1. The equipment layer/fieldbus CC-Link equipment layer is a field network that connects PLC and other control equipment, sensors and drive equipment, which is the lowest layer of the entire network system. The CC-Link fieldbus connection greatly reduces the number of wirings and improves the maintainability of the system. In addition, not only the data of switching quantities such as ON/OFF, but also intelligent equipment such as ID systems, barcode readers, inverters, and human-machine interfaces can be connected, and the operation efficiency of maintenance can also be greatly improved from the communication of various data to the handling of terminal production information. When used in Q series PLCs, CC-Link has better functions and is easier to use.
2. The control layer/MELSECNET/10 (H) is the middle layer of the entire network system, which is a control network for convenient and high-speed processing data exchange between PLC, CNC and other control equipment. MELSECNET/10, as a MELSEC control network, has won high reviews for its outstanding real-time performance, simple network settings, program-free network data sharing concept, and redundant loops, and the number of devices used is the highest in Japan and few in the world. MELSECNET/H not only inherits the excellent features of MELSECNET/10, but also makes the network more real-time and has a larger data capacity, which further adapts to the needs of shopping malls.
3. The information layer/Ethernet (Ethernet) information layer is the highest level in the network system, which is mainly used to transmit production management information, quality management information and equipment operation data between PLC, equipment controller and production management PC, and the information layer uses the most common Ethernet. It can not only connect to Windows PC, UNIX system operation station, etc., but also to connect to various FA equipment. The Ethernet module of the Q series PLC series has the increasingly ubiquitous Internet e-mail sending and receiving function, and the user can easily send and receive production information e-mails anywhere in the world, and build a long-distance supervision and management system. Together, the FTP server function of the Internet and the MELSEC protocol make it easy to upload/download programs and transfer information.
In addition, in addition to the above-mentioned networks, the Q series PLC can also support the networks of other manufacturers such as Profibus, Modbus, Devicenet, ASi, etc., and can also carry out serial communication such as RS-232/RS-422/RS-485, and carry out data transmission and other communication methods through data lines and telephone lines.
When communicating in Mitsubishi's PLC network, there is no difference in network types and continuity, and data communication between networks and long-distance monitoring, modification, and debugging of programs can be carried out regardless of the level and type of network. MELSECNET/H and CC-Link use a cyclic communication method to send and receive messages automatically and periodically, without the need for a special data communication program, only a simple parameter setting. MELSECNET/H and CC-Link use the broadcast method for circular communication transmission and reception, so that data can be shared on the network. The Ethernet, MELSECNET/H, CC-Link networks used in Q Series PLCs can be easily set for network parameters and various functions on the GXDeveloper software screen.
