Utilities

Utilities provide core data processing, timing, and asset generation features without requiring external systems. Use these classes to manage internal App logic and behavior.

Available utility classes

Class	Description
Barcode generation	Generates 1D and 2D barcodes or QR codes as images or binary data.
Counter	Manages numerical values, such as production counts or sequence numbers.
Cron	Schedules automated tasks using standard cron expressions.
Data processing	Manipulates data by merging objects, filtering arrays, or mapping value ranges.
Data simulation	Generates synthetic data points to test logic before connecting physical hardware.
Event simulation	Triggers mock events to verify that reactive flows respond correctly.
PDF processing	Splits, merges, or modifies existing PDF documents.
PDF templates	Generates PDF documents by merging App data with pre-designed layouts.
Stopwatch	Measures time intervals using a high-resolution timer.
Timer	Runs countdowns, maps progress to custom ranges, and introduces delays into flows.
Users	Manages users and App access programmatically.

Testing with simulated data

Use data and event simulation nodes to test logic during the initial development phase. This verifies that dashboards and databases work correctly before connecting to a physical PLC or sensor. Once the logic works, replace the simulation classes with actual connectors.
