Description
It provides the information and data reported from a piece of equipment for those DataItem entities defined with a category,DataItem property of SAMPLE in the MTConnectDevices Response Documentresponse document published by an MTConnect Agent in response to a probe request..
Sample MUST always be reported in float.
Figure Sample Example shows Sample type examples. It also shows an example for when the result is not available (dataItemId=cspeed).
Note: See sample-example for the XML representation of the same example.
