Remote debugging of C# code Works for PLCnext Control devices running firmware 2019.0 LTS up to 2022.9 – for newer firmware see Remote debugging from 2023 Because PLCnext Technology includes an implementation of eCLR, you have the option to establish a C# remote session on a PLCnext Control. This topic describes the basic steps needed for setting… Read More
Managing SDKs for C++ programming A Solution Development Kit (SDK) contains all of the important toolchains and libraries required for creating a C++ program for a specific PLCnext Control type. Compatibility: SDKs are specific not only to devices but also to firmware releases and to the operating system… Read More
Required installations for C# programming Valid from toolchain 2021.6 Mandatory installations In order to develop C# functions, function blocks, and programs and use them in a PLCnext Technology real-time application, the following installations are required. PLCnext Engineer automation engineering software The PLCnext Engineer software suite is required… Read More
Working with the SecurityFramework For PLCnext Technology Toolchain 2025.0 and 2025.6 The PLCnext Engineer software suite has implemented from its 2025.0 releases on a new security feature which provides an option to check libraries for trusted signatures. This feature can also be addressed with libraries developed by means of an IDE because the PLCnext Technology Toolchain now contains… Read More
Supported functions for C# programming C# language functions Types All the integrated types are supported, except for decimal. Type system namespaces, structs, classes, interfaces, enumerations, nested types indexers, properties, operations events, delegates, MultiCastDelegates arrays constructors, static constructors, destructors (finalizers)… Read More
Installing IDE plug-ins for PLCnext Technology In high-level language programming, the common workbench is equipped with a specialized tool for smooth and quick workflows. Well known Integrated Development Environment (IDE) tools are Visual Studio® (available for Windows®) or Eclipse® (available for Windows® and Linux®). As part of the PLCnext toolchain, Phoenix Contact offers an Eclipse®… Read More
Real-time programming in C# and the eCLR To develop real-time critical function blocks (FB), libraries and applications (apps) using C# and the .Net™ framework of the eCLR, certain fundamental aspects must be considered during development. Note: This guideline including its software examples is provided “as is”, without… Read More
Remote debugging of C# code Works for PLCnext Control devices running firmware 2023.0 LTS or newer – for former firmware see Remote debugging pre-2023 Because PLCnext Technology includes an implementation of eCLR, you have the option to establish a C# remote session on a PLCnext Control. This topic describes the basic steps needed for setting… Read More
How C# fits into PLCnext Technology Here’s a short overview to the key concept before starting your first C# programming session. C# programming in PLCnext Technology is based on the embedded Common Language Runtime (eCLR) by ProConOS. This runtime system is able to transform both standard hardware and specific… Read More
Referenceable libraries in the System namespace The PLCnext Technology programming system for C# needs referenced libraries which are specifically built for the eCLR runtime. For this, we introduced our own framework (similar to .NET framework) and the eCLR base class libraries. This approach takes care that it’s always downward compatible: libraries… Read More
