2.6.3 Advanced Logic Functions – ALF
Use
Use ALF to create more complex operations of logical input signals LIN_x or if, for reasons
of clarity in the application, it makes sense to create a specific combination of LIN_x as an
internal safe logic signal
The Advanced Logic Function can be used to link internal inputs and outputs logically. This allows spe­
cial input combinations to be implemented, for example. ALF is used when more complex logical links
are required and the input logic (OR gates with 4 upstream AND gates, each with 7 inputs) of a safety
function is insufficient.
