Evaluation of interrupts with PROFINET IO

Triggering of interrupts
The I/O device generates interrupts as a reaction to specific error events. Interrupts are
evaluated depending on the I/O controller used.
Evaluating interrupts using an IO controller
The 3RW44 soft starter with PROFINET communication module supports diagnostic
interrupts.
An interrupt automatically initiates execution of the interrupt OBs in the CPU of the I/O
controller (see the
"Program design".
Information on the cause and class of the error is already available based on the OB number
and start information.
You can obtain detailed information on the error event in the error OB by calling SFB 54
RALRM (read supplementary interrupt information).
