Events
20-COMM-M Modbus/TCP Adapter User Manual
Publication 20COMM-UM014C-EN-P
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 is put into the
event queue. You can view the event queue using an LCD PowerFlex
7-Class HIM, DriveExplorer (2.01 or higher) software, DriveExecutive
(1.01 or higher) software or other clients using the DPI Fault object.
The event queue can contain up to 32 entries. Eventually the event queue
will become full, since its contents are retained through adapter resets. At
that point, a new entry replaces the oldest entry. Only an event queue clear
operation or adapter power cycle will clear the event queue contents.
Resetting the adapter to defaults has no effect on the event queue.
