Structures

The structure definition is shared by standard programs and safety programs. However, it cannot be used in the following
cases.
• A member of the primitive data type which cannot be used in safety programs exists.
• An initial value is set in the structure definition.
34.5

Constants

The decimal constant (K) and hexadecimal constant (H) can be used in safety programs. The specification method is the
same as that for standard programs. (Example: K1234, H1FFF) ( Page 401 CONSTANTS)
