Fail-safe S7-300 CPU
Description
The fail-safe SIMATIC controllers are used to guarantee the functional safety of machines or plants. They satisfy maximum safety requirements and comply with the relevant standards:
EN 954-1 up to Cat. 4, IEC 62061 up to SIL 3 and EN ISO 13849-1 up to PL e.
The simultaneous processing of the standard and the safety program means that only one CPU is required to handle both tasks.
Area of application
-
Automobile industry
-
General mechanical engineering
-
Building of special machines
-
Series mechanical engineering, OEM
-
Plastics processing
-
Packaging industry
-
Food- and Beverageindustry
Benefits
Reduction of stock-keeping by saving components
-
One controller for standard and safety automation
- Coexistence of standard and safety programs on one controller possible -
One PROFIBUS or PROFINET transmitting medium for standard and safety communication to SIL 3/Category 4
- One distributed I/O configuration with standard and safety I/O modules
Fast system configuration and commissioning
-
Better system integration
- Uniform engineering for standard and safety control component
- Use of existing PROFIBUS or PROFINET transmitting medium even for safety
communication
- Simple expansion of existing PROFIBUS archtictures about PROFINET, p.ex. via IE/PB-Link
(SIMATIC NET)
More flexibility
-
The logic of the safety functions is software-based rather than hard-wired
- More easily modified, expanded and documented
- Implementation of complex safety functions
Faster reproducibility
-
In contrast to the hardware solution, the software solution can be easily reproduced
-
Approved, certified solutions can often be used as self-contained blocks
Better retent of plant availability
-
Early fault detection thanks to better diagnostic functions
Investment security
-
Easy migration from PROFIBUS to PROFINET
Area of application
Because of their power and compactness, the safety SIMATIC S7-300F CPUs are ideal for meeting the demands of the mid to upper performance range. Both standard and safety-relevant tasks can be performed with only one CPU.
The SIMATIC S7-300F CPUs can be expanded centrally with the safety modules for the ET 200M I/O. Distributed expansion is possible using the safety ET 200S I/O modules, the ET 200M I/O modules, the ET 200pro (IP67) I/O modules or the safety digital block peripheral device ET 200eco (IP67).
Communication works depending on the CPU optional via MPI, PROFIBUS or PROFINET Interface.
