We are trying to connect a PC with PLC 140 CPU65150 with Unity Pro XL by USB Port. When with try to make a connection with software the system gives the following message:
Failed To Connect to the currently select target, this is not a valid PLC address, or PLC is busy, or media is OFF

But when we check the communication parameters driver setting, the icon shows the following:
Virtual Port: COM2
Status: Connect
Remote IP:90.0.0.1
Local IP:90.0.0.2

Please help us with this.

Thanks in advance.
 
There are a couple of things you must check. The settings you mentioned with regards to the Drivers Manager (I think) is for the USB connection to a M340.

If you have used this cable with another Schneider PLC, maybe just reset the driver and retry.

Make sure in Unity you have selected the standard mode and not simulation mode. If this is ok, check Unity under plc>set_address that your PLC address is "SYS" and the media is Unitelway. Test the connection.

If you have not used this cable before the follow the next steps:
You need to plug in your connection cable and go into your control panel>system>hardware>device manager and check what com port the computer sets the cable. Then go back to your Schneider drivers manager and setup a new Unitelway driver. You shouldn't need to change any settings for that driver. Just type in the correct com port.

When finished click ok and apply your changes. Try to connect again.
 
Disconnect Ethernet cord before connection via USB. Connection parameters: USB/SYS. And you need PLC USB driver.

Unitelway!!!!!!!!!!

Quantum talks in Modbus protocol (Only Telemecanique has Unitelway protocol).

Regarding the USB connection with Unity you have to know that related to the Quantum controller you need just to set USB and no other because the communication is peer to peer and no address is request (it is implicit).

Check rather the COM port configured for USB in your PC and of course the cable.

When you installed Unity Pro, did you install the driver? If not, run the install to add drivers.

Obvious but ??? Did you set first the connection type to USB and SYS? Try SYS or blank or 0 (zero) but SYS should work.

The USB connection always works and is the ideal method to connect to a PLC when you do not know the address or comm parameters.
