Interrupts

Introduction
The I/O device generates interrupts as a reaction to specific error events. Interrupts are
evaluated based on the I/O controller used.
Evaluating interrupts with I/O controllers
The ET 200MP distributed I/O system supports the following interrupts:
● Diagnostic interrupts
● Hardware interrupts
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).
System diagnostics
In STEP 7 (TIA Portal) as of V14, innovative system diagnostics is available for devices of
the S7-1500 automation system and ET 200MP. Independently of the cyclical user program,
alarms are made available on the display of the S7-1500 CPU, to the S7-1500 CPU web
server, to the HMI device and in STEP 7.
For additional information on the system diagnostics, refer to the System Diagnostics
function manual. (https://support.industry.siemens.com/cs/ww/en/view/59192926).

Meaning
There is no Ethernet connection between the
PROFINET interface of your PROFINET device and a
communication partner (e.g. IO controller).
There is an Ethernet connection between the
PROFINET interface of your PROFINET device and a
communication partner (e.g., IO controller).
There is active data traffic (sending/receiving) via the
Ethernet connection.
"Node flash test" is performed. (The LEDs
RUN/ERROR/MAINT are also flashing.)
Interrupts and diagnostic, error, and system alarms
Check whether the bus cable to the
switch/IO controller is interrupted.
