Safe Link from Bihl+Wiedemann
Safe Link is a technology in the Gateways with integrated Safety Monitors and the Safety Basic Monitors with Ethernet interface. It allows safety controllers to be connected to each other simply, efficiently and with the greatest possible flexibility. Learn more about it in the following articles.
Other safe Ethernet systems
- Safe communication over the respective fieldbus via Ethernet
- Additional safety PLC (e.g. F-CPU) required
- Pure direct communication between safe PLC and each gateway
- Generally higher device costs
- Separate network
Both factory and process automation are showing a trend towards ever more complex, branched applications. The most efficient possible coupling of safe networks now becomes one of the special challenges in the area of safety.
A simple and cost effective solution
Bihl+Wiedemann has met this challenge with a simple and cost effective solution: Safe Link, i.e. safe coupling over the Ethernet interface of the ASi gateways with integrated safety monitor. In the maximum configuration this means up to 1922 safety two-channel input signals can be collected while controlling safety outputs either centrally or locally.
Couple up to 31 gateways
This approach enables up to 31 Safety Basic Monitors or Gateways with integrated Safety Monitor to be coupled to each other – without losing performance at any point and without the use of additional hardware.
Why safe coupling?
Many safe signals
- Up to 62 safe signals per safety monitor
- The more safe signals, the more safety monitors are needed
- Safety monitors are coupled to each other
Safe couple multiple machines
- Central E-Shop works on multiple machines
- E-Stop on one machine works for the neighboring machine
Widely distributed systems
- Encapsulating of system parts, segmenting
- Modular system construction
- Individual modules are coupled to each other
Safe coupling of machines
Safe information exchange is possible between different system parts and also diverse field bus protocols via diagnostic interface.
Learn how to seamlessly integrate safe sensors and actuators as well as safety monitors into all common automation systems with ASi Safety. Safe and unsafe signals can be transmitted on the same line.
PLC Independent Safety Technology
Discover the advantages of our safety and wiring technology, which is system and manufacturer-neutral. In this way, it enables simple, fast and thus cost-effective commissioning.
Discover how easy muting is with Bihl+Wiedemann's muting modules. All signals required for muting can be connected to a single module.
Selection of Mode of Safe Operation
Read all about how our TÜV-certified device facilitates "selection of mode of sfae operation selection": A standard HMI allows you to safely select up to 5 different operating modes for a maximum of 6 plant sections – each with unique safety functions.
