Evaluation of interrupts with PROFIBUS DP

Introduction
Certain errors cause the DP slave to trigger an interrupt.
The M200D PROFIBUS supports the following interrupts:
● Diagnostics interrupts
Evaluating interrupts with the DPV1 master
The CPU of the DP master automatically calls the interrupt OBs after an interrupt was
generated.
For further information, refer to the
programming manual.
Note
The system does not generate any interrupts when M200D PROFIBUS motor starter is
operated with a DPV0 master, or in DPV0 mode (as standard DP slave).
Triggering of a diagnostics interrupt
The module triggers a diagnostics interrupt with "Enable: Diagnostics interrupt" when it
registers incoming or outgoing events, such as a wire break.
The CPU interrupts the user program and executes the diagnostics block OB 82. The
interrupt triggering event will be logged in the start information of OB 82.
