THE MODULAR PLC PROGRAMMING

PRESENT:

INTRODUCTION

Machines simple or complex are made by actuators, motors, cylinders... and the assembling of all these equipments make a machine.

HOW MACHINE OPERATE

Normally machine are made by assembling of several parts in a logic process and all the movements are controlled by plc (Programmable Logic Controller) which is responsible of all automation movement in the machine

WHAT IS PLC

A Programmable Logic Controller, or PLC, is more or less a small computer with a built-in operating system (OS). This OS is highly specialized to handle incoming events in real time, i.e. at the time of their occurrence.

AUTOMATION

An automaton or sequential machine is a discrete and usually finite system that proceeds sequentially from an initial state to a final discrete state upon changing its inputs, and that also produces an output at each step determined by the input and the internal state of the automaton. An automaton thus defined has a state space which is a finite semigroup or monoid, and that can be decomposed into certain types of modules or parts in a canonical manner. Two functions or maps usually determine mathematically the functioning of the automaton: the transition function from one state to the next, and the output function that maps an input and a specific state to a specific output of the automaton.

MISSION

Our target is divide all kind of machines in multiblocks which can be programmed in user friendly way without having programming knowledge with result of reducing installation and maintenance cost.

The standardization of processes will enable to select parts of plant and put them in the sequence of machine like composition

APPLICATION

Our system can be used in all automatized machine and based on the customers requirement we can apply the software blocks easily programmable by installator by using the Hmi present in machine

What is Hmi

A human–machine interface or HMI is the apparatus which presents process data to a human operator, and through which the human operator controls the process.

COMPATIBILITY

Our system run based on IEC 61131-3 which is the programming standard system for Plcs and this guarantee the interchange with different suppliers of Plcs.

IEC 61131-3

IEC 61131-3 is the third part (of 8) of the open international standard IEC 61131 for programmable logic controllers, and was first published in December 1993 by the IEC. The current (second) edition was published in 2003.

Part 3 of IEC 61131 deals with programming languages and defines two graphical and two textual PLC programming language standards:

• Ladder diagram (LD), graphical • Function block diagram (FBD), graphical • Structured text (ST), textual • Instruction list (IL), textual • Sequential function chart (SFC), has elements to

organize programs for sequential and parallel control processing.

IEC STANDARD ADVANTAGES

Advantages for suppliers of production units (machines) Provides more independence towards suppliers at

control level Provides basis for re use of software across platforms Higher flexibility in personnel: not limited to one system

only Less training required Higher efficiency in coding High level of re-usability reduces costs and increases

confidence in planning Provides tools to specify requirements at higher level Better comparison between different offers, esp.

software development Provides link to existing personnel Usable world wide, over and over again Provides a standard communication tool between

engineers at different locations

MACHINES CONTROL LEVELS

All machines are divided in level of controls:1. LEVEL 0; this is Plc which normally is placed near the

machine and control all machine movements2. LEVEL 1; this is Hmi which normally is placed on main

console where operator stay because in this all information regarding operation and alarms are displayed

3. LEVEL 2: this is Scada which normally is placed in a separate room where only production responsible are checking it and where all information regarding machine are stored and saved.

4. LEVEL 3: this is Cim which is normally placed in the main office and from this all information regarding production of all machines are checked, stored and organized

Our Intelliproj system work in level 0 and 1, but in we can provide to control the levels 2 and 3 with our Alberi System.

LEVEL 2: SCADA

HMI is usually linked to the SCADA system's databases and software programs, to provide trending, diagnostic data, and management information such as scheduled maintenance procedures, logistic information, detailed schematics for a particular sensor or machine, and expert-system troubleshooting guides.

SCADA (supervisory control and data acquisition) is a type of industrial control system (ICS). Industrial control systems are computer controlled systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large scale processes that can include multiple sites, and large distances.

LEVEL 3: CIM

CIM is "computer-integrated manufacturing" and is a method of manufacturing and the name of a computer-automated system in which individual engineering, production, marketing, and support functions of a manufacturing enterprise are organized. In a CIM system functional areas such as design, analysis, planning, purchasing, cost accounting, inventory control, and distribution are linked through the computer with factory floor functions such as materials handling and management, providing direct control and monitoring of all the operations.

ALBERI SYSTEM

This is the system which is caring about Scada and Cim levels and it is directly connected to the level 0 where are all Plc, with level 1 where are all Hmi, level 2 where are Scada and Production pc and level 3 where is main Pc with all information regarding all machines production and information.

CONCLUSIONS

We surely can say that none in automation market give what we propose, so we can say this is a revolution in programming system and we are waiting for give our best offer to everyone want make standardization in plc programming and optimation of costs.
