Process Control Systems

 Joe, a technical applications engineer at XYZ Energy Management Systems  Inc. has been asked to develop a direct digital control system for  environmental control and energy management in an office building. You  are asked to help him by developing a two-page, double spaced  description of direct digital control strategy. Your description must  provide detailed information, such as the definition, organization,  elements, functions, and benefits of direct digital control. 

 Direct digital control is the automated control of a process using a  digital device, such as a computer. This strategy is extensively used in  energy management systems in buildings. With direct digital control, it  is possible to control heating and cooling functions with software that  takes into account a wide range of variables, thereby achieving greater  efficiency. In this activity, you explore the organization, elements,  functions, and benefits of using direct digital control.
