Compiler Error C0586

Message: Missing initialization for generic variable '{0}'

Possible error cause: Generic function blocks must be instantiated with parameters for all generic variables. A partial specification is not permitted and will result in an error.

Error correction: Specify a complete parameter passing so that a parameter is listed (as a value or as an expression) for each generic variable.

Example of the error

inst : POU2<(const_1 := 12)>;

Message:

Missing initialization for generic variable 'inst'

Correct code:

inst : POU<12, 12>; //implicit assignments

inst2 : POU2<(const_1 := 12), (const_2 := 12)>; //explicit assignments
