Apply your knowledge of Relay Logic Instructions to design a program that 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:  

Transcribed Image Text:

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 1. There is a slight dead band to prevent flickering lights when tank levels vary slightly due to filling or splashing.
