DeltaV Device Commissioner "Sensing Failed"

v14LTS w/ v14.5AMS

Having an issue with DDC not scanning CIOCs. Simply says sensing failed, nearly instantly. Nothing in any of the various logs seems to indicate what the problem may be. Licensed (as in we have Configuration Studio) and set-up per the white paper and identical to another working system. 

Users all have the Can Edit and Can Set Up Devices keys for the auto commissioning functions. 

Noticed that in I/O studio where the user would typically show up it says <none>.

Can find no KBA on the GSC website related to this issue. 

Has anyone else run into this issue?

  • What does your DeltaV Explorer indicated you are log in as? You can find your DeltaV Exp log in at the bottom right. Were you able to launch AMS Device Manager from the device and see it's status?

    Config All/Download All, and yes AMS was working normally. Unrelated but rolling back to 14.3 today as 14.5 became unstable.

    sorry you are having issues with AMS DM 14.5. I don't see this issue and the performance it outstanding with AMS DM 14.5 or newer. Before rolling back to AMS 14.1.1. I suggest you call in to GSC for support. I have not run into this issues and they can look at the log files and see where is the issue may be.

    That decision to roll back was made in consult with the impact partner. From conversations with other sites who had been told not to go to 14.5 I think there is a disconnect somewhere.

    The performance was never as good as the previous version from an end user perspective. Slow and glitchy and many failed "saves" on a system that never had issues prior.
  • So this issue is not resolved:

    • Works fine on my laptop without AMS
    • Does not work at 2 sites that I actively work at
    • Works at 1 site and not at another that a friend manages
    • All systems v14LTS
    • AMS v14.5 and 14.1 mix 
    • No real answers from GSC

    AMS 14.5 has many improvements over 14.1.1, especially on larger systems. Could you be more specific as to your issues on AMS or is it all related to the Smart Commissioning? Have you checked that both the user account you are using has permissions in both DeltaV and AMS?

    I know it's frustrating to have this problem, but a quick search on my end didn't find this issue as a common one, so it's probably taking a long time to replicate (if we even can). It's easy to get frustrated but as someone on the other side, it's equally as frustrating for me because it can take hours of testing and trials to attempt to recreate an issue that can be fixed.

  • Sense has absolutely nothing to do with AMS Device Manager, it's done by DeltaV itself.
    What DeltaV Build are you using?
    From which station have you being trying to run DDC?
    Have you created the Device Place Holders?
    I see you have created a new Smart Commissioning Policy called "TEST", how did you set it up?

    Cheers,
