Backplane Data Transfer The MVI69E-MBS module communicates directly over the CompactLogix or MicroLogix 1500-LRP backplane. Data is paged between the module and the CompactLogix or MicroLogix 1500-LRP 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 that you define for the module and the communication load on the module. Typical updates are in the range of 1 to 10 milliseconds per block of information. This bi-directional data transfer 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, 122, or 242 words depending on the block transfer size parameter set in the configuration file. This data area permits fast throughput of data between the module and the processor. Applications that require smaller amounts of data or faster update times, such as ControlNet networks, will benefit from smaller block transfer sizes. 
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, 121, or 241 words depending on the block transfer size parameter set in the configuration file. The following illustration shows the data transfer method used to move data between the CompactLogix or MicroLogix 1500-LRP processor, the MVI69E-MBS module and the Modbus Network.

Page 68 of 159 All data transferred between the module and the processor over the backplane is through the input and output images. Ladder logic in the CompactLogix or MicroLogix 1500-LRP processor interfaces the input and output image data with data defined in the Controller Tags. All data used by the module is stored in its internal database. This database is defined as virtual MBS data tables with addresses from 0 to the maximum number of points for each data type.
