Description

A kind of Programmable Logic Controller

Technical field:

The utility model relates to a kind of Programmable Logic Controller.

Background technology:

Programmable Logic Controller is a kind of electronic system of digital operation, it adopts a class programmable memory, for the computing of internally stored program actuating logic, sequential operation, regularly, calculate and the user oriented instruction such as arithmetical operation, and by numeral or simulating signal input, export the various types of machinery of control or production run.Small-sized programmable controller the most frequently used at present mainly adopts unified bus communication or respective communications protocol, needing to differ from various protocols simultaneously, the device talk that disturbs rank different time adaptability and reliability all poor, and conventional small-sized programmable controller is not generally with analog input/output interface, usually need to add analog input/output module separately, cost is caused to increase and installation volume increase, analog quantity conversion efficiency also decreases, and the Distributed Control System (DCS) of general single Programmable Logic Controller or multiple stage composition can not be satisfied the demand, the control overflow become increasingly complex can not be met, meanwhile, during when needs debugging or to circuit board write-in program in enormous quantities, need the outside 24V supply voltage of access in addition, work efficiency is not high, and the running status of circuit cannot obtain effectively real-time monitoring, thus govern development and the raising of whole production technology.

Utility model content:

Technical problem to be solved in the utility model is to provide and a kind ofly can realizes collaborative work between multi-controller and the Programmable Logic Controller that operational flexibility is strong, work efficiency is high, and can the running status of supervisory circuit in real time.

The technical scheme that the utility model adopts is as follows: a kind of Programmable Logic Controller, comprises CPU module, and described CPU module is connected with communication module, function input/output module and power adjustment module; Described communication module comprises serial port module, ethernet communication module, wireless communication module and usb interface module, and described function input/output module is provided with multi-analog input/output port, multi-way switching values input/output port and multiplex pulse amount input/output port;

Described serial port module, ethernet communication module and wireless communication module are used for needing the multiple collaborative Programmable Logic Controller of collaborative work to carry out real-time communication contact with other; When described usb interface module is used at commissioning device and to large batch of Programmable Logic Controller write-in program, provides 5V direct current to Programmable Logic Controller, greatly increase work efficiency, and by the supervisory circuit work in real time of this usb interface module.

Described function input/output module is for inputting extraneous on-the-spot perceptual signal and exporting control signal;

Described CPU module be used for the task that the multiple collaborative Programmable Logic Controller of mutual communication has needed is analyzed and is dispatched, finally reach multiple collaborative Programmable Logic Controller work in coordination with finish the work.

Beneficial effect is: the utility model achieves that multiple Programmable Logic Controller is collaborative finishes the work, the simple application that can complete from separate unit controller can be adapted to, to needing the multiple stage even large complicated application of thousands of controllers collaborative work together, improve production efficiency, and accommodation is wide, integrated level is high; Its communication module is also integrated with usb interface module, for during at commissioning device and to large batch of Programmable Logic Controller write-in program, 5V direct current can be provided to Programmable Logic Controller, greatly increase work efficiency, and by the supervisory circuit work in real time of this usb interface module, client can be facilitated to greatest extent, have very strong dirigibility, thus be convenient to application.

Accompanying drawing illustrates:

Fig. 1 is the utility model structured flowchart.

Embodiment:

A kind of Programmable Logic Controller, comprise CPU module, described CPU module is connected with communication module, function input/output module and power adjustment module; Described communication module comprises serial port module, ethernet communication module, wireless communication module and usb interface module, and described function input/output module is provided with multi-analog input/output port, multi-way switching values input/output port and multiplex pulse amount input/output port;

Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
