Batch Add Alarm Extensions Without Vykon Modules

Topic: Niagara Workflow, Alarms
Difficulty: Advanced

Overview

Add alarm extensions to multiple points without Vykon modules. Explore alternative methods when the standard batch editor cannot add extensions.

The Problem

Niagara's built-in batch editor can modify existing properties but cannot add new extensions like AlarmExtension to points. Vykon modules provide bulk tools, but they're not always available.

Solution Methods

Method 1: Robot/Program Object Automation

Use Niagara's built-in scripting capabilities:

1. Create a ProgramObject in your station
2. Write a script that iterates through points
3. Add AlarmExtension to each programmatically

// Pseudo-code concept
for each point in targetFolder:
  if not hasExtension(point, "alarm"):
    addExtension(point, new AlarmExtension())
    configureAlarmLimits(point, highLimit, lowLimit)

Method 2: Export/Modify/Import

1. Export station or folder to .bog file
2. Edit the XML to add alarm extensions:

<n:p n="alarmExtension" m="a">
  <n:p n="alarmEnable" v="true"/>
  <n:p n="highLimit" v="80"/>
</n:p>

1. Import modified .bog back into station

Method 3: Copy Template Approach

1. Create one point with properly configured alarm extension
2. Save as template
3. Use template to create new points (alarms included)
4. Rebind to actual I/O

Method 4: Custom Module Development

For large-scale needs, develop a custom module with bulk alarm tools.

Step-by-Step: Export/Import Method

1. Right-click target folder > Copy
2. Save as BOG file
3. Open in text editor
4. Find <n:p n="out" sections
5. Add alarm extension XML after each
6. Save and import via Paste

Best Practices

• Test on small subset first
• Back up before bulk operations
• Verify alarm routing after addition
• Document your process for repeatability
