Design and Development of PLC Based Chemical Mixing Plant

This paper introduces an efficient solution for integrating a Programmable Logic Controller (PLC) into chemical industry processes, emphasizing precise mixing of three solutions. Leveraging conventional PLC components and ladder logic, the project employs digital inputs through push buttons to control relay-based outputs. Accurate filling ratios are achieved using a combination of time-based sequencing and user input. Code transmission challenges are addressed with a data integrity buffer and CH 340 drivers. Timing control utilizes the PLC's onboard timer (TON), while open PLC software and Atmel microcontroller libraries ensure smooth operation. This concise project offers a streamlined approach for PLC integration, optimizing chemical industry applications
