Premium + TWIDO + ATV31 scheme hardware structure
Scheme schematic
The first layer control is similar to the second layer control principle. Twido is used for conventional IO process control. The exchange of information with Premium Ethernet is used to control the ATV31 frequency converter (built-in CANopen slave port) through Premium CANopen communication. Operations such as resetting and reading the inverter status, use bus communication, and do not use analog control, saving costs for customers.

Advantages of this solution
This control scheme uses Schneider's Modicon Premium automation platform and Unity software and the ATV31 inverter under TE. Premium was released in 1997 and sells approximately 20,000 CPUs annually, with sales of approximately 77 million euros. Premium is sold and supported in 130 countries. The new 32-bit structure and enhanced performance include 57-3634M CPUs including Ethernet ports as built-in ports. , Can be communicated with the inverter and ERP separately, with stronger functions, increased performance, and increased data and program capacity. The newly designed super processing power reduces cycle time, provides more capacity for programs and data, and enhances the simulation volume and process processing capacity. ATV31 frequency converter, compact structure, integrated EMC filter, built-in MODBUS and CANopen communication ports, allows the use of CANopen communication control, easy to use.
This control scheme uses CAN bus communication: it has a high bit rate (up to 1Mb); high resistance to electromagnetic interference; the use of short frames increases real-time and anti-interference capabilities. The communication mechanism of CANopen is simple, which can reduce the complexity of the device. It can manage 128 devices (1 master station + 127 slave stations). The CANopen protocol is suitable for all mechanical embedded networks and is the most important network standard in Europe.
Premium CPU and TWIDO use Ethernet communication, and can be directly connected with the general company's ERP system.
In short, it is similar to the vertical advertising machine. it can charge everyone at any time to meet people's need.
It uses electronic ultra-white tempered glass with a transmission rate of 95%, beautiful interactive color, excellent image quality, 3D surround sound, and full-featured remote control operation. Used in government companies, hotels, restaurants,street ,restaurant etc.
