Integrated Safety Management

Your Benefits

Know in Advance

Keeping your operators fully aware of events as they occur

A traditional emergency shutdown (ESD) system enables reactive protection under emergency conditions, but offers little help to operators and provides little synergy with production control systems.

A better solution is to integrate safety information and enable seamless monitoring and prediction of critical conditions, opening the path back to normal conditions while securing safety loop integrity.

Conventional ESD system:

ProSafe-RS Safety Controller:

- Dedicated human machine interface (HMI), dedicated network, dedicated database

- Enables safety personnel to analyze events retrospectively, but realtime information monitoring through control systems is cumbersome, slow, and limited

- Information integration:
Common human machine interface and unified event data enables integrated safety management

Alerts operators of critical conditions before they reach emergency

- Safeguarding:
Ensures SIL3 protection in case the process reaches emergency conditions

BEFORE: Safety personnel analyzes emergency events retrospectively, consulting the dedicated ESD system database

AFTER: Operators are alerted of ciritical conditions in advance via common HMI; enables effective decisions to avoid/minimize emergency

The Know in Advance Advantage

The new groundbreaking ProSafe-RS safety controller ensures a seamless integration of your control system and emergency shutdown system, keeping your operators fully informed of unfolding events. Singlewindow operation through common HMI enables your operators to make effective decisions that bring the process back to a normal condition. The integrated solution helps the operators to minimize hazard even in case of emergency shutdown.
