Interrupts
Introduction
The I/O device triggers interrupts as a reaction to specific errors. Interrupts are evaluated
based on the I/O controller used.
Evaluating interrupts with I/O controllers
The ET 200SP distributed I/O system supports the following interrupts:
● Diagnostic error interrupts
● Hardware interrupts
● Pull/plug interrupts
● Maintenance events
In the event of an interrupt, interrupt OBs are automatically called in the CPU of the IO
controller.
Information on the cause and class of the error is already available, based on the OB
number and start information.
Detailed information on the error event can be obtained in the error OB using the instruction
"RALRM" (read additional interrupt information).
