Additional Information
For a function or function block for which the parameter specifies an enumerator, you can also
use the Enumeration#Enumerator notation. Therefore, for the above BinToBCDs_WORD instruc-
tion, the following notation can be used to pass the parameter to Format: _eBCD_FORMAT#
_BCD1.
 Value Checks
When a value is written to an enumerated variable through execution of an instruction, an error will
not occur even if that value is not defined as one of the enumerators of that variable. Therefore, if it
is necessary to confirm that a value is defined as an enumerator of an enumeration, write the user
program to check the value.
