Design Problem: You have just been hired as a Controls Engineer at XYZ Systems Integrator. Your first project is for a client who wishes to retrofit (modernize) an industrial wash unit. The current system utilizes a mechanical drum sequencer type motorized mechanical timing device. Based on what you have learned in TEC 263, you know that a PLC would be a perfect solution to this problem! The customer is willing to replace or "rewire" 1/0 as necessary (e.g. switches, button, sensors, etc.) but, the process must remain the same. Since you decided to use a PLC, you now have the ability to provide a few enhancements! So, the customer also requests that the number of completed wash cycles is tracked and displayed (something that was not being done before). Using the following industrial electrical (wiring/ relay) ladder diagram and the corresponding functionality chart, design a PLC system (ladder logic program and HMI) to satisfy the customer's needs. For testing purpose, use 1 second as the default timer increment based on a cumulative time (e.g. Timer Increment of 2 on the chart would be from 1 to 2 or a 1 second interval) HINT: You will use a timer, counter, and bit-level addressing to solve this problem (and many other concepts we've covered so far!) For this problem, you can ignore the LINE SWITCH, but don't forget to include the SAFETY WATER LEVEL SWITCH (Normally Closed) when operating the fill valve.
