Simulating-modeling
To construct the simulator of the technological process, basing on the available devices models, the original principal diagram and the block calculator (BlockCalc) of OpenSCADA were directly used. The devices models of the technological scheme were appended to the block scheme in accordance with the principal one. Part of the blocks were been added for the auxiliary equipment, as well as for the flow nodes. Numbers of the node blocks on the principal diagram are indicated by numbers near the flow nodes.
