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.

Installing and Configuring the Module MVI46-DFCM ♦ SLC Platform
DF1 Communication 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 500 to identify the module to the processor and add the module
to a project.
Note: The RSLogix 500 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 existin g 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.
First, define the module to the system. Select the I/O Configuration option from
the program screen. This will display the following dialog box:

Select the Other module from the list. This action opens the following dialog box.
Enter the module I/O card ID number as 12835, and then click OK. Double-click
the mouse on the module just added to the rack. Fill in the dialog box presented
as shown below:
Click OK to apply these settings to the module. Then, close the I/O Configuration
dialog box.
Next, define the user defined data areas to hold the configuration, port command
lists, status and read and write database areas.
At this point, take the time to fill in the configuration values in the DFCM
configuration data table. Refer to the Module Data section of this document for
information on configuring the module.
The last step in the module setup is to add the ladder logic. If the example ladder
logic is used, adjust the ladder to fit the application. When the ladder example is
not used, copy the example ladder logic to your application and alter as
necessary.
The module is now set up and ready to be used with your application. Insert the
module in the rack and attach the DF1 serial communication cables. Download
the new application to the controller and place the processor in run mode. If all
the configuration parameters are set correctly and the module is attached to a
DF1 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
& Troubleshooting (page 35) if you encounter errors. Attach a computer or
terminal to Debug/Configuration port on the module and look at the status of the
module using the Configuration/Debug Menu in the module. Refer to
Troubleshooting (page 52) for a complete discussion of the use of this feature.

Installing and Configuring the Module MVI46-DFCM ♦ SLC Platform
DF1 Communication Module
2.1 Module Configuration
In order for the MVI46-DFCM module to function, a minimum amount of
configuration data must be transferred to the module. The following table
provides an overview of the different types of configuration data that the module
will require, depending on the operating modes to be supported.
Module Register
Address
5000 to 5009 Data Transfer General Module
5010 to 5039 and
5040 to 5069
5200 to 6399 and
6400 to 7599
Refer to MVI46-DFCM Configuration Data Definition for a description of the
configuration of the module. The MVI46-DFCM module must be configured at
least once when the card is first powered, and any time thereafter when the
parameters must be changed.

Configuration
Command List
This section of the configuration data contains the module
configuration data that defines the data transfer between the
module and the SLC processor.
These sections define the characteristics of each of the DF1
serial communication ports on the module. These
parameters must be set correctly for proper module
operation.
If the module's Master Mode functionality is to be supported
on a port, the Master Command List must be set up.
2.1.1 Changing Parameters During Operation
A copy of the module's configuration data is mapped in the module's M1 file as
displayed in the table above. These values are initialized when the module first
receives its configuration from the SLC processor. Any node on the network can
change this data. A master port on the module may poll a slave for the data or a
slave port could receive the data from a remote master unit. The module will not
use this data until it is commanded. Ladder logic can be written to issue a Write
Configuration command block (9997) to the module. A remote device can set a
value of 9997 at address 7800 (N46:0) in the module to download the
configuration to the processor. Alternatively, the configuration/debug port on the
module can be used to issue the command directly to the module. All three of
these methods will force the module to download the configuration to the SLC
processor. Ladder logic must exist in the processor to accept the block sent by
the module. If everything is configured correctly, the module can receive its
configuration from a remote device.
2.2 MVI46-DFCM Configuration
This section contains a listing of the MVI46-DFCM configuration data locations in
the SLC M0 file, as well as the same data locations as emulated in the MVI46DFCM module's internal database. The module will continually request the data
from the processor until a valid configuration is received. This information is
stored in the module's M1 file and a reserved, faster RAM area in the module.
Data is constantly moved from the M1 file data areas 0 to 4999 to the fast RAM
area.

DF1 Communication Module
3 Ladder Logic
Ladder logic is required for application of the MVI46-DFCM 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.

In This Chapter
Reading Status Data from the Module ..................................................35
LED Status Indicators............................................................................ 50
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 MVI46-DFCM module contains a 33-word Status Data block that can be
used to determine the module's operating status. This data is located in the
module's database at registers 7600 (N45:0) to 7632 (N45:32) and at the location
specified in the configuration. This data can be transferred to the SLC processor
continuously with use of ladder logic. For a complete listing of the status data
object, refer to MVI46-DFCM STATUS DATA DEFINITION. Refer to Diagnostics
& Troubleshooting (page 35) for a discussion of the features available through
the use of this utility.
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.

