TIME-STAMPING OF INDUSTRIAL CLOUD DATA FOR SYNCHRONIZATION

摘要

A cloud-capable industrial device that provides time-stamped industrial data to a cloud platform is provided. The industrial device collects or generates industrial data in connection with monitoring and/or controlling an automation system, and includes a cloud interface that couples the industrial device to one or more cloud-based services running on a cloud platform. The industrial device can apply time stamps to respective items of industrial data reflecting a time that the data was measured or generated prior to providing the data to the cloud platform. To accurately reflect temporal relationships between data sets provided to the cloud platform from different locations and time zones, the industrial device can synchronize its internal clock with a clock associated with the cloud platform.
