The MVI ADM API Suite allows software developers to access the PLC
backplane and serial ports without needing detailed knowledge of the module’s
hardware design. The MVI ADM API Suite consists of three distinct components:
the Serial Port API, the MVI Backplane/CIP API and the ADM API.
 The MVI Backplane API provides access to the processor
 The Serial Port API provides access to the serial ports
 The ADM API provides functions designed to ease development.
 In addition to the MVI Backplane API, MVI71 also provides the MVI Side-
Connect API as an alternative interface.
Applications for the MVI ADM module may be developed using industry-standard
DOS programming tools and the appropriate API components.
This section provides general information pertaining to application development
for the MVI ADM module.
