TrakHound DataClient reads MTConnect® streams and sends the data to TrakHound DataServers to be stored.
DataClients communicate with MTConnect using the standard request structure of Probe, Current, and subsequent Sample streams. MTConnect data is then converted into StreamData which is categorized into AgentDefinitions, DeviceDefinitions, DataItemDefinitions, ComponentDefinitions, and SampleData.
By using TCP, the connection also supports SSL(TLS) which can be used to both encrypt data and verify the connection to the DataServer. Certificates are setup on the DataServer and the DataClient is configured to use SSL by setting the UseSSL parameter in the DataClient's configuration.
A Buffer is used to store data that was unsuccessfully sent to the DataServer in the case of a temporary loss of connection. The buffer is composed of multiple csv files. By storing the buffer on the filesystem (as opposed to in memory), this makes the buffer 'non-volatile' and is automatically recovered on power loss. This system insures that data is never lost and allows for easy DataServer maintenance.
