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
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
