Viewing Adapter Diagnostic
Items If you encounter unexpected communications problems, the adapter’s diagnostic
items may help you or Rockwell Automation personnel troubleshoot the
problem. The diagnostic parameters for the adapter can be viewed using the
PowerFlex 22-HIM-A3/-C2S HIM or Connected Components Workbench
software.
The adapter’s diagnostic items cannot be viewed in Multi-drive mode.
Viewing and Clearing Events The adapter has an event queue to record significant events that occur in the
operation of the adapter. When such an event occurs, an entry consisting of the
event’s numeric code and a timestamp is put into the event queue. You can view
the event queue using the PowerFlex 22-HIM-A3/-C2S HIM or Connected
Components Workbench software.
The event queue can contain up to 32 entries, which are stored in an EEPROM
chip—making the event queue nonvolatile. Eventually the event queue will
become full, since its contents are retained through adapter power cycles and
resets. At that point, a new entry replaces the oldest entry. Only an event queue
clear operation will clear the event queue contents.
