Table 6- 3
Conversion instructions

SCL
Description
out := <data type in>_TO_<data type
out>(in);
Converts a data element from one data type to
another data type.
1
For LAD and FBD: Click below the box name and select the data types from the drop-down menu. After you select the
(convert from) data type, a list of possible conversions is shown in the (convert to) dropdown list.

For SCL: Construct the conversion instruction by identifying the data type for the input parameter (in) and output
parameter (out). For example, DWORD_TO_REAL converts a DWord value to a Real value.
