Protecting your engineering standards

Protect a parameter in a class-based template

Protect a parameter in a class-based template from the class. There are two ways to do this; both have the same result:

Method 1

  1. Open DeltaV Explorer.
  2. Select the parameter in the class on which the template is based and select Properties from the context menu.
  3. Make sure the Allow instance value to be configured check box is not selected.
  4. Repeat steps 2 and 3 for other parameters as desired.

Method 2

  1. Open DeltaV Explorer.
  2. Select the class on which the template is based and select Configure Instance from the context menu.
  3. Open the Parameters tab.
  4. Click, CTRL+click, and SHIFT+click to select the parameters to protect.
  5. Click Remove.

This sequence of actions has the same effect as opening the Properties dialog of each parameter and deselecting the Allow instance value to be configured check box. 

It is not possible to remove the protection in instances of the module made from the template.

Protection is not automatically preserved during a manual database export and import. To preserve protection when manually exporting and importing a database, check the Include the data for a DeltaV software upgrade check box. Note that you can only do one online upgrade import.

However,  protection is automatically preserved when a DeltaV installation is upgraded with the DeltaV Upgrade Wizard.
