About component tracking

Use component tracking to determine whether tracked components have been changed. The
Logix Designer
 application creates an overall tracked value to indicate the current state of tracked components.
Tracked components and their current states appear in the Tracked Components dialog box, which is accessible on the Controller Properties dialog box - Security tab. The following components can be tracked:
  • Routines
  • Add-On Instructions
  • I/O Modules
  • Constant tags
Recommended limits for tracked components
The following table lists the recommended limits on the number of components that can be tracked. If the limits are exceeded, there might be a noticeable impact on performance in the
Logix Designer
 application.
TIP:
To optimize performance, configure component tracking so that the tracked state value is calculated on demand rather than at regular intervals.
