Benefits

Safety Integrated for Process Automation permits complete inte-

gration of safety engineering into the SIMATIC PCS 7 process

control system. The Basic Process Control System (BPCS) and

Safety Instrumented System (SIS) melt together into a uniform

and innovative complete system. The advantages of this fusion

are quite clear:
• One common controller platform
• One common engineering system
• No separate safety bus - standard and safety-related commu-

nication take place on the same fieldbus (PROFIBUS with

PROFIsafe)

• Mixed operation of standard and safety-related I/O modules in

ET 200M and ET 200S remote I/O stations

• Uniform data management - no complex data exchange be-

tween BPCS and safety system

• Integration of safety-related applications into process visual-

ization on the operator station

• Automatic integration of safety-related fault messages with

time tagging into the process control system

• Integration of safety-related hardware into the SIMATIC PCS 7

asset management for diagnostics and preventive mainte-

nance

The SIMATIC PCS 7 engineering system is a universal tool

equally suitable for BPCS and safety applications.
Using the S7 F Systems engineering tool, you can parameterize

the AS 414F/FH and AS 417F/FH automation systems as well as

the safety-related F-modules of the ET 200M and ET 200S I/O

systems.
Using Continuous Function Chart (CFC) and predefined function

blocks from the F-block library of S7 F Systems, you can config-

ure safety-related applications simply, efficiently and without

weary acquaintance.
However, this is even simpler, more convenient and faster using

the SIMATIC Safety Matrix based on CFC. The configuration tool

functioning according to the principle of a Cause&Effect matrix

automatically creates complex safety programs once you have

assigned the events (causes) occurring during a process to ex-

actly defined reactions (effects).
