ABB PFSA146 DSP signal processing module CPU module

Description

This Product Guide describes Safeguard 400 Series, controllers designed to monitor and control

safety aspects of an industrial plant. Safeguard 400 Series is derived from standard ABB control

products, which have been expanded, enhanced and configured to offer the necessary safety

functions. Hardware and software have been added, and configurations have been changed.

This Product Guide describes the Safeguard system, what it consists of, how it works in general,

and what software tools that are included in the portfolio.

1.2 General information

Many modern processing industries present hazards which pose major risks for workers,

machinery and the environment. At the same time, ever increasing demands are being made on

productivity and quality. These developments have led to more complex, more sophisticated

production systems, which in turn generate more process-related critical situations than ever

before.

Although the automation system in itself represents a high level of security, there is still a need

for superior safety systems exclusively dedicated to further reducing risks, and minimizing the

effects if something should go wrong. These safety systems have two major tasks:

• Preventing the process from entering an unsafe state
• Re-establishing a safe state of the plant, or reduce the consequences and protect personnel,

if the process for any reason has reached an unsafe state (e.g. gas leaks caused by pipe

rupture)

Safeguard is a fault-tolerant safety system especially designed for the protection of industrial

processes. Based on ABB’s family of micro-computer based controllers and networks, it offers

high reliability control and supervision in process applications such as Emergency Shutdown

(ESD), Process Shutdown (PSD), Equipment Protection, Critical Control and Fire & Gas

Protection (F&G) systems.

Important characteristics of this system are:

Safety and reliability

Safeguard 400 Series is based on Advant Controller 410 and is extended with software and

hardware for handling safety signals, test, monitoring and advanced diagnostics. It adds an

advanced output voting unit called Master Vote 3000. A single failure in the system will not

prevent a pre-defined safety action from being executed.

Availability and fault tolerance

A combination of output voting, testing and monitoring detects and isolates faulty components

in the system. Safeguard offers fault tolerance for critical single faults, and fail-to-safe action

for multiple faults. This ensures high availability through error-free, uninterrupted process

operation, while preserving a high reliability in safety operations.
