PLC

Design a circuit based on the description and specifications below: This circuit will sequence through four separate subroutines (Label Call Functions), each for a specified period of time. The sequence must be able to be started and stopped by a single command with an override for each subroutine if needed. The sequential operation will be automated so that once started it will step through each subroutine as designed and cease functioning when complete. - Pressing and releasing the Process Start (Input) begins the automated sequence - Once started subroutine zero will be active for 5 seconds - After subroutine zero is finished, subroutine zero becomes inactive and subroutine one becomes active for 5 seconds - After subroutine one is finished, subroutine one becomes inactive and subroutine two becomes active for 3 seconds - After subroutine two is finished, subroutine three becomes ative for 2 seconds - After subroutine three is finished the circuit stops, resets and is ready to begin again - At any time during the process pressing and releasing Process Stop (input) will stop the circuit from functioning - Each subroutine shall have a manual override, that when active will keep that singe subroutine active - The circuit will utilize one timer as a master to time the subroutine sequence - The circuit will utilize a second timer as a master to time the functions residing inside each subroutine - The four subroutines will function as follows: SBR 0 will activate 5 outputs to count up from 1.5 and repeat, each output should be active for 0.5 seconds SBR 1 will activate 5 outputs to count down from 51 and repeat, each output should be active for 0.5 seconds SBR 2 will incrementally add 1 each time the subroutine is active SBR 3 will add 5 each time the subroutine is active Your report must include the following items: - Calculated theoretical scan time for at least one selected subroutine - Measured scan time for at least one selected subroutine - Calculated theoretical memory usage for the entire program - Actual memory usage for the entire program - Compare the differences in the theoretical calculated and the measured values
