What are the top 5 things you look for in your HMI/SCADA software?

here is my view 1]library available for your industry 2 analysis tools to find faults fast 3]communication speed between plc and scada 4]should have script support to write user defined scripts 5]alarms etc

1) Programming support ( .Net, VBScripts, JScripts etc), Library/Activex Support
2) Graphics Library, Drawing tool
3) Alarms/Event ... ( including System generated for Fault finding )
4) Communication Protocol support.
5) User Interface to finish the developement Quickly

These are my wish list apart from "OBVIOUS" features that are available in any SCADA

1.Easy to follow documentation for Instrumentation Professional
I find documentation is voluminous and not user friendly
2.Utility to tune and improve PLC to SCADA communication baud rates
For improving point update rates, we have to look into different areas for optimization. I wish a single point adjustments
3.Utility to check and confirm whether computer resources are sufficient for SCADA operation
4.Project templates for beginners for quick completion of projects
Some examples are Water,Waste Water,Boiler.....
5.OS compatibility info
I find that service pack x shall be used for invoking this function...after working long in a project

Kindest Regards

Thank you all so far for your comments, we at Mobiform Software have a inexpensive and very powerful HMI/SCADA software and are trying to make sure we include all the importatn features end users want. www.statusvision.com

scripting is important... at the client level for graphics animations and that kind of stuff but also at the server level for programming tags related tasks.

This is my list:

- OPC connectivity
- Integrated database of points (tags) with user-friendly configuration interface
- Programming tools for advanced scripts
- Supervision/Alarms/Historical Trend redundancy features
- Configuration reusability ( templates, faceplates, tuning & trend standard screens, screen objects, etc )
