I'm SCADA beginner. Never use before for the SCADA software was mention by @arj3090. Good to know and I would like to try. Thanks!
My first SCADA project was developed by using ECAVA IGX Web SCADA. Ecava IGX has impressed me when use it on first time. It's easy to use and I can view the mimic on my smartphone & tablet without install anything at all. Furthermore, the image on mimic is SVG and it won't have image pixelated problem when enlarged.
I will highly recommend to all the SCADA beginner because it's easy to use and do not need spend a lots of time for project development. For the SCADA expert user, you can try on this Ecava IGX Web SCADA to check out how the different with the SCADA software that you used before. Below is the their official website link
