Live Chart with EtherCAT
Live chart is commonly needed for process monitoring. EtherCAT's fast data rate makes it possible to have very dynamic live chartiing capability. In one of recent project, I tried the live chart from a very simple QT live charting mechanism. The data used for live chart is exchanged through ADS communication interface. The chart itself is realized from QT's standard line chart. It is surprisingly easy to do this with both tools, simple and yet powerful. This opens a lot potential for industrial application, environment mointoring and control, process mointoring and control, parallel user interface etc. The best part is that it is no longer need to have the typical bulky HMI hardware and proprietary programming for each HMI. Porting this to hand hold device will enable a large field of applications.
