DeltaV Control Studio - Parameter across different Control Modules

Hello,

I am hoping from some help on this subject.

My background is from SIEMENS and STEP7, so using the Cross Reference table was preety straight forward when it comes to debug some problems.

I have some parameters that can be changed according to different conditions that can be also in different control modules.

Is there a way to find all the actions/conditions that change a specific parameter so that I can do an easy debug ?

Thank you.

  You can use opcwatchit option: and from the watchit window browse to the specific parameter to be monitored.
  Run->watchit

  Karma doesn't have any menu, you get serve what you deserve.

  Thank you for your reply.
  
  Normally I use watchit to browse to a specific parameter and change it online.
  
  My concern is this case is different. for example:
  
  Control Module 1:
  
  If Condition X Then Variable X = 1
  
  Control Module 2:
  
  I Condition Y Then Variable X = 0
  
  Control Module 3 - Composite Block 1:
  
  If Condition Z Then Variable X = 0
  
  
  
  I was hoping to get a cross reference table for Variable X:
  
  Variable X:
  
  - Changed in Control Module X (Expression)
  
  - Changed in Control Module Y (Expression)
  
  - Changed in Control Module Z (Expression)
  
  The References option in the DeltaV Explorer only works for Control Modules and not Parameters inside them.
  
  Can you please help ?
  
  ´Thank you in advance

  In reply to gfradique:

  You can call up the 'References' for the module (Control Module 1). Here you find which parameters are changed from other modules.
  What you will not find is changes made by some form of dynamic references nor changes made when the module is included shared or private in another module.
  
  Remark:
  To change a parameter I would prefer to open the corresponding module On-line, so I get more information than just the plain parameters value.

  You can search any parameter from DV Explorer (Ctrl+F).
  It will give you a complete reference for that parameter.