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 serial communications port available
A null modem serial cable.
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
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:
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.

Diagnostics and Troubleshooting MVI46-DFCM ♦ SLC Platform
DF1 Communication Module
2 Verify that RSLinx is not controlling the COM port. Refer to Disabling the
RSLinx Driver for the Com Port on the PC (page 72).
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.
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.

From this menu, you can select the "Port", the "format", and the "ticks" that you
can display the data in.
For most applications, HEX is the best format to view the data, and this does
include ASCII based messages (because some characters will not display on
HyperTerminal and by capturing the data in HEX, we can figure out what the
corresponding ASCII characters are supposed to be).
The Tick value is a timing mark. The module will print a _TT for every xx
milliseconds of no data on the line. Usually 10milliseconds is the best value to
start with.
After you have selected the Port, Format, and Tick, we are now ready to start a
capture of this data. The easiest way to do so is to go up to the top of you
HyperTerminal window, and do a Transfer / Capture Text as shown below:
After selecting the above option, the following window will appear:
Next name the file, and select a directory to store the file in. In this example, we

The MVI46-DFCM module program has recognized a
communication error on one of its ports or a backplane error.
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. Turn off the power to the rack, remove the
card from the rack and visually inspect the module. Re-insert
the card and turn on the power to the rack 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.
During module configuration, the OK LED will be red and the APP and BP ACT
LEDs will be on. If the LEDs are latched in this mode for a long period of time,
look at the configuration error words in the configuration request block. The
structure of the block is as shown below:

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
words 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 SLC
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.

5.2 Functional Overview
This section provides an overview of how the MVI46-DFCM module transfers
data using the DFCM 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 MVI46-DFCM module.
Module Power Up
On power-up, the module begins performing the following logical functions:
1 Initialize hardware components
o Initialize SLC backplane driver
o Test and Clear all RAM
o Initialize the serial communication ports
2 Wait for Module Configuration from SLC processor
3 Initialize Module Register space
4 Enable Slave Driver on selected ports
5 Enable Master Driver on selected ports
After the module has received the Module Configuration Block from the
processor, the module will begin communicating with other nodes on the
network, depending on the configuration.
ProSoft Technology, Inc. Page 55 of 103
October 20, 2008
MVI46-DFCM ♦ SLC Platform Reference
DF1 Communication Module
Main Logic Loop
Upon completing the power up configuration process, the module enters an
infinite loop that performs the following functions:
SLC Processor Not in Run
Whenever the module detects that the processor has gone out of the Run mode
(that is, Fault or PGM), the DF1 ports will be shut down. When the processor is
returned to a running state, the module will resume communications on the
network. No backplane data transfers will occur when the processor is not in run
mode.
Backplane Data Transfer
The MVI46-DFCM module communicates directly over the SLC backplane. All
data for the module is contained in the module's M1 file. Data is moved between
the module and the SLC processor across the backplane using the module's Mfiles. The SLC scan rate and the communication load on the module determine
the update frequency of the M-files. The COP instruction can be used to move
data between user data files and the module's M1 file.
Page 56 of 103 ProSoft Technology, Inc.
October 20, 2008
Reference MVI46-DFCM ♦ SLC Platform DF1 Communication Module
The following illustration shows the data transfer method used to move data
between the SLC processor, the MVI46-DFCM module and the DF1 network.
All data transferred between the module and the processor over the backplane is
through the M0 and M1 files. Ladder logic must be written in the SLC processor
to interface the M-file data with data defined in the user-defined data files in the
SLC. All data used by the module is stored in its internal database. The following
illustration shows the layout of the database:
ProSoft Technology, Inc. Page 57 of 103
October 20, 2008
MVI46-DFCM ♦ SLC Platform Reference
DF1 Communication Module
User data contained in this database is continuously read from the M1 file. The
configuration data is only updated in the M1 file after each configuration request
by the module to the SLC. All data in the M1 file is available to devices on the
DF1 networks. This permits data to be transferred from these devices to the SLC
using the user data area. Additionally, remote devices can alter the module's
configuration, read the status data and issue control commands. Block
identification codes define specific functions to the module.
The block identification codes used by the module are listed below:
Block Range Descriptions
1000 Event Port 1
2000 Event Port 2
3000 to 3001 Port 1 slave polling control
3100 to 3101 Port 2 slave polling control
5000 to 5006 Port 1 command control
5100 to 5106 Port 2 command control
9000 Configuration request from module
9001 Configuration ready from controller
9997 Write configuration to controller
9998 Warm-boot control block
9999 Cold-boot control block
Each block has a defined structure depending on the data content and the
function of the data transfer as defined in the following topics.
Normal Data Transfer
This version of the module provides for direct access to the data in the module.
All data related to the module is stored in the module's M1 file. To read data from
the module, use the COP instruction to copy data from the module's M1 file to a
user data file. To write data to the module, use the COP instruction to copy data
from a user file to the module's M1 file. Registers 0 to 4999 should be used for
user data. All other registers are reserved for other module functions.
Configuration Data Transfer
When the module performs a restart operation, it will request configuration
information from the SLC processor. This data is transferred to the module in a
specially formatted write block in the M0 file. The module will poll for this
information by placing the value 9000 in word 0 of the M0 file. The ladder logic
must construct the requested block in order to configure the module. Refer to
Installing and Configuring the Module (page 19) for a description of the data
objects used with the blocks and the ladder logic required. The format of the
block for configuration is given in the following section.
Page 58 of 103 ProSoft Technology, Inc.
October 20, 2008
Reference MVI46-DFCM ♦ SLC Platform DF1 Communication Module
Module Configuration Data
This block sends configuration information from the processor to the module. The
data is transferred in a block with an identification code of 9001. The structure of
the block is displayed below:
M0 Offset Description Length
0 9001 1
1 to 6 Backplane Set Up 6
7 to 31 Port 1 Configuration 25
32 to 56 Port 2 Configuration 25

