Constant: Typed Literal

With the ecxeption of REAL or LREAL-Constants (in this case, always LREAL is used) the smallest possible data type is used when calculating with IEC constants. If you want to use a different data type, you can use typed literals to do this without having to declare the constant explicitly. Provide the constant with a prefix that defines the type.

Syntax

<type> # <literal>

<type> specifies the desired data type. Possible inputs are BOOL, SINT, USINT, BYTE, INT, UINT, WORD, DINT, UDINT, DWORD, REAL and LREAL. You must capitalize the type.

<literal> specifies the constant. The input must go to the below <type> specified data types match.

If CODESYS cannot convert the constant into the target type without data loss, then an error message is issued.

You can use typed constants wherever you can use normal constants.
