    • A fail-safe safety switching device comprises first and second input channels for receiving first and second input signals, and a first testing arrangement for testing the first and second input channels. The first input channel comprises a first entry circuit and a first threshold element connected via a first coupling element to a second testing arrangement and a first transition circuit in a galvanically isolated manner. The second input channel comprises a second entry circuit and a second threshold element connected via a second coupling element to a third testing arrangement and a second transition circuit in a galvanically isolated manner. The first testing arrangement comprises a third coupling element, a ground terminal and a group testing terminal. The first and second threshold elements are connected to the ground terminal and via the third coupling element to the group testing terminal in a galvanically isolated manner.

    • While a microcomputer 100A is executing a self-diagnosis (A), second diagnosis pulse output means 110B of a B-system microcomputer 100B is not used utterly. Further, during this time, the B-system microcomputer 100B does not execute a processing relating to at least the self-diagnosis (A) utterly. By shifting the timings for the A-system and the B-system to output the diagnosis pulses, independencies can be secured between respective diagnosis processing (self-diagnoses (A) and (B)). Thus, the independencies between the A-system and the B-system can be verified briefly by the self-diagnosis (A) on the A-system side. Further, first diagnosis pulse group are outputted parallel and simultaneously from first diagnosis pulse output means 110A. Thus, since cyclic control is not required for respective external input devices, it can be done to verify the independencies between the A-system and the B-system within a short period of time.
    • 在微型计算机100A执行自诊断(A)的情况下,不完全使用B系统微计算机100B的第二诊断脉冲输出单元110B。 此外,在此期间,B系统微计算机100B完全不执行与至少自诊断(A)有关的处理。 通过移动A系统和B系统的定时输出诊断脉冲,可以在各自的诊断处理(自诊断(A)和(B))之间确保独立性。 因此,A系统和B系统之间的独立性可以通过A系统侧的自我诊断(A)进行简单的验证。 此外,第一诊断脉冲组从第一诊断脉冲输出装置110A并行输出。因此,由于对于各个外部输入装置不需要循环控制,因此可以进行A系统和B系统之间的独立性的验证 系统在短时间内。

    • A self diagnostic system is integrated into an application program for controlling a machine or process. The application program is comprised of various logical segments that have to be solved by a logic solving engine. The diagnostic program will annunciate an event when the application program cannot execute a desired response by monitoring certain preselected and marked segments of the application program and allocating memory to save the result. When an abnormal occurrence in these segments results in the desired event not occurring, the diagnostic system will determine what part of the logic expression controlling the event could not be completed. This information will be saved and used for annunciating the reason for the desired event not happening. The diagnostic system includes a special control module that is added to the application program. This module is implemented as either an instruction added to the marked logic segment that is to be monitored in the case of a ladder logic system or as a subroutine as part of other types of sequential control methods. The data is recorded automatically, without application programming.
    • 自诊断系统被集成到用于控制机器或过程的应用程序中。 应用程序由必须由逻辑解算引擎解决的各种逻辑段组成。 当应用程序通过监视应用程序的某些预选和标记段并分配存储器来保存结果时,诊断程序将通知应用程序无法执行所需的响应。 当这些段中的异常发生导致所期望的事件不发生时,诊断系统将确定控制事件的逻辑表达式的哪一部分无法完成。 此信息将被保存并用于通知未发生所需事件的原因。 诊断系统包括添加到应用程序中的特殊控制模块。 该模块被实现为在梯形逻辑系统的情况下添加到要被监视的标记逻辑段的指令或作为其他类型的顺序控制方法的一部分的子例程。 数据自动记录,无应用程序编程。
