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.

In This Chapter
Module Configuration ............................................................................21
MVI46-DFCM Configuration ..................................................................21
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.

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.
Valid value in the range of 0 to
65535.
This parameter sets the address
in the internal DF1 database
where the command error data
will be placed. If the value is set
to -1, the data will not be
transferred to the database. Valid
value of 0 to 4999.
This parameter represents the
message response timeout
period in 1-ms increments. This is
the time that a port configured as
a master will wait before retransmitting a command if no
response is received from the
addressed slave. The value is set
depending upon the
communication network used and
the expected response time of
the slowest device on the
network.
This parameter specifies the
number of times a command will
be retried if it fails. Valid value in
the range of 0 to 10.
This parameter specifies the
number of polls to be skipped on
the slave before trying to reestablish communications. After
the slave fails to respond, the
master will skip commands to be
sent to the slave the number of
times entered in this parameter.
Valid value in the range of 0 to
65535.
This parameter specifies the
starting address in the virtual
database where the 256 slave
status values will be written. If the
parameter is set to -1, the slave
data will not be placed in the
database. Valid value in the
range of -1 to 4743.

This parameter is used when a
request for a file is received on
the communication port. This field
is required when responding to
PLC5 and SLC DF1 commands.
Use this parameter to define the
virtual file(s) to be simulated on
the module. This value is fixed at
7 for N7.
This parameter specifies the size
of each file to be simulated on the
module. All files simulated are
defined to have the same
assigned size. This value is fixed
at 200.
This parameter sets the database
register location of the first
element in the first file simulated
in the module. All offsets in the
first file and subsequent files will
be computed using the address
specified. This value is fixed at 0.
Therefore, the module assumes
N7:0 starts at the database offset
of 0 and each file is 200 words in
size.

This parameter defines if this port
will be utilized. If the parameter is
set to 0, the port is disabled. A
value of 1 will enable the port.
This parameter defines if the port
will emulate a master or slave
device. Enter 0 to emulate a
master device and 1 to emulate a
slave device.
This parameter specifies the local
station ID for all DF1 messages
sent from this master port. A
value of 255 is not permitted as
this is the broadcast address.
Valid value in the range of 0 to
