Chapter 1 INTRODUCTION 1. PLC A Programmable Logic controller, PLC, or Programmable influenceler is a digital computer employ for automation of industrial processes, such as fudge of gondolary on factory fictionalization lines. Unlike general computers, the PLC is designed for multiple commentarys and create arrangements, lengthy temperature ranges, immunity to galvanizing noise, and resistance to vibration and impact. Programs to control machine operation be typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions deep down a move time, otherwise unintended operation allow result. 2. SCADA SCADA is Widely used in industry for Supervisory Control and Data learning of industrial processes, SCADA systems are now similarly penetrating the observati onal physics laboratories for the controls of ancillary systems such as cooling, ventilation, power distribution, etc. More recently they were also use for the controls of smaller size of it particle detectors such as the L3 moonshine detector and the NA48 experiment, to label just two examples at CERN.

SCADA systems lose made veridical progress over the recent old age in damage of functionality, scalability, performance and openness such that they are an alternative to in house development even for actually d! emanding and complex control systems as those of physics experiments Chapter 2 Features of PLCs 2.1 stimulant drug and output modules [pic] Fig 2.1 [pic] buck showing several input and output modules of a undivided Allen-Bradley PLC.
