CN104715433A - Parameter setting method for PLC (programmable logic controller) communication system in new program slicing technology for E-business website industry - Google Patents

Abstract

The invention discloses a parameter setting method for a PLC (programmable logic controller) communication system in new program slicing technology for an E-business website industry. At an input sampling stage, the PLC sequentially reads all input states and data in a scanning mode, and the states and the data are stored in corresponding units in an I/O image region. After input sampling is over, a user program execution and output refresh stage is turned. At the two stages, even if the input states and the data change, the states and the data of the corresponding units in the I/O image region do not change. Thus, if a pulse signal is inputted, the width of the pulse signal needs to be larger than a scanning cycle, and thus, the input can be ensured to be read in any condition.

Description

The parameter setting method of the plc communication system towards electric business website industry of new-type program slicing technique

The parameter setting method of the plc communication system towards electric business website industry of the new-type program slicing technique of the present invention belongs to the data handling system or the method that are specially adapted for administration, business, finance, management, supervision or predict object; What other classifications did not comprise is specially adapted for administration, business, finance, management, supervision or predicts disposal system or the method field of object.

(sequence) able to programme controller (Programmable Controller), is a kind of small-size computer being used for carrying out robotization and controlling in real time, is mostly used in now the such industrial occasions of mechanization Pipeline control.Before programmable controller occurs, hundreds of relay and gear timer generally will be used could to form the automated system with identical function, and now, the simple programmable controller module through programming instead of the device of these large heads substantially.The system program of programmable controller generally before dispatching from the factory initialization complete, user can meet no automated production requirement according to the needs of oneself from the corresponding user program of edlin.

After programmable logic controller (PLC) puts into operation, its course of work is generally divided into three phases, and programmable logic controller (PLC) and input sample, user program execution and output refresh three phases.Complete above-mentioned three phases and be called a scan period.During whole service, the CPU of programmable logic controller (PLC) repeats above-mentioned three phases with certain sweep velocity.

One, the input sample stage

In the input sample stage, programmable logic controller (PLC) in turn reads in all input states and data with scan mode, and by them stored in the corresponding unit in I/O image area.After input sample terminates, proceed to user program and perform and export the refreshing stage.In these two stages, even if input state and data change, the state of the corresponding units in I/O image area and data also can not change.Therefore, if input is pulse signal, then the width of this pulse signal must be greater than a scan period, and under any circumstance, this input all can be read into guarantee.

Two, the user program execute phase

In the user program execute phase, programmable logic controller (PLC) always in turn scans user program (trapezoidal literary composition) by order from top to bottom.When scanning each trapezoidal literary composition, always first scan again the operation circuit be made up of each contact on the trapezoidal civilian left side, and by first left and then right, first up and then down order, logical operation is carried out to the operation circuit be made up of contact, then according to the result of logical operation, the state of this logic coil corresponding position in system RAM memory block is refreshed; Or refresh the state of this output winding corresponding position in I/O image area; Or determine whether the specific function instruction that will perform this trapezoidal civilian defined.

Namely, in user program implementation, the state of input point in I/O image area and data are only had to change, and state in I/O image area or system RAM memory block of other output points and software and data all likely change, and arrange superincumbent trapezoidal literary composition, its program execution result can work to the every trapezoidal literary composition using these coils or data come below; On the contrary, come trapezoidal literary composition below, the state of the logic coil that it is refreshed or data can only arrive the next scan period and could work to row's program in the above.

If use I/O instruction immediately in the process that program performs, can direct access I/O point.Namely use I/O instruction, the value of input process shadow register can not be updated, and program is directly from I/O module value, and output procedure shadow register can be instantly updated, and this is with inputting some difference immediately.

Three, the refreshing stage is exported

After scanning user program terminates, programmable logic controller (PLC) just enters and exports the refreshing stage.During this period, CPU according to state corresponding in I/O image area and all output latch circuit of Refresh Data, then drives corresponding peripheral hardware through output circuit.At this moment, the real output of programmable logic controller (PLC) is only.

edit this section of functionfeature

Programmable logic controller (PLC) has following salient feature.

1. easy to use, programming is simple

Adopt the programming languages such as simple and clear trapezoidal literary composition, logic literary composition or statement list, and without the need to computer literacy, therefore system development cycle is short, field adjustable is easy.In addition, can online modification program, change control program and do not tear hardware open.

2. function is strong, and the ratio of performance to price is high

There are hundreds and thousands of for the programmed element of user, very strong function can be had in a small PLC, very complicated controlling functions can be realized.It is compared with the relay system of identical function, has the very high ratio of performance to price.PLC by communication networking, can realize decentralised control, centralized management.

3. hardware is comprehensive, and user is easy to use, strong adaptability

The standardization of PLC product, seriation, modularization, be equipped with the various hardware units of great variety of goods to select for user, user can carry out system configuration flexibly and easily, the system of composition difference in functionality, different scales.The installation wiring of PLC is also very convenient, generally connects external cabling with connection terminal.PLC has stronger carrying load ability, can the general solenoid valve of Direct driver and small-sized alternating current contactor.

After hardware configuration is determined, by amendment user program, the change of process conditions can be adapted to quickly and easily.

4. reliability is high, and antijamming capability is strong

Traditional relay control system employs a large amount of auxiliary reclays, the time relay, due to poor contact of contacts, easily breaks down.PLC software replaces a large amount of auxiliary reclays and the time relay, and only remaining relevant with input and output a small amount of hardware element, wiring can reduce to the 1/10-1/100 of relay control system, and the fault caused because of poor contact of contacts greatly reduces.

