ifm AS-i gateways with fail-safe PLC
Applicable products:Monitors, PLCs and gateways
AS-i safety monitors are used to monitor protective equipment such as E-stops in AS-i systems.
They monitor the code sequences to be transmitted in the AS-i network. In the case of message deviations or timeouts the monitor ensures the safe state of the system.
The unit is available in two versions: with either one or two redundantly designed output switching elements. It can be connected to the AS-i system at any position. Several AS-i safety monitors can be operated via one AS-i master. Any grouping for evaluation of the safe AS-i slaves is possible.
Known safety relay functions like "E-stop", "stop categories 0 or 1", "two-hand operation" or "enable switch" can be implemented via the software. One AS-i safety monitor thus replaces many traditional safety relays.
ifm Safe input/output modules
Safe input/output modules
Safe AS-i modules detect safety-related switching states of 1- or 2-channel E-stops, position switches or door contacts. Using the safe input module safety-related components without integrated AS-i interface can be connected to the AS-i system.
The units comply with the applicable international standard requirements for safety technology. They detect and signal short circuits, cross faults and communication errors. The switching states of the inputs and outputs, the voltage supply and potential faults are indicated by powerful LEDs on the module.
The product range includes ClassicLine modules with screw or quick mounting technology for field use and SmartLine modules for control cabinet installation.
ifm Operating elements
Operating elements
The safe mushroom-headed E-stop buttons with AS-Interface force a machine or installation to stop or shut down in a hazardous situation. The integrated AS-i connection allows integration of the E-stop devices into safe AS-i systems (Safety at Work). Depending on the type, a pull or key is required to release a previously triggered E-stop.
ifm Safe AS-i door switches
Safe AS-i door switches
AS-i door switches with guard locking have the function to keep moving protective equipment such as protective grating, protective guards and other covers closed as long as a dangerous state is present. They are used in safe AS-i systems (Safety at Work) and operate as electromagnetic interlocks with guard locking.
In combination with a guard and the machine control system this safety component prevents the safety guard from being opened while there is potential of exposure to a mechanical hazard. For the control system this means that switch-on commands which cause hazardous situations must become active only when the safety guard is in a protective position and the guard locking in locked position. The locked position of the guard locking must be released only when the hazardous situation is no longer present.

Safety rope emergency stop switches
Safety rope emergency stop switches are often used in conveyor belt systems to secure large danger areas. Pulling the tensioned rope, rope breakage or impact on the E-stop cause activation of the switching function of the safety rope emergency stop switch. After activation of the E-stop function a clip mechanism maintains the E-stop command until it is unlocked manually by pressing the blue reset button.
Reset is only possible with correct rope tension.
The rope tension is adjusted directly on the safety rope e-stop switch. The switch features a rope tension indicator to facilitate adjustment, troubleshooting and maintenance.
Using AS-i PCBs, rope switches, belt drift switches and other switches can be integrated into AS-i systems. If needed, this can also be safety-related (Safety at Work).

AS-Interface Safety at Work – PCB solutions
AS-i PCBs can be installed in small housings, control cabinets and panels. Some of the PCBs are fully potted and can be integrated into surface mounting enclosures, e.g. for installation of illuminated pushbutton modules.
With the help of AS-i PCBs mechanical switches can be integrated into AS-i networks. They combine the functionality of the switches with the easy installation of AS-i.
AS-Interface Safety at Work
AS-Interface is a simple and economic wiring system for the first level of industrial communication. An AS-Interface network consists of a control unit, the so-called master, the modules for signal processing, and the associated sensors and actuators.
Safety components can easily be incorporated into an AS-i network via AS-Interface Safety at Work. Signals from standard units and safe components are transmitted via a common cable.
The fail-safe AS-i PLC is certified for use in safety-related applications up to SIL3, PL e.
AS-i safety monitors are used to monitor safety components in AS-i systems. They monitor the code sequences to be transmitted in the AS-i network. In the case of message deviations or timeouts the monitor ensures the safe state of the system.
Safe AS-i modules detect safety-related switching states of 1- or 2-channel E-stops, position switches or door contacts. Using the safe input module safety-related components without integrated AS-i interface can be connected to the AS-i system.
