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
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 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 List editor of… 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
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
Diagnostic log file Output.log The Output.log diagnostic log file contains status information, warnings, error messages, and debugging messages. It offers a lot information of the boot up and operation of a controller of the PLCnext family. It is a good compromise between information and system performance. You will find… Read More
Retain variables in Extended Retain Handling General retain memory concept Traditionally a PLC offers two types of memory: Volatile memory: values are lost on power down (usual RAM). Retain memory: values are kept during power down so these values can be restored on power return. Read More
PLCnext Technology naming conventions When designating PLCnext Technology components, please observe the following conventions. Correct functioning of your components can only be ensured if you adhere to the following specifications. GDS ports A designation… may not start with a number must consist of at least two… Read More
Netload Limiter Available for: 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. However,… Read More
Function extensions For a thorough distinction between the Function extensions for internal processes Users can add their own function extensions to PLCnext Technology. The System Manager loads and monitors these function extensions. All available PLCnext Technology APIs can be used: RSC (Remote Service Call): Each component… Read More
