Module Power Up On power up the module begins performing the following logical functions:...
  • Page 67 Backplane Data Transfer The MVI56-DFCM 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.
  • Page 68 Data contained in this database is paged through the input and output images by coordination of the ControlLogix ladder logic and the MVI56-DFCM module's program. Up to 248 words of data can be transferred from the module to the processor at a time.
