Regulation elements library 1.0 GPLv2 OscadaLibs.db (SQL, GZip) > DAQ.JavaLikeCalc.regEl en, uk, ru Roman Savochenko Regulation elements library of block-schemes of the module DAQ.BlockCalc.
- move to the DAQ-templates after their conception expanding for the internal links (+) and the DAQ.BlockCalc expanding for using the DAQ-templates.

The library is created to provide functions of different control algorithms and it can be used in programmable logic controllers (PLC) based on OpenSCADA for construction control schemes in the module DAQ.BlockCalc. The library is not static, but based on the module JavaLikeCalc, allowing to create calculations on the Java-like language. The functions' names and their parameters are available in languages: English, Ukrainian and mRussian.

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

For connection the library to a project of the OpenSCADA station you can obtain the database file as:

wget http://oscada.org/svn/trunk/OpenSCADA/data/LibsDB/OscadaLibs.sql
sqlite3 -init OscadaLibs.sql OscadaLibs.db .exit

This obtained file next you can place into the project's database directory of the station and create the database object for the DB module "SQLite", registering the database file in the configuration.

1 PID unified (pidUnif)

1.0 GPLv2 * en, uk, ru Roman Savochenko

Composite-unified analog and pulse PID. At the heart of the regulator is core a standard analog PID controller from the library FLibComplex1 and the implementation of the PWM for the pulse part.
