对于新行业而言，譬如风电、太阳能等新能源领域，发展迅速，但对全局而言，仍然是星星点点，没有办法成为影响全局的助推力。新市场，还未形成。

（4）PLC的输出负载可能产生干扰，因此要采取措施加以控制，如直流输出的续流管保护，交流输出的阻容吸收电路，晶体管及双向晶闸管输出的旁路电阻保护。
加隔离变压器，主要是针对来自电源的传导干扰，可以将绝大部分的传导干扰阻隔在隔离变压器之前。
2）软件模拟法是在PLC中另外编写一套模拟程序，模拟提供现场信号，其简单易行，但时效性不易保证。模拟调试过程中，可采用分段调试的方法。，并利用编程器的监控功能。
循泵与出口蝶阀处于相关的连锁状态。为防止循泵的空转，倒转引起泵的损坏，循泵的启停由出口蝶阀决定，并且考虑到系统有没充水的条件。
输入端的一次电路与二次电路之间采用光电耦合隔离。二次电路带R-C滤波器，以防止由于输入触点抖动或从输入线路串入的电噪声引起可编程控制器的误动作。
(5)采用模块式结构：这种结构有助于在故障情况下短时修复。因为一旦查处某一模块出现故障，就能迅速更换，使系统回复正常工作，也有助于加快查找故障原因。

开关量输出模块的输出电流(驱动能力)必须大于PLC外接输出设备的额定电流。用户应根据实际输出设备的电流大小来选择输出模块的输出电流。如果实际输出设备的电流较大，输出模块无法直接驱动，可增加中间放大环节。
