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

Network 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.

HERBER MES Data Protocol Information
These are important facts to know about this protocol.
- The HERBER MES protocol is network protocol. It can be setup over a network or for use with a thumb drive.
- The HERBER MES protocol is only for correction of the bender - not NEW PART setup. For new part setup, see the HERBER SOL protocol.
- 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.
- Therefore, 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.

BENDERLINK SETUP STEPS FOR VTUBE-LASER
- Click on Systems Options in the toolbar at the top of the screen.
- Enter the Measure 2 tab menu.
- Enter the Setup Benderlink Network menu.
|
|
STEP 2: Setup the Benderlink Network Grid for HERBER MES Protocol
- Choose an unused row in the grid for a new HERBER bender setup.
- 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.
- Assign the HERBER MES protocol.
- 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.)
- 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.)
- If the HERBER rotates the Clockwise positive, then select YES in the CW Rotation Positive cell.
- 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.

How to SEND CORRECTION Data to the HERBER Control from VTube-LASER
STEP 1 - Bend the Tube
|
Bend the tube in the HERBER bender.
|
 
|
STEP 2 - Measure the tube with VTube-LASER
|
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.

|
STEP 3 - Enter BENDER SETUP
|
Click on the BENDER SETUP button in the Navigation Pane.
|
|
STEP 4 - Choose the BENDER NUMBER
|
Set the correct bender number at the top of the window.
You can select up to 100 different benders.
The Bender Protocol should say "HERBER MES". (This assumes that you have already configured VTube's Benderlink in the Systems Options as described in the previous section.)
|
|
STEP 5 - Put the UNISON Control in COMMUNICATIONS Mode
|
If this is the first correction, then the Bender Setup screen may show no data. If this is the case, then it is necessary to update the Bender Setup screen from VTube-LASER's main memory like this:
- Press "Setup this Window".
- Press "Copy Master LRA to Setup LRA".
|
|
STEP 5 - At VTube-LASER, RECALL the UNISON YBC data
|
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.
|
|
STEP 6 - OPTIONAL STEP - You Can Manually Change the ADJUSTMENT Values
|
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.
|
|
STEP 7 - Send the CORRECTION Values to the UNISON
|
Click on AUTO SEND. This will send the ORANGE columns to the UNISON bender.
|
|
STEP 8 - The SEND to BENDER Complete Window
|
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.
|
|
STEP 9 - IMPORT the Correction Data at the UNISON Control
|
Move to the UNISON control and follow these steps:
- 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
- Press "Read File" button.The Read File button will import corrected data.
- Observe the changed data in the Correction Data values. (It will have changed.)
- Press Apply to apply the changes to the control.
|
|
STEP 10 - REPEAT STEPS 1 THROUGH 9
|
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.
