Note
The relationship betw
een the logic level and the external voltage level at the input depends on the parameterization (see
p10040) of the input as NC contact or NO contact, and is aligned to the use of a safety function:
With 24 V at the input, NC contacts have a logical "1" level, for 0 V at the input, a logical "0" level.
This means that an NC/NC contact parameterization of 0 V at both inputs of the F-DI leads to a status of the F-DI equal
to "0" (safety function selected), for 24 V at both inputs of the F-DI, to a status of the F-DI equal to "1" (safety function
deselected).
With 24 V at the input, NO contacts have a logical "0" level, for 0 V at the input, a logical "1" level. This means that for
an NC/NO contact parameterization, the level 0 V/24 V leads to a status of the F-DI equal to "0" (safety function selected),
the level 24 V/0 V leads to status of the F-DI equal to "1" (safety function deselected).
