What is a hardware interrupt? The technology module will trigger a hardware interrupt as configured in response to specific events/states.
  • Page 90 Interrupts/diagnostic messages 5.3 Hardware interrupts Feedback bit STS_DIR is preassigned with "0". A hardware interrupt is not triggered when the first counter value or position value is changed immediately after switching on the technology module in down direction. When the hardware interrupt is enabled, for system-related reasons it can also be triggered if "0"...
