Flexible Modular Redundancy™
Single design - I/Os
 |
With
SIMATIC ET 200, a whole
range of distributed I/O systems is available for the distributed
expansion of the SIMATIC safety controllers.
PROFIBUS and the PROFIsafe profile are used for communication.
Both safety-oriented and standard communication are possible in
this way via one and the same cable.
|
The fail-safe I/Os are internally redundant, can
diagnose internal and external faults and carry out numerous self-tests
and field-wiring diagnostics (e.g. short-circuiting, wire break).
| The fail-safe
SIMATIC I/O fulfill the demands of the highest safety level: |
 |
Communication via PROFIsafe (IEC
61508) |
 |
Up to SIL 3, TÜV certified (no:
Z2 03 04 38282 002) |
 |
Highest safety level
| - |
Self-diagnostics and signal test (short-circuit, wire break)
without additional programming overhead |
|
 |
Reduced engineering overhead
| - |
Fail-safe shutdown without additional safety relays |
|
 |
Cost reductions through
savings on materials
| - |
Coexistence of standard and fail-safe modules
in one station |
|
 |
Space-saving design
| - |
Connection of standard and fail-safe I/O using
just one PROFIBUS cable |
|
 |
Use of existing network infrastructure |
