What are the differences between the Rockwell 1756-MVI and the MVI56-ADM module?

The MVI56-ADM is essentially the same product as the 1756-MVI.  The 1756-MVI (and MVID) are no longer sold by Rockwell Automation. ProSoft's MVI56-ADM has additional libraries that were not available from Rockwell for the 1756-MVI. These libraries assist the user in setting up a database, debug port, and accessing the backplane and serial ports.  The .ima image file is attached to this entry.

Note:  For simple ASCII communications, such as reading/writing to/from devices such as scales, barcode scanners, serial printers, etc., we strongly recommend you consider the MVI56E-GSC (serial) or MVI56-GEC (Ethernet).
