In this exercise we want you to apply your knowledge of Relay Logic Instructions to design a program which will Monitor and Control the filling of a tank. The program you create will monitor and control this equipment while adhering to the following criteria The PLC program simulates a process tank being filled with a fluid. The tank will start filling (via a valve) whenever the start process button is enabled and the tank is below 50% full. It will shut off when the tank is 100% full. In case the level sensor is out of calibration or not working properly, there is a high-level safety limit to prevent the tank from overfilling. If the high limit is met at a preset value of 102% full the process will shut down and a strobe light will turn on Indicator lights are activated when the tank level reaches 50%, 75% and 100% full as shown in the diagram of the tank in Figure I. 2/5 Ultra Son Level Sensar High Le Sensor lenkerang Strebe Tank High Link Strand In Process 100% Low Level Rulam Silence Start o 50% Stop o Figure 1. Diagram of the tank There is a slight dead band to prevent flickering lights when tank levels vary slightly due to filling or splashing If the tank for some reason does not fill up to a minimum level of 50% within 5 minutes after the valve energizes, an alarm will notify an operator. The operator will be able to silence the alarm for 5 minutes by pressing a silence button. After five minutes the alarm will trigger notifying the operator once again. The operator will be able to silence the alarm two times. If the silence button is pressed a third time, the alarm will remain on and an energized strobe light will notify anyone within the site of the tank. The silence button will be tampered proof by utilizing a one-shot rising instruction to prevent an operator from holding the button in If the tank remains under 50% full, the only way to de-energize the alarm and strobe is to stop the process
