The potential of video as a tool for process monitoring

摘要

Steve Rubin, president of Longwatch, discusses an emerging trend in HMI/SCADA: embedding video into an HMI screen, so operators can see what is happening in a process plant, along an assembly line or in remote areas. Today, there are two primary ways to monitor a process: in person, by walking around the plant, or from a control room via an HMI screen. But there is a third way: watching the process via camera monitors that put images directly on the HMI screen or onto a mobile phone or PDA. That way, you don't have to wonder what's happening at the process unit. You can see it.
