This document describes an automated car wash system designed and simulated using RSLogics 5000 PLC software. The system was divided into two zones - zone 1 for presoak, foam application, and scrubbing, and zone 2 for rinsing, waxing, and drying. Cars arrive randomly and the program can speed up operations if there is a long queue. Zone 1 performs its operations then waits for zone 2 to indicate it is ready before moving the car. Once operations in both zones are complete, the car is moved out and the number of cars washed is displayed. Challenges included understanding program scan order and adding structured text for zone 2 operations. Ladder logic diagrams show the logic for zone 1 and 2 operations

1. AUTOMATED CAR WASH
BY- Koyya Shiva Karthik Reddy
Dept. Of Electrical and Microelectronics
Rochester Institute of Technology
INRTODUCTION
As a part of the course requirement an automated car wash system was designed On RSLOGICS
5000 taking into consideration scenarios which were close enough to real world car wash
system. The entire system was divided into two zones namely zone 1 which included
operations pre-soak, foam applicator and scrubbing and zone two had operations rinsing, wax
applicator and drying, both the zone were implemented on two different controllers which
communicated via Ethernet . The program was designed such that it can handle cars arriving at
random interval and can also speed up the process of all operations in both the zones if the
waiting queue was long. Most of the logics were written in ladder digrams.
INPUT AND OUTPUTS USE TO SIMULATE THE OPERATIONS IN ZONES
OUTPUTS Type Zone1 use Zone2 use
Cylinder Entrance door Exit door
Light Pre-soak operation Wax applicator
Dc motor Scrubbing operation Rinse
Fan Foam applicator Dryer
Stepper motor Car mover Car mover
DISPLAY BCD display Cars in queue waiting Cars washed
INPUTS Selector switch System start
Cylinder sensors Indicators Indicators
UDT: UDT was made to transfer data between the zones (produced and consumed tags)
 ZONE1_STATUS BOOL
 SYSTEM_STATUS BOOL
 MODE DINT (1 OR 2)

2. AOI: A random number generator was used to generate cars at random interval
Structured text: “Seq_operation” in zone 2
ZONE 1 FLOW
Once the system was started cars were generated at random intervals and the numbers of cars
in the queue were checked to determine the mode of operation (mode 1 or mode 2 indicating
normal or fast operation respectively) once the mode was decided the cars was taken in and
the sequence of operations were performed and once all the operations in zone 1 were over
zone1 waited for a indicator from zone 2 saying its ready before moving cars to zone2.
ZONE 2 FLOW
Once the car was moved to zone to it would carry out sequence of operations based on the
mode received from zone 1 , and once the operations of zone 1 are over it moves the car out of
the car wash and indicates it ready to except new car in into the zone.

4. CHALLENGES
The project was basically simple but the main problem I faced was to understand how the scan
in the program goes on, when there is a control shift from main to subroutine and as a result of
this problem I wasn’t able to use my AOI which was random car generator as I wanted it to be
scanned only once every program but it used to be scanned continues and kept adding cars.
LADDER LOGIC DIGRAMS
Structed text zone 2 sequential operation couldn’t be added with rest of the rungs
