How to handle when receiving Undefined Structure

Undefined Structure The message does not specify a message format, so it is unknown how the message will be received.
So you cant read Item with methods such as GetU1Item () and GetAsciiItem () right away.

[Use Return Value]
Retrurn value of GetSecsMsg () function and GetxxxItem It uses return value of (), but if error occurs, it returns the value less than 0. If not error, it returns Format value of next item.
Returns No item (63) if there is no next Item.
