Hardware interrupts
Hardware interrupts
The DI 16×24VDC HA generates a hardware interrupt for the following events:
• At a rising edge (signal change from 0 to 1)
• At a falling edge (signal change from 1 to 0)
Interrupt OBs are called automatically if an interrupt occurs.
The module channel that triggered the hardware interrupt is recorded in the start information
of the OB40 in the OB40_POINT_ADDR tag. The figure below shows the assignment to the bits
of local data double word 8.
