1.4 Definition of terms
Output switching element (safety output) of the AS-Interface safety monitor
Element activated by the logic of the monitor which is able to safely switch off the downstream
control elements. The output switching element may switch to or remain in the ON state only
when all components are functioning as intended.
Output circuit
Consists of the two logically connected output switching elements.
OSSD
The safe AS-Interface components and functional devices assigned to an output circuit of the
AS-Interface safety monitor. They are responsible for releasing the machine element which ge-
nerates the hazardous movement.
Integrated slave
Component with which sensor and/or actuator functions are grouped together with the slave
into a unit.
Configuration operation
Operating state of the safety monitor in which the configuration is loaded and checked.
Master
Component for data transmission which controls the logical and temporal behaviour on the
AS-Interface line.
Protective operation
Operating state of the safety monitor in which the sensors are monitored and the output swit-
ching elements are switched.
Safety output
See output switching element.
Safe output slave
Slave to which the safe ON or OFF state is transferred by the safety monitor and which controls
a safe actuator for switching off or shutting down while under voltage.
Safe input slave
Slave which reads in the safe ON or OFF state of the connected sensor or command device
and transmits it to the master or safety monitor.
Safe slave
Slave for connecting safe sensors, actuators and other devices.
Safety monitor
Component which monitors the safe slaves and the correct function of the network.
