plc pace of development in the future

With increasing degree of factory automation and china plc market expanding capacity base, the growth rate in recent years PLC in industrial countries slowed. However, growth in China and other developing very rapidly PLC. Comprehensive relevant information, in 2004 global sales of PLC is about $ 10 billion, in the field of automation occupies a very important position.module plc is a touch imitation of the original relay control principle developed, in the 1970s the PLC only switch logic controller, the first application in the automotive manufacturing industry. It is stored in the implementation of logical, sequential control, timing, counting and arithmetic instructions such operations; and through digital input and output operations to control various types of machinery or production processes.

In recent years, the rapid development of computer technology has been widely applied in all walks of life. However, with the corresponding traditional industrial module plc development cycle is long, repeated use is low, the price is high, difficult to modify and other shortcomings. As more and more automation equipment has been applied, it is for industrial control software is also rising, the traditional industrial control software has been unable to meet user requirements. How convenient use of the software to design flexible and efficient plc temperature module system has become a very important issue.

Plc cpu modules

module plc is the control center of the system, users will be prepared to complete the program is downloaded to the CPU module, plc cpu module starts execution of the user program in a circular manner, each cycle should be read into the process information, logical calculations, the output result of the operation, but also the timing set by the user or the time to deal with communications, high-speed counting, event interrupts the process.
PLC control system, Programmable Logic Controller, programmable logic controllers, a digital computing operation of electronic systems, designed for use in industrial environments and design. cpu modules plcuses a programmable memory for its internal storage procedures, the implementation of logical, sequential control, timing, user-oriented counting and arithmetic operations such instruction, and through digital or analog input / output control of various types of machinery or the production process. Is the core of industrial control.
