New Structural Model of Intelligent Plant

In the model of ISA95, the structure of intelligent plant has been elaborated. The picture below shows extensional ISA95 IIoT model.

As the picture shows, the up-dated IIoT structure consist of two parts and is divided into 5 levels, namely site level, transmission level, control level, plant level and enterprise level. The blue part in the middle of plant level is what we know as automated plant solution. From the bottom up, respectively lie the sensor & actuator, IO module of control system, elementary control system, MES and ERP, which are the automation solutions for process plant solving problems of autonomous operation of plant. With the help of automation solution, process plant can operate continuously.

The deep blue part on the left is optimized control solution based on traditional automation solution. From bottom to top, there are newly added sensor, IO expansion, flattening system and optimizing of production and alarm, which are indispensable for the construction of automation plant.

The purple part on the right is intelligent plant solution based on IIoT. From the bottom up, respectively lie pervasive sensing, wireless network and analyzing and utility APPs. The solution for intelligent plant merges together with automated plant solution in level 4(MES & ERP), consisting a brand new overall structure of intelligent plant.
