Why is my connection with my ACE not working?

 

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
