2.3 Programming software
Use the CODESYS V3 pbF programming software to commission and program the controller CECC.
CODESYS V3 pbF offers a user-friendly interface with the following functions:
– Configuration and parameterisation of the CECC using the controller configuration
– Programming in accordance with IEC 61131-3
– Integrated module libraries
– Library Manager for integrating further libraries
– Simulation mode for testing projects on a PC without a PLC
– Integration of a visualisation; configuration using Designer Studio (available separately)
– Documentation using the integrated project documentation function
– Debugging function for testing program sequences, monitoring and changing variables,
troubleshooting
2.3.1 Packages
The associated CECC package is required to use the controller CECC (target system) under CODESYS
V3 pbF. This package enables the system functions of the target system to be accessed with the help of
libraries and contains corresponding information in the form of online Helps. This enables Codesys
functions to be used for the target system or, if necessary, restrict it.
CODESYS V3 pbF is supplied with the CECC package for the controller CECC.
2.3.2 Remanent variables
A maximum of 7,120 bytes are available on the CECC for storing remanent variables. They are
automatically shared based on the variable declaration within the application.
The following sample combinations for distributing the remanent memory are possible:
RETAIN variable PERSISTENT RETAIN variable
7,120 bytes 0 bytes (only if there is no PERSISTENT variable list)
0 bytes 7,076 Byte (44 bytes for identification)
300 bytes 7,076 - 300 bytes = 6,776 bytes (44 bytes for identification)
x bytes 7,076 - x bytes (44 bytes for identification)
Note
•
Make sure during programming that the total size of all the remanent data does not exceed the
maximum available range of 7,120 bytes.
This will avoid errors when transferring an application to the CECC.
