Process Safety with

SIMATIC Safety Integrated

A safe bet: highly available operation

without any weak links

Process automation, with its extremely complex sequences, cannot afford to have any weak

links in the chain. Downtime and faults may have devastating effects – for people, equipment,

plants and the environment. To eliminate the source of hazards and minimize risks, you need

to have reliable safety technology for your processes that meets even the most stringent

demands: the Safety Instrumented System (SIS) of your choice should be reliable, flexible

and easy.

Reliable in eliminating risks – without stopping production.

Flexible offering flexible redundancy options and scalable architecture to economically

meet your requirements.

Easy to implement, operate and maintain.

Seamless safety technology ...

SIMATIC® Safety Integrated is a comprehensive

product range of safe, fault-tolerant and highly

available products for the process industries.

Siemens safety systems enable early detection of

critical signals, processing of those signals within a

predefined logic and execution. It offers one of the

most integrated systems available today, bridging

the gap with regards to engineering and communi-

cation tools over other conventional offerings.

... completely integrated into standard

automation

The SIMATIC S7-400FH automation system provides

the right mix of distributed I/Os to ensure maximum

safety, fault tolerance and availability for your appli-

cations. In combination with the SIMATIC PCS 7

process control system, you can realize powerful,

flexible solutions for integrated automation and

safety applications in one, integrated automation

network.

Part of Totally Integrated Automation

With Totally Integrated Automation, Siemens is the

only provider of an integrated range of products,

systems and solutions for automation in all sectors

of industry – from inbound logistics to outbound

logistics, from the field level to the manufacturing

execution level to the corporate management level.

One part of Totally Integrated Automation is SIMATIC

Safety Integrated.

Something you can rely on

For more than 20 years, we have been a reliable

industry partner for first-class automation solutions

for process safety – in a wide range of applications.

Typical safety applications include fire and gas,

burner management, emergency shutdown and

critical process control systems. Our solutions are

designed to minimize engineering effort, enabling

you to lower your overall cost for meeting safety

requirements. Our solutions comply both with

applicable national and international standards

such as IEC 61508 (to SIL 3), ISA S84, EN 54,

NFPA 85, API 14C and IEC 61511.

A safe bet: reduced life cycle costs

without compromise

You expect a modern Safety Instrumented System (SIS) to consistently reduce the probability of dangerous

risks and to reliably execute safety-related functions. In addition, you expect redundant, fault-tolerant systems

to ensure process availability without downtime. Just as important is reliable self-detection of internal faults

and a guaranteed safe system state. In the unlikely event of a system fault, the diagnostic tools immediately

detect and localize the fault for quick repair. Although safety and reliability are the highest priority, economic

aspects of the solutions certainly play a big role in your decision.

Maximum system availability

SIMATIC Safety Integrated offers systems with both

single and redundant design. Redundant systems

provide you with maximum availability for your

equipment and plants right from the start. Our safety

systems ensure minimum unplanned downtimes

during operation and, accordingly, lower life cycle

costs. The safety-certified modules are completely

redundant internally, feature a diverse design and

can diagnose internal and external faults quickly

and effectively.

Saves costs, space and installation overhead

With SIMATIC Safety Integrated, you benefit from

considerable savings potential – in different ways.

Thanks to the coexistence of standard and safety

I/O modules in one system, you can cut down the

number of hardware components, save separate

wiring and reduce cabinet space. That saves the

amount of spare parts you need to have on hand.

Since you can use the proven PROFIBUS standard

for safe communication by utilizing the certified

PROFIsafe profile, you no longer need a separate

safety bus.

More flexibility

The modular design of SIMATIC Safety Integrated

provides a high degree of flexibility allowing for

future modifications and expansions. Depending

on your requirements, the distributed I/O modules

can be equipped or expanded to include standard

and safety I/O modules and can be combined in the

same station or separately. The system can be con-

figured for SIL 2, SIL 3 or a combination of SIL 2 and

SIL 3. This flexibility provides cost savings for appli-

cations with a combination of SIL requirements.

Greatly simplified engineering

SIMATIC Safety Integrated makes engineering

much easier. You benefit from engineering tools,

system diagnostics and operator interfaces. You

can configure your safety functions for the SIMATIC

S7-400FH using our intuitive function block pro-

gramming tool Continuous Function Chart (CFC)

or the SIMATIC Safety Matrix for even more bene-

fits. This easy-to-use configuration tool automat-

ically generates complex safety programs based

on a cause & effects matrix, where the cause and

effects are easy to link. That means you can con-

figure your safety logic much faster than before.

Easy integration into the process control system

You can connect our innovative Safety Integrated

System – SIMATIC S7-400FH and SIMATIC ET 200M/S

to any distributed control system (DCS). One of the

unique features is the integration of safety functions

into the SIMATIC PCS 7 process control system. This

combination also provides you with a number of

benefits:

One engineering system for process control and

process safety applications

Common controller platform for both process

control SIMATIC PCS 7 and process safety

User-friendly display of process safety informa-

tion integrated into the operator interface of

SIMATIC PCS 7

Automatic integration of safety-related diagnostics

into the operator interface, with time stamp

Straightforward and seamless communications

between the DCS and SIS
