About the library

Library is created to provide the functions of different control algorithms and can be used in programmable logic controllers (PLCs) based on OpenSCADA for construction control schemes. The library is not static, but based on the module JavaLikeCalc, allowing to create calculations on the Java-like language.


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


To connect the library to the project of the OpenSCADA station it is possible by downloading the attached file of the database, placing it in in the database directory of the station's project and creating the database object for the DB module "SQLite", indicating the database file in the configuration.

1 The library structure

In his part the library contains several functions often demanded by creating regulatory schemes. The functions' names and its parameters are available in three languages: English, Russian and Ukrainian.

PID (unified) (pidUnif)

Description: 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.
