CompactRIO (CRIO) can be based to achieve time synchronization between multi systems on the based of IEEE 1588 synchronization protocol.This paper introduced the hardware composition, software design and synchronization test results of a remote distributed data acquisition system of CRIO.The test results show that the synchronization precision of the distributed system based on CRIO can reach sub millisecond level in short-term, and ms level in a long-term test.
