DataHub use case
A wood fence manufacturer in North America used OPC as the data communication protocol to connect its Manufacturing Execution System (MES) to its manufacturing equipment. Wanting to get the most out of their system, the engineering team looked to see if there was a way to perform calculations on the real-time data flowing from the OPC server to their MES.
A friend told them about data hub and its built-in scripting capability. They found it easy to set up a separate OPC connection from the OPC server to their MES, with the DataHub plugged into the data path. By running several DataHub scripts, they can analyze the numbers on the fly and feed the results into the MES in real time. The result is that the MES can simultaneously work with raw data and live analysis on that data.
This initial success with the DataHub sparked other ideas. They wrote another script to control the run and idle settings of plant equipment from the MES. Using the Bridging feature, they were able to replicate and rename entire sets of data tags. And they also use the Email/SMS function to send email messages to plant operators with dynamic content related to system events, which gives operators greater mobility and reduces their workload.
