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, a checksum is generated in the communication driver ( 23 ) from the data maintained in non-standard form and a program run control is provided to monitor execution of the program.
