(2)随着国外PLC技术的日益发展,其应用也越来越广泛,其范围通常可分成五大类型
①顺序控制
这是现今PLC应用广泛的领域,可以取代传统的继电器顺序控制可以用于单机、多级群控制式生产自动线控制。如:注塑机、印刷机械、组合机床、装配生产线、包装生产线、电镀车间及电梯控制线路等等。
②运动控制
PLC制造商目前已提供了拖动步进电机式伺服电机的单轴式多轴位置控制模块。在多数情况下,PLC把描述目标位置的数据送给模块,模块移动一轴式数轴到目标位置。当每个轴移动时,位置控制模块保持适当的速度和加速度,确保运动平滑。运动的编程可用PLC的语言完成,通过编程器输入。
③过程控制
PLC能控制大量的物理参数。例如:温度、压力、速度和流量。PID(Proportional-Integral-Derivative)模块的提供使PLC具有了闭环控制的功能,即一个具有PID控制能力的PLC可用于过程控制。当由于控制过程中某个变量出现偏差时,PID控制算法会计算出正确的输出,把变量保持在设定值上。
