SUMMARY CONTENT OF SUBJECT

APPLICATION OF SIEMENS S7 IN AUTOMATION MANUFACTURE

Teacher guide : NGUYEN MANH HATeacher recension : LAM TANG DUCStudent realize: TRAN QUOC TOAN

Today, in the period of industrialize,

modernize in the country then automation problem, automatic control problem have a important role in manufacture and decide many others development.

With a role who is a student in last year of automatic manufacture branch then I

choose companies with automatic system

to serve for my subject.

I have got guide with all myteacher's heart and both company's carde, I choose two

companies This is HaiVan cement

company and Larger beer company.

Hai Van cement company have a real

difficult, this is :

* Company want to raise automation

standard of Roto-packer group from PLC S5 become PLC S7

* Look for a way to manager number of

cement bag ouput

And to investigate ability of PLC S7-300, I visited Larger beer company and:

* Re-Program for conveyor belt system of Larger beer 's company by S7-300.

My subject consist of 5 chapter and make a

study of matters :

* Introduce general about two company where

I practice

* Organization, civil of company

* Character manufacture, product of

company

* Introduce Process manufacture

* Equipments, machine group in sphere that I

do subject

* Electric equipments

* Management idea for number of bag

coming-out

* Operation priciple of Roto-packer and

conveyor system of pour - house

* Introduce about Siemens S7-200, S7-300

* Program for Roto-packer by S7-200

* Program for conveyor system by S7-300

Chapter 1: Introduce comprihensive

about HaiVan cement Company

Consist of :

* Introduce about company, reason of be born, achiement

* Organization diagram of company

* Introduce obout organization of company,

consist of: diretor, deputy director of businiss, deputy diretor of technical, store-keeper,

* Manage deirect all activity manufacture

* Represent for company in transaction,

report,

* Supervise, conduct and bear duty in front

compant about all operate of company

Deputy director for business:

Assisting, helping director and staff in activity

of administration, labour, salary, civil,

transaction

Deputy director for technology:

* Guide and shadow, impel carde, worker

austere technology process

* Shadow quality after repair Put forward

steps safe for labour

Chater 2: Introduce about manufacture process cement

There, input of company is clinker,

plaster, add Output of company is

cement loose and cement packing

Control manufacture process cement

packer by two way:

- Operate local.

- Control from central.

Property manufacture:

Process manufacture cement was assigned

2 stage :

Stage 1: Concoct clinker from mainly

materials are : chaik, argil, slaggy,

rock-crytal

Stage 2: Clinker become mainly materials

and was grinded with 2 supporting materials are : gypsum and add

Stage 1 : give up materials:

Motorvan carry Clinker pour silo hold

clinker , where was arranged lowed floor, after was behave by conveyor 1 to

ground-pour in swipe was rained by swipe ground-pour on conveyor 2, thin coveyor behave clinker to pour silo clinker

Stage 2: Give up gypsum and add:

Gypsum and add was behaved on catch

of conveyor but adopt other cycles, don’t immigle

Taking gypsum and add dow mainly conveyor was aperated by way:

Pour dired dow 2 show catch conveyor before pour dow mainly conveyor to adapt bucket of gypsum andadd, they adapt speed of 2 short catch conveyor

There is a filter spillage atop of 2 silo

Gypsum only was poured in gypsum silo, add only was poured in add silo by a

valve 2 positions derection atop 2 silo to monitor bucket of materials pour in silo then quantitative weight was put at

Stage 3: Grind materials

become cements

Materials adopt mainly conveyor pour in

grind machine, commision of grind-machine

in mixing and grind, materials become the

farina This compoud after out of

grind-machine will pass broken system The first, a part of compound was sucked by statical

broken system under low pressure, residual part was put on high and poured in dynamic broken system

Stage 4: Coming-out cements

Cements from 2 silo can bring to separate cement out equipments or to 2 roto-packer system Separate

coming-cement was coming-out by vehicle which have air_tight box put under separate cement coming-out equipments

However, company usually coming-out cement which was packed by 2 roto-packer system.

After cements were packet and re-check weigh, they will

follow conveyor to where coming-out, there from they were behaved to consumers.

Introduce about PLC:

PLC is a programmable controller equipment

allow realize flexible logic controller algorism

enact 1 program language.

Forte:

* Eesy program, easy study.

* Easy to chage control program.

* Shortly.

* Easy maintain, repair.

* Capacity of memory is large to contain compex programs.

* To confide in industrial enviroment, hardware was standardized.

* Can communication with other intelligent

equipment such as: computer, connect, expand module.

* Can orientate in fiendish enviroment.

Structure, action principle of PLC:

Structure:

All PLC have main compenents are:

*1 program memory are inside

*1 microprocessor have communication com use for fish with PLC

* I/O module

PLC

program

Output signal Input signal

Programmable logic controller

Besides, a perfed PLC carry 1 program unit by hand or

by computer

Supporting function:

* Preservative memory have function

asprevervative relay, too, mean preserve

signal when power-cut and power was

reprovided then memory com back previous state

* The timers of PLC have function as timer - relay

* Counters

* Arthmentical function

Function and application of PLC:

Congregete signals and return from

Application ability diagram:

Action of PLC:

* Unit central field

Translate Input signals andrealize control activities adopt programthat was saved in memory of CPU, transmit decisions under activities signals form to input equipmens

Use to saved program and can modify or

delete the content ever

Small PLC can content from 300-1000 words.Large PLC can content from 2000-16000

words

I/O : Signals from sensors or content were

connected in input modules of PLC, excitive organisms were connected to input modules

The Process program:

When 1 the program load in memory of PLC, commisions will save in individually address area in memory PLC have counters to count address in mocroprocessor, the program

was realized with gradual by

microprocessor, from top to terminal of the program

Whenver realize the program from top to

terminal call 1 cycle

1 cycle consist of 3 stages:

The first, microprocessor read state of all

input Part of the program which serve for

this work ready in PLC and was called is

Realize the program of PLC:

PLC realize the program by unending cycle Every unending cycle was call scan cycle

Introduce about CPU- 214 :

* CPU-214 consist of 14 inputs and 10 out , have ability add 7 expand modules

* 2048 single words belong to read/write

memory non-voltalite to save the program

* 2048 single words belong to read/rite type

to save data Therein, it has 512 type words belong non-valtalite area

* Total max inputs/outputs are 64 inputs/ 64 outputs.

* 128 Timers assign 3 ranks depend other

* 688 special memories bits are use for

announce states and set regime work

* Interrupt process regime

* 3 high speed counter

* 2 analog adapter

* All memoies don’t lost data between 190

hours since PLC was lost power electrice.

The structure of program

The Program of S7-200 have to have

structue consist of : the main program,

next , the subroutine program and

interrupt program.

* The main program was dinished bu

commision ( MEND )

* The sudroutine is a part of the program, and it was written commision ( MEND), too

* The interrupt program is a part of the

program and it was written commision

( MEND), too

* The program was grouped to become a

grouping behind the main program Next, is interrupt program.

Main program MEND

Main Program

MEND

SBRO The subroutine 1

RET

Realize 1 cycle

Realize main program call

Realize when have interrupt signal

The basic program arithmetic:

I : physical input connect direct get in PLC

Q : physical output connect direct from PLC

T : use to difine timer element in PLC

C : use to difine counter element in PLC

M & S : flag

Chapter 4: Desired Roto-Packer

and Program

Roto-packer group is a almost perfect

automatic system with errand pour out the cement in bag by weigh was prescried,

toss bag to correct position Roto-packer of company is 6RS type Not perfect part of

this group is stage that get bag in

Roto-packer.
