Monitoring plant performance from home through a web interface
A Canadian chemical plant uses the OPC DataHub to provide plant engineers with the ability to visit the company web site and view live performance data. So now, when the engineer gets a call at home, he can open up his web browser, log-in to the company site and review the latest data before making recommendations, or taking preventative action by changing process variables through the same web interface. No need to drive out to the plant for minor problems and he can react to problems rapidly and with enough information to make informed decisions.