PLC takes a series of hardware and software interference protection measure, there is very strong antijamming capability, mean free error time reaches more than tens thousand of hours, and can be directly used in the industrial site of strong interference, PLC is known as one of the most reliable industrial control equipment by users.

5. the design of system, installation, debugging work load are few

PLC software function instead of the devices such as auxiliary reclays a large amount of in relay control system, the time relay, counter, and the design of switch board, installation, wiring workload are greatly reduced.

The trapezoidal civilian program of PLC generally adopts Sequential Control Design to design.This programmed method is very regular, is easy to grasp.For the control system of complexity, the time designing trapezoidal literary composition wants much less than the time of the relay system circuit literary composition of design identical function.

The user program of PLC can be debugged in laboratory simulation, and input signal P cock is simulated, by the state of the light emitting diode observable output signal on PLC.After the installation completing system and wiring, the problem found in tuning process at the scene generally just can be solved by update routine, and the debug time of system is than relay system much less.

6. maintenance load is little, easy to maintenance

The failure rate of PLC is very low, and has perfect self diagnosis and Presentation Function.When the input media of PLC or outside and topworks break down, the information that can provide according to the light emitting diode on PLC or programmable device promptly finds out the reason of fault, promptly can get rid of event by the method changing module

Initial programmable controller only has the function of logic control, so be named as (sequence) able to programme logic controller (Programmable Logic Controller, PLC), afterwards along with continuous development, these originally the simple computer module of function had and comprised logic control, sequential control, analogue enlargement, the function that multi-computer communication etc. are many, title also changes Programmable Logic Controller (Programmable Controller) into, but because writing a Chinese character in simplified form of it is also that PC conflicts mutually with writing a Chinese character in simplified form of PC (Personal Computer), also due to use habit for many years, people or often this address of use programmable logic controller (PLC), and in term, still continue to use this abbreviation of PLC.

Whole project adopts loop iteration development mode, and every a line representative once circulates, namely from core algorithm until Website development.An iteration is shown in each list, i.e. an iteration of whole platform.This development mode can better meet the demand of platform operation.

Be divided into by the application of platform:

1, B2C platform

Although data show, the flow speedup of 2013 will slow down, and still not keep out the sustainable development of B2C.B2C platform remains the first object that online spending platform is selected by a lot of enterprise, sky cat, Jingdone district, a shop ... when fully funded, the platform generally can moved into all can not be abandoned, and entrance audients different is after all different, and userbase is primary.

2, independent store

Independent store is exactly rely on mall system to make independent on-line shop containing TLD.The benefit opening independent on-line shop no more than: TLD, Own Brand, corporate image, cost-saving, autonomous management, unfettered.

3, C2C platform

C2C several years ago very popular, but is not equal to before to 2013 annual trends.Individual, can attempt Taobao, pat, enterprise had better not plow this time muddy water.After it cat is independent, gap is just pulled open gradually, and splendidness continues by B2C.

4, CPS platform

The CPS platform of main flow containing neck cut, hundred million send out, be current electric business compared with one of the way of promotion of main flow, expense is promoted by CPS pattern the valid order produced and is carried out ratio and be divided into.The very large reason that CPS pattern becomes main flow Extension Model is free from risk exactly, and throw advertisement and probably spent large price and caused very low conversion ratio, bid, through train may not produce order, but CPS creates sales volume just to have commission, ROI is higher.

5, O2O platform

Current O2O platform mainly refers to and purchases by group platform, handle net, popular comment, Gao Peng, F group etc., due to its high performance-price ratio, is still subject to a lot of user favor.Certainly, we do not get rid of other more O2O network selling platform and patterns, expect that 2013 have and new pleasantly surprisedly bring us.

6, online shopping mall of bank

At the initial stage, the object that many banks offer online shopping mall sets up to use the user of credit card to pay by instalments.Along with ecommerce is universal, user's request enhancing, technological means promote, and online shopping mall of bank also progressively grows up.On-line shop of bank provides all-around service for user, comprises that integration is purchased on a barter basis, monthly payment plan etc., also covers payment, financing, guarantee etc., is the most significantly to provide displaying, the platform of sell goods and chance to a lot of businessman.If this platform operation is good, in the future with high achievement.

7, operator's platform

China Mobile, CHINAUNICOM, China Telecom, present stage respectively runs commercial city one's own store platform.Due to the hard requirement of communication service, the user of operator's platform has certain dependence and viscosity all the time, so seize these platforms in advance there is very large strategic importance, and this reason just of riding on a horse to enclose.

Application example example one

PHILIPS light source division department requires that each retail trader sets up unified lump-sum purchase plan, finance, the operating information system of each retail trader of specification, and from management level, the operation result of every aspect examination retail trader, to keep operation result and the corporate image of main office.

PHILIPS light source division department employs UFSOFT ERP/U8 Network Distribution system, by adopting Internet technology, fundamentally solves the distribution of enterprise cross-region distribution UFSOFT ERP/U8 Network Distribution system

And the cross regional business brought works in coordination with the difficult problem with management and monitoring.UFSOFT ERP/U8 Network Distribution system is the database application (technical characterstic) of a complete sing on web, it not a simple page, but complicated business logic can be processed, the application program of powerful management and powerful data analysis, mining ability, and all advantages having that legacy application uses.

The sale management system of PHILIPS company includes the financial system modules such as general ledger, receivables and payables, UFO table, includes again the purchase and sale such as purchasing management, stock control, inventory auditing and sales management and deposits operation system module.By secondary development, sale management system adds the plug-in module of software based on reporting system, and this reporting system mainly comprises supply chain management module and receivables administration module.
