The utility model relates to a control system network architecture, comprising at least one core switch configured with a virtual local area network access control list and a plurality of access switches connected with peripheral control system devices and configured with corresponding virtual local area network addresses according to the control system devices. Each of the access switches is connected with the core switch through at least one fiber. The control system network architecture is advantaged by applying the virtual local area network (VLAN) to replace a traditional control device subnet so that a control system network is simplified into a unitary flat structured network; the resource integration of an control system environment is further realized; the network hardware resource consumption and the electric power consumption are reduced; the types and the numbers of network equipment are reduced; the reliability and the network management capability of the overall control system network are greatl
