What is the difference between FANUC system and Mitsubishi system?

FANUC system is a product of Fujitsu Corporation of Japan, and its Chinese translation is usually FANUC. FANUC system has a very long history in the Chinese market. There are many types of products in use. The most widely used products are FANUC 0, FANUC16, FANUC18, FANUC21, etc. Among these models, the most widely used is FANUC0 series. The system adopts a large number of modular structures in its design. This structure is easy to disassemble and assemble, and each control board is highly integrated, which greatly improves reliability and is easy to repair and replace. FANUC system has designed a relatively sound self-protection circuit. PMC signals and PMC function instructions are extremely rich, which is convenient for machine tool manufacturers to compile PMC control programs and increases programming flexibility. The system provides serial RS232C interface and Ethernet interface, which can complete data transmission between PC and machine tools. FANUC system has stable performance and friendly operation interface. The overall structure of each series of the system is very similar, with a basically unified operation interface. FANUC system can be used in a wide range of environments, and the requirements for external conditions such as voltage and temperature are not particularly high, so it has strong adaptability. In view of the above characteristics, FANUC system has a wide range of customers. The team of operators using this system is very large, so it is necessary to understand some of the software and hardware characteristics of the system.

Main features of Mitsubishi

① Flexible structure

Not restricted by the environment, the network can be established as long as there is electricity, and the number of access ports can be flexibly expanded to keep the resource utilization rate high, which is comparable to WLAN in terms of mobility.

② High transmission quality, fast speed, and stable bandwidth

You can watch DVD movies online smoothly, and the 14Mbps bandwidth it provides can provide guarantees for many application platforms. The latest power line standard HomePlug AV has a transmission speed of 200Mbps; in order to ensure QoS, HomePlug AV uses time division multiple access (TDMA) and carrier sense multiple access (CSMA) protocols with conflict detection function. The combination of the two can well transmit streaming media.

③ Wide range

The ubiquitous power line network is also an advantage of this technology. Although wireless networks can be built without breaking walls, for high-rise buildings, it is necessary to deploy N multiple APs to meet the needs, and the existence of signal blind spots cannot be avoided. The power line is the most basic network, and its scale is unmatched by any other network. As a result, operators can easily penetrate this network access service to every place with power lines. Once this technology enters the commercialization stage, it will bring great development space for the popularization of the Internet. End users only need to plug in the power cat to access the Internet, receive programs on TV channels, make calls or video calls.

④ Low cost

Fully utilize the existing low-voltage distribution network infrastructure, without any wiring, saving resources. There is no need to dig trenches and drill holes through walls, which avoids damage to buildings, public facilities, and home decoration, and also saves manpower. Compared with traditional networking technology, PLC has lower costs, shorter construction period, and stronger scalability and manageability. At present, in places where power broadband Internet access has been opened in China, the monthly subscription fee is generally around 50-80 yuan/month, which is the same price as the monthly subscription of ADSL in many places.

⑤ Wide application

PLC, as an access technology that uses power lines to form a network, provides a solution for the "last mile" of broadband networks and is widely used in residential areas, hotels, office areas, monitoring and security, etc. It uses power lines as a communication carrier, making PLC extremely convenient. As long as there is a power socket in the room, you can immediately enjoy 4.5~45Mbps high-speed network access without dialing, to browse the web, make calls, and watch online movies, thus realizing the "four networks in one" that integrates data, voice, video, and power.
