To model asynchronous event handling, use the Thread Trigger block. This block connects to I/O boards and detects hardware interrupts.

See About RTOS Tasks and Priorities.

Speedgoat^® provides an interrupt setup block to configure interrupts for I/O modules. See the Speedgoat I/O Blockset and documentation. Concurrent execution with explicit partitioning of tasks is not supported by the Speedgoat Interrupt Setup block.
