What are the software highly involved in SCADA?

I dont think all the softwares can be named in one go. 

Major Players in this field are :

1- Rockwell and its SCADA solution is Factory Talk View Solution 

2- Invensys - Woderware Intouch and Archestra Solution (System Platform)

3- Siemens - WinCC

4- Schnieder - Vijeo Citect

5- Honeywell - Experion

Then there are other companies such as ABB, Emerson, Mitsibushi etc. 

There is no limit to knowledge. 

Thanks
