Semantic Error (SEM1203): Invalid value '...' of parameter '...' of pragma '...'.

In the definition of a user-defined data type, a pragma is used with an invalid syntax. You have assigned an invalid value to an optional pragma parameter, for example, due to a wrong data type.

Make sure that the value assigned to the optional pragma parameter has the expected data type.

Error example: The Low alarm limit expects a numeric value. Instead, a BOOL value is assigned.
