What is a teaching device? It is also called "a teaching Programmer", which is a handheld device used in robot control. In the motion control system of robots, the teaching device is connected to the control cabinet or motion controller through communication cables. By setting motion parameters and programming the robot's motion path, the robot can work according to the programmed process file, and it allows for real-time monitoring, adjustment, and emergency stop of the robot's motion. It can also be configured to a manual operation mode for real-time control of the robot's movement.

With the continuous trend of automation from semi-automatic to fully automatic, the whole industry’s requirements for the "brain" of automation - control system are increasingly high, not only need to have easy-to-use operating system, but also to achieve independent operation in the production process, adaptive control, etc.

Both Industry 4.0 and the Internet of Things (IoT) require high networking and powerful communication capabilities between devices and servers. EtherCAT is a relatively mature industrial Ethernet fieldbus, specifically used for motion control applications. Compared to traditional industrial fieldbuses, EtherCAT has many advantages such as high stability, high real-time performance, high integration, strong scalability, and easy installation. It breaks through the system limitations of traditional Ethernet solutions and is widely used in the field of industrial control.

The industrial data acquisition and control system mainly consists of two major structures. The first is the data acquisition system, which primarily uses FPGA processors for high-speed acquisition and obtaining of industrial protocol data; the second is the embedded control platform, which mainly uses ARM processors as the main control center for coordinating and managing the modules, resource scheduling, and at the same time receiving the data from FPGA, result visualization, and human-computer interaction. Using communication modules, the acquired data is transmitted to industrial MES+ERP systems, which not only reduces the risk of manual data entry but also saves on human resources.

In recent years, with the development of information technology, the requirements for industrial intelligence and intelligent construction machinery have also been increasing, leading to a growing demand for specialized controllers for various types of construction machinery hosts. However, the mainstream construction machinery controller hardware configurations currently on the market are generally low, and the computing power cannot meet the needs of intelligent control; the capacity of the main chips is too small to save large amounts of operational data for long periods of time, and the software part does not have the ability to analyze data; at the same time, there is a lack of support for peripheral devices, with fewer interface functions and limited functionality for expandable applications.

EtherCAT is an industrial Ethernet technology that is mostly used in servo motors. Because it is based on Ethernet technology, EtherCAT is much faster in speed compared to CAN bus. EtherCAT can reach a speed of 100M, while CAN only has 1M. In addition, EtherCAT also features low latency and precise synchronization.
