The controller will never send a request for an _CLEARED Status Type.

The controller will send a GET STATUS_MESSAGES Status Type ERROR. The responder can then return status messages with Status Type ERROR and ERROR_CLEARED.

Request:
GET STATUS_MESSAGES ERROR

Response:
ERROR: Dimmer Room Flood
ERROR: Low Line Voltage
ERROR: Ground Fault Trip
ERROR_CLEARED: Dimmer on fire
ERROR_CLEARED: Dimmer Rack Overtemp

To put it colloquially, the controller asks: "Tell me about your error conditions". The responder then replies "The following 3 error conditions have occurred, and 2 error conditions I reported earlier are no longer present.

The controller will not send:
GET STATUS_MESSAGES ERROR_CLEARED


Edit:
If your responder receives a request for Status Type _CLEARED, you should respond with "NR_DATA_OUT_OF_RANGE".

Many thanks, Eric. More of the careful interpretation of table 10-1...
