SIMATIC Fail-safe I/O systems
Machine safety in a distributed configuration
The modular design allows you to easily scale the SIMATIC ET 200 systems in small steps, for example, to expand with fail-safe I/O modules. The products can be consistently integrated into the automation system using PROFINET and/or PROFIBUS via PROFIsafe. All fail-safe I/O modules are certified for use in applications in accordance with IEC 62061 up to SIL 3 and EN ISO 13849-1 up to PL e.
Safety Evaluation with TIA Selection Tool
You can have it both:
Configure and order your I/O systems with the TIA Selection Tool and use the same tool for your safety evaluation.
Safety Evaluation with TIA Selection Tool makes it even faster and more convenient to draw up proofs of safety in accordance with IEC 62061 and ISO 13849-1.
The I/O systems in detail
SIMATIC ET 200SP - Greatest variety of modules, performance and usability also for safety-related applications
The finely graded modular system with protection rating IP 20 is characterized by a comprehensive range of failsafe modules. Starting with modules that acquire encoder signals or modules to connect actors the portfolio also comprises intelligent modules for safe pre-processing of data, e.g. the new fail-safe counter module.
Fail-safe digital signal modules F-DI /F-DQ
The fail-safe modules for digital in- and outputs (DI/DQ) correspond to the size of the standard modules. Functional safety is certified according to EN 61508.
They are designed for safety-related use up to SIL 3 according to EN 62061 and PL e according to ISO 13849. One special feature of the F modules of SIMATIC ET 200SP is that the F addresses are assigned via the engineering during commissioning. This simplifies the setup process and saves time.
The portfolio comprises one fail-safe digital IO module and two output modules all in High Feature function class.
Another Standard digital output module with a relay output completes the offer.
Fail-safe analog inputs (F-AI)
There are two fail-safe analog input modules for connecting current and voltage sensors for measuring temperature, pressure, flow, level, distance measurement, etc.
Both are High Feature modules that support the diagnosis of wire break, short circuit, high/low limit violation and allow channel- or module wise passivation.
Fail-safe counter module (F-TM Count)
The F-TM Count module acquires and evaluates the signals from one incremental rotary encoder (sin/cos 1Vpp). Besides the counting function, the module provides several integrated safety function like SLS (Safely Limited Speed), SOS (Safe Operating Stop) and SDI (Safe Direction). In case a limit has been violated, the module provides this information to the F-PLC. Counting values can be provided as “raw” values or in units like velocity, frequency, or cycle duration.
F-PM-E 24VDC/8A PPM
With the fail-safe SIMATIC ET 200SP power module, safety-related groups of standard or fail-safe DQ modules can be switched off.
The safety functions are then evaluated either in the F-CPU or in the F-PM-E power module as desired. This fast and direct group switch-off takes place up to SIL2 / PL d or SIL 3 / PL e.
- Safety-related shutdown of output modules within the potential group of the F-PM-E
- Two fail-safe digital inputs, for reading of sensor information (1 or 2 channels)
- One fail-safe digital output onboard (ppm switching, up to 2 A, up to SIL 3/PL e)
F-CM AS-i Safety
The F‑CM AS‑i Safety ST fail-safe communication module supplements an AS-Interface network without additional wiring to produce a safety-related AS-i network.
- 31 safe 2-channel AS-i inputs with integrated discrepancy evaluation
- Optional control of 16 safe AS-i outputs
