Why Doesn't My Car Park System's Red Light Turn On at the Fifth Car?

Click For Summary
SUMMARY

The discussion centers on a car park system designed to activate a red light when the fifth car enters, indicating that the parking is full. The user reports that the red light only activates when a sixth car enters, despite setting the counter to 5. The control system is programmed using Omron CX-Programmer, which is essential for troubleshooting the logic behind the light activation.

PREREQUISITES
  • Understanding of control systems and logic programming
  • Familiarity with Omron CX-Programmer software
  • Basic knowledge of programming concepts related to counters
  • Experience with hardware interfacing for notification systems
NEXT STEPS
  • Review Omron CX-Programmer documentation for counter configurations
  • Learn about logic gates and their application in control systems
  • Investigate troubleshooting techniques for sensor-based systems
  • Explore examples of similar parking system implementations
USEFUL FOR

Control system engineers, programming students, and anyone involved in designing or troubleshooting automated parking systems will benefit from this discussion.

Homework Statement


A car park has 5 parking slots. When the fifth car enter the car park, a red light notification will turn on indicate the car park is full.
When the car park cars decrease from 5 to 4, the red light is distinguished.

Homework Equations


The Attempt at a Solution


I set the counter to 5, but it's not working.
The lamp will only turn on when there is the sixth car entered.
Help guys! Please refer to the attached picture

Welcome to the PF.

What kind of programming language/simulator is that? I don't know if others are familiar with it, but I'm having trouble deciphering what is going on...
 
This is my control system assignment.
I'm using Omron CX-Programmer
Do you understand my questions?
Thanks for the reply ya:)
