Possible causes:
1. One or more sections selected for a download changes exceeds the maximum data size.
2. The PLC memory is too fragmented due to too many download changes .
3. Too many variables exist or the size of the variables exceeds the maximum data size.
4. Too many initial values were recently introduced.
5.The project is too big.
Solution:
1. Try the memory prediction to identify a section which is recommended for optimization and choose Optimize Section available in the project browser. Sections optimized in this way can be transferred to the PLC via Download Changes .
2. Identify unused variables in the variable editor, delete them and choose Optimize Project . This requires a complete Download .
3. Reduce the number of initial values.
4. Adjust (increase/decrease dependent on the circumstances) the amount of available memory for Global Data (Variables) in the PLC Selection dialog.
5. If the project is too big or the PLC memory seems to be fragmented try a complete Download .
6. Try an export/import via ASCII-file using the Concept Converter following with a complete Download . ASCII conversion leaves a memory-optimized project.
7. Identify memory-consuming DFB inputs/outputs and consider to use in outs.
8. If nothing works try using a bigger PLC.
