9.3.4 Transition

条件

The transition describes what must be fulfilled in this process step, so that the next step can be activated. The actions of the step are described in an assigned program. This program can be written in either the instruction list (IL), ladder diagram, function block diagram (FBD), or structured text (ST). The result of the transition (.RESULT) must be logic 1, so that the following step(s) can be activated.

条件描述了在此过程步骤中必须完成的内容，以便可以激活下一步。步骤的操作在分配的程序中描述。该程序可以用指令列表（IL），梯形图，功能块图（FBD）或结构化文本（ST）编写。条件的结果（.RESULT）必须是逻辑 1，以便可以激活以下步骤。

> Elements > Transition

菜单元素-条件

Insert a step-enabling condition. The name of the transition (max. 8 characters) must be stated definitely.

插入启用步骤的条件。必须明确说明转换的名称（最多 8 个字符）。

9.3.5 Vertical line

竖直线

Elements can be linked with a vertical line so that a step can be omitted, thus conferring more clarity on a string of the SFC structure.

元素可以用垂直线链接，以便省略步骤，从而使 SFC 结构的字符串更加清晰。

> Elements > Vertical line

菜单元素>竖直线

Insert a vertical line to make a line of steps and transitions complete.

插入垂直线以使步骤和条件完整。

A transition is always followed by a step irrespective of the branch, and vice-versa, a step is always followed by a transition.

无论分支如何，条件之后总是有一个步骤，反之亦然，一个步骤总是跟着一个条件。

9.3.6 Horizontal sequence selection line

水平顺序选择线

To omit a step and thus confer greater overall clarity on the SFC structure, it is possible to link the elements of a sequence selection with the horizontal sequence selection line.

为了省略步骤，从而使SFC结构的整体清晰度更高，可以将顺序选择的元素与水平顺序选择线链接起来。

> Elements > Horizontal seq. selection line

菜单元素>水平顺序选择线

Insert a horizontal sequence selection line to connect a column to the next but one column in a sequence divergence. Can only be inserted in the thin lines.

插入水平顺序选择线，将一列连接到顺序分歧中的下一列，但序列发散中的一列只能插入细线。

9.3.7 Sequence selection divergence start

顺序选择分支起点

In the case of a sequence selection, only one of several strings is computed. Each alternative string begins with a transition. These transitions decide whether or which string is alternatively computed. The start of a sequence selection is always placed after a step.

在顺序选择的情况下，仅计算多个字符串中的一个。每个替代字符串都以条件开头。这些条件决定是否或哪个字符串是替代计算的。顺序选择的开头始终放在步骤之后。

> Elements > Seq. selection divergence start

菜单元素 > 顺序选择分支起点

Open the sequence selection divergence of the preceding step. Can only be inserted in the thin lines.

打开上一步的序列选择分支。只能插入细线中。

Each started sequence selection divergence must be closed again.

必须再次关闭每个已开始的序列选择分歧。

9.3.8 Sequence selection divergence add

顺序选择分支增加

Apart from the start of a sequence selection, there is the element Sequence selection divergence add with which the number of alternative strings can be increased.

除了顺序选择的开始之外，还有元素顺序选择分歧添加，通过它可以增加替代字符串的数量

> Elements > Seq. selection divergence add

菜单元素>顺序选择分支增加

Open the sequence selection divergence add for the underlying transition. Can only be inserted in the thin lines.

打开基础条件的顺序选择分支增加。只能插入细线中。

9.3.9 Sequence selection convergence add

顺序选择收敛添加

Apart from the end of a sequence selection, there is the element Simultaneous sequence divergence start with which the alternative string is closed.

除了顺序选择的结尾之外，还有元素同时顺序发散开始，替代字符串从该元素开始闭合。

> Elements > Seq. selection convergence add

菜单元素> 顺序选择收敛添加

Close the sequence selection convergence of the previous transition. Can only be inserted in the thin lines.

关闭上一个过渡的顺序选择收敛。只能插入细线中。

9.3.10 Sequence selection convergence end

顺序选择收敛结尾

In the case of a sequence selection only one of several strings is computed. Each alternative string begins with a transition and ends with a transition. The last transition of the active string decides whether or when the sequence selection is closed. The end of a sequence selection is always placed before a step.

在序列选择的情况下，仅计算几个字符串中的一个。每个替代字符串都以条件开头，以条件结束。活动字符串的最后一个条件决定是否或何时关闭顺序选择。顺序选择的结尾始终放在步骤之前。

> Elements > Seq. selection convergence end

菜单元素>顺序选择收敛结尾

Close sequence selection convergence end of the previous transition and continue in the sequence control to the next step. Can only be inserted in the thin lines.

关闭顺序选择收敛结束前一个条件并继续在顺序控制中到下一步。

9.3.11 Horizontal simultaneous sequence line

水平同时选择线

To omit a string and thus confer greater overall clarity on the SFC structure, it is possible to connect the elements of a simultaneous sequence divergence with the sequence selection divergence start.

为了省略字符串，从而使SFC结构具有更大的整体清晰度，可以将同时顺序发散的元素与顺序选择发散开始连接起来。

> Elements > Horizontal simultaneous seq. line

菜单元素>水平同时选择线

Insert a simultaneous sequence line from a column to the next but one column in a sequence divergence. Can only be inserted in the thin lines.

在顺序发散中将一列从一列插入一列的同时序列行。只能插入细线中。
