  2. Right-click the mouse and Copy (Ctrl+C)
  3. Select the TankFarm
  4. Paste (Ctrl+V)
  5. Rename the folder
  6. Repeat the process to create Tank3
  7. Paste again and replace for Tank3

2. Create Production Tags

Used for counters, batching, and KPI calculations:

  1. Add production tags:


NameTypePathDescription
Production_CountIntegerProductionUnits produced
Production_RateDoubleProductionUnits per hour
Batch_IDTextProductionCurrent batch identifier
Batch_StartDateTimeProductionBatch start time
Shift_NumberIntegerProductionCurrent shift (1-3)
Quality_ScoreDoubleProductionQuality percentage


    

In order to create those tags quicker, just copy copy-paste this table

  1. Select the entire table, include the titles (Name, Type, Path, Description)
  2. Open Unified Namespace →Tags
  3. Right-Click on the first row (insertion) row and execute PASTE
    1. if by mistake you left-click, instead of right click, you selected one specific cell to edit
    2. If that happen, either press ESC, or click with the mouse outside the grid area, to close that editing. 
  4. This command will automatically create the Production folder, and the tags.
  5. Navigate to Unified Namespace →Asset Tree to confirm the tags are in the expected folder


3. Create Equipment Tags

For motor control and equipment status:

  1. Create folder: Equipment
  2. Add equipment tags:
NameTypeFolderDescription
MotorRunningDigitalEquipmentMotor on/off
MotorSpeedDoubleEquipmentMotor RPM
MotorCurrentDoubleEquipmentMotor current (Amps)
MotorHoursDoubleEquipmentRun hours
ConveyoSpeedDoubleEquipmentBelt speed (m/s)


Use similar expedite process you used for the other tags

4. Configure Tag Properties

Set Retentive Values

For production counters:

  1. Select Production_Count
  2. Enable Retentive checkbox
  3. Preserves value through restart


5. Create Motor UserType

Build a reusable template:

  1. Navigate to Unified Namespace → UserTypes

    • Running (Digital)
    • Speed (Double, 0-3600 RPM)
    • Current (Double, 0-100 Amps)
    • Hours (Double, retentive)
    • FaultCode (Integer)
  4. Return to Tags
  5. Create instances:
    • Name: Motor2, Type: MotorType
    • Name: Motor3, Type: MotorType

6. Create System Tags

For scripts and calculations:


NameTypeInitial ValueDescription
System_RunningDigital0System status
Calc_AverageDouble0Calculated average
Alarm_CountInteger0Active alarm counter
Report_TriggerDigital0Report generation trigger


7. Test Your Tags

  1. go to Runtime → Startup
  2. Click Run Startup
  3. Open Unified Namespace → Asset Tree
  4. Verify:
    • Tag values 
    • Folder structure visible
    • UserType instances expanded
