Innovation for AS-i in stock: The Modular AS-i Master for ET 200SP

Date for the Release for Delivery : 2013-04-30

 

 

Product description:

AS-Interface connects sensors and actuators to plant system controls via a simple two-wire line - the yellow AS-i cable. The required AS-i bus nodes are distributed almost anywhere in the system, just easy, flexible and efficient. You can now use the AS-i Master in the same easy, flexible and efficient way: 
With the CM AS-i Master ST, Siemens offers a communication module for the scalable distributed I/O system ET 200SP that is to be used in an extremely versatile manner.

Now, via a single module, an existing ET 200SP station can be extended with up to 496 inputs and 496 outputs on the AS-Interface bus.  

 

 

Using a PROFINET interface module (IM) of the ET 200SP, it is easy to set up a PROFINET/AS-i Link. As several CM AS-i Masters can be plugged into the ET 200SP, expanding such a link to a double or multiple master is no problem - up to 8 AS-i Masters can be operated behind one IM 155-6PN ST. Such an AS-i link can be additionally assigned local inputs and outputs directly in the ET 200SP rack thanks to the use of further I/O modules from the wide delivery spectrum of the ET 200SP.  With the PROFIBUS interface module, PROFIBUS/AS-i Link can also be set up in a completely flexible range of configurations.

These modular AS-i Links are configured and programmed in the TIA portal (V12 or higher), with every single AS-i Slave being displayed and diagnosed on the screen, or in STEP 7 (classic) V5.5 SP3 or higher.

In combination with an ET 200SP CPU 1510SP / 1512SP / 1515SP PC (as of firmware V1.8 or higher), the preprocessing of AS-i signals is possible directly in the ET 200SP station as well as the configuration of a stand-alone AS-i station without a higher-level CPU.

Safety-related applications can be realized by a combination with the module F-CM AS-i Safety ST, see 90880044

An overview about the possible combinations of the modules CM AS-i Master ST and F-CM AS-i Safety ST together with the ET 200SP Interface Modules and ET 200SP CPU Controllers, see   103624653

 

 

Performance characteristics CM AS-i Master ST:

  • Up to 62 AS-Interface slaves can be connected

  • Supports all AS-Interface master functions according to the AS-Interface specification V3.0

  • User-friendly configuration in TIA Portal (with graphical display of the AS-i line), in STEP 7 classic 
    or via GSD in other systems

  • Supplied by the AS-Interface cable

  • Suitable for AS-i Power24V and for AS-Interface with 30 V voltage

  • Integrated ground-fault monitoring for the AS-Interface cable

  • Thanks to connection to AS-Interface, the available number of digital inputs and outputs for the controller is drastically increased in combination with the ET 200SP (max. 496 DI/496 DQ on the AS-Interface for each CM)

  • Integrated analog value processing (all analog profiles)

Additional functions as of firmware V1.1 (or higher):

● Option handling at the level of the AS-i slaves
● Bus configuration can be expanded and modified during operation (proxy slaves)
● Comprehensive configuring of the AS-i slaves in STEP 7 possible
● Length of process image can be expanded up to 288 bytes (with PROFINET IM155-6PN HF)or up to 256 bytes (with PROFINET IM155-6PN ST).Length of process image up to 32 bytes with PROFIBUS IM155-6DP HF.
● Length of process image can be reduced to less than 32 bytes
● Analog data transfer in the cyclic process image
● Free positioning of the slave input/output data in the process image
● Basic diagnostics in the cyclic process image (status bits)
● Detailed diagnostics via data set
● Simplified reading of the error counters
● ID1 code assignment with automatical adaption from the configuration possible
● ID1 code assignment to any address manually possible
● Detection of multiple addresses optimized
