Safe data types

The following data types are used in the safe blocks.Each of the following safe data types is a directly →derived data type. Its base type is an elementary data type according to "Supported data types (in ST)".

Name	Base type
`SAFEBOOL`	`BOOL`
`SAFEBYTE`	`BYTE`
`SAFEDATE`	`DATE`
`SAFEDINT`	`DINT`
`SAFEDT`	`DATE_AND_TIME`
`SAFEDWORD`	`DWORD`
`SAFEINT`	`INT`
`SAFELINT`	`LINT`
`SAFELREAL`	`LREAL`
`SAFELWORD`	`LWORD`
`SAFEREAL`	`REAL`
`SAFESINT`	`SINT`
`SAFETIME`	`TIME`
`SAFETOD`	`TIME_OF_DAY`
`SAFEUDINT`	`UDINT`
`SAFEUINT`	`UINT`
`SAFEULINT`	`ULINT`
`SAFEUSINT`	`USINT`
`SAFEWORD`	`WORD`

Observe:

If you connect the input/output of a block for safe logic to one of these safe data types, the background color of this block might be changed to a shade of yellow. Details: See "Highlighting safe logic in the FBD-editor".

Due to the implicit conversion of Neuron Power Engineer you do not have to enter additional code in your application, if you want to convert a safe data type to its base type. Example: The safe data type SAFEINT can be converted implicitly to its base type INT.
If you want to convert a base type to the corresponding safe data type, you must call the respective safe convert function in the application. Example: Call the TO_SAFEINT block for a conversion from INT to SAFEINT.
