Before Start-Up
  • Before connecting PLC to PC :
    • Install vBuilder
    • Restart your PC (advisable)
    • RUN vBuilder
    • Plug PLC
    • If you have some issues, please, have a look here
  • PLC may be powered via USB (except Ace 7096) or 5V on power plug. You can plug both at the same time.
  • Before wirring PLC (outputs) :
  • To enable PLC to start up program after power cycle, in vBuilder, press the V program button then press the green triangle run button . Now you are free to cycle PLC power. PLC will start program on power up.


Tips and tricks

Upload a program without disclosure the code

With vBuilder you may « Program to File », so the user doesn’t see the actual code. They would use the « Program from File » function to program the device. This also takes care of starting the program, so it’s very easy for the end user.

Flow Chart: Insert or delete a line or column

With vBuilder you may insert or delete a line or column just by fly over the rules. Just click for insert a line or column or press [Ctrl] key and click for delete it.

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

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:

Check in your Windows device manager (devmgmt.msc) if you see VelocioComm

if not, try these :

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, the 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 wires diameter of the USB cable)
Try on another PC
