Activate the PLC configuration
The PLC configuration is automatically loaded with the target system. The PLC configuration maps the
contents of the file CR0403.cfg in CODESYS. Like this, the programmer has easy access to
predefined system and error flags, inputs and outputs as well as to the CAN interfaces of the device.
To access the PLC configuration (e.g. CR1080):
► Click on the tab [Resources] in CoDeSys:
► Double-click on [PLC Configuration] in the left column.

Based on the configuration the following is available in the program environment for the user:
• System and error flags
Depending on the application and the application program, these flags must be processed and
evaluated. Access is made via their symbolic names.
• Structure of the inputs and outputs
These can be directly symbolically designated (highly recommended!) in the window [PLC
Configuration] (example → figure below) and are available in the whole project as [Global
Variables].
