Structure of a C++ program PLCnext Technology follows an object-oriented approach. The following base classes are relevant for creating a C++ program running on a PLCnext Control. Depending on the functional needs, such a program can be integrated as either ACF component or PLM component. Library LibraryBase class The… Read More
C++ program types on PLCnext Technology Types of C++ programs Depending on the functions you want to create, there are different ways to implement C++ code in PLCnext Technology. C++ real-time applications are deterministically executed in the real-time context (ESM) on a… Read More
C++ programs in PLCnext Technology With PLCnext Technology, you can use programs created with C++ in the real-time context of a PLC along with conventional IEC 61131‑3 programs. To use programs and program parts created in C++ within the scope of PLCnext Technology, Phoenix Contact provides tools and add-ins that help to integrate your… Read More
Datatype Worksheet Datatype worksheets can be deployed with the PLCnext Engineer library and there for being an optional part of the PLM and ACF project types. The plcncli generate config command or in IDE as part of the build process, generates a DataTypes.dt file in the intermediate folder. Each struct,… Read More
PLM (Program Library Manager) The Program Library Manager (PLM) is part of the PLC Manager. It loads and unloads components during the runtime of the PLCnext Technology firmware. The PLM controls the entire service life of the component instance in accordance with the states of the controller and changes of… Read More
Common classes Common classes provide functions that may be helpful for programming. The PLCnext Technology-specific common classes are made available via the PLCnext Technology SDK. With the help of the SDK, it is possible to generate high-level-language programs in C++ for the PLCnext Technology framework. The SDK provides Arp firmware header files… Read More

Features: Connecting ports using the Port Wizard Adding an ACF library version and description Using multiple namespaces Using multiple… Read More
Working with Visual Studio® Valid from toolchain 2021.6 – for former releases see Creating a C++ project with Visual Studio This topic describes the general approach to C++ programming on PLCnext Technology with Microsoft® Visual Studio® IDE using the C++ PLCnext Technology Extension from Phoenix Contact. Of course, you might use also the Eclipse® IDE,… Read More
Working with Eclipse® Valid from toolchain 2021.6 (for former releases see Creating a C++ project with Eclipse) This section describes the general approach to C++ programming on PLCnext Technology with Eclipse® IDE. Note: If preferred, you might as well use Visual Studio® , the other officially supported IDE. Or instead you can rely on… Read More
Advanced use of IComponent and IProgram Using the PLCnext CLI , Eclipse® Add-in or Visual Studio® extension creates the meta configuration files (*.libmeta, *.compmeta, *.progmeta) required for PLCnext Engineer as well as the following functions with a functional implementation during compiling. If you have special requirements that go beyond this, the following descriptions will help you understand the… Read More
