Safety Interface offers multi-functional monitor.

Press Release Summary:



AS-interface system, Safety at Work, offers safety monitor that includes logic functions and expansions for applications, such as control of door-locking systems and modules, such as fail-safe flip-flop. Selectable logic modules for Emergency Stop control and multiple Stop applications are also available. System does not require fail-safe controller and can be expanded by addition of new stations. It consists of central monitor, fail-safe input modules, and integrated fail-safe sensors.

AS-Interface: Safety Monitor with New Functions


The safety monitor for the AS-interface system "Safety at Work" has been up-graded to include new logic functions. Included are expansions for applications such as control of door locking systems and modules such as a fail-safe flip-flop. These expansions greatly enhance the user-friendliness of safety systems while helping to rationalize plant development. The monitor currently provides select-able logic modules for such applications as Emergency Stop control and multiple Stop categories.

The AS-interface consortium Safety at Work consists of the following companies and represents the leading providers of safety technology for the manufacturing automation sector: Euchner, Festo, IDEC, IFM, Leuze, Moeller, Omron, Pepperl+Fuchs, Sick, Schmersal, Schneider and Siemens. Honeywell and EJA joined in 2002.

The development association is dedicated to the fail-safe expansion of the AS-interface fieldbus system and marketed its first products in 2001. Several hundred AS-interface installations are now in use worldwide. Products developed within the consortium can be marketed under each member's own label.

The applications include everything from safety technology for final assembly lines in production plants to luggage conveyor systems at airports. AS-interface Safety at Work simplifies the wiring in fail-safe applications, as both safety signals and standard signals can be transmitted over the IEC 62026 standard AS-interface fieldbus. Moreover, the system does not require a fail-safe controller, and can be expanded simply by adding new stations.

The AS-Interface Safety at Work system consists essentially of the central monitor, fail-safe input modules and integrated fail-safe sensors. Sensors without an integrated AS-interface connection, such as Emergency Stop pushbuttons, door locking systems, light curtains, safety mats or other sensors of a similar nature, can be connected by means of fail-safe input modules.

Norbert Ehninger, head of conveyor system planning at DaimlerChrysler in Bremen, Germany, had this to say: "With AS-Interface Safety at Work we now have a cost-effective, flexible safety system for all aspects of final assembly. Indeed, AS-interface Safety at Work has allowed us to build one of our company's most successful production plants with optimum plant availability."

In the next upgrade, the safety monitor, which also contains the fail-safe outputs, will be expanded to include even more logic functions. The monitor currently provides selectable logic modules, e.g. for controlling Emergency Stop applications or other Stop categories. The expansions are intended for applications such as controlling a door locking system or modules such as a fail-safe flip flop.

Safety at Work is already in use in hundreds of installations. These include final assembly in automotive plants, conveyor systems, compact machines, even the luggage transport systems used at airports. The applications focus on installations in which it is necessary to transmit and process both standard and fail-safe information.
