Mitsubishi PLC network product structure

Mitsubishi PLC PLC network structure Mitsubishi network PLC network structure Mitsubishi inherits the traditional used MELSEC network, and make them in such aspects as performance, function, ease of use. Q series PLC to provide clear three-layer network, according to various USES to provide the most suitable network products,

1 layer, information/Ethernet (Ethernet) top layer for the network information system, mainly in the PLC controller, equipment and production management with information transmission between the PC production management, quality management information and equipment operation data, such as the most common use of Ethernet information layer. It can not only connect Windows PC and UNIX workstation, and still can connect various FA equipment. Q series PLC series Ethernet module has the function of the increasing popularity of the Internet to send and receive E-mail, users no matter anywhere in the world can easily send and receive mail production information, to construct the remote monitoring management system. At the same time, use the Internet to the FTP server functions and MELSEC proprietary protocols can easily upload/download the implementation of the program and information transmission.

2 layer, control/MELSECNET / 10 (H) is the middle tier of the network system, in is convenient and between PLC and CNC control equipment such as high speed processing data to each control network. As MELSECNET / 10 of MELSEC control network, with its good real-time performance, simple network setting, no application of network data sharing concept, redundancy and the characteristics of a high loop market evaluation, adopted equipment sets reached the highest in Japan, is also a handful of in the world. And MELSECNET/H not only inherited the outstanding characteristics of MELSECNET / 10, also make the network better real-time performance, data capacity is bigger, further meet the needs of the market. But at present, MELSECNET/H is only can use Q series PLC.

3, equipment/devices cc-link fieldbus layer is the PLC and other control devices and sensors and drive equipment connected field network, the lowest layer of the network for the whole network system. Using CC cc-link fieldbus connection, wiring amount is greatly reduced, increased the system maintainability. And not just ON/OFF switch is the amount of data, also can connect ID systems, bar code readers, frequency converter, man-machine interface, intelligent equipment, from complete a variety of data communication, to the terminal production information management can be implemented, and the centralized management of the state machine movements, make the maintenance working efficiency also have greatly improved. Used in the Q series PLC, CC - Link function better, and use more convenient.

In mitsubishi PLC network for communication, won't feel a kinds of differences and intermittent network, can be carried out across the network between the data communication and application of remote monitoring, modify and debugging work, without considering the level and type of the network.

MELSECNET/H and CC - Link using a loop communication way, periodic automatically receive and send information, don't need special data communication program, simply set parameters. MELSECNET/H and CC - the Link is to use broadcast cycle way of communication to send and receive, so that it can achieve data sharing on the network.

For Q series PLC with Ethernet, MELSECNET/H, CC - Link network, can be in GX Developer software screen set the network parameters as well as a variety of functions, simple and convenient.

In addition, Q series PLC in addition to network has mentioned above, can also support PROFIBUS and Modbus, DeviceNet, ASi and other vendors' network, also can be the RS - 232 / RS - 422 / RS - 485 serial communication, through the data line, telephone line for data transmission and so on the many kinds of communication mode.
