In a cluster i have 720 different data types elements how to convert it into array.

[JB]

All elements of an array must be of the same type. Therefore, it will not be possible to convert the cluster to an array if the 720 elements of the cluster are of different types. If they are all of the same and unique type, then you can use the Cluster to Array function.

All you have to do is convert each item into a common datatype - like a variant. Then you can put them all into an array together. All you have to do on the other end of the wire where the array is being used, is convert them back into their native datatypes before use.

What exactly are you trying to accomplish?
