SIMATIC ET 200 System Benefits -
Safety Integrated
Until recently it has been common to implement safety tasks and standard
tasks using different systems. This led to discontinuous systems and
additional outlay. With SIMATIC, however, the safety system is directly
integrated into the standard automation. Apart from the hardware, assembly
and installation costs for separate safety wiring, Safety Integrated as a
system-wide solution also saves engineering costs because standard and
safety automation are configured in the same manner.
SIMATIC Safety Integrated includes the failsafe programmable controllers
SIMATIC S7-300F and S7-400F/FH as well as failsafe I/O and engineering
products within the range of Safety Integrated.
If a fault occurs, the complete programmable controller or a sub-process
can be transferred to and retained in a safe state. Distributed I/O systems
are used for distributed expansion of a failsafe programmable controller.
The failsafe SIMATIC ET 200 systems can be assembled as combinations
including both failsafe and standard I/O modules. The I/O spectrum ranges
from simple I/O channels through motor starters as far as frequency
converters.
Safety-related communication can take place in the same manner as standard
communication over the two PROFIBUS and PROFINET bus systems. These have
been expanded for failsafe communication by means of the PROFIsafe profile.
