013 theorotically review of s7 1200 analog i_o

您好,在本视频中,Reveler 模拟输入和输出理论上模拟模块是模拟信号的信号转换器。
Hello, in this video, reveller analog inputs and outputs as theoretically analog modules are signal transducers for the analog signals.

这很重要,当模拟变量已由模拟输入模块转换为数字值时,CPA 可以使用这些模块来处理模拟变量。
This is important and the CPA can use these modules to process analog variables when this has been converted by analog input modules to digital values.

想象一下我们有这样的模拟输入。
So imagine we have analog input like this.

这是模拟的,但它只是零或一。
This is analog, but then it just zeroes or ones.

好的,所以你只能理解零和一。
OK, so you can understand just zeros and ones.

因此,我们会将该值转换为例如 0 到 10 伏的数字值,并且模拟模块有两个、四个或八个通道,对应于四个、八个或 16 个字节。
So we will convert this value to, for example, zero to 10 volt to digital values and analog modules are available with two, four or eight channels corresponding to four, eight or 16 bytes.

这真的很重要。
This is really important.

所以在右侧,您将看到模拟模块。
So on the right side, you will see the analog module.

嗯,一个例子描绘了数字侧的模拟值。
Um, one example picture a digital side, analog value.

在内部表示为十六点无数据类型整数。
Is represented internally as a sixteen point no data type integer.

那么,当您在 Simon 的 CPA 中读取解锁值时,这意味着什么,您将把它们全部读取为整数。
So what does that means when you read unlock value in your CPA, in Simon's, you will read them all as integer.

好的,当您尝试读取 CPA 中的解锁值时,这一点非常重要。
OK, this is really important when you try to read unlock value in your CPA.

这是整数值。
This is integer value.

这真的非常非常重要。
This is really, really, really important.

测量田庄的正负,正负 Tannenwald 和五倍二十二点五卷和一点二十五跳马和零到 2000 万。
The measuring Granges is plus and minus, plus and minus Tannenwald and Five-fold twenty two point five vol and one point twenty five vault and zero to 20 million.

Sawford 或延时臂与内部表示中的 12 位加号分辨率对应于电压范围正负 10 内从负二万七千六百四十八到正二万七千六百四十八的数值。
Sawford or timelapse arms correspond with the resolution of 12 bits plus sign in the internal representation to a numerical value from the minus twenty seven thousand six hundred forty eight to plus twenty seven thousand six hundred forty eight in the voltage range plus and minus 10.

分辨率是 14 节拍,速率范围从相同的负二万七千六百四十八到二加二和七千六百四十八。
What the resolution is 14 beats with a rate that range from the same similar minus twenty seven thousand six hundred forty eight and two plus two and seven thousand six hundred forty eight.

那么这意味着什么呢?
So what does that mean?

会是这样的。
It will be like this.

好吧,零坦南瓦尔德。
OK, zero Tannenwald.

而在这之中。
And in this.

我们将得到方程。
Equation we will get.

这个还可以。
This one is OK.

最大值。
The maximum value.

二万七千六百四十八。
Twenty seven thousand six hundred forty eight.

这是模拟值和数字值的等式,模拟输入可以是输出模块中的名称、模拟输出和模拟量。
This is the equation of your analog value and digital value and analog inputs can be this once the names and analog outputs and analog in an output modules.

好的,我们将用硬件做一个示例,我们将阅读模拟帖子,并将写入门户中的模拟输出。
OK, so we will do an example is with the hardware and we will read analog post and we will write to analog outputs in the portal.

但这只是本视频完成的有关模拟输入和输出的理论信息。
But this is just a theoretical information about analog inputs and outputs finished for this video.

下一个视频见。
See you in the next video.
