How to check the connection with my ACE PLC, my PC and vBuilder ?

If…

  • The ACE PLC is not see with vBuilder or Windows
  • No USB sign bottom right-hand corner of your vBuilder screen
  • In Setup Hardware, the button  doesn’t work.

Check…

  • if you see the COM port in vBuilder with this tool:
  • In your Windows device manager (devmgmt.msc) if you see VelocioComm

If not, try this :

  • Plug and unplug USB cable, and have a look to the Device Manager Windows.
  • If the list refreshes as you plug it in/unplug it, it sees something.
  • If it is an unknown device, then it’s probably that you needs to install the driver:
    1. Uninstall vBuilder
    2. Restart your PC (advisable)
    3. Install vBuilder
    4. RUN vBuilder
    5. Plug PLC
  • If nothing happens, check if the led of the PLC blinks. If not, check the power supply or maybe the power of your USB port.
  • Try to change the USB cable
    • Some USB cable can work with some devices, but not with all devices – due to the wire diameters of the USB cable
  • Try on another PC
