Evaluating interrupts with IO controller
The IO-Link Master 4 IO-L 4×M12 supports the following interrupts:
• Diagnostic interrupts (at IO-Link Master / at submodule port)
• Hardware interrupts (at submodule port)
• Pull/plug interrupts (at submodule port)
• Maintenance events (at submodule port)
In the case of an interrupt, the CPU of the IO controller automatically calls the interrupt OBs.
The OB number and the start information provide you with information about the cause and
class of the error.
You can obtain detailed information on the error event in the error OB with the "RALRM"
instruction (read supplementary interrupt information).
System diagnostics
In STEP 7 (TIA Portal), the innovated system diagnostics is available for the devices of the
S7-1500 automation system (IO controller CPU S7-1500) and ET 200eco PN (IO device).
Alarms are made available on the display of the S7-1500 CPU, the CPU Web server and the
HMI device.
More information on system diagnostics is available in the Diagnostics function manual on
the Internet (https://support.industry.siemens.com/cs/ww/en/view/59192926).
11.2.5.1
Triggering of a diagnostic interrupt
Introduction
All IO-Link events of the type error, which the IO-Link Device generates, as well as problems
and errors at the IO-Link port (for example Diag: Missing 2L+), are mapped to the diagnostic
interrupts for the assigned submodule.
Triggering of a diagnostic interrupt
If you have assigned the parameters for the IO-Link master accordingly, this triggers a
diagnostic interrupt for an incoming or outgoing event of the IO-Link device.
The CPU interrupts the processing of the user program and processes the diagnostic interrupt
OB (OB 82). The event that led to the triggering of the interrupt is entered in the start
information of the diagnostic interrupt OB.
11.2.5.2
Triggering a hardware interrupt
Introduction
All IO-Link events of the type notification which the IO-Link device generates are mapped to
the hardware interrupts of the assigned submodule.
