DVP04AD-E2 analog input module receives external 4 points of analog input signals (voltage or current) and converts them into 16-bit digital signals. You can select voltage input or current input by the wiring. In addition, you can access the data in the module by applying FROM/TO instructions or read the average value of channels directly by using MOV instruction (Please refer to allocation of special registers D9900 ~ D9999).EN DVP04AD-E2 is an OPEN-TYPE device. It should be installed in a control cabinetfree of airborne dust, humidity, electric shock and vibration. To preventnon-maintenance staff from operating DVP04AD-E2, or to prevent an accident from damaging DVP04AD-E2, the control cabinet in which DVP04AD-E2 isinstalled should be equipped with a safeguard. For example, the control cabinet in which DVP04AD-E2 is installed can be unlocked with a special tool or key. EN DO NOT connect AC power to any of I/O terminals, otherwise serious damagemay occur. Please check all wiring again before DVP04AD-E2 is powered up. After DVP04AD-E2 is disconnected, Do NOT touch any terminals in a minute. Make sure that the ground terminal on DVP04AD-E2 is correctly grounded in order to prevent electromagnetic interference.FR DVP04AD-E2 est un module OUVERT. Il doit être installé que dans une enceinteprotectrice (boitier, armoire, etc.) saine, dépourvue de poussière, d’humidité, de vibrations et hors d’atteinte des chocs électriques. La protection doit éviter que les personnes non habilitées à la maintenance puissent accéder à l’appareil (par exemple, une clé ou un outil doivent être nécessaire pour ouvrir a protection). FR Ne pas appliquer la tension secteur sur les bornes d’entrées/Sorties, ou l’appareilDVP04AD-E2 pourra être endommagé. Merci de vérifier encore une fois lecâblage avant la mise sous tension du DVP04AD-E2. Lors de la déconnection de l’appareil, ne pas toucher les connecteurs dans la minute suivante.

PLC对模拟量信号的处理过程及方法模拟量信号是自动化过程控制系统中最基本的过程信号(压力、温度、流量等)输入形式。

系统中的过程信号通过变送器，将这些检测信号转换为统一的电压、电流信号，并将这些信号实时的传送至控制器(PLC)。

PLC通过计算转换，将这些模拟量信号转换为内部的数值信号。

从而实现系统的监控及控制。

从现场的物理信号到PLC内部处理的数值信号，有以下几个步骤：从以上PLC模拟量的信号输入流程可以看到，在自动化过程控制系统中，模拟量信号的输入是非常复杂的。

但是，在现目前的工业现场，对模拟量信号的处理已基本都采用电流信号方式进行传输，相比于电压信号方式，电流信号抗干扰能力更强，传输距离更远，信号稳定。

这里就PLC对模拟量信号的转换过程进行一个简单的分解介绍。

PLC对模拟量信号的转换西门子S7-200SMART PLC模拟量模块对模拟量信号的转换范围台达DVP系列模拟量模块对模拟量信号的转换范围从以上可以看到：1、模拟量信号接入PLC后，PLC将模拟量信号转换为了整型数据，不是浮点数(如西门子-27,648 到 27,648);2、不同品牌的PLC对模拟量转换范围是有差异的(如西门子-27,648 到 27,648;台达-32,384 到 32,384);3、PLC同一个模块对不同类型的模拟量信号的转换范围是一致的(如西门子对±10 V、±5 V、±2.5 V 或 0 到 20mA的模拟量信号的转换范围均为-27,648 到 27,648);故从以上几点我们可以知道，接入PLC的模拟量信号还需要进行再转换处理，才可以得到与实际物理量相匹配的数据;在进行数据转换处理的时候，还应该与使用的PLC模块的处理数据范围相对应。

PLC数据转换处理过程1、模拟量信号与PLC转换数据之间的转换从以上内容知道，从PLC直接读取到的模拟量信号为整型数据，整型数据无法直观的反馈出实际的物理量大小，故为了能够直观的反馈出现场的过程信号情况，还应该将这些整型数据转换为反馈直观真实的浮点数信号。

