Bentley Instrument and Wiring - Create Multiple Cable and Terminal

I've used Instrument and Wiring for a few projects.  So far, my experience is good using this software.  I've also took 1 week course on Bentley I & W.  Here what we learned during course :

  • Design one loop ( like Flow Trans. and Flow Valve) and create for each instruments :
    • Terminal Tstrip (Tstrip Table)
    • Terminal Detail ( TERM table)
    • Cable ( Cable Table )
    • Cable Wire Detail ( Core Table)
  • After this, we save the loop as standard loop and use it as a template in creating future loops.

In practice what we do is the following: use instrument list created with Bentley P & ID or import instrument list (excel file) for standard P & ID.  We usually create specsheets after this.

The problem is after this step.  We already have a list of instruments ( with information and specsheets associate to them), but we cannot use standard loop template explain above because it apply only for new instruments, not for existing one.  We end up to manually create Tstrip and Cable detail for each instruments ( time consuming).  Is there a way to apply standard loop template to existing instrument (already created) ?

Thanks,

Eric

  • Eric,

    I understand your situation and believe have found a suitable solution for you.  Please follow the steps below:

    Please make sure that you already have your custom Loop Standards defined.  We will be building from this.

    1. Open I&W and then Layout Designer.

    2. When Prompted to Generate Loops for Instruments without Loops  - Select NO.

    3. In the Left Pane Navigation Bar select to view Instruments Only and filter to show all instruments ( Like *). This will add in your instruments that are not currently associated with a loop.

    4.Select all the Instruments you want to assign to a specific loop by using the Shift or Ctrl keys.

    5. Select the Associate button (See screenshot).

    6. In the Associate Dialog select "Create New Tag..."

    7. This will now prompt you to create a new Loop Tag and you will have the option to "Build From Standards".

    8. Once the Loop is build your select instruments will be associated to this new loop.

    For more details see attached screenshot.

    Thank you,

  • Hi Brandon,

    Thank you for your effort to find a solution.  I've tried your solution but it doesn't produce the result that I wanted.  Here what I did :

    • Create a standard loop with :
      • FT-100 and FV-100 instruments
      • TB-FT100 and TB-FV100 terminal strip (TSTRIP)
      • I-FT100 and I-FV100 Cable

    After that, I've created 2 new instruments FT-200 and FV-200 (without loop).   I've followed your step to create a new loop from the standard one.  But when I associate this new loop to FT-200 and FV-200, I now have a loop with 4 instruments (FT-100, FV-100, FT-200, FV-200) rather than having only 2 instruments ( FT-200 and FV-200).   Does the same thing happens on your side ?

    Thank you,

    Eric

  • Eric,

    I see what you are referring to here.  By default loops are built from standards and they are already assigned instruments.  But no problem this is why we allow users to create their own standards. I believe what you are going to have to do is create a new Instrument Loop from Standards and then you can use this as a standard later.  When you are in the Edit Loop dialog select the Instruments created and delete them.  Our goal is to create a Loop without Instrument in it.  Next we will save this as a Standard to be saved in the project.  Once this is created you can associate the instruments to a new loop that is created from this "blank" loop and only the instruments you assign will be associated.

    Please let me know your results.

    Thank you,

  • Hi Brandon,

    Yes, I think that this solution would be the best ( even if I have to re-attach cable and tstrip to the new instrument after these steps). Thank you for the suggestion.   I think we can close this item.

    Regards,
