AB C1CPU-4S-07 module
6. With the integration and development of IT and OT technology, the industrial Internet of Things has become the trend of the times, and the related technologies of PLC communication and the Internet of Things will be popular in the future. Common PLC controller communication includes communication between PLC controllers and communication between PLC controllers and other intelligent devices. With the development of industrial control automation, all PLC controller manufacturers attach great importance to the communication function of PLC controllers and have launched their own network systems. The new PLC controller has a communication interface, which is very convenient for communication. Miniaturization and integration will be higher and higher. With the requirements of the market for miniaturization and integration, PLC technology will be more integrated into industrial, automotive, communications and other products. PLC products are characterized by control and data processing. While meeting the functions, the process requirements are also more detailed. With the development of intelligent factories and the Internet of Things, new requirements have been put forward for the technical development of PLC in the fields of joint control of factory equipment, data interaction between PLC and mainframe and other intelligent products, and big data application. This is a new opportunity and a huge challenge. This requires that PLC products have strong environmental adaptability, stability and reliability, can easily access various networks while maintaining a high cost performance ratio, and give full play to the role of PLC products in data acquisition and data interaction.
(1) Convenient configuration: determine which PLC to use, which type, which module to use, and how many modules to use according to the needs of the control system. After confirmation, order and purchase from the market.
(2) Easy installation: PLC hardware is easy to install and assemble. The external wiring has a connector, which is simple to connect. When replacing the module after one connection, the connector can be installed on the new module without wiring. Do not connect any internal wires, just make some necessary DIP switch settings or software settings, and prepare user programs to work.
(3) Convenient programming: Although there are no actual relays, time relays and counters in PLC, these devices actually exist through the program (software) and system memory. The number is unimaginable for relay control system. Even for small PLCs, the number of internal relays can be counted in thousands, and the number of time relays and counts can also be counted in hundreds. Moreover, the contacts of these relays can be used * * times. There are so many internal logic devices in PLC that users can use them without any restrictions. Only the entry and exit points are considered. It doesn’t matter how much this internal access point is used. The number of control points of large PLC can reach more than 10000. How can there be such a large real system? If it is not enough, it can also be controlled online without any restrictions. The command system of PLC is also very rich, which can easily realize the control of various switching values and analog values. The PLC also has a memory area for storing data, which can store all the information to be saved in the control process In a word, because of the strong function of PLC, the restriction to play its role in the control system is not the PLC itself, but people’s imagination, or other supporting hardware facilities.
