Compiler Error C0197

Message: Implicit conversion from '<data type 1>' to '<data type 2>': possible loss of information

Possible error cause: An attempt is made to convert a variable from data type DINT or LINT to data type REAL.

Error correction: For DINT, use the data type LREAL, and when converting from LINT to LREAL make sure that the value of LINT does not exceed the capacity of LREAL.

PROGRAM PLC_PRG
VAR
    i : DINT;
    b : REAL;
END_VAR
b := i;
