The physical control cabinet and the virtual simulation model can be simultaneously connected with the process system simulation model to operate to carry out DCS software and hardware verification, and the physical control cabinet can also be cut off and independently connected with the process system simulation model to operate through the virtual simulation model to carry out DCS software verification. The method enables the verified virtual simulation model to be tested in an environment closer to reality, can realize cross verification and rapid verification of various large DCS system functions and configurations, and improves verification efficiency and verification reliability.
