CODESYS Control Extension Package :

Overview The CODESYS Control Extension Package provides many different options and interfaces to connect your own programs to the Linux runtime system and the IEC application. This allows you, for exa

Security Mechanisms The extension API provides comprehensive options to influence the runtime system. As a result, the user has to pay attention to necessary security measures. For CODESYS Control Ext

External Event Task The "External event task" mechanism can be used to trigger a task via an external event. "Unix Domain Sockets" are used for process separation. The corresponding socket file is loc

Event Mechanism The runtime system uses "events" to communicate events such as the Start/Stop/Reset of the PLC, the occurrence of an exception, and so on. With the "event mechanism", it is possible to

Access to the PLC Shell The Extension API enables external access to the PLC shell. For this function, a "Unix Domain Socket" is used, which the runtime system uses to receive incoming commands and se

START/STOP Switch The START/STOP switch represents a physical switch which can be used to set the PLC to the Start or Stop state. This mechanism is active if the file /var/run/codesysextension/runstop

Calling an External Function This mechanism can be used to call an external function in an IEC application via a Unix Domain Socket. This allows you to create your own functionalities. At the same tim

Linking Your Own I/Os With this functionality, local I/Os can be connected to a controller and used from the IEC application. Editing the device description In the provided example C:\Users\<user>\COD

Retain Data in Shared Memory Some products do not include an automatic connection of retain data from the application in the controller (due to a lack of generally valid storage options). However, the
