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.

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 5000 to identify the module to the processor and add the

module to a project.

Note: The RSLogix 5000 software must be in "offline" mod e to a dd 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 a pplication, 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.

2.1 Installation Instructions

The following setups/limitations are to be observed:

Please make sure that you are using an MVI56-S3964R with the original

parameters and image as delivered. Jumper SETUP: Please remove to run the MVI56-S3964R in application mode.

ATTENTION: Incorrect setting of the jumpers may cause damage to the MVI56-S3964R module.

The remaining jumpers for PRT1 and PRT2 have to be set according to the requirements of the user.

The communication partners are to be connected to the serial interface PRT1 and/or PRT2 of the

The serial parameters of the communication partners are to be set to 9600 Baud, even parity, 8 bit and 1 stop bit if the standard parameters of the S3964R

will be used.

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 window should display the User Defined Data Types shown below:

After you have defined the User Defined Data Types, the next step 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-S3964R module is defined in the example as S3964R. 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.

2.1.1 Module Data Object

All data related to the MVI56-S3964R 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.
