Introduction
Special module FLibComplex1 provides the OpenSCADA system with the static library of functions compatible with SCADA Complex1 of firm SIC "DIYA". These functions are used in the SCADA system Complex1 in the form of algoblocks to create inner-computings on the virtual controller. Provision of the library of these functions lets to do the transfer of computational algorithms from the system Complex1.
To address the functions of the library you can use 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 the description of each function of the library. For each function it was evaluated the execution time. Measurements were made on the system with the following parameters: Athlon 64 3000 + (ALTLinux 4.0 (32bit)) by measuring the total execution time of the function when you call it 1000 times. Sampling was carried out of the five calculations, rounded to integer. Time is in angle brackets and is measured in microseconds.
