Safety monitor won't miss the bus
The SFM-B02 safety monitor allows systems designers to link AS-Interface Safety at Work systems with existing higher-level buses such as Profibus, DeviceNet or Ethernet.
With the use of AS-Interface Safety at Work systems it is possible to connect this safe bus to an existing higher-level bus such as Profibus, DeviceNet or Ethernet And there are now more ways of simplifying safety systems

Enabling switches are used wherever personnel are required to work directly on running machines and systems, with the obvious associated hazards and dangers.

A Euchner EKS system has been integrated into each of six process terminals for soap production at the Hirtler company.
For instance, the existing SFM-A01 and SFM-A02 safety monitors from Euchner (UK) are now joined by the new and powerful SFM-B02.
Among the advantages of this growing technology are that conventionally (parallel) wired safety systems are replaced with bus-compatible safety systems on the AS-Interface bus and all diagnostic lines directly connected to the controller are eliminated.
This represents considerable cost savings.
The changes required to the controller in order to integrate AS-Interface Safety at Work are minimal.
A simple "gateway" in the diagnostic software acts an interface so that the AS-Interface can operate as a subsystem of the fieldbus already in use.
This means that information from the AS-Interface bus appears as a data record on the higher-level bus and thus does not become directly "visible" as all evaluation work takes place in the normal manner within the fieldbus.
Alternatively it is possible to integrate an AS-Interface master into the controller.
Whichever option is selected, very little specialist knowledge is required, as the safe modules only need an address in order to become operational.
With expanded features the new SFM-B02 monitor offers additional logic functions.
Also available is a special safety switch module with guard locking device similar to that incorporated in the Euchner TP and TZ series.
After a brief period using AS-Interface Safety at Work, the advantages soon become apparent and this innovative technology is becoming more and more widespread in projects throughout industry.
Other than cost, another advantage is that the equipment on the existing bus can be retained for further use, while simultaneously using an absolute power bus system for wiring the safety systems.
With its SFM-B02 monitor, Euchner reckons it has taken the next step in developing the potential of the AS-Interface Safety at Work bus.