1281 to 2444 Port 2 Commands # 2 to # 98 1164
2445 to 2456 Port 2 Command # 99 Definition 12
If there are any errors in the configuration, the bit associated with the error will be
set in one of the two configuration error words. The error must be corrected
before the module starts operating.
Slave Status Data
Slave status data sends status information of each slave device on a master port.
Slaves attached to the master port can have one of the following states:
Status Description
0 The slave is inactive and not defined in the command list for the master port.
1
2
3
The slave is actively being polled or controlled by the master port and
communications is successful.
The master port has failed to communicate with the slave device. Communications
with the slave is suspended for a user defined period based on the scanning of the
command list.
Communications with the slave has been disabled by the ladder logic. No
communication will occur with the slave until this state is cleared by the ladder logic.
Slaves are defined to the system when the module initializes the master
command list. Each slave defined will be set to a state of one in this initial step. If
the master port fails to communicate with a slave device (retry count expired on a
command), the master will set the state of the slave to a value of 2 in the status
table. This suspends communication with the slave device for a user specified
scan count (Error Delay Counter value in the module configuration for each
port). Each time a command in the list is scanned that has the address of a
suspended slave, the delay counter value will be decremented. When the value
reaches zero, the slave state will be set to one. This will enable polling of the

DF1 Communication Module
In order to read the slave status table, ladder logic must be written and the slave
status data must be located in the user data area. The module will constantly
update the user defined data area with the slave data for each DF1 master port.
This data can be transferred to a user-defined file in the processor using the
COP instruction.
Ladder logic can be written to override the value in the slave status table to
disable slaves (state value of 3) by sending a special block of data from the
processor to the slave. Port 1 slaves are disabled using block 3000, and Port 2
slaves are disabled using block 3100. Each block contains the slave node
addresses to disable. The structure of the block is displayed below:
M1 Offset Description Length
7800 3000 or 3100 1
7801 Number of Slaves in Block 1
7802 to 7927 Slave indexes 126
The module will respond with a block with the same identification code received
and indicate the number of slaves acted on with the block. The format of this
response block is displayed below:
M0 Offset Description Length
0 3000 or 3100 1
1 Number of slaves processed 1
Ladder logic can be written to override the value in the slave status table to
enable the slave (state value of 1) by sending a special block. Port 1 slaves are

