Alarms; Diagnostics Alarms - Siemens SIMATIC ET 200eco PN M12-L Equipment Manual

5.2.3

Alarms

The IO-Link master can generate diagnostic alarms of the type (severity) "Diagnostics" or
"Maintenance" on behalf of the IO-Link device or the IO-Link port.
• Alarms of the "Diagnostics" type indicate a malfunction of the IO-Link device / port and
should be corrected immediately.
• Alarms of the "Maintenance" type indicate a maintenance demand. The aim is to detect
and eliminate potential faults at an early stage, even before functionality is impaired.
• Hardware interrupt events signal the corresponding process states on the IO-Link device
(e.g. limit exceeded)

Diagnostics alarms

IO-Link master error types
All IO-Link events of the type Error generated by the IO-Link device or port are mapped to the
PROFINET diagnostics alarm of the type (severity) "Diagnosis" of the assigned submodule.
IO-Link device diagnostics
The IO-Link master generates PROFINET channel diagnostics (CET, ECET) from the IO-Link
events of an IO-Link device according to the following mapping regulations:
In the "IO-Link Device Diagnostics - Page 1" (CET 0x9500
range 0x0000 - 0x7FFF
ECET
In the "IO-Link Device Diagnostics - Page 2" (CET 0x9501
range 0x8000 - 0xFFFF

IO-Link port diagnostics
The IO-Link master generates channel diagnostics for each port. The port-specific channel
diagnostics are shown in the port diagnostics (CET 0x9502