台达PLC通讯调试方法。

台达PLC出厂通讯格式为，ASCII,9600,7,E,1,支持功能码03H，06H，10H,如用串口调试程序向PLC（站号为1）的D0写H1770,ASCII字符为: “: 010610001770620d0a”应在串口调试程序中写入的16进制代码为: 3A 30 31 30 36 31 30 30 30 31 37 37 30 36 32 0D 0A 注意阿ASCII模式下字符0对应16进制30H,1对应16进制31H ，依次类推......你的串口协议是对的，与PLC的默认协议完全相符，PLC不用再作协议设定。

你发送的数据中有几个错误：1、尾码不是0A0D，而应是0D0A。

2、16进制数据与ASCII码混在了一起，"010*********"是ASCII码，应全部转换为16进制。

正确的字符串数据是="："+"010*******"+LRC码（"EA"）+CR(0D)+LF(0A)转换为16进制="3A3031303130343030313045410D0A"，你把引号内的内容复制到你的串口调试软件中，按16进制发送试试。

我已经试过了，返回数据是=":01810777" (3A 30 31 38 31 30 37 37 37 0D 0A)我是一个PLC初学者,在Micro Programmable Logic Controller FC4A使用手册中，遇到一个问题：在17－2中电缆线连接器脚位表格下，有一个“注：准备连接埠1的电缆显示，请不要插入第6和7针。

如果第6和7针连接在一起，便无法使用使用者通讯。

”但是现在所配制的电缆就是第6和7针之间的电阻值接近于0。

在WindLDR中，简单输入输出和定时、计数器可以编程并下载到PLC中正常运行，在使用TXD和RXD指令时按照手册中所述进行梯形图编程时，无法运行，接收状态码显示15，无法进行串行通讯。

PLC如何使⽤模拟量？接线加程序实例讲解⾸先我们了解⼀下什么是数字量和模拟量？为什么PLC需要使⽤模拟量？数字量数字量是物理量的⼀种。

它们的变化在时间上是不连续的,总是发⽣在⼀系列离散的瞬间。

这⼀类物理量叫做数字量。

也就是离散量，指得是分散开来的、不存在中间值的量。

模拟量模拟量是指变量在⼀定范围连续变化的量；也就是在⼀定范围（定义域）内可以取任意值（在值域内）。

数字量是分⽴量，⽽不是连续变化量，只能取⼏个分⽴值，如⼆进制数字变量只能取两个值。

那么对于实际的⼯业应⽤⽽⾔，数字量和模拟量都是必不可少的。

因为在⼯⼚的⾃动化控制中，我们需要对温度，压⼒，液位，深度等等数据进⾏监控并控制。

⽐如说⼀个锅炉的控制，我们需要⽔烧到⼀定温度，⼀般来说该温度是可调的，⽐如说50摄⽒度，或者70摄⽒度，⽽数字量则不能满⾜这些条件。

再举个例⼦，⼀些化⼯企业需要测量液体的酸碱度，那么酸碱度不可以⽤数字量的0或者1表⽰，只能使⽤模拟量，PH6.5,PH7.0等等才可以清晰的描绘出实际的数据。

那么学习模拟量其实应该学习两部分内容；⼀硬件；硬件包括选型和接线，选型就是针对不同的⼯况选择不同的模拟量以及PLC，⽐如说模拟量使⽤0-10V，4-20ma还是0-20ma还是特殊的热电偶信号等等。

