Description

It provides the information and data reported from a piece of equipment for those DataItem entities defined with a category,DataItem property of CONDITION in the MTConnectDevices Response Documentresponse document published by an MTConnect Agent in response to a probe request..

Figure Condition Example shows Condition type examples for various state: Normal (dataItemId = path_system) and Warning (dataItemId = logic_cond). It also shows an example for when the state is not available (dataItemId = cont_system).

Note: See condition-example for the XML representation of the same example.

The following Section Value Properties of Condition lists the additional and/or updated attributes for Condition.
