Managing components PLCnext Technology is based on components that are included via the IComponentInterface interface (see IComponent and IProgram). ACF – Application Component Framework The Application Component Framework (ACF) is a part of the System Manager and manages the function extensions. The ACF is a framework that enables… Read More
plcnextapp log file The plcnextapp tool manages apps, e.g. the mounting and unmounting. The plcnextapp tool is called by the AppManager. The plcnextapp.log file is used to record status and error messages that are issued by the plcnextapp tool. You will find the file by default on your controller under… Read More
Service Components – Overview Service Components are built-in benefits for programmers that come with the PLCnext Runtime System. Depending on the firmware release on your PLCnext Control, the set of features can be different. Find a detailed description to every service component via the respective link in the first column. Built-in communication… Read More

System monitoring Available from firmware version 2025.0 The system monitoring is a library that consists of the components system watchdog and system monitor. The firmware component system monitor has been released with firmware version 2025.0 and extends the system watchdog with diagnostic options. It monitors system critical parameters like RAM… Read More
Configuration files Although PLCnext Engineer is the recommended tool you can load programs and program instances onto the controller even without using the PLCnext Engineer. This also applies to files in .pcwlx libraries programmed in C++ by using the Eclipse® IDE with PLCnext Technology Add-in, or Visual Studio® with PLCnext Technology Extension, or the PLCnext CLI. But before transferring… Read More
System Manager and PLC Manager System Manager PLCnext Technology is by definition an open platform. This means that as a user you can integrate your own components and programs. During firmware startup, the System Manager ensures that all integrated components and programs are configured and started in the correct… Read More
Core components of the PLCnext Technology PLCnext Technology is an open firmware platform executed on a Linux operating system with real-time patch. Different firmware components forming the core functions are called core components. These core components are a fixed part of the PLCnext Technology firmware. They cannot be modified. The core components… Read More
Function extensions A main feature of PLCnext Technology is the modular extensibility on user’s side, for example by means of so-called “function extensions”. How these function extensions differ from apps, see C++ programming on PLCnext Technology Function extensions for internal processes Users can add their own function extensions to PLCnext Technology. The… Read More
