Function
The NumToEnum instruction converts the value of data to convert In, which is DINT data, to an enumer-
ation value and outputs that value to conversion result InOut.
Use this instruction, for example, to change the value of an enumerated variable from an HMI or other
display device that does not handle enumerated variables.
The following example shows how to convert the value of DINT variable In1 and output the results to
variable ColorA, which has an enumerated data type of Color. If green is the enumerator that corre-
sponds to an enumeration value of 1 for Color and the value of In1 is 1, the value of ColorA will be
green.
