(3)Sequence,Timing,and Relationships
Next,determine the sequence in which control operations are to occur and the relative timing of the operations.Identify the physical relationships between the I/O devices as well as the kinds of responses that should occur betwween them.
For instance,a photoelectric switch might be functionally tied to a motor by way a counter within the PC.When the PC receives an input from a start switch,it could start the motor.The PC could then stop the motor when the counter has received five input signals from the photoelectric switch.Each of the related tasks must be similarly determined,throughout the entire control operation.

顺序、定时和相互关系
Next,determine the sequence in which control operations are to occur and the relative timing of the operations.
接着,确定待发生控制事件的顺序及操作的相对时序.
Identify the physical relationships between the I/O devices as well as the kinds of responses that should occur betwween them.
识别I/O设备间的物理关系及响应信号.
For instance,a photoelectric switch might be functionally tied to a motor by way a counter within the PC.
例如:光电开关可能通过PC内的计数器被固定到马达上以实现一定功能.
When the PC receives an input from a start switch,it could start the motor.
当PC从启动开关接收到输入信号时,启动马达.
The PC could then stop the motor when the counter has received five input signals from the photoelectric switch.
当计数器从光电开关接收到5个输入信号时,PC将终止马达工作.
Each of the related tasks must be similarly determined,throughout the entire control operation.
每个相关任务在整个控制过程中确定方式类似.
