Extending the Project Tags datasheet

The Project Tags worksheet can be extended up to 65,488 rows, if necessary.

The datasheet is normally limited to a maximum of 32,721 rows. (This is separate from the maximum size of the project database as a whole, as well as the runtime limit that is set when you select a target platform for a new project.)

To extend the worksheet, edit your project file (project_name.app) to include the following entry:
  [Options]  EnableExtendedTagCount=1  
Doing so, however, brings the following restrictions:
  • Project tags in rows 32,722–65,488 of the worksheet cannot be used as array indices in expressions. That is, in an expression like Abs(numArray[indexTag]), indexTag cannot be in that range of rows. (This restriction does not apply to the VBScript interface.)
  • In a Class worksheet, only the first 32 class members can have alarms. For all class members after the first 32, alarms will not work.

Generally speaking, extending the Project Tags datasheet stretches the capabilities of IWS and should be done only when it’s absolutely necessary. It is better to design your project to conserve tags.
