This page describes the use of the VTube-LASER to HERBER bender corrections using the HERBER MES protocol.

The protocol used is called "HERBER MES" and runs through a standard network connection - wired or wireless.

VTube-LASER uses the protocol to send bender part corrections to HERBER benders.

• The HERBER MES protocol is network protocol. It can be setup over a network or for use with a thumb drive.
  
  
• The protocol is unidirectional. Data only flows from VTube-LASER to the HERBER.
  
  
• Th reason it is unidirectional is because the HERBER control only needs to receive the bender ADJUSTMENT (or Correction) values alone to correct the bender. Because of this, the RECALL button in the VTube-LASER Bender Setup window is always disabled with the HERBER MES protocol.
  
  
• The HERBER MES protocol requires that you have nominal (master) data programmed in before you send corrections. VTube-LASER will stop the correction if it senses the wrong number of bends in the master data.

1. Load VTube.
   
   
2. Click on Systems Options in the toolbar at the top of the screen.
   
   
3. Enter the Measure 2 tab menu.
   
   
4. Enter the Setup Benderlink Network menu.
   
   

1. Choose an unused row in the grid for a new HERBER bender setup.
   
   
2. Assign a bender name that will help operators identify which bender this is. This text will be displayed at the top of the Bender Setup menu.
   
   
3. Assign the HERBER MES protocol.
   
   
4. Enter the path to the shared drive or folder in the NetPath field. This path should point to the HERBER folder that will receive MES files from VTube. (The value shown on the screen is only an example.)
   
   
5. Enter the IP address in the PING IP ADDRESS field if it is a fixed field. (This is not required. It allows VTube to ping the address to see if the network location is active before trying to open communications.)
   
   
6. If the HERBER rotates the Clockwise positive, then select YES in the CW Rotation Positive cell.
   
   
7. Press Close to save the settings. VTube will save these values to a persistent configuration file that will not change unless you change them in this grid.

1. The BENDER OUTPUT menu can be loaded from the NAVIGATION PANE. Inside that menu...
   
   
2. Select the bender number.
   
   
3. Click on "Send to Bender"
   
   
4. The Send to Bender Complete window will appear. This means that VTube has dropped the data file in the location where the UNISON control can automatically load the file and its data into UII.

In the YBC page, press the measuring center button.

1. Select the file that VTube-STEP just built. (You will need to find it on the network.)
   
   
2. Press "Read Nominals" button
   
   

Press the "BENDER SETUP button in the Navigation Pane.

Set the correct bender number at the top of the window.

You can select up to 100 different benders.

The Bender Protocol should say "Supravision Network". (This assumes that you have already configured VTube's Benderlink in the Systems Options as described in the previous VTube-STEP section.)

This is for first-time setup for a new part. Data in this window is separate from data in the main VTube-LASER window, so it is necessary to bring data into this window when performing first-time setup of a part. This ensures that the correct data is sent to the UNISON.

• Click on "Setup this Window" in the expanding menu on the right.
  
  
• Click on copy MASTER LRA to SETUP LRA.
  
  
• Be sure every field in the top panel has data that you want to send to the UNISON.
  
  
• The blue columns below will eventually be converted to new YBC data at the bender. So check for numbers there.
  
  

• Click on "Setup the Bender" in the expanding menu on the right.
  
  
• Click on "AUTO SEND the MASTER XYZ + BLUE Columns to the Bender".
  
  

A window indicating that data was sent should appear for a few seconds then disappear automatically.

In the YBC page, press the measuring center button.

1. Select the file that VTube-LASER just built. (You will need to find it on the network.)
   
   
2. Press "Read Nominals" button
   
   

Bend the tube in the UNISON bender.

Measure and align the tube to determine if it qualifies by falling within the envelope tolerance for the tube shape.

In the screen shot on the right, the red on the top left shows that the first END "A" LENGTH is out of tolerance.

Also, the red cells in the tangent point grid show that the measured tube centerline shape is out-of-tolerance.

Also - VTube is very visual. The solid model on the right shows exactly where the part is out is exceeding the tolerance. Click on the image to zoom in to see the values.

Click on the BENDER SETUP button in the Navigation Pane.

For dual screen systems, VTube-LASER will let you press the Switch Screens button in the upper right corner in order to move the Bender Setup window to the second screen like this:

See VTube-LASER Multiple Screen Support for more information about this feature.

Set the correct bender number at the top of the window.

You can select up to 100 different benders.

The Bender Protocol should say "Supravision Network". (This assumes that you have already configured VTube's Benderlink in the Systems Options as described in the previous VTube-STEP section.)

Press the measuring center button in the UNISON YBC screen.

You should now see the UNISON Supravision screen.

Check to be sure that the bender number is correct.

In the Bidirectional Communication menu on the right, click on RECALL.

RECALLING data is a critical step during correction. If a RECALL is not performed before a CORRECTION, then VTube may not be able make adjustments to the correct starting YBC data. Be sure to perform this step before performing the CORRECTION step below.

Important Note about UNISON benders: UNISON benders return whatever data is in memory. They do not attempt find the part on the UNISON disk based on the VTube-LASER part number. Whatever part is in the UNISON will be returned to VTube-LASER.

You can manually change the ADJUSTMENT values before sending corrections if you want to. Some users like to set the first and last Length adjustment to zero in order to keep the start position of the carriage in the same place - for when they have extra length on the ends.

If you want to, it is even possible to invert the rotation direction to keep the tube from hitting the bender during rotations.

Click on AUTO SEND. This will send the ORANGE columns to the UNISON bender.

A window should appear for a few seconds indicating that the Send to the Bender is complete.

You can allow this window to close on its own in a few seconds, or press the close button to close it immediately.

Move to the UNISON control and follow these steps:

1. Be sure the SVNET01.S2B file is selected. The bender number will always be part of the filename. For example, the file for bender 9 would shown as SVFILE09.S2B
   
   
2. Press "Read File" button.The Read File button will import corrected data.
   
   
3. Observe the changed data in the Correction Data values. (It will have changed.)
   
   
4. Press Apply to apply the changes to the control.

Bend the corrected tube starting in Step 1, then measure it again (Step 2) and follow the rest of the steps until the part is within tolerance.
