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
Global Data Space data types configuration Configuration with PLCnext Engineer You can configure the GDS by connecting IN and OUT ports of programs with the PLCnext Engineer software (see Importing libraries into PLCnext Engineer). In PLCnext Engineer, select the desired use as an IN or OUT port in the Data… 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
Execution and Synchronization Manager (ESM) PLCnext Technology also features task handling. The ESM performs task handling, monitoring and chronological sequencing of programs from different programming languages. Each processor core of a controller is managed by one ESM. One ESM is therefore assigned to one processor core. If a controller… 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
Global Data Space (GDS) The GDS enables communication relationships and data exchange between tasks and programs that were created in different programming languages. The GDS also ensures that inconsistencies as shown in the following example are prevented: While tasks are being processed and data is being exchanged… 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
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
Netload Limiter Available for these devices: AXC F 1152 and AXC F 2152 from 2022.0 LTS AXC F 3152 from 2020.6 RFC 4072S from 2019.9 With the Netload Limiter, PLCnext Control devices offer an option to limit the CPU load caused by received Ethernet telegrams. During normal operation, an increased amount of Ethernet telegrams may occur for a short time. Read More
