{{anchor:tia_types}}
List of data types used by Simatic S7. The page contains the more modern TIA variable types as well as the earlier S7-classic types.\\
\\
There are four data types in: Boolean, Text, Numeric, and Date/Time. Each data type defines the format of information that can be entered into a data field and stored in your database. \\
