Abstract

The invention relates to a system and a method for the failsafe transmission of data, the system having at least one component (2, 6, 7), which is enhanced for the failsafe transmission of data. To allow the failsafe transmission of data with reduced hardware outlay, it is proposed according to the invention that the one-channel component (2, 6, 7) is enhanced for the fail-safe transmission of data in that it is connected via a bus (1) to a failsafe computer unit (8), it has a communication driver (23), which maintains the data in standard and non-standard form, the communication driver (23) maintains a marker value, which indicates whether safe replacement values or real values are used, in standard and non-standard form.
