    • The present invention relates to an apparatus for controlling safety-critical processes. The apparatus includes at least one safe control unit for controlling the safety-critical processes and at least two safe signal units which are connected via I/O channels to the safety-critical processes. The safe control unit and the safe signal units are connected to a common fieldbus. The safe signal units communicate with the safe control unit, but not with one another, when the apparatus is in the control mode. The safe signal units have an evaluator for evaluating a fault message which is broadcasted across the fieldbus, as well as a switching device which autonomously change the safety-critical process to a safe state when a fault message which is evaluated as being relevant occurs.
    • 本发明涉及一种用于控制安全关键过程的装置。 该装置包括用于控制安全关键过程的至少一个安全控制单元和经由I / O通道连接到安全关键过程的至少两个安全信号单元。 安全控制单元和安全信号单元连接到公共现场总线。 当设备处于控制模式时,安全信号单元与安全控制单元通信,但彼此不通信。 安全信号单元具有用于评估跨现场总线广播的故障消息的评估器,以及当被评估为相关的故障消息发生时,将安全关键过程自主地改变为安全状态的交换设备。

    • The present invention relates to an electronic safety switching device having at least a first and a second signal processing channel. The channels can be supplied with input signals for signal processing, and they provide redundantly processed output signals. According to one aspect of the invention, the signal processing channels are arranged monolithically on a common semiconductor substrate. The semiconductor structures of each signal processing channel are spaced apart physically by a multiple of their width from the semiconductor structures of every other signal processing channel.
    • 本发明涉及至少具有第一和第二信号处理通道的电子安全开关装置。 通道可以提供输入信号进行信号处理,并提供冗余处理的输出信号。 根据本发明的一个方面,信号处理通道单片地布置在公共半导体衬底上。 每个信号处理通道的半导体结构在物理上与其它信号处理通道的半导体结构的宽度的倍数隔开。
