Typically ruggedized for use in the field or in a plant environment, OITs are continuously being improved to match the rich graphics and flexibility offered by HMI applications -- so much so that OIT and HMI are beginning to be used interchangeably. The GDS team has integrated OIT systems from a variety of OEMs such as Red Lion, Maple Systems, and Allen Bradley for past and current clients. GDS provides a full range of OIT integration services customized to meet your requirements.
