LAD / FBD SCL
out := <data type in>_TO_<data type
out>(in);
For LAD and FBD: Click below the box name and select the data types from the drop-down menu. After you select the
1
(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
2
parameter (out). For example, DWORD_TO_REAL converts a DWord value to an Real value.
