Overview
F-CM AS-i Safety ST for SIMATIC ET 200SP
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.
Important features:
•
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 configurations. Suitable for use with fail-safe
SIMATIC S7-300F/S7-416F CPUs.
•
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 a fail-safe
AS-i output module (e.g. safe SlimLine module S45F,
Article No. 3RK1405-1SE15-0AA2, see page 4/10).
- 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 indica-
tion and supply voltage
•
Informative front-side module inscription
- Plain-text marking of the module type and function class
- 2D matrix code (article number and serial number)
- Circuit diagram
- Color coding of the CM module type: Light gray
- Hardware and firmware version
- Complete article number
•
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 and
fail-safe AS-i input slaves and/or fail-safe AS-i output modules
are needed for operation. The CM AS-i Master ST communica-
tion module (Article No. 3RK7137-6SA00-0BC1) is recom-
mended as the AS-i master for the ET 200SP, see page 4/38.
SIMATIC AS-i F-Link
Simple combination of the CM AS-i Master ST and F-CM
AS-i Safety ST modules in one ET 200SP station with PROFINET
interfacing results in a powerful PN/AS-i F-Link, which can be
expanded further in a modular fashion.
SIMATIC AS-i F-Link: 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, local
inputs and outputs can be realized in the SIMATIC AS-i F-Link so
as to ensure that the F-Link 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 multi-
ple masters can be realized with or without fail-safe functionality.
