Overview

In OpenPlant PID Update 10, Instrument can be shown with different safety critical identification.

For Example "Safety Critical Element" property can be added to the instrument classes that allows to select "Yes/No" to indicate if the instrument is safety critical or not. It also enables to change the graphics with a different symbol to visually indicate the type of safety critical instrument.
 
In this wiki article, we will explore the implementation to achieve such requirements.

Steps To Accomplish

A. Adding new cells as Safety Critical Symbols

1. Load OpenPlant PID CONNECT Edition and open a drawing.
   
   
   
   
2. Navigate to Common Tools ribbon group and draw a circle of desired radius.
   
   
   
   
3. Go to Annotate ribbon tab. Click on Expand ribbon button in Cells ribbon group to open the Cell Library Dialog Box.
   
   
   
   
4. Attach the desired cell file by selecting Attach File. In this case, instrument.cel has been used.
   
   C:\ProgramData\Bentley\OpenPlant CONNECT Edition\Configuration\WorkSpaces\TrainingWorkspace\WorkSets\Training_Workset\Standards\OpenPlant\PID\cell
   
   
   
   
   
5. Select element and Define Cell Origin. It is recommended to have the origin at the center of the cell elements. Click on Create in Cell Library Dialog Box.
   
   
   
   
6. Enter Details in Create Cell Dialog Box.
   Note :- Keep the cell type as Graphic
   
   
   
   
7. In similar way, create cells for Triangle and Square shapes.
   
   

B. Concept of defining Offset & Direction for the cell.

1. X offset
   
   
   
   
   
   
   
2. X Direction
   
   
   
   
   
   
3. Y offset from cell origin
   
   
   
   

   For Triangle Cell

   Y Offset Set = 0.5 mm

   Bubble Radius = 6 mm

   Y Direction =  1 (Top)

    

   Formula Given:-

   (Y Offset + Bubble Radius)*Y Direction

   (0.5 + 6)*1 = 6.5mm (From center of instrument)
   
   
   
4. Y Direction from cell origin
   
   
   

C. Adding of Properties to Instrument Class.

1. Load Bentley Class Editor V8i.
   
   
   
   
2. Open OpenPlant_PID.01.08.ecschema.xml schema and supplement with OpenPlant_PID_Supplemental_Design.01.08.ecschema.xml schema.
   
   
3. Navigate to Instrument Parametric Class. Go to Properties and click on Add > New to create New Property as SAFETY_CRITICAL1.
   
   
   
   
4. Fill the Property detail as given Below. Make sure that property type is Boolean.
   
   
   
   
5. Right click on property SAFETY_CRITICAL1 and add custom attributes as shown below.
   
   
   
   
   
   
   
6. Add details in Extended cell Settings custom attribute as shown below.
   
   
   
   
7. Enter details for Category custom attribute as shown below.
   
   
   
   
8. For Property Custom Attributes, set the changes as shown below.
   
   
   
   
9. Create two more properties as SAFETY_CRITICAL2 and SAFETY_CRITICAL3 for circle and square shaped cell respectively.
   
   
   
   
10. Add the same custom attributes that have been used to SAFETY_CRITICAL1 Property. Enter details as shown below.
    
    SAFETY_CRITICAL2
    
    
    
    SAFETY_CRITICAL3
    
    
    
11. Navigate to Instrument Parametric Class and Add Extended Cell Property Names Custom attribute.
    
    
    
    
    
    
12. Right click on Property Names and select Add element.
    
    
    
    
13. Enter details for the property names as shown below.
    
    
    
    
14. Save all changes in Class Editor and Reload OpenPlant PID CONNECT Edition.
    
    
15. Place Parametrics Instrument. Right Click and go to Properties.
    
    
    
    
16. Verify the results by changing Properties from False to True.
