Significance
Output with a specific clock signal that is directed by a sensor and that is
detected by a related input. This clock signal distinguishes itself from other
cycles similar to functions and enables the diagnosis of cross-circuiting on
switched signals.
In the operating mode "Passivation by channel", depassivation involves
setting the Acknowledge bit in the output data è Chapter 1.3.2.
In the operating mode "Passivation by module", depassivation involves
è Reintegration.
è Input channel
Collective designation for safety-related devices è Safety control unit.
Safety control unit for control of safety-related devices.
Functional testing procedure to determine the switching capability of sig­
nals. With outputs, this procedure is often used in the form of test pulses,
and for clocked inputs. Generally speaking, many safety-related signals can
be found to have forced dynamic responses in order to detect short circuits
and cross-circuiting.
Safety-related system that moves to a safe status when dangerous system
and device errors occur.
