Downgrading DelatV controller from Version 11.3 to 10.3

Hi,

Is there any procedure to downgrade the controller of DeltaV from Version 11.3 to 10.3?

 

Thanks in Adv,

  • Yes, just run the controller upgrade utility on a version 10.3 system.
    Same process of taking a controller from 10.3 to 11.3 except you are doing in on a 10.3 system instead of the 11.3 system.

  • Remember you can't run S series controllers on v10.3.

    If you are using M series, then controller upgrade utility is the way to go. The utility will warn you that you are downgrading. Make sure you have all the latest 10.3 controller patches (or the patches that match your existing controllers if you need to stay consistent) on your pro plus or whatever station you use for the controller upgrade utility before performing the flash downgrade.
