Runtime-based Recipe Management through Function Blocks

For applications that require programmatic control over recipe operations, a set of function blocks are available for recipe management.

• These function blocks give the PLC program full control over recipe operations at runtime.
• Examples:
  • Automatic changeovers triggered by a HMI selection.
  • Barcode scan.
  • Manufacturing execution system integration.
  • Sequence-driven production.

Important Notes

• Always monitor these outputs from the function blocks:
  • Done
  • Busy
  • Error
• Reset the Execute input between operations.
• Do not trigger the next function until the previous one completes.
