DeltaV Simple timer

Hello,

    I am new to DeltaV,   Not new to programming.    I was curious if anyone had any documentation, or guides on assisting me with adding a simple timer with a setpoint alarm (ie: timer reaches one hour, display alarm) to one of my DeltaV pages.  

It doesn't need to be attached to anything, just the page.

  Consider using a retentive timer block in a control module. You can then create an alarm off the timer complete flag, then use that to create animations/text in operate configure mode.

  I created a timer object by copying from another location, renaming and placing it within the area I want the new one...
  I then go to try and create the object on the graphic by right clicking and selecting quick edit> it brings up the graphic editor with all the controls.
  
  From here, I can add new datalink object then point it to my control I previously created, but it always gives me an error, "Source does not exist"
  
  Like I mentioned, I am pretty new to DeltaV

  Have you assigned the module to a controller and downloaded it? You will receive that error if not.

  Have you looked at the conditional alarming available on the alarm, AI, PID etc. function blocks? You can set an on delay timer for each alarm, and the alarm will only be set when the value has been true for that time period. So, you can set it such that if the PV is greater than 50 for 1 hour the alarm is activated. The ALM block can be used if the alarm is analog, and not on an AI or PID.
  For these function blocks, right click on the block, select assign alarm, and then check the box to enable conditional alarming. You will then see the settings on each alarm.

  Thank you everyone for the help/Pointers. I was able to get this working!
  
  Side Note, Is there any language that's similar to what control studio uses? Or anything that would help be more proficient?
