    • A process is provided for generating a flow chart representing a control program defined by associative relationships between program levels, states and conditions, each condition specifying a transition from an associated one of the states as a source state to a corresponding selected destination state upon satisfaction of the condition during execution of the control program by the logic control unit. Each program level defines a sub-process of the control program. The process includes the steps of rendering on a chart: a first group of state indicators each representing a corresponding one of a first plurality of the states, and including an associated first state anchor point; a first group of condition indicators each being associated with a corresponding one of the first group of state indicators, each of the first group of condition indicators indicating a corresponding one of a first plurality of the conditions, and including an associated first condition anchor point; a second group of state indicators each indicating a corresponding one of a second plurality of the states, and including an associated second state anchor point; a second group of condition indicators each being associated with a corresponding one of the second group of state indicators, each of the second group of condition indicators indicating a corresponding one of a second plurality of the conditions, and including an associated second condition anchor point; and for each of the conditions, a corresponding transition indicator indicative of transition information specified by the condition.
    • 提供了一种处理,用于生成表示由程序级别,状态和条件之间的关联关系定义的控制程序的流程图,每个条件指定从满足以下条件的状态之间的相关联的状态到相应的所选目的地状态 由逻辑控制单元执行控制程序期间的状态。 每个程序级别定义控制程序的子进程。 该过程包括以下步骤:在图表上渲染:第一组状态指示符,每个状态指示符表示第一多个状态中相应的一个状态,并且包括相关联的第一状态锚点; 第一组条件指示符,每个条件指示符与第一组状态指示符相对应,第一组条件指示符中的每一个指示第一多个条件中的相应一个,并且包括相关联的第一条件锚点; 第二组状态指示符,每个指示第二多个状态中的相应一个,并且包括相关联的第二状态锚点; 每个条件指示符与第二组状态指示符相对应的第二组条件指示符,第二组条件指示符中的每一个指示第二多个条件中的相应一个,并且包括相关联的第二条件锚点; 并且对于每个条件,指示由条件指定的转换信息的相应转换指示符。
