Siemens F-CMAS-I Safety ST

Manufacturer: Siemens

The FCM ASi Safety ST fail-safe communication module supplements an AS-Interface network without additional wiring to produce a safety-related AS-i network.

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 and 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 PROFIBUS or PROFINET/AS‑i F‑Link, which can be expanded further in a modular fashion.

Features Applications Model

Fail-safe communication module for the ET 200SP
31 fail-safe input channels in the process image
16 fail-safe output channels in the process image
Certified up to SIL 3 (IEC 62061/IEC 61508), PL e (EN ISO 13849‑1)
Parameterization conforms with other fail-safe I/O modules of the ET 200SP
The communication module supports PROFIsafe in PROFINET and PROFIBUS configurations. Can be used with fail-safe SIMATIC S7‑300F/S7‑416F CPUs and S7‑1500F CPUs (TIA Portal V13 SP1 and higher with HSP 0070 V2.0).
For reading up to 31 fail-safe AS-i input slaves
2 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" → "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)
Supply via AS-Interface voltage
8 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

Thanks to use of the fail-safe module in the ET 200SP, it is possible to fulfill the safety-related application requirements in a manner that is integrated in the overall automation solution.
The safety functions required for fail-safe operation are integrated in the modules. Communication with the fail-safe SIMATIC S7 CPUs is realized via PROFIsafe.
The safety application is programmed in the SIMATIC S7 F‑CPU with Distributed Safety. The fail-safe input signals of the ASIsafe slave modules are read via the AS‑i bus line and are combined with any chosen further signals in the fail-safe program.
The fail-safe output signals can be output via safe SIMATIC output modules or also directly via AS‑i – with the aid of safe AS‑i output modules, e.g. SlimLine S45F safety modules, article number 3RK1405‑1SE15‑0AA2 (see “ASIsafe” → “AS‑Interface Safety Modules”). No special functions are required for this in the program.
Operation with SINUMERIK 840D sl is possible with software version V4.7 or higher.
Together with an ET 200SP F‑CPU 1510SP F/1512SP F (firmware V1.8 or higher), preprocessing of safe AS‑i signals directly in the ET 200SP station and setting up of an independent AS‑i Safety station without a higher-level CPU is possible.
