ABBAC900F学习笔记315：IEC61131-3编程-SFC编程-15
Enable 允许 Enable can be set for the SFC program via a freely configurable Boolean variable. The current Enable state can be routed to a further Boolean output variable. The Enable variable and the Enable operator parameter are interconnected via an OR function.
可以为SFC程序的“允许”配置一个BOOL变量。可以将当前的允许状态输出到BOOL变量。允许变量和允许运算符参数可以通过OR互联。
Manual/Auto
手/自动		 The operating mode can be set via two freely configurable Boolean variables. The same operating philosophy applies as for the controller function blocks. The variables are dominant vis-a-vis the modes operation parameter, the Manual variable is dominant vis-avis the automatic variables.
操作方式可以通过两个可自由配置的布尔变量进行设置。与控制功能块相同的操作理念。变量相对于模式操作参数占主导地位，手动变量相对于自动变量占主导地位。
Operation mode 操作方式 The current mode can also be routed to a freely configurable Boolean output variables. Automatic=TRUE.
当前手自动操作方式输出到BOOL变量。自动 = 真。
Reset 复位 Reset can be effected via a freely configurable Boolean variable. The reset variable and the reset operation parameter are interconnected according to an OR function. The reset signal is
evaluated only in the manual mode.
可以给“复位”配置一个BOOL变量。复位变量和复位操作参数根据 OR 函数互连。复位信号仅在手动模式下进行评估。
TMO state
TMO状态		 The state indicating that the monitoring time has expired on at least one step can be routed to a freely configurable Boolean output
variable. This variable is then also set to TRUE if no TMO message
has been configured.
该状态值指示至少在一个步骤上监视时间超期，该数值输出到BOOL变量。
然后，如果未配置 TMO 消息，则此变量也设置为 TRUE。
