4.4.4 STEP7 Data Types<br />
4.4.4.1 Support of the Process Data Editor<br />
In the process data-editor (Symbol Configuration dialog) data can be read<br />
from or written to the data blocks DB and from/to the symbol area of the<br />
PLC. The symbol area includes the areas:<br />
• Merker (M, MB, MW, MD)<br />
• Counter (C)<br />
• Timer (T)<br />
• Input Area (I)<br />
• Output Area (O)<br />
