歇了好几天，今天继续学习记录Freelance2019sp1下面SFC编程。

9.5.3 Transition operation dialog

条件操作对话框

Close 关闭	The operation dialog for transitions is closed. 关闭条件操作对话框
Operating mode 操作模式	In the Auto operating mode, the transitions are stepped through by the program. In the Manual operating mode, transitions and steps can be activated by the operator. 在自动操作模式，条件按照程序一步一步进行。在手动操作模式，条件和步骤可以由操作员激活。
Transition criteria 条件判据	This section of the operating dialog is used to influence the manner in which the selected transition is made. In the Auto operating mode, transitions are always made in the Calculated mode. 对话框的这一部分用于所选条件的影响方式。在自动操作模式，条件通常是计算模式。
Normal 通常	The transition is made in the calculated mode. 条件使用计算模式。
Blocked 阻止	The transition is blocked. The transition is not made even if the transition criteria are fulfilled. 条件被阻止，即使条件满足，也不会进行到下一步。（卡在这里不进行下去）
Force 强制	Immediately after the transition is enabled, the transition is made, independent of the transition criteria. The processing of the transition is controlled by the Options setting of the SFC (refer to Operation dialog SFC program). Forcing is also possible for a blocked transition. 启用条件后，立即到下一步，独立于条件判据（也就是说不管条件书不是满足，跳转到下一步）条件的处理由SFC设置选项控制（参见SFC程序操作对话框）强制也可能用于阻止条件。

9.5.4 Step states

步骤状态

Steps in the Freelance system can have the states inactive, active, was active and faulty.

Freelance系统中步骤的状态有未激活、激活、激活过了，错误 四种。

inactive 未激活	A step is inactive when it is not run through during a cycle. While a step is inactive, the programs linked to it are not executed. 当步骤未在循环中运行时，该步骤处于未激活状态。当步骤处于未激活状态时，不会执行链接到该步骤的程序。
active 激活	A step is set to the active state when the transition criteria of the previous transition have been fulfilled. Once a step is active, programs linked to it, are executed. 当满足上一个条件时，步骤将设置为活动状态。一旦步骤处于活动状态，就会执行链接到该步骤的程序。
was active 激活过了	After a step has been run through during a cycle, the step goes from the active state to the was active state. 在一个循环中运行一个步骤后，该步骤将从活动状态变为活动过状态。
faulty 故障	The monitoring time of a step has been exceeded. 已超过步骤的监视时间。
