This was possibly the first successful implementation of a distributed processing direct digital control system.

Integrated Web based direct digital controls system and pervasive voice/data/video system with kiosk displays.

The patent that issued after the decision was , "Direct digital control of rubber molding presses."

Some of the central plant projects also include the installation of direct digital controls [1].

Historically, pneumatic control was commonplace, but electronic direct digital control systems are popular especially for mid-to-large size applications.

Midac Systems, of Sydney, Australia, developed an objected-oriented distributed direct digital control system in 1982.

Central controllers and most terminal unit controllers are programmable, meaning the direct digital control program code may be customized for the intended use.

In the 1990s, the standard became microprocessor-based direct digital controls that process a variety of analog and binary inputs and outputs.

Computers had already been applied to process automation for some time in the form of both direct digital control (DDC) and set point control.

Direct digital control (DDC) is the automated control of a condition or process by a digital device (computer).

In this way the Trickstick combines the proportional control of the analogue joystick with the fast direct digital control of a switch-based unit.

In 2009, the AOC began retiring the original Energy Management Control System, replacing it with a new advanced direct digital control system.

It develops technology to centrally control and manages HVAC, refrigeration and lighting for businesses, including direct digital control and energy management.

The contract also specifies upgrading existing pneumatic and electric controls for heating, ventilating and air-conditioning (HVAC) systems with direct digital controls.

The PC became the interface that replaced the central console control, distributed direct digital control replaced conventional control systems, and communication could be programmed to take place on local area networks.

As well as general 120-240 volt electrical systems, the students also work on and learn about fire alarm systems, telephone systems, data/communications, and direct digital control systems for HVAC control within buildings.

Building and central plant operations are now relying heavily on direct digital controls; and as such the engineer is required to be much more computer literate to work with the BAS (Building Automation System).

Direct digital controls (DDC) with real time monitoring and history provide the ability to acquire system data realtime or with trend-logging, or trending, (over a predetermined period of time) to observe performance, issues/troubles, and identify possible improvements to operations and maintenance.

The contract also includes upgrading existing pneumatic and electric controls for heating, ventilating and air-conditioning (HVAC) systems with direct digital controls and providing an ongoing program to train building automation system operators specifically in the monitoring and diagnosis of energy-related controls deficiencies.
