| | What is not included in the table: \\ |
| | **BCD numbers**, BCD16 and BCD32. BCD numbers do not have their own data type. For a BCD number, use the data type WORD or DWORD and enter only the digits 0 to 9 and 0 or F for the sign in the format in hex W#16#xxxx or W#16#xxxx_xxxx. You can also use the notation c#0 through C#999 for a positive three-decade decimal number. |
| | |
| | PLC data type (**UDT**), Anonymous structures (**STRUCT**), **ARRAY**, Parameter types (**TIMER**, **COUNTER**,..), System data types (**IEC_TIMER**, **IEC_SCOUNTER**,..) |

| | ===== "Base" conversions ===== |
| | The TIA Portal offers many conversions (and doesn't offer many more). These are summarized in the following table: |
| | ^type^solution^conversions| |
| | |Int|"CONV"|DInt, Real, Bcd16, USint, UInt, UDint, SInt, LReal und Char| |
| | |DInt|"CONV"|Int,Real, Bcd32, USint, UInt, UDint, SInt, LReal und Char| |
| | |Real|"CONV"|Int, DInt, USint, UInt, UDint, SInt und LReal| |
| | |USint|"CONV"|Int, DInt, Real, UInt, UDint, SInt, LReal und Char| |
| | |UInt|"CONV"|Int, DInt, Real, USint, UDint, SInt, LReal und Char| |
| | |UDint|"CONV"|Int, DInt, Real, USint, UInt, SInt, LReal und Char| |
| | |SInt|"CONV"|Int, DInt, Real, USint, UInt, UDint, LReal und Char| |
| | |LReal|"CONV"|Int, DInt, Real, USint, UInt, UDint, SInt| |
| | |Char|"CONV"|Int, DInt, USint, UInt, UDint, SInt und Char| |
| | |Bcd16|"CONV"|Int| |
| | |Bcd32|"CONV"|DInt| |
| | |
| | === "CONV" utility === |
| | - In the "Instructions" palette of the block editor, open the "Simple Instructions > Converter" folder and insert the "CONVERT" instruction into your network using drag & drop. |
| | - After inserting the instruction box, the data types of the instruction are not yet defined and therefore the placeholders "??? to ???" are still below the "CONV" designation. When you move the cursor over the left triangle of the first three question marks, an arrow button appears. |
| | - Click on the left arrow button and select the desired data type for the input parameter "IN" (e.g. Int) from the drop-down box that opens. |
| | - Repeat the process for the "OUT" output parameter and select the data type into which you want to convert the numerical value (e.g. Real) from the drop-down box on the right. In this example, a numerical value from the Int data type can now be converted to the Real data type ("Int to Real"). |

| | |
| | **Install converters in TIA Portal:** |
| | - ZIP File: Extract the downloaded zip file to a directory |
| | - TIA Portal -> Devices window -> External source files -> Add new external file -> Select file |
| | - Switch online to offline |
| | - Right click on the inserted file in the list -> Generate blocks from source |
| | - "Block can be overwritten" warning -> click OK |
| | - Enjoy the time we gained with this copy (maybe write thanks to the author) |
