The characteristics of DCS level two are complex function and large amounts of data.They seriously affect system's performance.Using a fully open configuration software to simulate the ADACS system configuration is a challenge.How to design and choose the configuration scheme to meet the requirements is the key to complete the DCS level two simulation configuration.Simulation configuration on DCS level two can be divided into three parts, data structure, logic computation, and graphic configuration.Two kinds of data structure designs are compared according to the function requirement.The database is not divided depend on object types but according to the function of the data.Define the equipment code name as the unique key and define generic data structure according to the function.The equipments belong to same POT, their will have similar data composition.Establish a table which shows the symbol of equipment and its related POT types.Logic computation and graphic configuration can be designed flexibly to match various template functions.The optimization design schemes improve the development situation of the project.Through the actual project verification, the simulation designs discussed in this paper, can meet the schedule and technology requirements for production project and scientific research.
