVI69-DNP module is responsible for issuing read or
write commands to slave devices on the DNP network. These commands are
user-configured in the module via the Master Command List received from the
processor or issued directly from the processor (command control). Command
status is returned to the processor for each individual command in the command
list status block. The following flow chart and associated table describe the flow
of data into and out of the module.

The Master driver obtains configuration data from the configuration file. The configuration
data obtained includes the Master Slave and Command Lists. These values are used by
the Master driver to determine the type of commands to be issued to other nodes on the
DNP network.
After configuration, the Master 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.
Presuming successful processing by the node specified in the command, a response
message is received into the Master driver for processing.
Data received from the node on the network is passed into the module's internal
database, assuming a read command.
Status data is returned to the CompactLogix processor for each command in the Master
Command List.
Refer to the Installing and Configuring the Module section for a complete
description of the parameters required to define the virtual DNP Master port.
5.3 Cable Connections
The application ports on the MVI69-DNP module support RS-232, RS-422, and
RS-485 interfaces. Please inspect the module to ensure that the jumpers are set
correctly to correspond with the type of interface you are using.
Note: When using RS-232 with radio modem applications, some radios or modems require
hardware handshaking (control and monitoring of modem signal lines). Enable this in the
configuration of the module by setting the UseCTS parameter to 1.
5.3.1 RS-232 Configuration/Debug Port
This port is physically an RJ45 connection. An RJ45 to DB-9 adapter cable is
included with the module. This port permits a PC based terminal emulation
program to view configuration and status data in the module and to control the
module. The cable for communications on this port is shown in the following
diagram:

Disabling the RSLinx Driver for the Com Port on the PC
The communication port driver in RSLinx can occasionally prevent other
applications from using the PC's COM port. If you are not able to connect to the
module's configuration/debug port using ProSoft Configuration Builder (PCB),
HyperTerminal or another terminal emulator, follow these steps to disable the
RSLinx Driver.
1 Open RSLinx and go to Communications>RSWho
2 Make sure that you are not actively browsing using the driver that you wish to
stop. The following shows an actively browsed network:
3 Notice how the DF1 driver is opened, and the driver is looking for a processor
on node 1. If the network is being browsed, then you will not be able to stop
this driver. To stop the driver your RSWho screen should look like this:
Branches are displayed or hidden by clicking on the
or the icons.
4 When you have verified that the driver is not being browsed, go to

If you see the status as running, you will not be able to use this com port for
anything other than communication to the processor. To stop the driver press
the "Stop" on the side of the window:
5 After you have stopped the driver you will see the following:
6 Upon seeing this, you may now use that com port to connect to the debug
port of the module.
Note: You may need to shut down and restart your PC before it will allow you to stop the driver
(usually only on Windows NT machines). If you have followed all of the above steps, and it will not
stop the driver, then make sure you do not have RSLogix open. If RSLogix is not open, and you
still cannot stop the driver, then reboot your PC.
5.3.2 RS-232
When the RS-232 interface is selected, the use of hardware handshaking
(control and monitoring of modem signal lines) is user definable. If no hardware
handshaking will be used, the cable to connect to the port is as shown below:

RS-232: Modem Connection
This type of connection is required between the module and a modem or other
communication device.
The "Use CTS Line" parameter for the port configuration should be set to 'Y' for
most modem applications.
This type of connection is used when the device connected to the module
requires hardware handshaking (control and monitoring of modem signal lines).

RS-232: Null Modem Connection (No Hardware Handshaking)
This type of connection can be used to connect the module to a computer or field
device communication port.
Note: If the port is configured with the "Use CTS Line" set to 'Y', then a jumper is required between
the RTS and the CTS line on the module connection.

5.3.4 RS-485
The RS-485 interface requires a single two or three wire cable. The Common
connection is optional and dependent on the RS-485 network. The cable required
for this interface is shown below:
Note: Terminating resistors are generally not required on the RS-485 network, unless you are
experiencing communication problems that can be attributed to signal echoes or reflections. In this
case, install a 120 ohm terminating resistor on the RS-485 line.
RS-485 and RS-422 Tip
If communication in the RS-422/RS-485 mode does not work at first, despite all
attempts, try switching termination polarities. Some manufacturers interpret +/and A/B polarities differently.

identification code 100 (see section above) in at offsets 62 to 119. This data is
also available for viewing on the debug monitor port. The following tables list the
error codes generated by the program with their associated description. Use the
errors to help define where problems exist in the system.

Extra bytes are received before the start bytes (0x05 and
0x64).
Mainline Data Link Layer routine could not read data
received on DNP port before it was overwritten.
Length of message does not match length value in message.
Computed CRC value for message does not match that
received in message.
Application layer received a message fragment buffer which
is too small.
Sequence numbers of multi-frame request fragments do not
increment correctly.
Source addresses contained in multi-frame request
fragments do not match.
Function code received from DNP master is not supported
for selected object/variation.
Slave does not have the specified objects or there are no
objects assigned to the requested class.
Qualifier, range or data fields are not valid or out of range for
the selected object/variation.
Application response buffer overflow condition. The response
message from the slave is too long to transmit.
Received a multi-frame message from the DNP master. This
application does not support multi-frame messages from the
master.
