  • Parameterization conforms with other fail-safe I/O modules of the ET 200SP
• The communication module supports PROFIsafe in PROFINET and PROFIBUS configurations. It can be used with fail-safe SIMATIC S7‑300F/S7‑416F CPUs and S7‑1500F CPUs and also the fail‑safe versions of the ET 200SP station with ET 200SP F‑CPU 1510SP F / 1512SP F (firmware V1.8 or higher) or 1515SP PC F
• For reading up to 31 fail-safe AS-i input slaves
  • Two sensor inputs/signals for each fail-safe AS‑i input slave
  • Adjustable evaluation of sensor signals: 2-channel or 2 x 1-channel
  • Integrated discrepancy evaluation in the case of 2-channel signals
  • Integrated AND operation in the case of 2 x 1-channel signals
  • Input delay can be parameterized
  • Start-up test can be set
  • Sequence monitoring can be activated
• For control of up to 16 fail-safe AS-i output circuit groups
  • The output circuit groups are controlled independently of one another
  • One output circuit group can act on one or more actuators (e.g. to switch drives simultaneously)
  • An actuator (e.g. a contactor) is interfaced via an AS‑i safety output module (e.g. SlimLine S45F safety module, Article No. 3RK1405‑1SE15‑0AA2; see "ASIsafe" в†’ "Fail-safe AS‑Interface modules").
  • Simple fault acknowledgment via the process image
• Simple module replacement thanks to automatic importing of the safety parameters from the coding element
• Comprehensive diagnostic options
• Can be plugged onto type C1 or type C0 BaseUnits (BU)
• Informative automatic alarm indications (firmware V1.0.1 or higher)
• Supply via AS-Interface voltage
• Eight LED indicators for diagnostics, operating state, fault indication and supply voltage
• Informative front-side module inscription
  • Plain text marking of the module type and function class
  • 2D matrix code (Article No. and serial number)
  • Connection diagram
  • Color coding of the CM module type: light gray
  • Hardware and firmware version
  • Complete Article No.
• Optional labeling accessories
  • Labeling strips
  • Reference identification label

Design

The fail-safe F‑CM AS‑i Safety ST module has an ET 200SP module enclosure with a width of 20 mm.

One AS-i master according to the AS-i Specification V3.0, as well as fail-safe AS-i input slaves and/or AS-i safety output modules are needed for operation. The CM AS‑i Master ST communication module (article no. 3RK7137‑6SA00‑0BC1) is recommended as the AS‑i master for the ET 200SP, see "CM AS‑i Master ST for SIMATIC ET 200SP".

Simple combination of the CM AS‑i Master ST and F‑CM AS‑i Safety ST modules in one ET 200SP station results in a powerful, safety-oriented router between PROFINET (or PROFIBUS) and AS‑Interface, which can be expanded further in a modular fashion.

Combination of an ET 200SP interface module, CM AS‑i Master ST and F‑CM AS‑i Safety ST

With the digital and analog I/O modules of the ET 200SP, additional local inputs and outputs can be realized so as to ensure that the modular AS‑i router complies precisely with customer requirements. Expansion variants for almost every application are possible thanks to the selection of standard and fail-safe I/O modules.

Besides the single AS-i master, double, triple or generally multiple masters can be realized with or without fail-safe functionality.

Supported BaseUnits

With the combination of the CM AS‑i Master ST and F‑CM AS‑i Safety ST modules, the CM module is plugged onto a light type C0 BaseUnit and, directly to the right of it, the F‑CM module is plugged onto a dark type C1 BaseUnit. The AS-i cable is connected only on the light BaseUnit of the CM module.

Notes on safety

In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens products and solutions only represent one component of such a concept.

Configuration

The following software is required for configuration of the F‑CM AS‑i Safety ST module:

• STEP 7 (classic), V5.5 SP3 HF4 or higher with HSP 2093¹⁾ and Distributed Safety V5.4 SP5 or F-Configuration Pack SP11

or

• STEP 7 (TIA Portal) V13 and higher with HSP 0070 ²⁾ and Safety Advanced V13.
  For connection to S7‑1500F you require STEP 7 V13 SP1. When configuring with STEP 7 V13 SP1, the latest version of HSP 0070 V2.0 (or higher) is an essential prerequisite. STEP 7 Safety V13 SP1 Update 4 and the new version of HSP 0070 V3.0 (or higher) is needed for configuration of the F‑CM AS‑i Safety ST module in an ET 200SP station with ET 200SP F‑CPU 1510SP F / 1512SP F (firmware V1.8 or higher) or 1515SP PC F.

Configuration and programming are done entirely in the STEP 7 user interface. No additional configuration software is needed for commissioning.

Data management – together with all other configuration data of the SIMATIC – is realized completely in the S7 project.

The input and output channels are assigned to the process image automatically and manual linking via configuration function blocks is not necessary.

If the F‑CM AS‑i Safety ST module is replaced, all necessary settings are automatically imported into the new module.

The F‑CM AS‑i Safety ST module occupies 16 input bytes and 8 output bytes in the I/O data of the ET 200SP station.

For diagnostics during ongoing operation, diagnostics blocks with clearly arranged visualization on the SIMATIC HMI panel are available or can be downloaded free of charge via a web browser,see https://support.industry.siemens.com/cs/ww/en/view/109479103.
