PLC-PROGRAMMABLE LOGIC CONTROLLER,used for
automation...earlier we used hard wire logic control and
then logic gates..PLC s the advance system inwhich we can
program the fuction what s to be carried out. Main
advantages of PLC:
1.Less number of wiring
2.process can be modified anytime by programming online
without disturbing any ongoing process.
3.Fault identification s very very easy which in turn
machine breakdown time will come down. Ultimately increase
in production.
4.Easily can be linked with any operating panels like HMI
to communicate with other process related systems..
PLC has Input module,O/P module and a processor. The field
inputs like a switch,sensors will be connected to Input
modules whereas field outputs like motor
starter,relays,valves etc. will be connected to Output
module. The program for assigned function will be stored in
processor with help of programming software given by PLC
manufacturers. For basic knowledge about PLC pls visit
PLCS.NET website.
