PURPOSE

Refer to this guide for help understanding and using the VNC Controller Viewer for the Tunnel Controller. You can use VNC Viewer to:

  • View tunnel function/application statuses in real time
  • Manually activate and deactivate tunnel functions/applications
  • See the tunnel speed and average car length updated in real time
  • Perform other tunnel functions (e.g., simulate a pulse, clear cars from the queue)

NOTE: Do NOT leave VNC Controller Viewer open and unattended! Accidentally pressing the keyboard could disable a tunnel function/application.


PROCESS

Overview



VNC Viewer Interface

  1. Tunnel Activity is at the top of the screen and displays important information about the tunnel activity:
    • IP - The IP Address of the connected Tunnel Controller PC.
    • Entry Sensor – this field reads EMPTY when there is no car in the eye. It changes to read MEASURING when a car is passing through the eye.
    • Input Board – the communication status between the Tunnel Controller and the Relay Station Input Board.
    • Local Time – The time the Tunnel Controller thinks it is
      • NOTE: This time is important to remember when trying to locate information in the logs.
    • App Time – The total time that the Tunnel Controller has run since the last restart.
    • Speed – conveyor speed provides two options and these calculations are updated in real time:
      • CPH (Cars per Hour) - The estimated number of Cars Per Hour that the track could support at the current speed.
      • FPM (Feet per Minute) - The number of Feet Per Minute that the controller thinks the track is moving.
    • Ver - The current running Tunnel Controller software version.
    • Avg Car Length – The average of the measured length (photo eye) of all vehicles this calculation is updated in real time. This is used to calculate the CPH.
    • Pulse/No Pulse – When the conveyor is running, this value should change to PULSE, indicating we are receiving information from the conveyor on its movement..
    • Orders – this is the number of vehicles currently in the queue (it will match the number of tickets shown in the Queue section directly below)
  2. Inputs on the left middle section displays a list of tunnel inputs and their statuses (ON and OFF) updated in real time.
    • The list of inputs is always visible in the Controller Viewer interface.
    • Not all the inputs in the list will be connected or configured. The most important ones are:
      • Conveyor – A signal from the start stop board indicating we have requested that the conveyor start.  Conveyor will continuously read ON when the conveyor is turned on.
      • Entry Sensor – Photo Eye devices that measure the overall length of the vehicle.
      • Tire Sensor– A floor mounted sensor that detects where the vehicles tires are.
  3. Outputs on the middle middle section displays a numbered list of all tunnel functions/applications and their statuses (ON and OFF) updated in real time.
    • Highlight functions/applications using the arrow keys.
    • The output list can only display 32 relays at a time. Use the keyboard arrow keys to navigate through the output list, up to relay 128. The selected output will be highlighted blue as shown above.
      • By default, functions/applications are set to automatically turn on and off according to tunnel programming. Use the keyboard Space Bar to force devices on or off. 
        • No Icon – The device is set to Auto.  The device will turn on and off based on programming.
        • + Icon – The device is forced on. The system will keep the relay in the On position.
        • – Icon – The device is forced off. The system will keep the relay in the Off position.
    • Feedback – As devices turn on or off through programming or from using the space bar as described above, the output list will display their status. This can be used to verify the communication status of the output boards. 

  4. Queue on the right middle section displays information about vehicles currently in the queue.
    • The queue list displays all the wash services currently in the tunnel.
      • Order Number – The number on the left of the list indicates what order number is attached to the wash. This number is helpful if searching the log files.
      • Line & Arrow Color – Indicates that the vehicle is currently being measured by the photo eyes (Entry Switch).
        • No icon indicates the car has not yet reached the eye.
        • Green Arrow Line (–>) means the eye determined the car is long enough to proceed through the tunnel.
        • Green Line (–) means the car has passed the eye.
        • Red Arrow Line (–>) means the eye determined the car is too short (minimum length is 4’ and maximum length is 35’).
        • Red Line (–) means the car is stopped at the eye or is out of order.
      • Service Numbers– The services being applied to the vehicle, separated by commas. The numbers relate to the services programmed into the controller.
        • 21 – Base Wash
        • 22 – Base Plus Wash
        • 23 – Platinum Wash
        • 24 – Titanium Wash
        • 12 – Full Retract
        • 17 – Top Brush Retract
        • 25 – Mud Flush
        • 30 – Wet Down
        • 31 – Dry Check
        • 40 – Tire Shine Retract
        • 41 – Open Bed
        • 42 – Bike Retract
        • 43 – Roof Retract
        • 44 – Trailer Retract
        • 45 – Low Profile
        • 46 – Grill Guard
        • 47 - Convertible
  5.  Keyboard Controls - The bottom of the VNC image displays available keyboard commands.
    • Output list quick access buttons – each number key changes the displayed outputs in groups of 32.
      • 1 - Outputs 1-32
      • 2 - Outputs 33-64
      • 3 - Outputs 65-96
      • 4 - Outputs 97-128
    • T – Toggle Simulated pulse
      • Changing from live pulse to simulated pulse is useful when troubleshooting a pulse related issue.
      • The system will automatically switch to simulated pulse when it detects abnormal pulse inputs.
    • C – Clear
      • Clears the queue of all vehicles.
    • R – Reload
      • Reloads the controller software.
      • Clears the Queue of all vehicles.
    • X – Exit
      • Forces the controller PC to shut down the software completely and reload the software.
      • Clears the Queue of all vehicles.
