    • 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。

    • A controller (104) stores link information (185) linking a predetermined event to a variable associated with the event. The controller (104) stores first log information in association with time information into a memory (911) in response to occurrence of the predetermined event (905). The first log information includes information about the event, and a current value of a predetermined variable associated with the event included in the link information (185). The controller (104) stores second log information in association with time information into a memory (128) in accordance with a predetermined period. The second log information includes information about a value of the predetermined variable. An information processing device (300) obtains the link information (185) from the controller, and displays information indicating the variable associated with an event indicated by the first log information onto the monitor (314) based on the link information and the second log information.

    • The present invention provides a programmable controller for executing an SFC program. The programmable controller has a memory which stores a step trace program for storing and tracing a history of execution statuses of active steps of a plurality of blocks of an SFC during execution of the SFC program. The step trace program comprises a step trace setting subprogram which, through the use of a peripheral device, synchronously traces the execution statuses of the active steps of the plurality of blocks. The step trace program further comprises a step trace execution subprogram which creates step trace data based on the execution statuses of active steps traced by the step trace setting device. The programmable controller further comprises a step trace display device for displaying the step trace data. Hence, an operator can simultaneously view the execution status of active steps of a plurality of blocks of the SFC to thereby determine which active steps have been executed at any given time.
    • 本发明提供一种用于执行SFC程序的可编程控制器。 可编程控制器具有存储步骤跟踪程序,用于在执行SFC程序期间存储和跟踪SFC的多个块的活动步骤的执行状态的历史。 步进跟踪程序包括步进跟踪设置子程序,其通过使用外围设备同步地跟踪多个块的活动步骤的执行状态。 步进跟踪程序还包括步进跟踪执行子程序,其基于步进跟踪设置设备跟踪的活动步骤的执行状态创建步骤跟踪数据。 可编程控制器还包括用于显示步骤跟踪数据的步进跟踪显示装置。 因此,操作员可以同时查看SFC的多个块的活动步骤的执行状态,从而确定在任何给定时间已经执行了哪些活动步骤。
