目录描述：Hart模拟输出模块

由于 FSK信号的平均值为0，不影响传送给控制系统模拟信号的大小，保证了与现有模拟系统的兼容性。在 HART 协议通信中主要的变量和控制信息由4-20mA传送，在需要的情况下，另外的测量、过程参数、设备组态、校准、诊断信息通过HART协议访问。

如果n轴的整个驱动路径不仅仅是在n-1到n轴之间，而是跨越了n-1甚至n-m，就会造成耦合。例如，如果六轴电机不是固定在5轴结构件，而是装在三轴结构件上再通过传动机构传到六轴，那么在六轴电机静止的情况下四轴和五轴电机的运动都会造成六轴运动。

内在机制也不难理解，因为这种跨周的传动通常是通过轴（shaft），齿轮，皮带，连杆这些机构实现的。在跨越若干轴（axis）的情况下，这些传动机构也必须被分作若干级分级传动。这样，即使驱动电机静止，如果极与极之间发生相对运动，这个运动也会被逐级传递到最终的轴（axis）上，造成不需要的运动。要解耦的话则需要在定量分析耦合之后，根据耦合传动比和方向让驱动电机做出补偿动作，抵消其他轴运动的影响。

在应用层，HART规定了一系列命令，按命令方式工作。它有三类命令，第一类称为通用命令，这是所有设备都理解、执行的命令；第二类称为普通应用命令，所提供的功能可以在许多现场设备（尽管不是全部）中实现；第三类称为设备专用命令，以便于工作在某些设备中实现特殊功能，这类命令既可以在基金会中开放使用，又可以为开发此命令的公司所独有。

Catalog Description: Hart analog output module

Since the average value of the FSK signal is 0, the size of the analog signal transmitted to the control system is not affected, and the compatibility with the existing analog system is guaranteed. In HART communication, the main variables and control information are transmitted by 4-20mA, and additional measurement, process parameters, equipment configuration, calibration, and diagnostic information are accessed through HART if needed.

If the entire drive path of the n-axis is not just between n-1 and N-axis, but across n-1 or even n-m, coupling will occur. For example, if the six-axis motor is not fixed on the five-axis structure, but is mounted on the three-axis structure and then transmitted to the six-axis through the transmission mechanism, then the movement of the four-axis and five-axis motors will cause the six-axis movement when the six-axis motor is stationary.

The internal mechanism is not difficult to understand, because this cross-cycle transmission is usually achieved by shaft, gear, belt, and connecting rod. In the case of spanning several axes, these transmission mechanisms must also be divided into several stages of graded transmission. In this way, even if the drive motor is stationary, if there is relative movement between poles, this movement will be transmitted step by step to the final axis (axis), causing unwanted movement. To decouple, it is necessary to make the drive motor make compensation action according to the coupling ratio and direction after quantitative analysis of the coupling, and offset the influence of other shaft movements.

At the application level, HART specifies a series of commands that work in a command manner. It has three types of commands. The first type is called general command, which is the command that all devices understand and execute. The second category, called common application commands, provides functionality that can be implemented in many (though not all) field devices; The third category is called device-specific commands to make it easier to work on implementing special features in certain devices, which are either open to use in the foundation or unique to the company that developed the command.
