Event Frame Attribute Queries

Hi all,

 

I am trying to use the element template framework to compute aggregate values whenever a phase completes on my DeltaV System.

 

I have created an element template for each equipment class in my system.   Similar to the one depicted below.

Next, I built an equipment template on each equipment in the class, and assigned the tags that are relevant for the equipment to the template as shown below.

Lastly, I built the event frame template to fire every time a phase executes.

Now when I compute the values, I am getting two types of errors.

 

1. The first one appears to be related to the Count aggregate, and how the UOM for the count is different than the instrument.   I have the default UOM of the count aggregate set to 'none' for the count aggegate, but it is still throwing the error.   How can I adjust my solution to eliminate this error.

2. For the equipment classes that do not have the full complement of instrumentation, I am getting errors that imply cannot compute aggregate because the instrumentation can t be found.  It is almost like there should be a equipment class specific event frame template  How can I adjust my solution to eliminate this error..
