    摘要: A one-channel transmission of information on a bus system within an automation system is provided. Data transmission, in compliance with safety integrity level 2 according to IEC 618508, is achieved with reduced hardware outlay. The information to be transmitted via the bus system contains net data, which is present within a processing unit in two channels in the form of a first data set and in the form of a second data set that differs from the first data set at least in the form of representation. The processing unit generates a transmission telegram suitable for one-channel transmission on the bus system from the two data sets, whereby the net data present in the form of the first data set is stored in a first data area of the transmission telegram and a checksum generated on the basis of the second data set is stored in a second data area of the transmission telegram.

    摘要: 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.
