This document specifies the communication schema designed to provide mobile machinery status data from a telematics provider's server to customer applications via the Internet. The data is collected from a mobile machine using telematics data-logging equipment and stored on a telematics provider's server. This document describes the communications records used to request data from the server and the responses from the server containing specified data elements to be used in the analysis of machine performance and machine management status related with operation and/or maintenance. It is applicable to self-propelled earth-moving machinery as defined in ISO 6165 and mobile road construction machinery as defined in ISO 22242 equipped with location and time instrumentation. It is not applicable to the on-board data collection, on-board communication protocol (e.g. CANbus) or wireless transmission of the mobile machinery data to the telematics provider's server after the data have been collected at the data logger. See Figure 1.