Command Control Block
Command control blocks place commands in the command list into the
command queue. Each port has a command queue of up to 100 commands. This
module services commands in the queue before the master command list. This
gives high priority to commands in the queue. Commands placed in the queue
through this mechanism must be defined in the master command list. Under
normal command list execution, the module will only execute commands with the
Enable parameter set to one or two. If the value is set to zero, the command is
skipped. Commands may be placed in the command list with an Enable
parameter set to zero. These commands can then be executed using the
command control blocks. One to six commands can be placed in the command
queue with a single request. The format of the block is shown in the following
table.
Event Command
Event command control blocks send DF1 commands directly from the ladder
logic to one of the master ports. The format for these blocks is displayed below:
M1 Offset Description Length
7800 1000 or 2000 1
7801 Internal DB Address 1
7802 Point Count 1
7803 Swap Code 1
7804 Node Address 1
7805 Function Code 1
7806 Parameter #1 1
7807 Parameter #2 1
7808 Parameter #3 1
7809 Parameter #4 1
The block number defines the DF1 port to be considered. Block 1000 commands
are directed to Port 1, and block 2000 commands are directed to Port 2. The
parameters passed with the block construct the command. The Internal DB Address parameter specifies the module's database location to associate with
the command. The Point Count parameter defines the number of registers for
the command. The Swap Code changes the word or byte order. The Node
Address parameter defines the device on the DF1 network to consider. The
Function Code parameter is one of those defined in the ProSoft DF1 Command
Set documentation. The parameter fields in the block should be completed as
required by the selected function code. Each command has its own set of
parameters. When the block is received, the module will process it and place the
command in the command queue. The module will respond to each event
command block with a read block with the following format:
M0 Offset Description Length
0 1000 or 2000 1
1 0=Fail, 1=Success 1

DF1 Communication Module
Word one of the block can be used by the ladder logic to determine if the
command was added to the command queue of the module. The command will
only fail if the command queue for the port is full (100 commands for each queue)
or the command requested is invalid.
Command Control
Command control blocks place commands in the command list into the
command queue. Each port has a command queue of up to 100 commands. The
module services commands in the queue before the master command list. This
gives high priority to commands in the queue. Commands placed in the queue
through this mechanism must be defined in the master command list. Under
normal command list execution, the module will only execute commands with the
Enable parameter set to one or two. If the value is set to zero, the command is
skipped. Commands may be placed in the command list with an Enable
parameter set to zero. These commands can then be executed using the
command control blocks.
One to six commands can be placed in the command queue with a single
request. The format of the block is displayed below:
M1 Offset Description
7800 5001 to 5006 or 5101 to 5106 1

7802 Command index 1
7803 Command index 1
7804 Command index 1
7805 Command index 1
7806 Command index 1
Length
Blocks in the range of 5001 to 5006 are used for Port 1, and blocks in the range
of 5101 to 5106 are used for Port 2. The last digit in the block code defines the
number of commands to process in the block. For example, a block code of 5003
contains 3 command indexes that are to be used with Port 1. The Command
index parameters in the block have a range of 0 to 99 and correspond to the
master command list entries.
The module responds to a command control block with a block containing the
number of commands added to the command queue for the port. The format of
the block is displayed below:

Write Configuration
This block is sent from the SLC processor to the module to force the module to
write its current configuration back to the processor. This function is used when
the module's configuration has been altered remotely using database write
operations. The write block contains a value of 9997 in the first word. The module
will respond with a block containing the module configuration data. Ladder logic
must handle the receipt of the block. The block transferred from the module is as
follows:

5.2.2 Data Flow between MVI46-DFCM Module and SLC Processor
The following topics describe the flow of data between the two pieces of
hardware (SLC processor and MVI46-DFCM module) and other nodes on the
DF1 network under the module's different operating modes. Each port on the
module is configured to emulate a DF1 master device or a DF1 slave device. The
operation of each port is dependent on this configuration. The sections below
discuss the operation of each mode.
Slave Driver Mode
The Slave Driver Mode allows the MVI46-DFCM module to respond to data read
and write commands issued by a master on the DF1 network. The following flow
chart and associated table describe the flow of data into and out of the module.
Step Description

5
The DF1 slave port driver receives the configuration information from the SLC processor.
This information configures the serial port and define the slave node characteristics. The
module simulates N-files to permit remote access of the database. Each file has a fixed
length of 200-word registers.
A Host device, such as the Rockwell Automation PLC or an HMI application 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 the M1 file 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.
Refer to Module Configuration (page 21) for a complete list of the parameters
that must be defined for a slave port. The slave driver supports the following DF1
command set:

200.
In order to retrieve data from the modules database register 200, the remote
master would issue a command using the address N8:0. In order to interface with
database base register 405, the remote master would use the address N9:5. The
following table outlines the complete file emulation for the module:

