Tricorder vs locad6/15/2023 ![]() ![]() Add in some condition monitoring and device diagnostic software from various vendors, and you have the equivalent of Mr. For example, Indusoft’s Web Studio HMI/SCADA software takes up 3 MB of memory, MRO’s Maximo remote software requires 48 MB, and the Foundation fieldbus communicator software from Emerson Process Management takes up 32 MB. With as much as 2 GB, “Today’s handheld devices have enough memory and processor speed to run HMI/SCADA software,” says Roland. All you need is a handheld with enough memory to support all the software, and HMI/SCADA software that will run on the diskless PDA and gather all the necessary real-time information. This includes HMI, SCADA, data logging, vibration analysis, equipment diagnostics and, of course, CMMS functions. It’s just not all being done in the same device - not yet, anyway.Īccording to Ernie Roland, president of InduSoft ( almost anything you can do with a conventional industrial PC can be done with a handheld device. But everything described above is being done today with handhelds. You do all this in about 15 minutes, without leaving the pump, all from the keyboard on your handheld. Next, plug that data into a diagnostic package and discover that a bearing is going bad, a motor is failing or there’s a clog building up downstream.ĭownload the appropriate repair procedures for such a pending failure, and make up a work order for a maintenance tech to fix the machine before it breaks. Then, switch over to the handheld’s HMI/SCADA software, bring up a trend plot from the plant’s control system and check all the critical operating values, such as current draw, vibration data, rpm, flow, etc. Using your handheld PDA, smart phone, Blackberry or portable PC, you scan the bar code to identify the pump, check to see if the CMMS has detected any problems from condition monitors, call up the pump’s recent service history, and see what the last tech said in the work order. For example, let’s say your experienced ear detects a slight change in the familiar sound of a motor-driven pump. Imagine being able to walk around the plant on an inspection route, spot a problem with equipment, and solve it right there on the spot.
