Diagnostic Alarm

Events from IO-Link Master and IO-Link devices are mapped to PROFINET alarms and channel
diagnostics according to the IO-Link on PROFINET Working Document Version 13.4.2015 with some
modifications.
10.3.1

IO-Link Event Mapping Overview

IO-Link events are mapped into PROFINET Alarms and Channel Diagnostics using the following table.
Each appearing IO-Link event (mode Coming) results in adding channel diagnostics. Each
disappearing IO-Link event (mode Going) results in removing channel diagnostics. IO-Link events that
have mode Single will be mapped to the PROFINET process alarm.

Going
In addition, only IO-Link events that have the type of Error or Warning are mapped to PROFINET
channel diagnostics. Type Message IO-Link events are not mapped.
Note: Process alarms are reported as 'Unexpected PROFINET Alarms' in the IO fault table of the PLC.
10.3.2

IO-Link EventCode Mapping

IO-Link events that are generated by IO-Link devices (remote events) are mapped to PROFINET
diagnostics using ChannelErrorType 0x500 and0x501.

For an EventCode that is between 0x0000 and 0x7FFF, ChannelErrorType 0x500 is used. The
EventCode is directly mapped to ExtChannelErrorType.
For an EventCode that is between 0x8000-0xFFFF, ChannelErrorType 0x501 is used. The
EventCode is mapped to ExtChannelErrorType with the MSB set to 0.
For IO-Link events that are generated by IO-Link Master (local events), ChannelErrorType
0x502 is used.
EventCode is directly mapped to ExtChannelErrorType.
