The ABB Master System introduced in 1984 was based on MasterPiece 200 controllers with S100 Rack I/O along with the MasterView 800 operator interface with the high end Tesselator Display system. In 1988 the S400 remote I/O was introduced.
In 1992, the ABB Master system began its evolution to Advant OCS. This evolution introduced two high capacity controllers, AC450 and AC410, and the S100 rack mounted I/O featuring an improved redundancy scheme.
Also introduced were the state of the art operator interface, based on UNIX workstations, and in 1996 the S800 remote I/O, providing modular flexible remote I/O with redundant communication and a 1ms time stamp.
Remote EX S800 I/O and Profibus DP support for connection to third party sub systems was released in the late 1990s.
In 2004, Advant OCS with Master Software began its next step in the evolution process with the introduction of 800xA enabled products, 800xA for Advant master. ABB's commitment to protecting your investment continues with these enhancements by providing connectivity to our latest control offering.
