Compiler Error C0078

Message: Unsupported type: '<data type>'

Possible error cause: The used type is not supported by the current device and therefore cannot be used.

Error correction: If possible, use a different type. For example, ‎REAL‎ instead of ‎LREAL‎.

Example of the error:

PROGRAM PLC_PRG
VAR
    value : LREAL;
END_VAR


--> C0078: Unsupported type: 'LREAL‘

Error correction:

Example:
PROGRAM PLC_PRG
VAR
    value : REAL;
END_VAR
