Triggering a hardware interrupt
In the event of a hardware interrupt the CPU interrupts the processing of the user program
and processes the hardware interrupt OB (for example, OB 40). The event that led to the
triggering of the interrupt is entered in the start information of the hardware interrupt OB.
11.2.5.3 Triggering of a pull/plug interrupt
Introduction
If your remove an IO-Link device or interrupt communication, a pull interrupt is generated by
the assigned submodule.
A plug interrupt is triggered as soon as the IO-Link device is plugged in again or IO-Link
communication re-established.
Triggering of a pull/plug interrupt
In the case of a pull/plug interrupt, the CPU interrupts the processing of the user program and
process the pull/plug OB (OB 83). The event that led to the triggering of the interrupt is
entered in the start information of the pull/plug OB.
11.2.6 Maintenance events
Introduction
All IO-Link events of the type warning which the IO-Link device generates are mapped to the
maintenance interrupts of the assigned submodule. The objective is early detection and
elimination of potential disturbances.
With the IO-Link master, maintenance events indicate to the user when a check or an
exchange of network components is required.
The CPU interrupts processing of the user program and processes the diagnostics block OB82.
The event which led to the triggering of the maintenance event is entered in the start
information of the OB82.
System alarms in STEP 7 (TIA Portal)
The maintenance information is generated in STEP 7 (TIA Portal) with the following system
alarms:
• Maintenance demanded - symbolized for each port by a wrench (on a yellow background)
in the device view or in the hardware configuration.
You can find additional information in the STEP 7 online help.