All the data in the module is available to a remote host. This permits the host
device to remotely configure the module and view the status data.
Master Driver Mode
In Master Mode, the MVI46-DFCM module is responsible for issuing read or write
commands to slave devices on the DF1 network. These commands are user
configured in the module via the Master Command List received from the SLC
processor or issued directly from the SLC processor (event command control).
Command status is returned to the processor for each individual command in the
command list status block. The location of this status block in the module's
internal database is user defined. The following flow chart and associated table
describe the flow of data into and out of the module.
Step Description
1
2
The Master driver obtains configuration data from the SLC processor. The configuration
data obtained includes the number of commands and the Master Command List. These
values are used by the Master driver to determine the type of commands to be issued to
the other nodes on the DF1 network (Refer to the MVI46-DFCM Module Set Up Guide).
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.

5 Status is returned to the SLC processor for each command in the Master Command List.
Data received from the node on the network is passed into the module's internal
database and the M1 file, assuming a read command.
Refer to DF1 Master Commands (page 70) for a complete description of the
parameters required to define the virtual DF1 master port. Refer to the DF1 Command Set for ProSoft Technology Communication Modules
documentation for a complete discussion of the structure and content of each
command. Care must be taken in constructing each command in the list for
predictable operation of the module. If two commands write to the same internal
database address of the module, the results will not be as desired. All commands
containing invalid data will be ignored by the module. The module does not
support the PLC-5 ASCII Address commands (150 to 152) as outlined in the DF1

Reference MVI46-DFCM ♦ SLC Platform DF1 Communication Module
If the DF1 master port is configured to support the DF1 half-duplex protocol, the
master port can be used to route messages between slaves. Peer-to-peer
communication is accomplished by the master constantly polling all the slaves on
the network and relaying the messages received. The slaves must contain ladder
logic with MSG commands to generate and accept messages. This routing can
be used in conjunction with the normal command processing discussed above. If
the slave node to be polled is not included in the command list, a special
command is required in the command list. Enter a 999 in the Enable Code and
the slave's node address in the Node Address fields of the command. No other
parameters are required for a device poll message. This command will force the
master port to issue an enquiry request to the slave device without first issuing a
command. Any messages held in the slave's message queue will be sent to the
master and the master will route the messages that do not contain the master's
station code.
5.2.3 Module Data
All data related to the MVI46-DFCM module is stored in user defined data areas.
You must up the data areas to match the specific application for which the
module is used. Each data area is discussed below:
Configuration Data
You configure the module by entering values in a user defined data table. In the
example ladder logic, file N10 stores the general module configuration
information. N11 stores the command list for port 2. Each register in the files has
an associated symbol and description to help you enter the data. Refer to MVI46DFCM Configuration for the items that must be configured for the module, and
their associated location in the M0 file.
Backplane Parameters
All data transferred between the SLC processor and the module is held in the
module's M1 file. This simplifies the ladder logic. In order to read data in the
module, copy the specific data area in the M1 file into a user defined file. Repeat
this operation for each data area. Remember, the maximum data area that can
be copied with the COP instruction is 128 words. In order to write data to the
module, copy the data in the user defined file to the specific data area in the M1
file. The read and write data operations should be limited to the M1 words 0 to
4999. The modules status data can be read from the M1 file starting at register
7600.
Only two parameters are used in this section of the configuration. The Backplane
Fail determines if the module should continue communicating on the DF1
network when the backplane transfer operation fails. A value of zero indicates
that the module should continue communicating when the backplane is not
operational. If the value is greater than zero, the backplane will be retried the
entered number of times before a failure will be reported and communication will
cease on the ports. When backplane communication is restored, the module will
start communicating on the network. For example, if you enter a value of 10 for
the parameter, the module will stop all DF1 communications if 10 successive

