What You'll Learn

• Configure historian storage
• Select tags for logging
• Create trend displays
• Query historical data

Prerequisites

• Tags configured in UNS
• Understanding of data retention needs

Step 1: Configure Storage Location

1. Navigate to Historian → Storage
2. Configure database:

Default SQLite (Development):

• Type: SQLite
• Path: Default or custom
• File Size: 1GB per file
• Auto-create: Yes

SQL Server (Production):

• Type: SQL Server
• Server: SQLServer\Instance
• Database: FrameworX_History
• Authentication: Windows/SQL

Step 2: Create Historian Tables

1. Go to Historian → Tables
2. Create table:

Process Data:

• Name: ProcessData
• Type: Continuous
• Storage: 1 second resolution
• Retention: 90 days
• Compression: Deadband

Production Counters:

• Name: Production
• Type: Counter
• Storage: On change
• Retention: 365 days

Step 3: Configure Tags for Logging

1. Navigate to Historian → Tags
2. Add tags to log:

Analog Value:

• Tag: Tank1_Temperature
• Table: ProcessData
• Deadband: 0.5
• Rate: 10 seconds

Digital Value:

• Tag: Motor1_Running
• Table: ProcessData
• Log: On change only

Production Count:

• Tag: Units_Produced
• Table: Production
• Type: Counter/Totalizer

Step 4: Create Trend Display

1. Open Displays → New
2. Add TrendChart control
3. Configure:

Basic Setup:

• Duration: 1 hour
• Update: 1 second
• X-Axis: Time
• Y-Axis: Auto-scale

Add Pens:

• Pen 1: Tank1_Temperature (Blue)
• Pen 2: Tank1_Pressure (Red)
• Pen 3: Motor1_Running (Green, digital)

Step 5: Configure Trend Features

Time Navigation:

• Enable pan and zoom
• Add time selector
• Quick ranges: 1hr, 8hr, 24hr, 7 days

Analysis Tools:

• Cursors for value reading
• Min/Max/Average display
• Export to CSV

Step 6: Query Historical Data

Using SQL queries:

sql

SELECT Timestamp, TagName, Value 
FROM ProcessData
WHERE TagName = 'Tank1_Temperature'
  AND Timestamp > DATEADD(day, -7, GETDATE())
ORDER BY Timestamp

Using Scripts:

csharp

DataTable history = @Historian.GetData(
    "Tank1_Temperature",
    DateTime.Now.AddDays(-7),
    DateTime.Now,
    1000  // Max points
);

Step 7: Create Reports

1. Reports → New
2. Add data source:
   • Type: Historian Query
   • Tags: Select multiple
   • Period: Shift/Day/Month
   • Aggregation: Average, Min, Max

Step 8: Storage Management

Configure data management:

Compression:

• Deadband: ±0.5% of range
• Time deadband: 60 seconds
• Compression deviation: 1%

Archiving:

• Archive after: 30 days
• Archive location: Network path
• Compression: ZIP

Purging:

• Auto-purge: After retention period
• Manual purge: By date range

Step 9: Test Historian

1. Start Runtime
2. Let run for few minutes
3. Open trend display
4. Verify:
   • Data logging active
   • Trends updating
   • Historical data visible
   • Zoom/pan working

Performance Optimization

• Log only necessary tags
• Use appropriate deadbands
• Consider table partitioning
• Regular index maintenance
• Monitor disk space

Best Practices

• Plan retention requirements
• Use multiple tables for different data types
• Set appropriate logging rates
• Regular backups
• Document data retention policy
