| Summary: | The project aim was to a built an electronic board which detect signal from
Omron PLC trainer. A programmable logic controller (PLC) in an operating system
such as a machine includes a software development. The hardware part was based on
a simple circuit on Printed Circuit Board (PCB) with LCD display. The signals from
programmable logic circuit were transferred to PCB board as a time clock signal.
PIC 16F877A microcontroller was used as interface in order to display time clock on
LCD display. The electronic board also was designed with the voltage regulator to
step down the voltage, 24V form PLC to 5V. The software development started with
the flow chart, ladder diagram for PLC and finally, the software was written in C
language and implement on the PIC. As the result, whenever the PLC counting and
change the signal (clock), the LCD display will shown the output simultaneously
with the PLC. |
