The ControlSphere Parameter and Persistence Service Library (CPP) provides an optimized means to store and retrieve variable values to and from well-formatted, human-readable data files. This library provides numerous advantages over the Retain/Persist, Recipes, and Parameters features built-into the CODESYS IDE, particularly in object-based design. Once a Function Block implements the CPP Library, the parameter, persistent, and recipe data for each instance are automatically managed – there are no lists to be created or maintained. The files(s) created by the CPP Library may be edited in a spreadsheet editor and/or moved to other systems to duplicate the persistent, parameter, or recipe values on those systems. This library includes a demo project.

The framework “SQL4CODESYS” allows direct communication between CODESYS controls and databases. With the database, large amounts of data can be efficiently managed, which opens up many new possibilities (detailed logging of information, flexible production by retrieving production parameters, recording of process values during production for traceability, interface to ERP and order management systems, …).

Compared to systems which communicate via an OPC interface, the software architecture is considerably simpler and more powerful with this approach!

The framework has been developed and can be used for a variety of databases, PLC and robot controls.
