Packaging Industry Essay

ABSTRACT

The aim is to understand the automation process of packaging industry.
Packaging is among the high growth industries in India & developing at the rate of 22-25% per annum & becoming a preferred hub for packaging industry. Packaging industry is completely automated using PLC & SCADA.

Supervisory control & data acquisition is a software application program for controlling of various processes process, the collection of data in real time from remote locations in order to control equipment & condition. A programmable logic controller (PLC) is a digital computer used for automation of typically industrial electromechanical procedure, such as control of machinery on factory assembly lines.

The Printing type done is gravure type. Lamination is done in which a silver sheet of

3.6 Functional Blocks
3.6.1 Analog Block
• The sending or receviing of analog data from opc server or i/p driver is done by analog input block.
• The processing of various other blocks is started by Next block field.
• The analog signal is sent to i/p driver or opc server by analog output blk
3.6.2 Digital Blocks

• the Digital data (one or zero ) is sent by digital iput block from i/o driver
– It is known as primary blk
– it is used often as stand‐alone blk.

3.6.3 Calculation Block - Example

Calculation of this block is to convert a temperature
((A*B) + C)

where A is the input taken from the upstream Analog Input block, B is 67 and C is 09
3.6.4 Boolean Block - (BL)
The Boolean (BL) blk calculates a single true/false output from multiple inputs.
A true or a false value is calculated from multiple inputs by boolean blk
– It is also known as the primary blk.
– it can also be used as stand blk.
– It gives only one output value and can take 8 input values.
– a digital output block give or send a true or a fase value to boolean block
