Optimize Performance

Apply these guidelines to minimize program scan times and facilitate the fastest possible switchover:
  • Use periodic tasks—Schedule tasks at regular intervals to balance processing loads.
  • Minimize the number of programs—Reduce complexity by consolidating logic into fewer programs.
  • Manage tags for efficient crossloads—Organize and optimize tag usage for faster data handling.
  • Use concise programming—Write streamlined, efficient code to minimize overhead.
  • Reduce controller communication—Limit unnecessary data exchanges between controllers.
  • Use program-scoped tags—Scope tags locally within programs to reduce global tag overhead.
  • Minimize data transfer—Avoid excessive data movement to improve system responsiveness.
  • Minimize instruction operation—Simplify logic to reduce processor workload.
  • Minimize alarm conditions—Prevent unnecessary alarms to reduce system strain and improve stability.
