A universal interface between dynamic systems. This interface can be embedded in the control system, and the control system itself can also be located on the transmission device (sometimes called

As "intelligent transmission" or "intelligent transmission").

A variety of physical interfaces (analog and digital input and output, serial and parallel interfaces, fieldbus and network) can be used. For some applications

Field of application (e.g. motion control) and device category (e.g. standard transmission, positioning device), the protocol set based on a specific physical interface has been determined

Certainly. The realization of related transmission device and application program interface is proprietary technology, and the difference is very big.

Function and data method, this method does not depend on the used transmission protocol and communication interface. Its goal is to have common functions and objects,

It is suitable for general transmission models mapped to different communication interfaces. This allows personnel without any professional knowledge of transmissions to implement in the controller

Now general motion control (or speed control or transmission control application).

Several reasons for defining a common interface.

For manufacturers of transmissions.

---It is easier to support system integrators;

---General terminology, it is easier to describe the transmission function;

---The choice of transmission does not depend on special support.

For control device manufacturers.

---The influence of no bus technology;

---Easy device integration;

---Does not depend on the transmission supplier.

For system integrators.

---Reduce the workload of device integration;

---There is only one reasonable modeling method;

---Does not depend on bus technology.

Designing motion control applications with several different transmissions and specialized control systems requires a lot of work. Understand certain task groups

The function definition of the software and the system software programming will consume a lot of project resources. In some cases, transmissions cannot share the same thing

理interface. Some control devices only support one interface, but this interface is not supported by a specific transmission device. On the other hand, the prescribed work

Energy blocks and data structures are usually incompatible. To deal with this situation, the system integrator needs to write a special interface program for the application software.

It should not be their responsibility.

Certain applications require interchangeability of devices or integration of new devices into existing configurations. It also faces various incompatibility

Solution. It may not be possible to make a scheme conform to the transmission protocol and also meet the specific requirements of the manufacturer. This will reduce the response

Choose the most suitable device and the degree of freedom of the unit for the occasion. This unit will be suitable for a specific physical interface and be supported by the controller at the same time.
