FLibComplex1 Complex1 functions 1.2 GPL2 en,uk,ru,de x86,x86_64,ARM Special Roman Savochenko

Provides a library of the functions of compatibility with SCADA Complex 1 of the firm DIYA Ltd.

The module provides OpenSCADA for a static library of compatibility functions with SCADA Complex1 of the firm SIC "DIYA". These functions were used in Complex1 in the form of algoblocks to create in-system computations based on the virtual controller. Providing the library of these functions allows the transfer of computational algorithms from Complex1.

To address the functions of the library you can use the static call address Special.FLibComplex1.{Func}() or dynamic SYS.Special.FLibComplex1["{Func}"].call(), SYS.Special.FLibComplex1.{Func}(). Where {Func} — function identifier in the library.

Below is a description of each library function.
