Computer Based PLC with Application
Abstract
Controlling appliances from our PC is quite interesting and
convenient. In this project the simple circuit along with the software is used
to interface the PC with the Electronic circuit.
The Gates(And, Or, Not etc) and the Input variables are set
in the system. The corresponding signal is transmitted through parallel port
and the PLC kit receives the signal.
The High or Low Input are set in the PLC kit by using
switches. The control operations are done in the Microcontroller using
PLC(Ladder Logic) Programming.
The output is derived in the PLC kit. By using the output
one can control any machine. In industries, because of some extraordinary problems like
over heating, vibration etc, the motor may be burnt.
By using ladder logic program and proper sensors, we can
identify the problem and immediately the motor can be stopped to prevent
burning. Computer Based PLC with Application project uses Visual
Basic as designing language and Assembly language as Microcontroller language.
PIC16F73 is used as Microcontroller
