Hi autocar,
LabVIEW help for ArrayToCluster tells about this limitation…
Solution: create typedefine a cluster with a reasonable number of elements (atleast less than 257)…
Why do you need a cluster with more than 256 elements?
(And why did you need to hijack on old and unrelated thread?)
Best regards,
GerdW