October 20, 2008
MVI46-DFCM ♦ SLC Platform Reference
DF1 Communication Module
backplane errors are recognized. When a successful transfer is recognized, the
module will resume communications on the network.
The Error Status Pointer parameter defines the location in the module's database
where the error/status data will be stored. If the value is set to -1, the data will not
be stored in the user data area. A value between 0 and 4939 will cause the
module's program to store the data at the specified location.
Port Parameters
These parameters define the operation of each of the DF1 ports on the module.
Refer to MVI46-DFCM Configuration Data Definition for the definition of each
parameter.
DF1 Master Commands
These records define the commands in the master command list. The definition
of each parameter required for each command is given below:
Command Description
Enable This parameter defines if the command will be executed or will be disregarded. The following values
are valid: 0=Disables the command and it will not execute. 1=The command will be considered for
execution each scan of the command list and will be controlled by the PollInt parameter. 2=The
command will only execute if the data associated with the command has changed since the
command was last issued. This option is only available for write commands. 999=The command will
issue a poll command to the slave unit indicated in the command. This option is only valid for a halfduplex network.
IntAddress This parameter specifies the starting internal register address to be associated with the command.
Valid entry for this parameter is 0 to 9999.
PollInt This parameter defines the Minimum time in tenths of a second to wait between the execution of
continuous commands (Enable=1). This poll interval command can be used to lighten the
communications load on a busy network. Valid entry for this parameter is 0 to 65535.
Count This parameter defines the number of registers to be considered by the command. Valid entry for
this parameter is 1 to 100.
Swap This parameter specifies if the data used in the command must be altered when a reading data from
a node on the network. Values that can be assigned are as follows: 0=no swapping of data, 1=swap
word values, 2=swap word and byte values and 3=swap byte values. This option is used when
interfacing the module with ASCII and floating-point data on other devices.
Node This parameter assigns the DF1 slave node address for the module to reach with the command on
the network. This parameter can be assigned values from 0 to 255.
Func This parameter specifies the function to be performed by the command. Valid entries are those
defined in the DF1 Command Set for ProSoft Technology. Communication Modules document.
Parameter_1 to
Parameter_4
These are the parameters required for the selected function. Each command has its own unique set
of one or more parameters. Refer to the DF1 Command Set document for a complete list of
command parameters.
Status Data
This data area views the status of the module. Use this data to monitor the state
of the module at a "real-time rate". Refer to the Reference chapter for a complete
listing of the data stored in this object. This data can be read from the module's
M1 file starting at register 7600. User data file N30 is defined in the example
ladder logic for this purpose.
Page 70 of 103 ProSoft Technology, Inc.
October 20, 2008
Reference MVI46-DFCM ♦ SLC Platform DF1 Communication Module
User Data
All user data is stored in the module's M1 file in registers 0 to 4999. This 5000word area is directly accessible from the ladder logic. The COP instruction should
be used to move blocks of data between the user data files and the module's M1
file. This will limit the number of accesses to the M1 data area and provide faster
system response. In the example ladder logic, N31 holds data read from the
module, and N32 stores data to write to the module.
Slave Polling Control and Status
Two data areas can be allocated in the SLC to hold the polling status of each
slave on the master ports. This status data can be used to determine which
slaves are currently active on the port, are in communication error or have their
polling suspended and disabled. If the configuration supplies an address where
this data resides, copy the data from the M1 file to the reserved files in the SLC.
Using special blocks, the processor can enable or disable the polling of selected
slaves.
5.3 Cable Connections
The application ports on the MVI46-DFCM 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 requir e
hardware handshaking (control and monitoring of modem signal lines). Enable this in the
configuration of the module by setting the U seCTS 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:

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.

Reference MVI46-DFCM ♦ SLC Platform DF1 Communication Module
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.

5.3.3 RS-422
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 y ou 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.

5.4 MVI46-DFCM Command Control
Command Control data is received from other nodes on the network that can
control the MVI46-DFCM module. Specific values are written to regions of this
block to control the module. Currently, the module is programmed to handle the
receipt of the following requests: write configuration to processor, warm boot and
cold boot.
The remote node controls the module by writing one of the following values to
register 7800 (address N46:0):
9997 Write configuration in database to the processor and warm boot the module
9998 Warm boot the module
9999 Cold boot the module
The control register is cleared (a value of 0) after the operation is executed with
the exception of the 9997 command. If the module fails to successfully transfer
the configuration to the processor, an error code will be returned in the control
register as follows:
0 No error, transfer successful
-1 Error transferring general configuration information
Ladder logic must handle the 9997 command. No ladder logic is required when
using the warm or cold boot commands.

