Muting With AS-Interface – Cost-Effective, Easy, Flexible

Using AS-Interface as a bus system, it is possible to implement muting applications up to SIL3/PLe easily and efficiently. Thanks to ASi-5 Safety, you can now realize cross-muting and sequential muting far more cost-effectively than with comparable Ethernet-based solutions. Our new, compact ASi-5 Safety Muting Module processes all signals required for muting. Ready-certified muting modules can be configured quickly and easily.


We also offer a solution for widely dispersed sensors: our active distributors capture the signals where they occur. All of Bihl+Wiedemann's muting solutions allow you to benefit from the proven advantages of ASi: Free choice of topology, extremely easy installation thanks to piercing technology as well as drastically reduced cable use. Find out here why AS-Interface is a resource-saving technology.

Muting Nedir?

Muting, elektronik hassas koruyucu ekipmanın geçici olarak devre dışı bırakılmasını (şöntleme) ifade eder. Bu bir fotosel veya bir ışık perdesi olabilir. izin verilen malzeme akışı ile izin verilmeyen nesneler veya kişiler arasındaki ayrım, uygun şekilde monte edilmiş muting sensörleri tarafından yapılır. Muting sensörleri dizilirken çapraz (Resim 1) ve sıralı ( Resim 2) muting arasında bir ayrım yapılır. Bir Bus sistemi olarak ASi, çeşitli muting düzenlemelerinin uygulamasını kolay, verimli ve düşük maliyetli bir şekilde uygulama imkanı sunar.

The arrangement of the two sensors with cross muting is crossed. They must both be activated simultaneously to initiate the muting cycle.

With a sequential arrangement, multiple sensors are connected one after the other; they must be activated or deactivated consecutively in a certain sequence.

Advantages of the ASi-5 Safety Muting Module

Cost Savings

Benefit from significant cost advantages in comparison to comparable Ethernet-based muting solutions from other providers. Apart from the significantly lower module costs, AS-Interface can also save up to 70% in wiring costs compared to round cable solutions.


All signals in one module. The modules can be connected flexibly, whether for cross-muting or sequential muting. Unused inputs and outputs can be used for other applications. Alternatively to processing the relevant signals in the Safety Monitor, they can also be forwarded via PROFIsafe, CIP Safety, FSoE, or openSAFETY.


Using our Bihl+Wiedemann Software Suite, ready-certified muting devices can be configured quickly and easily for many applications. This way, it is possible to make further setting options, such as "End muting when the light barrier is released," "Tolerated interruption time," "Belt stop" and timing parameters. No complex programming in the control system is required.

Proven ASi

AS-Interface allows you to benefit from freely selectable topology. Thanks to piercing technology, the installation process is extremely simple and fast. This not only saves on material and assembly costs, but also minimizes errors during installation.

One Module for All Signals

  • Cost-efficient solution for cross-muting and sequential muting with many inputs and outputs
  • All signals required for muting in just one module using one ASi-5 address
  • Convenient parameterization via the PC software with a certified muting building block
  • For example, unassigned inputs and outputs can be used to control muting lamps and motors or to integrate push button modules
  • All relevant signals can be preprocessed in the Safety Monitor or optionally forwarded via PROFIsafe, CIP Safety, FSoE or openSAFETY

Aktif Dağıtıcılar ile Muting

Muting söz konusu olduğunda önemli olan bireysel taleplerin önceden dikkate alınmasıdır. Tüm sinyalleri tek bir yere bağlamak her zaman en mantıklısı değildir, örn.: sensörler birbirlerinden çok uzak olduğunda. Bihl+Wiedemann bu tür uygulamalar için de uygun çözümler sunmaktadır - örn.: aktif dağıtıcıları kullanarak. Sinyaller bulundukları yerlerden toplanmaktadır.
