Supervisory control and data acquisition system

The original WOA supervisory control and data acquisition system was configured around the Honeywell HS4400 process computer. Two 4400s in dual redundant processor configuration were installed with automatic failover to the standby should the online unit fail. Each 4400 has 96K of 24-bit word magnetic core memory and a 1.3 million word drum. 

Control System Included in this classification are Supervisory Control and Data Acquisition Systems (SCADA), Distributed Control Systems (DCS), Statistical Process Control systems (SPC), Programmable Logic Controllers (PLCs), intelligent electronic devices, and computer systems that control manufacturing equipment or receive data directly from manufacturing equipment PLCs.

To date, process control systems like Programmable Logic Controllers (PLCs) have only enabled paperless operation in combination with SCADA (Supervisory Control and Data Acquisition) systems or as part of a DCS (Distributed Control System), which enable measurement and control actions to be recorded and used as part of batch documentation. Process control systems have the advantage that they focus on real-time data as a necessary part of both control and supervision. The real-time focus is very useful for implementing both active and proactive control when combined with, for example, statistical tools or predictive algorithms.

Increasingly the senior technicians function as supervisors for computer control systems such as Distributed Control Systems (DCS) or Supervisory Control and Data Acquisition Systems (SCADA). These technicians need procedures that help them work with the electronic interface, generally as troubleshooters for when the electronic systems go awry, or for when the control systems fail.