5.5 Error Codes
The module error codes are listed in this section. Error codes returned from the
command list process are stored in the command list error memory region. A
word is allocated for each command in the memory area. The error codes are
formatted in the word as follows: The least-significant byte of the word contains
the extended status code and the most-significant byte contains the status code.
Use the error codes returned for each command in the list to determine the
success or failure of the command. If the command fails, use the error code to
determine the cause of failure.
Note: The Module Specific error codes (not DF1 compliant) are returned from within the module
and never returned from an attached DF1 slave device. Th ese are error codes that are part of the
DF1 protocol or are extended codes unique t o this module. The standard DF1 error codes can be
found in the DF1 Protocol and Command Set Reference Manual (Publication 1770- 6.5.16) from
Rockwell Automation. The most common errors for the DF1 protocol are shown in the following

5.6 DF1 Command Set For ProSoft Technology Communication Modules
5.6.1 Introduction
This document contains a complete description of the command set required to
communicate with DF1 protocol devices using a ProSoft communication module.
ProSoft communication modules that contain a virtual DF1 master device use
this command set to control and monitor data in DF1 protocol devices. These
include Rockwell Automation PLC, SLC, MicroLogix and ControlLogix controllers
and field devices supporting the DF1 protocol. ProSoft supports the DF1 protocol
on both the serial and network interface. The network interface requires the use
of the port service address 0xAF12 as specified in the ControlNet Specification.
Rockwell Automation supports this feature in the ControlLogix 5550, PLC5 xx/E
and SLC 5/05 processors.
The ProSoft modules contain a virtual database that is defined by the user. This
database is used as the source for write commands and the destination for read
commands issued on the virtual DF1 master devices. The module interfaces data
contained in remote DF1 slave devices to the virtual database using the DF1
master. User commands are issued out of the DF1 master from a command list.
These commands gather or control data in the DF1 slave devices. The following
illustration shows the relationships discussed above:
Page 80 of 103 ProSoft Technology, Inc.
October 20, 2008
Reference MVI46-DFCM ♦ SLC Platform DF1 Communication Module
Each command issued from the DF1 master contains a field that indicates the
location in the virtual database to be associated with the command. Care must
be taken when designing a system to be sure the read and write data regions for
the database do not overlap for a single device. The read area of one device can
overlap the write section of another device to transfer the data from one slave
device to another.

5.6.3 PLC-5 Processor Specifics
This section contains information specific to the PLC-5 processor with relation to
the DF1 command set. The commands specific to the PLC-5 processor contain a
sub-element code field. This field selects a sub-element field in a complex data
table. For example, to obtain the current accumulated value for a counter or
timer, the sub-element field should be set to 2. The tables below show the subelement codes for PLC-5 complex data tables.

5.6.4 SLC Processor Specifics
This section contains information specific to the SLC processor based family
when used with the DF1 command set. The SLC processor commands support a
file type field entered as a single character to denote the data table to interface
with in the command. The following table defines the relationship of the file types
accepted by the module and the SLC file types:
SLC File Types
File Type File Type Command Code Description
S 83 Status
B 66 Bit
T 84 Timer
C 67 Counter
R 82 Control
N 78 Integer
F 70 Floating-point
Z 90 String
A 65 ASCII
The File Type Command Code is the ASCII character code value of the File Type
letter. This is the value to enter into the "File Type" parameter of the DF1
Command configurations in the data tables in the ladder logic.
Additionally, the SLC specific functions (502, 510 and 511) support a subelement field. This field selects a sub-element field in a complex data table. For
example, to obtain the current accumulated value for a counter or timer, the subelement field should be set to 2.

5.6.5 MicroLogix Processor Specifics
This section contains information specific to the MicroLogix processor based
family when used with the DF1 command set. The MicroLogix processor
commands support a file type field entered as a single character to denote the
data table to interface with in the command. This field is the same as that used
for a SLC processor. The following table defines the relationship of the file types
accepted by the module and the SLC file types:
SLC File Types

The File Type Command Code is the ASCII character code value of the File Type
letter. This is the value to enter into the "File Type" parameter of the DF1
Command configurations in the data tables in the ladder logic.
Additionally, the SLC specific functions (502, 510 and 511) support a subelement field. This field selects a sub-element field in a complex data table. For
example, to obtain the current accumulated value for a counter or timer, the subelement field should be set to 2.
5.6.6 ControlLogix Processor Specifics
This section contains information specific to the ControlLogix processor when
used with the DF1 command set. The current implementation of the DF1
command set does not use functions that can directly interface with the
ControlLogix Tag Database. In order to interface with this database, the tablemapping feature provided by RSLogix 5000 must be used. The software permits
the assignment of ControlLogix Tag Arrays to virtual PLC 5 data tables. The
ProSoft module using the PLC 5 command set defined in this document can then
reach this controller data.
