VTube-LASER uses the legacy Eaton Leonard Current Loop protocol to communicate with Premier controls. The protocol requires that an RS-232 signal be converted to Current Loop, then sent to the bender.

This diagram demonstrates how a Benderlink Ethernet Module completes the Current Loop connection between a FARO VTube-LASER computer to an Eaton Leonard Premier, or EL-2000 bender control.

The Benderlink Ethernet Module can be wired or WiFi wireless (optional).

All communications from the PREMIER control occurs in the VECTOR 1 screen shown here.

VTube-LASER knows how to communicate using the VECTOR 1 protocol.

When you enter this screen note that the REQUEST TRANSFER box on the right is BLACK. This means that the Premier is not ready for communications yet.

To put the Premier in communications mode, make the REQUEST TRANSFER box active (green) like is shown here. The WAITING field will be highlighted.

Before you make that button active, check on the following settings:

CHECK 1 - CORRECT MODE IS ACTIVE
The MODE in the upper left corner should read "EXTERNAL MODE". It is controlled by the yellow button on the bottom right side of the screen. This mode allows VTube-LASER to control the communications.

CHECK 2 - BENDER NUMBER MATCHES
The bender number in both this menu and the VTube-LASER Benderlink setup must agree. If they don't, then VTube and the PREMIER will at least issue warnings or dialogs.

CHECK 3 - CORRECT PART NAME IS ON THE SCREEN
If you plan on using the RECALL inside VTube-LASER, then it is important that the correct part name shows in the Part Name field.

If the part names don't match during a VTube-LASER RECALL, then communications will fail. (VTube-LASER sends a 4 byte request, then the PREMIER returns a short 20 byte answer - which is not an entire part, then VTube will time-out.)

Before sending data to a legacy Eaton Leonard control, you can completely setup the control inside VTube-LASER if you have VTube-LASER version 2.7 or greater. VTube-LASER will allow for the complete setup of all bender and setup data that can be stored in a Premier, EL2000, or Velog control in the Eaton Leonard Setup window.

Sending a NEW Part

1. If the blue columns only have zeros, or there are no rows in the LRA grid, bring new part data into the Bender Setup window by using the Setup this Window button on the right. Click on "Copy MASTER LRA to Setup LRA".
   
   
2. Press the "Additional Bender Data" button at the top of the Bender Setup screen to load the Eaton Leonard Setup window. Edit any of the Eaton Leonard setup values and Save and Close that window.
   
   
3. Press "Setup the Bender" on the right.
   
   
4. Press "AUTO SEND" on the right. (Be sure that the bender is ready for communication. See the "Premier VECTOR 1 Menu With Communications Active" section above.)
