Learn FANUC-KAREL-TP-EXTENSIONS with Real Code Examples

KAREL is used for advanced CNC and robot programming beyond standard G-code.

Supports structured programming with variables, conditionals, loops, and subprograms.

TP Extensions enhance the teach pendant interface with custom dialogs, menus, and automation tasks.

Enables integration with sensors, vision systems, and external devices.

Widely applied in industrial automation, robotics, and complex CNC machining workflows.

Subprograms, loops, and conditional logic

Data management via arrays, records, and files

Real-time machine state monitoring

Teach Pendant UI customization

External device communication via fieldbus or network

PROGRAM - main KAREL program structure

SUBROUTINE - modular reusable code block
