Structure of the PROFIsafe data

The meaning of the PROFIsafe process data is separately described for PROFIsafe output
data and PROFIsafe input data. All bits described are evaluated.

Unassigned bits are reserved for future functions and marked with "−". These bits must be
transmitted with "0".

PROFIsafe output data

The PROFIsafe output data is transmitted from the control to the safety module.
