The shared memory can be used to exchange data within a target system when no direct communication is possible, e.g. the data exchange with an external visualization. How to create this shared memory and how to read and write to it is shown in this example.
This example is now available for you in CODESYS Forge.

The software package “IIoT Libraries SL” contains libraries for “IIoT communication” and libraries for reading and writing of data structures.

This example shows several possibilities of writing and reading files as well as working with directories. Synchronous and asynchronous function calls are used.

This sample project demonstrates how to transfer files between a CODESYS PLC and the CODESYS web visualization.

The ControlSphere Parameter and Persistence Service Library (CPP) provides an optimized means to store and retrieve variable values to and from well-formatted, human-readable data files. This library provides numerous advantages over the Retain/Persist, Recipes, and Parameters features built-into the CODESYS IDE, particularly in object-based design. Once a Function Block implements the CPP Library, the parameter, persistent, and recipe data for each instance are automatically managed – there are no lists to be created or maintained. The files(s) created by the CPP Library may be edited in a spreadsheet editor and/or moved to other systems to duplicate the persistent, parameter, or recipe values on those systems. This library includes a demo project.

This Library allows you to connect your CODESYS v3.5 application to a MySQL-Sever database to read and write data from it.

Without purchasing a license (just download) the MySQL Library SL runs for 30 minutes without functional limitations and disconnects automatically (demo).

This example shows how to read and write IDN”s with ServoDrive over EtherCAT. Another example shows how to read and write SDO”s with CAN over EtherCAT as well as downloading a firmware file with File over EtherCAT.

The CODESYS PlugIn “Simulink PLC Coder™ Import” makes it easy to import files and update components from Simulink PLC Coder™.

This example shows how to use the serial port. Therefore the communication of two ports with each other is implemented. The first one writes a string of characters, which is read by the second one.
