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
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
Redundancy-specific system variables Available for RFC 4072R from 2022.0 LTS In addition to the general PLCnext Technology system variables, the following system variables are available for operating a redundant system of controllers. Information on the redundant control system Redundancy role The LOCAL_RDNCY_INFO system variable is organized as a data structure. Read More
System variables – ESM tasks and HMI clients ESM task handling Available for AXC F x152, RFC 4072S, RFC 4072R Programs and program parts are treated as tasks in PLCnext Engineer. Individual tasks are coordinated and processed in the Execution and Synchronization Manager (ESM). The ESM_DATA system variable can be used to retrieve… Read More
ACF (Application Component Framework) The ACF (Application Component Framework) is the foundation for the PLCnext Technology platform architecture. The ACF is a framework that enables component-based platform development and the configurative composition of the firmware for the devices. It can configuratively distribute the firmware to one or more processes. The… Read More
