With the development of PLC skills, its data storage area is becoming larger and larger. For example, dweison PLC, its data storage area (DM area) can reach 9999 words. Such a huge data storage area can store a large amount of data. Data collection can use counter to record the number of pulses collected, and transfer to DM area in time-keeping. Data collection can also be used as a/d unit. When analog quantity is transformed into digital quantity, it is then transferred to DM area on time. PLC can also be equipped with small printers, timing DM data out.
PLC can also communicate with the accounting machine, and the data in DM area can be read out by the accounting machine, and then processed by the accounting machine. At this time, PLC becomes the data terminal of the accounting machine.
The power users used PLC to record the user's power consumption in real time to complete the charging method of different time and different pricing, and encouraged the users to use more electricity in the low-level of electricity consumption, and to achieve the purpose of reasonable power use and saving power.
5. For signal monitoring
PLC self-test signal is many, and many internal equipment are also available. Most users do not give full play to its effect. In fact, it can be used to monitor the PLC operation itself or monitor the control target. It is necessary to monitor and further diagnose a disorderly control system, especially the automatic control system. It can reduce the system defects, find out the faults or find them, and improve the cumulative uniform and even trouble free operation time, reduce the time of fault correction and improve the reliability of the system.
6. For networking, communication
PLC networking and communication can be very strong, and new networking construction is constantly launched.
PLC can be connected with personal accounting machine for communication. It can participate in programming and control PLC, so that PLC can be used more conveniently.
In order to give full play to the effect of the accounting machine, a computer can be used to control and handle multiple PLC, and 32 can be used. Also, one PLC can communicate with two or more accounting machines to communicate information to complete more monitoring of PLC control system. PLC and PLC can also communicate, can one-on-one PLC communication, several PLC communication, can be more than dozens, hundreds.
PLC, intelligent instrument and intelligent performance equipment (such as frequency converter), can also communicate with each other through Internet, exchange data and operate each other. It can be connected into long-distance control system, and the system scale can be as large as 10km or more. Can form part of the network, not only PLC, but also advanced accounting machine, various intelligent equipment can also enter the network. Bus networks can be used, or ring networks can be used. The net can also be set up. The network and the network can also be bridged. The network can arrange countless PLC, accounting machine and intelligent equipment in a network. The nodes between the networks can communicate and exchange information directly or indirectly.
Networking and communication are used to the needs of CIMS and intelligent chemical plants. It can make industrial control from point to line to surface (aero), and make equipment level control, production line control and factory management layer control be integrated into a whole, and thus can create higher benefits. This infinite and beautiful vision has become more and more clear to our generation.
The above application is focused on the quality. In terms of quantity, PLC has large and small. So its control scale can also be large and small. Small only control one device, even a part, a site; Large control of multiple equipment, one production line, so that all the factories. Can say that industrial control of the large and small occasions, can not be separated from PLC.
