    摘要： The invention relates to method for monitoring and determining preceding states of at least one terminal of an automation system. The automation system comprises at least one terminal (1, 2), which can assume at least two state values and which outputs a monitoring message that depends on the at least two state values, and comprises a control unit (3) that reads in the monitoring message from the at least one terminal (1, 2). The at least one terminal (1, 2) outputs another monitoring message only after it has received an acknowledgement signal (Q) from the control unit (3). In order to be able, even subsequently, to reconstruct at least some of the preceding state changes, the monitoring message contains, in addition to each state value, at least one additional component (S1_Z, S2_Z; S1_OV, S2_OV) whose state is changed during a transition of the state value and is reset to an initial state when a monitoring telegram is output.

    摘要翻译： 本发明涉及用于监视和确定自动化系统的至少一个终端的先前状态的方法。 自动化系统包括至少一个终端（1,2），其可以采取至少两个状态值并且输出取决于至少两个状态值的监控消息，并且包括控制单元（3），该控制单元读入 监视来自所述至少一个终端（1,2）的消息。 至少一个终端（1,2）仅在其已经从控制单元（3）接收到确认信号（Q）之后才输出另一个监控消息。 为了甚至随后能够重建至少一些之前的状态改变，除了每个状态值，监视消息还包含其状态被改变的至少一个附加分量（S1_Z，S2_Z; S1_OV，S2_OV） 在状态值的转换期间，并且当输出监视报文时被复位到初始状态。