其次就是接线，⼤家不要⼩瞧了接线，针对不同的PLC有不同的接线⽅法。

对于西门⼦S7-300系列来说，我们需要使⽤拓展模块，打开西门⼦STEP7,徐楠则合适的PLC和模拟量模块，并将模块添加进去。

对于PLC⽽⾔，每⼀个模拟量都有⼀个固定的地址，这个地址是可以在程序中进⾏识别并计算的，续智能则合适的地址并添加进去。

根据现场设备，选择合适的量程，如果是测量温度的话需要使⽤特定的温度模块，并选择合适的温度信号。

对于温度的控制，我们以前⽂章有介绍过，需要的朋友可以去寻找。

对于电压信号，有多种可选类型，可根据实际设备的信号类型进⾏选择。

⽐如说-10V—10V，-5V—5V，-1V—1V，1-5V。

PLC模拟量输入输出方法模拟量的输入方法有两种。

1.用模拟量输入模块输入模拟量把模拟量输入给plc最简单的方法是，用模拟量输入模块（单元），简称AD单元。

模拟量输入模块的功能是将模拟过程信号转换为数字格式。

模拟量输入流程是通过传感器把物理量转变为电信号，这个电信号可能是离散性的电信号，需要通过变送器转换为标准的模拟量电压或电流信号，模拟量模块接收到标准的电信号后通过A/D转换，转变为与模拟量成比例的数字量信号，并存放在缓冲器里，待CPU读取模拟量模块缓冲器的内容，并传送到指定的存储区中待处理。

使用模拟量输入模块时，要了解其性能，主要的性能如下。

·模拟量规格：指可承受或可输出的标准电流或标准电压的规格，一般多些好，便于选用。

·数字量位数：指转换后的数字量，用多少位二进制数表达。

位越多，精度越高。

·转换路数：只可实现多少路的模拟量的转换，路越多越好，可处理多路信号。

·转换时间：只实现一次模拟量转换的时间，越短越好。

·功能：指除了实现数模转换时的一些附加功能，有的还有标定、平均峰值及开方功能。

2.用采集脉冲输入模拟量PLC可采集脉冲信号，可用于高速计数单元或特定输入点采集。

也可用输入中断的方法采集。

而把物理量转换为电脉冲信号也比较方便。

模拟量输出方法有三种。

1.用模拟量输出模块（单元）控制输出为使控制的模拟量能连续、无波动地变化，最好的方法是用模拟量输出模块。

模拟量输出模块的功能是将数字输出值转换为模拟信号，简称DA单元。

模拟量输出模块的参数有诊断中断、组诊断、输出类型选择（电压、电流或禁用）、输出范围选择及对CPU STOP模式的响应。

模拟量输出流程是：CPU把指定的数字量信号传送到模拟量模块的缓冲器中，模拟量模块通过D/A转换器，把缓冲器的内容转变为成比例的标准电压或电流信号，标准电压或电流驱动相应的执行器动作，完成模拟量控制。

使用模拟量输出模块时应按以下步骤开展：[1]选用。

DVP-PLC特殊模块怎么使用DVP-PLC特殊模块怎么使用？成都永浩机电工程技术有限公司做了以下总结供大家参考：一、模拟输入模块DVP04AD/DVP06AD在自动化的领域中，有许多的测量单元，是以模拟信号的模式进行传送的动作，且以电压-10~10V 与电流-20~20mA 范围最为常见。

若要将模拟信号作为PLC 控制演算的参数，则需转换为数字量。

例如：电压-10~10V。

经由AD 模块的转换成为-8,000~+8,000 的数值范围后，PLC 再以FROM/TO 指令对AD 模块的CR 寄存器进行读写的动作，所传回至PLC 的信号为K-8,000~ K8,000 的数字量，即可提供PLC 进行运算处理。

DVP04AD (DVP06AD)模拟信号输入模块可接受外部4 (6)点模拟信号输入(电压或电流皆可)，并将其转换成14 位的数字信号。

通过主机以指令FROM/TO 来读写模块内的数据，摸块内具有49 个CR (Control Register)寄存器，每个寄存器为16bits。

可经由配线选择电压输入或电流输入。

电压输入范围±10V (±8,000，分辨率为。

电流输入范围±20mA (±4,000，分辨率为5μA)。

二、模拟输出模块DVP02DA/DVP04DA在应用的领域中，有许多的控制信号，是以模拟信号的模式进行控制，且以0~10V 与0~20mA范围为最常见的信号范围。

因此需将PLC 数值数据转换为模拟信号来控制周边装置。

例如：PLC 数值数据0~4,000 的范围。

经由DA 模块的转换成为0~10V 的电压值，所输出的电压即可提供周边模拟装置进行控制。

DVP02DA (DVP04DA) 模拟信号输出模块，可通过DVP-PLC 主机程序以指令FROM/TO 来读写DVP02DA (DVP04DA) 模拟信号输出模块的数据。

模块内具有49 个CR (Control Register) 寄存器，每个寄存器有16bits。
