Simulation of Level Control on Rainwater Collection Pumps Based on MikroWin Software Step7

In today's modern era, which is very advanced, automation systems are vital to increase efficiency in industry and make it easier for operators to control machines or tools. Programmable Logic Controller (PLC) is a control system that is widely used in industry. Machines or tools in the industry that were initially controlled manually can be controlled automatically by PLC. PLC can work as needed by programming it via PC. The programming language used to program the PLC is a ladder diagram. This simulation aims to understand how the PLC works on the pump level control in the rainwater reservoir. For the programming process using Step7 MicroWin. The program that has been made is simulated through the S7-200 Simulator. For HMI can be displayed with PC Simu. This simulation uses 3 pumps controlled by PLC. Creating a simulation of pump level control in a rainwater reservoir requires a ladder diagram. The address on the symbol, comments from the symbol, and address must be correct, must be by the initial plan to the end, and the simulation is ready to be tested. In general, in the industry, there is disposal or storage of rainwater. Water is channelled through existing channels or drainage in the industry to the rainwater reservoirs. After the rainwater reservoir, the water will be channelled to the WWTP (Wastewater Treatment Plant). The three pumps function to suck or suck the water in the rainwater reservoir to the WWTP. The pump runs when it reaches the setpoint specified in the program. The pump will stop if it is below the setpoint specified in the program. Each pump is set to a predetermined dead band.
