Description

A kind of PLC controller application apparatus based on bus form

Technical field

The utility model relates to a kind of controller, relates in particular to a kind of PLC controller application apparatus based on bus form.

Background technology

The PLC controller, it adopts a class programmable memory, be used for its internally stored program, actuating logic computing, sequential control, regularly, user oriented instructions such as counting and arithmetical operation, and control various types of machineries or production run by numeral or analog I/O.

The PLC controller is applied on the various plant equipment, before production, programme, machine operates automatically by the data of programming, and iron plate processing is complete in manually finishing before this, the reliability that this mode is processed iron plate is low, production efficiency is low, working strength is big, defect rate is very high, degree of accuracy is unsatisfactory especially, therefore it is extremely urgent, imperative this kind mode of production to be carried out automatic improving.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of degree of accuracy height, production efficiency height, produces PLC controller more easily.

For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of PLC controller application apparatus based on bus form, described controller comprises the casing housing and is installed in the interior central processing unit of casing housing, be connected with system program storer, user program memory, power module, load module, output module on the described central processing unit, on the central processing unit external-connected port, be connected with programmable device, touch-screen in turn.

Three ports on the described load module connect pushbutton switch, relay contact, travel switch respectively.

Three ports of described output module are connected with contactor, signal lamp, solenoid valve respectively.

The utility model has the advantages that: PLC controller good stability, adopt the touch screen operation input, convenient directly perceived, dirigibility is better, makes that the product processed precision is higher, thereby has improved yield rate, has reduced labour's use, saves financial cost.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model PLC controller architecture block diagram.

Embodiment

As shown in Figure 1, a kind of PLC controller application apparatus based on bus form, described controller comprises casing housing 1 and is installed in central processing unit 11 in the casing housing 1, be connected with system program storer 12, user program memory 13, power module 14, load module 15, output module 16 on the described central processing unit 11, on central processing unit 11 external-connected ports, be connected with programmable device 2, touch-screen 3 in turn.Three ports on the described load module 15 connect pushbutton switch 4, relay contact 5, travel switch 6 respectively.16 3 ports of described output module are connected with contactor 7, signal lamp 8, solenoid valve 9 respectively.

Central processing unit 11 plays a part the commander in chief as the core of whole PLC, generally is made up of control circuit, arithmetical unit and register.These circuit generally are encapsulated on the integrated circuit (IC) chip.Central processing unit 11 is connected with system program storer 12, user program memory 13, load module 15, output module 16 interface circuits with control bus by address bus, data bus.

Load module 15, output module 16 interface circuits are parts that the PLC controller is connected with on-the-spot controlled device or other peripherals, and it plays a part the information of transmitting between PLC and the peripherals.The various control signals of subscriber equipment input PLC controller, as input signals such as the switching value of pushbutton switch 4, relay contact 5, travel switch 6 and the output of some other sensor or analog quantitys, the signal that becomes central processing unit 11 to accept and to handle these conversion of signals by input interface circuit.

The above only is a preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
