10、注意plc输出模块的驱动能力能否满足外部负载的要求。
对于频繁通断的负载，应该选用晶闸管输出或晶体管输出，它们属于无触点元件。但晶闸管输出只能用于交流负载，而晶体管输出只能用于直流负载。
中央处理器cpu是核心,它的作用时接受输入的程序并存储程序.扫描现场的输入状态,执行用户程序,并自诊断.

该标准在原先一直相互独立的plc、计算机数字控制、机器人控制以及运动控制领域之间架起了一座桥梁。目前，利用一台类似plc的系统，就可以实现对一个完整的机械设备控制程序的编程。该标准使机器人控制器和运动控制器，不再是相互独立的系统，而是集成为控制系统的一部分。将运动控制和逻辑控制在一个软件包中实现，所带来的重要的优势包括：在逻辑控制器和运动引擎之间无限制的数据交换，而且没有延迟，在传统的系统中，延迟会影响设备的性能。事实上，现在利用机械设备控制器就可以在机器人和外设的伺服轴之间实现完美的同步，这在以前controlengineeringchina，只能在机器人控制领域才可以实现
顺序功能流程图语言是为了满足顺序逻辑控制而设计的编程语言。编程时将顺序流程动作的过程分成步和转换条件，根据转移条件对控制系统的功能流程顺序进行分配，一步一步的按照顺序动作。每一步代表一个控制功能任务，用方框表示。在方框内含有用于完成相应控制功能任务的梯形图逻辑。这种编程语言使程序结构清晰，易于阅读及维护，大大减轻编程的工作量，缩短编程和调试时间。用于系统的规模校大，程序关系较复杂的场合。图5是一个简单的功能流程编程语言的示意图。
