DCS HCI (human-centered interface)

Promote prompt situational awareness and swift comprehension and decision-making, and also provide guidance for correct operation: that is the concept behind the “human-centered interface” of Azbil’s DCS.

Window-Set Call-up (for standardized operation views)

Combinations of windows required for operation or monitoring can be registered and called up as sets. This eliminates differences between operators’ views caused by differences in the screens that are displayed.

Multi-Information Window (preventing accidental oversights)

Windows are laid out in divided panes. Since information cannot be missed due to overlapping windows, this feature contributes to safe operation.

Easy Engineering Tool

The function design tool RTC(*1) makes design, maintenance, and modification of the control system easy. This tool provides extensive online help, graphics-based process control design, operation checks using smart simulation, and remote engineering
(*1Real Time CoSEE).

Highly Reliable Triple-Redundant Process Controller

Three CPUs (2-out-of-3 logic)
Three constantly synchronized CPUs perform calculations which are compared before outputting the results, helping in improved reliability.

Seamless backup
Unlike standby redundancy systems, there is no delay or wait time when switching from primary to standby unit. As a result, the system provides peace of mind for processes with fast responses and processes where safety is paramount.

Online maintenance
In addition to redundancy, all modules can be hot-swapped, allowing maintenance without interrupting plant operation.

What is the Early Warning System for Time Series Data?

A software system that predicts the future course of critical process variables and constantly monitors them to make sure they have not deviated from control values.
The Early Warning System for time series data provides easy automatic monitoring of critical process variables, predicts future fluctuations, and visualizes predicted future fluctuations in a trend graph.
If the system predicts that future fluctuation will reach a critical control value (a value at which a protective device is activated, a value set as a design limit, etc.), it issues a predictive alarm to make the operator aware of the situation.
The Early Warning System also helps operators to respond appropriately well in advance by displaying predicted future trends and time of occurrence.

Three important merits of the Early Warning System

• Constantly monitors/predicts trends even though the operator’s attention has slackened, and enhances the operator’s ability to notice abnormalities.
• Enables the operator to respond calmly well in advance, because the system displays the predicted time when the control value will reach the alarm threshold.
• Enables detection of fluctuations that cannot be detected by the DCS alarm system.

Features

• The Early Warning System automatically collects data on the monitored variables and predicts the future course of single variable data based only on that data using the Azbil’s logic.
• By capturing sudden fluctuations or trends worsening for a second time in critical process variables that cannot be detected by the DCS alarm system, the Early Warning System enhances the operator’s ability to notice abnormalities.
• The system continuously monitors up to 160 critical process variables while predicting their future movement to reduce the monitoring burden of operators.
• The Early Warning System is a software application that is independent of the DCS. At a site where DCS alarm management is not in place and DCS alarms are frequently issued, it is sure to provide the operator and other staff in the control room with the desired level of awareness.
• With its automatic display function and large display, the Early Warning System helps every staff member in the control room solve problems through teamwork.
