Synchronization of Safety-Related Inputs
Overview
The device can monitor synchronized behavior of the input channels of the safety-related inputs
using various synchronization mechanisms with different synchronization times. If the
synchronized input channels of the safety-related inputs are not activated within the synchroni -
zation time, the safety-related output or outputs are not activated.
The synchronized terminals of the safety-related inputs and the corresponding synchronization
times are also listed for each individual application function ( see page 58 ) using synchronization,
including information on the sequences in which the synchronized input channels are activated, if
applicable.
Refer to the chapter Safety-Related Inputs
( see page 40 ) for additional information on the use of
the term “activation” in the present document.
