Communication method for DCS simulation software of full-range analog machine

The invention belongs to the technical field of computer application, and particularly relates to a communication method for DCS simulation software of a full-range simulator. Comprising the following steps: S1, initializing; s2, data transmission; and S3, the work station host stores communication point data, and data required by local functions are directly read from the local shared memory. The method has the beneficial effects that a plurality of shared memories are respectively arranged in the data server and the work station, and during working, the shared memories are taken as main bodies, and transmission and coverage are carried out at the data server and the operator work station; the data server and the operator work station are respectively provided with a special semaphore shared memory and an analog quantity shared memory, during data transmission, a shared memory block is taken as a main body, transmission and coverage are carried out at the data server and the operator work station, data point
