Profile: Emmeskay, Inc. specializes in state-of-the-art technology products and services. Our product line includes control systems, plant modeling, tools, verification & validation code and application domain. Our variety of business and market drivers have led to explosive growth in the complexity and frequency of use of electronic controls in engineered products. Our model-based system development (MBSD) is now practised by large groups of engineers, distributed across organizations and geographies. In this context, the ability to do concurrent engineering, distributed development and model reuse are major enablers for effective and efficient use of MBSD processes in large organizations. Our controller communication tool box provides an easy-to-use interface between MATLAB® running on an automation system (AUSY) & calibration software running on a measurement and calibration (MC) system, through a serial link using the ASAP3 protocol. This tool box is typically expected to be used in a HIL set-up to communicate and automate calibration or verification, and validation of the ECU.
