This page describes the use of the VTube to UNISON Supravision file communications. Descriptions for VTube-STEP and VTube-LASER are included.

VTube-STEP can send data directly to the CRIPPA UII software YBC values.

VTube-LASER can correct data in CRIPPA UII for YBC bender corrections.

• Connect the CRIPPA bender to the network following the CRIPPA tech support instructions.
  
  
• Be sure that ethernet cable 2 is plugged into Ethernet port 2 on the CRIPPA HMI computer. The cable is stored initially under the keyboard shelf. You will need to drop the bottom of the shelf and uncoil the cable through the back like shown on the right.
  
  
• Plug in cable 2 to port 2, then cable tie the cable to the other cables so that it will not bind when the door closes.
  
  
• Be careful to NOT unplug or replace cable 1. This cable allows the CRIPPA software to communicate with the PLC inside the bender.
  
  

• Find cable 2 inside the electrical cabinet on the back of the bender. This is the other end of the same cable you plugged into the CRIPPA HMI computer in the previous step.
  
  
• Plug this end of the cable into a network switch.
  
  
• Plug another cable from the network switch into the VTube computer.
  
  

The technician will...

1. Setup the IP address inside the CRIPPA HMI computer and inside the VTube computer
   
   
2. Setup Supravision network communications.
   
   
3. Share a CRIPPA folder and setup permissions for the VTube computer to read and write data to that folder.

The technician will...

1. Setup the IP address inside the CRIPPA HMI computer and inside the VTube computer
   
   
2. Setup Supravision network communications.
   
   
3. Share a CRIPPA folder and setup permissions for the VTube computer to read and write data to that folder.

Test the network connection at the VTube computer using the Windows File Explorer.

1. Open the File Explorer.
   
   
2. Type in the network path for the CRIPPA computer. It is safest to use a fixed IP in the path like this: \\192.168.2.6
   
   (The 192.168.2.6 is an example IP address. The number you will use will most likely be different.)
   
   
3. Press Enter and allow the VTube to connect to the CRIPPA computer. This may take a few seconds.
   
   
4. The CRIPPA computer will ask you to supply credentials (username and password).
   
   
5. Enter the credentials supplied by the CRIPPA or Advanced Tubular technician, then be sure the check the "Remember my credentials" checkbox before pressing OK.
   
   
6. If the connection works, then you will see a couple of folders in the File Explorer screen. One of them will be something like "SVTransfer". Double click on that folder. The path that you see in the top of the Explorer window is the path you will need to program into VTube for communications to the CRIPPA. So, for this example, the path to use in setting up VTube is "\\192.168.2.6\SVTransfer".
   
   
7. Attempt to create a new text file in this folder. If you can, then the network connection is complete. VTube must be able to write files to this folder.

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 CRIPPA bender setup. (Click on the image at the right to see a zoomed image.)
   
   
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 CRIPPA SVNet protocol.
   
   
4. Enter the path to the shared drive or folder in the NetPath field. This path should point to the CRIPPA folder that will receive command 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 Crippa rotates the Clockwise positive, then select YES in the CW Rotation Positive cell.
   
   
7. The "Ignore Incoming Linear Unit" setting is optional. This will not allow the CRIPPA to change the linear units in VTube-LASER if they are different.
   
   SOME CRIPPA BENDERS ALWAYS SEND DATA IN MILLIMETERS - EVEN IF THE LINEAR UNIT SETTING IN THE FILE IS SET TO INCHES. THIS SETTING MUST BE ENABLED TO OVERCOME THAT ISSUE. IF THIS IS THE CASE, THEN IT ALSO IMPORTANT TO RECALL WITH VTUBE-LASER SET TO MILLIMETERS.
   
   
8. 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 CRIPPA control can automatically load the file and its data into UII.

CRIPPA will ask for confirmation to update when it receives the incoming data. Say "Yes".

The YBC data will change to match the data that was sent from VTube. You can compare a few values to be sure the data was updated properly.

1. Save and Compile, then Save the CRIPPA data again. (The UII program will ask you to save the data twice.)
   
   
2. Run the simulation (if you want to).
   
   
3. Setup and bend the part.
   
   

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.

You should see a CRIPPA SupravisionNET icon at the top left corner of the screen. The Bender Protocol should say "CRIPPA SVnet". (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 CRIPPA.

• 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 CRIPPA.
  
  
• 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.

Move to the CRIPPA control. CRIPPA will ask for confirmation to update when it receives the incoming data. Say "Yes".

If you don't see this green banner, then communications did not occur. You will need to trouble-shoot the connection to make it work.

The YBC data will change to match the data that was sent from VTube. You can compare a few values to be sure the data was updated properly.

Bend the tube in the CRIPPA.

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. The length is 0.054" long.

Also, the red cell in the tangent point grid on the lower right shows that the measured tube centerline shape is out-of-tolerance because the deviation is 0.121".

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.

You should see a CRIPPA icon at the top left corner of the screen. The Bender Protocol should say "CRIPPA SupravisionNET". (This assumes that you have already configured VTube's Benderlink in the Systems Options as described in the previous VTube-STEP section.)

Be sure the that the Part Number value is the same as the part name in the CRIPPA control. The CRIPPA will not return data unless it recognizes the part number.

Remember that the CRIPPA UII will only return data from the part that is SAVED TO THE DISK. It will not return UNSAVED data in the UII screen.

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.

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 CRIPPA bender.

To be sure that a RECALL has recently been performed, VTube will show a CRIPPA CORRECTIONS NOTES as a reminder.

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

Move to the CRIPPA control. CRIPPA will ask for confirmation to update when it receives the incoming data. Say "Yes".

If you don't see this green banner, then communications did not occur. You will need to trouble-shoot the connection to make it work.

The YBC data will change to match the data that was sent from VTube. You can compare a few values to be sure the data was updated properly.

The VTube-LASER SEND will only update the UII data on the CRIPPA screen. (Remember: CRIPPA only returns data from the file - see "RECALL" above.) This new data that the CRIPPA UII screen just received from VTube-LASER must be SAVED to the disk and compiled to take effect.

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