PLC automatic process control system to control production ,testing process ,supply reliable working data for production scheduling and management.

This system is mainly made up of industry computer and PLC control cabinet and on-site control cabinet it is switched by the remote control and local control in order to achieve operational consolidation, centralized management, control, dispersion, risk dispersion.

The PLC main controller CPUintegration hasindustrial Ethernet interface that connect PLC and computer to industrial Ethernet switches. It not only achieve communications between the computer and PLC to real-time display and monitor production process on computer, but also get Ethernet interface on switch to associate the system into the factory management network, then the system can uploaded data to the management network. Last, the automatic control of whole factory come to true.

The industry computer is human-computer interaction interface to achieve control. It accepts the data carried out by the PLC, first it establishes a dynamic database, and then configuration software disposes it timely .Last ,the function of dynamic display, automatic control, data logging, reporting, analysis, curve query is achieved .

Main content of PLC system control:

Ø Chain start-stop and fault alarm of computer control equipment automatically.

Ø The system self-diagnostic function, the external signals recognition

Ø Automatic inspection, diagnosis, and treatment of Information

Ø Automatically display, record, print various fault of voice broadcasting equipment

Ø Real-time dynamically display and control of whole production process

Ø It can be voice communications, such as drive notification, fault location liaison and production scheduling

Ø It can print statements or copy images manually or automatically.

Ø All on-site sensors of stall, plug, wandering and high-performance devices complete signal detection and a variety of real-time control together.

Ø Data transmission and communication networks

Ø Data records, reports, printing and statistical analysis of flow balance and packing balance

Ø Level monitoring alarm and prompt

Ø Speed measurement, fault alarm and chain control of bucket elevator

Ø Plug-proof, fault alarm and interlock control of all system

Ø Important statistical analysis of power consumption, extraction rate, the cost of groups

Ø Remote computer network query and control of management staff
