Fault and Status Reporting

The IO-Link master module reports fault and status data along with channel data. Fault and status data is reported in the following ways:
  • Fault and status bits in the input data tags
  • Studio 5000 Logix Designer application
  • Module status indicators
Fault and Status Tags – IO-Link Master Module
Data Type
Tag Name
Triggering Event That Sets the Tag
Fault
ConnectionFaulted
The controller loses its connection to the module.
TIP:
ConnectionFaulted
 tag provides module-wide data and affects all channels simultaneously.
Status
RunMode
The module is in Run Mode.
DiagnosticActive
Indicates if any diagnostics are active or if the prognostics threshold is reached.
DiagnosticSequenceCount
The count increments each time a diagnostic condition is detected or removed.
You can monitor this count during module operation and check the channel diagnostics when the count value changes.
Fault Tags – I/O Channels
Data Type
Tag Name
Triggering Event That Sets the Tag
Fault
Ptxx.Fault
The channel data quality is bad.
Counterxx.Fault
The counter data quality is bad.
IOLinkxx.Fault
The IO-Link data quality is bad.
We recommend that you monitor the tags in your program to make sure that the application is operating as expected.
IMPORTANT: Once the condition that causes the
Fault
 or
Uncertain
 tag to change to 1 is removed, the tag automatically resets to 0. The Studio 5000 Logix Designer application controls the tags. You cannot change the status of the tags.
Remember that in some system configurations, the tag is not reset immediately after the condition is removed. The tag typically resets after a short delay.
