Timer 3 minutes – (Internal) 3 – Develop a logical sequence of operations: Timer 3 minutes done bit – On/Off (Internal) Stop Pushbutton – Normally Closed – On/Off Start Pushbutton – Normally Open – On/Off What sensors will be used in the PLC program? The start button is pressed to repeat the sequence. The empty sensor switch opens to de-energize solenoid B when the tank is empty. When the agitate motor stops, solenoid B is energized to empty the tank. The mixer motor starts and runs for 3 minutes to mix the liquid. When the tank is complete, the full-level sensor switch closes. As the tank fills, the empty level sensor switch closes. When the start button is pressed, solenoid A energizes to begin filling the tank. 1 – Define the task:Ī normally open start and normally closed stop pushbuttons are used to start and stop the process. We will discuss each step of the PLC program development. The process mixer will be programmed using ladder logic. In addition to the program hardcopy and documentation required the grading rubric, submit your PLC programs via email not later than class time on the due date.We will apply the five steps to PLC Program development to our following programming example of a process mixer.
