Debugging VBScript in InduSoft Web Studio Projects

  1. 1. Established in US in 1997 Since Sep, 2013: an Invensys Company! Pioneer in industry: First HMI/SCADA package for Microsoft Windows CE Web solution and XML integration in HMI/SCADA Patent for database connectivity Multi-touch support and HTML5 integration Certifications:
  2. 2. Brief Intro Why VBScript?: It is a quite well known high-level programming language Simple, Flexible and Standard Runs on Windows Embedded OS and Internet Explorer It is similar to VBA, which is also used on other MS Applications such as the MS-Office suite Which IWS interfaces support VBScript?: Script Task, Global Procedures, Startup Script, Screen Script, Graphics Script, Command animation property, ActiveX and .Net controls Methods  Support to Built-in IWS functions and tags on VBScript Environment
  3. 3. VBScript Cool Features!: Use of Variables on the Script! Save on tag count!!! Intellisense: auto-complete (less typing, more doing) Create your own Functions and Sub-routines  Find on the Internet scripts with examples on how to do things that you are not sure how to do!
  4. 4. Database Spy:  It works to debug project running on the local machine or in remote ones  Used to see and load values into tags  It can also execute Built-in Functions or call VBScript procedures Sub-routines  NEW!!! Support to seeing VBScript variables values and functions status
  5. 5. Output Window / LogWin:  Helps to debug almost all IWS tasks, such as Comm Drivers, OPC messages, Database transactions, Screens load time, Log tag changes, and so forth  Like the DBSpy, it works for both Local and Remote projects  TRACE messages has been the biggest friend on debugging scripts until now  It can save Log Files
  6. 6. What can be debugged?  Global Procedures  Graphics Script  Scripts from the Script task and Startup Script  Screen Script and Graphics Script What is not supported yet?  Command Properties on screen objects  ActiveX and .Net Controls Methods
  7. 7. The new DEBUG tab  It only appears when a supported VBScript interface is open  Allows the user to select between Debugging the Viewer module or the Background tasks  It is where the user controls the debug execution by starting, stopping, going to the break points, Stepping Into a function, Over and Out as well.
  8. 8. Break Points  Used to identify important sections that you want to focus your debugging process  Temporarily suspends the script execution on that point  During that break time, the user can check variable values, execution states, and be prepared for the next steps
  9. 9. Stepping through  Once the execution in in Break mode, the user can:  Step Into: advances a single step forward  Step Over: advances a step on the main Script, not stepping into function calls  Step Out: if the main script called a function and is debugging there, this command will finish the execution and return to the main script
  10. 10. Database Spy  Once the execution in in Break mode, the Database Spy can help the user see:  Locals: Local Variables values  Stack Frame: Shows which VBScript interfaces are currently under Debug mode  Tasks Frame: shows the Runtime tasks states during the Break
