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 (15 for the PC56). When
the battery is fully discharged, the module will revert to the default BIOS settings.

Note: The battery is not user replaceable.

implement. Go to the Ladder Logic section for a complete discussion of the
ladder logic requirements.

2.1 Initial Processor Ladder File Setup

Processor communication to the MVI56-PDPS module requires configuration
using the RSLogix 5000 program. The quickest way to configure the module is to
start with the example provided with the module () and the default PDPS
configuration file. If you are installing this module in an existing application, you
can copy the elements required from the example ladder logic to your
application.

Note: The module can only be added to a project us ing the software in offline mode.

The first step in setting up the processor ladder file is to define the I/O type
module to the system. Click the right mouse button on the I/O Configuration
option in the Controller Organization list to open a shortcut menu. Select the New
Module… option from the I/O Configuration menu:

This action opens the following dialog box.

Select the 1756-Module (Generic 1756 Module) from the list and click OK. The
following dialog box is displayed.

Fill in the dialog boxes as shown adjusting the Name, Description and Slot
options for your application. You must select the Comm Format as Data - INT in
the dialog box. Failure to set the Assembly Instance and Size values correctly
will result in a module that will not communicate over the backplane of the
ControlLogix rack. Click Next to display the next dialog box:

Select the Request Packet Interval value for scanning the I/O on the module.
This value represents the minimum frequency the module will handle scheduled
events. This value should not be set to less than 1 millisecond. Values between 1
and 10 milliseconds should work with most applications.

After completing the module setup, the Controller Organization list will display the
module's presence. The data required for the module will be defined to the
application, and objects will be allocated in the Controller Tags data area. An
example of the Controller Organization list follows:

The next step in the module's setup is to define the User Defined Data Types to
be used with the module. Copy these data types from the example ladder logic if
you are not using the example. They will be defined if you are starting from the
example ladder logic. The Controller Organization list should display the User
Defined Data Types shown in the following example:

The next step in module setup is to define the data to be used to interface with
the module and the ladder logic. Open the Controller Tags Edit Tags dialog box
and enter the values shown in the following example. The MVI56-PDPS module
is defined in the example as PDPS. You can set the tag name to any valid tag
name you desire. If you are using the example ladder logic, this step has already
been performed.

At this point, take the time to adjust the array sizes PDPS data table for the read
and write data. The last step is to add the ladder logic. If you are using the
example ladder logic, adjust the ladder to fit your application. If you are not using
the ladder example, copy the ladder logic shown in the Controller Organization
list shown to your application.

It is now time to edit the PDPS.CFG file to set up the module for the specific
application. Refer to the Configuration File section of this document. The
module is now set up and ready to use with your application. Insert the module in
the rack and attach the PROFIBUS cable. Download the new application to the
controller and place the processor in run mode. Download the new PDPS.CFG
file to the module using HyperTerminal. If all the configuration parameters are set
correctly and the module is attached to a network, the module's Application LED
(APP LED) should remain off and the backplane activity LED (BP ACT) should
blink very rapidly. If you encounter errors, refer to Diagnostics and
Troubleshooting (page 41) for information on how to connect to the module's
Config/Debug port to use its troubleshooting features.

2.2 Module Data Object

All data related to the MVI56-PDPS module is stored in a user defined data type.
An instance of the data type is required before the module can be used. This is
done by declaring a variable of the data type in the Controller Tags Edit Tags
dialog box.

The structure of the object is displayed in the following figure:

This object contains objects that define user and status data related to the
module. Each of these object types is discussed in the following topics of the
document.

2.2.1 Status Object (PDPSInStat Data Structure)

This object views the status of the module. The PDPSInstat object shown below
is updated each time a read block is received by the processor. Use this data to
monitor the state of the module at a "real-time rate".

Refer to Status Data Definition for a complete listing of the data stored in this
object.

2.2.2 User Data Objects

These objects hold data to be transferred between the processor and the MVI56­PDPS module. The user data is the read and write data transferred between the
processor and the module as "pages" of data up to 200 words long.

The read data (ReadData) is an array set to match the value entered in the Read
Register Count parameter of the PDPS.CFG file. This data is paged up to 200
words at a time from the module to the processor. The ReadData task places the
data received into the proper position in the read data array. This data will be
data sent to the module by the PROFIBUS Master (PROFIBUS Outputs) and can
be used for status and control in the ladder logic of the processor.
