Paragraph:

Category: Issue for edition 2 of this part

Issue: In some case, it is necessary to describe discrete values that can be set for an ASG. See for instance HzRtg in 9-2LE. It is defined as supporting 16,7; 25; 50; 60.
There is no way to specify the supported values with means of SCL.

Proposal: Add a way to describe a choice of value for the DAI/DA

This is not a question of SCL, but a question of the HzRtg definition. If HzRtg would have been defined as Enum, SCL would allow to have it as Enum with exactly above four values. Instead it is defined as Float value, and therefore syntactically every float value is allowed, and the application has to check on meaningfull values, NOT SCL. If this is an issue, it must be solved in 7-4.	04 Aug 06	red		ABB Wolfgang Wimmer
