PLC Programming

Overview of CoDeSys Functions...
You can use the flow control to check which program lines have been run.
A Log records operations, user actions and internal processes during an online session in a
chronological order.
If activated in the target settings the Sampling Trace allows you to trace and display the actual
course of variables over an extended period of time.
Also a target specific function is the PLC Browser which can serve to request certain information from
the PLC.
Once the project has been set up and tested, it can be loaded down to the hardware and tested as
well. The same online functions as you used with the simulation will be available.
Additional CoDeSys Features
The entire project can be documented or exported to a text file at any time.
For communication purposes CoDeSys has a symbolic interface and a DDE interface. A Gateway
Server plus OPC Server and DDE Server are components of the CoDeSys-standard installation
packet.
Using the appropriate target settings, which can be loaded with the aid of a target file (Target
Support Package) allows to load the same CoDeSys project to various target systems.
Network global variables and a Parameter Manager might be available, if activated by the current
target settings, for data exchange within a network of controllers.
ENI: The 'Engineering Interface' can be used to access any desired source code management
program via the ENI Server, which is running as an independent process. CoDeSys POUs and
compile files can be filed in that data base and are by that accessible also by other clients of the ENI
Server. This allows multi user operation during the work on a CoDeSys project, it provides a common
data pool for different tools besides CoDeSys and it makes possible a version management.
Tools: This functionality also is target dependent and allows to start target-specific executable files in
a CoDeSys project. Besides that files can be defined, which should be loaded to the controller.
Connections to external tools can be pre-defined in the target file or/and inserted in the project
Resource tree.
A CoDeSys visualization can be processed target specifically to be available as Web-Visualization
and/or Target-Visualization. This allows to run and view the visualization via Internet or on a PLCmonitor.
SoftMotion: Diese Funktionalität ist eine Art Basis-Werkzeugkasten zum Realisieren von
Bewegungen – von einfachen Einachs- über Kurvenscheiben- bis hin zu komplexen Bewegungen in
mehreren Dimensionen unter der Entwicklungsumgebung von CoDeSys. Die gesamte Programmlogik
wird im SPS-Programm behandelt und nur die reine Bewegungsinformation in Bibliotheksbausteinen
abgearbeitet. SoftMotion erfordert eine eigene Lizenz und muss vom Zielsystem unterstützt werden.
