Modicon*康 PC-E984-685程序模拟调试
程序模拟调试的基本思想是，以方便的形式模拟产生现场实际状态，为程序的运行创造必要的环境条件。根据产生现场信号的方式不同，模拟调试有硬件模拟法和软件模拟法两种形式。
1）硬件模拟法是使用一些硬件设备（如用另一台PLC或一些输入器件等）模拟产生现场的信号，并将这些信号以硬接线的方式连到PLC系统的输入端，其时效性较强。

可编程序控制器，英文称Programmable Controller，简称PC。但由于PC容易和个人计算机（Personal Computer）混淆，故人们仍习惯地用PLC作为可编程序控制器的缩写。它是一个以微处理器为核心的数字运算操作的电子系统装置，专为在工业现场应用而设计，它采用可编程序的存储器，用以在其内部存储执行逻辑运算、顺序控制、定时/计数和算术运算等操作指令，并通过数字式或模拟式的输入、输出接口，控制各种类型的机械或生产过程。PLC是微机技术与传统的继电接触控制技术相结合的产物，它克服了继电接触控制系统中的机械触点的接线复杂、可靠性低、功耗高、通用性和灵活性差的缺点，充分利用了微处理器的优点，又照顾到现场电气操作维修人员的技能与习惯，特别是PLC的程序编制，不需要专门的计算机编程语言知识，而是采用了一套以继电器梯形图为基础的简单指令形式，使用户程序编制形象、直观、方便易学；调试与查错也都很方便。用户在购到所需的PLC后，只需按说明书的提示，做少量的接线和简易的用户程序编制工作，就可灵活方便地将PLC应用于生产实践。
可编程序控制器一直在发展中，所以至今尚未对其下zui后的定义。电工学会（IEC）曾先后于1982.11；1985.1和1987.2发布了可编程序控制器标准草案的*，二，三稿。
在第三稿中，对PLC作了如下定义：可编程序控制器是一种数字运算操作电子系统，专为在工业环境下应用而设计。它采用了可编程序的存储器，用来在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，并通过数字的，模拟的输入和输出，控制各种类型的机械或生产过程。可编程序控制器及其有关的外围设备，都应按易于与工业控制系统形成一个整体、易于扩充其功能的原则设计。
