Failsafe transmission of data
First Claim
1. A system for the failsafe transmission of data, comprising:
- at least one one-channel component, the component comprising;
an interface for connecting the component via a bus to a failsafe computer unit;
a communication driver maintaining the data in standard and non-standard form, wherein the communication driver maintains a marker value indicating whether safe replacement values or real values are used, wherein the marker value is in standard and non-standard form, and wherein a checksum is generated in the communication driver from the data maintained in non-standard form; and
a program run control for monitoring a program flow; and
wherein the one-channel component is provided with a disabled failsafe data supplement and an active failsafe one-channel communication driver for at least intermittent use in applications that are without relevance to safety for the failsafe data supplement, and wherein the failsafe data supplement is released during intermittent disabled failsafe data supplement use in applications with relevance to safety.

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.
