5.2 Functional Overview
5.2.1 Backplane Data Transfer
The MVI56E-MNETC/MNETCXT module communicates directly over the
ControlLogix backplane. Data is paged between the module and the ControlLogix
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
defined by the user for the module and the communication load on the module.
Typical update times range from 1 to 10 milliseconds.
This bi-directional transfer of data is accomplished by the module putting data in
the input image to send to the processor. Data in the input image is placed in the
processor's controller tags by ladder logic. The input image is set to 250 words.
Processor logic inserts data to the output image to be transferred to the module.
The module's firmware program extracts the data and places it in the module's
internal database. The output image is set to 248 words.
