Flexible Modular Redundancy
Single design controllers
 |
SIMATIC S7-400F (large image) and
S7-300F (small image) safety controllers are used for the
implementation of standard and safety automation.
For use as safety controller, the user can expand the standard CPU
to include safety-relevant functions with the S7-F Systems software
package.
This makes it possible to integrate our safety-technology
and the standard SIMATIC automation into one system.
|
Four CPUs are available for both the SIMATIC S7-400F
and for the S7-300F, to suit different performance requirements. The most
important characteristic data are shown in the overview of CPUs,
below.
| Benefits
of safety controllers from Siemens: |
 |
Coexistence of standard and safe program
in one CPU possible |
|
SIL 3 can be met only with one controller |
|
Very easy integration of the SIMATIC
fail-safe controllers with
 SIMATIC
PCS 7 |
|
Easy programming with
CFC
(Continous Function Chart) and
Safety
Matrix (cause & effects method)
 |
|
The safe, fault-tolerant SIMATIC controllers
fulfill the demands of the highest safety level:
| - |
IEC 61508 (up to SIL 3)
|
| - |
EN 954 (up to Category 4)
|
| - |
TÃV-certificate no: Z2 03 04 38282 002
