|- Standard IBM PC/AT (DOS/V) compatible workstation or server:
- Windows 2000, 2003, and XP are now supported. Windows 2008 and Vista support will be added in 2009.
- For more detailed information, please download the corresponding General Specifications sheet from our website.
|3. Are APC software packages capable of implementing multiple controller instances within the same environment?|
- Exasmoc (Yokogawa Multi-variable Optimizing Controller) is composed of multiple main controllers, with each of these having its own sub-controllers. A main controller can share the control results with its sub-controllers. A sub-controller corresponds to a conventional model predictive control (MVC) controller.
- Exarqe (Yokogawa Robust Quality Estimator) is composed of multiple estimators. Each estimator has multiple predictors.
