Performance/ availability

Key process values (normal operation)

e.g. group control

Level 4 Functional aspects

• Topology-oriented and task-oriented plant hierarchy (level 1 - level 3)

• Significance of level 2, more displays, mainly used for monitoring but also for controlling

• Several detailed views on the same plant section, mainly used temporarily for start-up, diagnostics etc.

Flexible Modular Redundancy ™

Flexible Redundancy at all levels • Scalable for different applications

(ESD, HIPPS, F&G etc.) • Controller redundancy for availability

.. not required for safety • Physical separation to combat

common cause • Flexibility to accommodate different

SIF architectures so … • Field device redundancy can be

designed to achieve safety and availability goals

• I/O redundancy independent of CPU

Design & engineering performance Integrated safety lifecycle tools

SIMATIC Safety Matrix



The realization phase

• The SIMATIC Safety Matrix as engineering tool • Configuration of the safety functions using

the Cause & Effects method • Automatic TÜV-certified creation of the Safety Logic

from the Cause & Effect matrix • Easy configuration without special

programming knowledge • Online monitoring mode for verification and validation

• Reduces systematic errors • Simplifies engineering, verification and validation • Saves time, improves safety



Operation & maintenance, modification • Online view of the signal status, Cause & Effects

Automatic integration in PCS 7 • First up alarm display and storage • Supports operator bypass, reset, override

and parameter changes • Sequence of event recording • Automatic report of operation functions • Automatic version tracking • Automatic documentation of changes

• Reduces systematic errors • Simplifies engineering, verification and validation • Improves operator efficiency • Saves time, improves safety


Decentralized automation for the hazardous area SIMATIC ET 200iSP

Failsafe modules for SIMATIC ET 200iSP Features • 3 failsafe modules to install directly

in Ex-zone 1/21; up to SIL 3, PLe • Digital Input Module F-DI8 NAMUR • Digital Output Module F DO4, 17,4V DC 40mA • Analogue Input Module F-AI4 HART

Customer benefits:

• Reduced installation effort by using ET 200iSP compared to traditional solutions (with Ex barriers) • Line monitoring up to sensors • SIL calculation advantages (no Ex barriers) • Complete portfolio - failsafe protection in Ex-Zone 1 especially for applications like ESD

(Emergency Shut Down), boiler protection (e.g. at biogas plants), fire-extinguishing system or gas / fire detection


Selected instruments pressure, temperature, level, Valve positioners, analysers
