A3.2 Controller Internal Structure

The internal structure of Exasmoc controller is described in the following section.

 Controller Embedded with Application, Shell & Kernel

Above figure is a self-explanatory representation of Exasmoc functional blocks. To understand the Exasmoc controller’s execution it is important to understand Exasmoc controller who consists of three levels, Application, Shell and Kernel. These levels are described below along with various functions within every level.
The Application level retrieves the process measurements, the Operator/Engineer entries and the controller design data to be passed on to the Exasmoc shell. Shell level prepares this data for Kernel level where actually control algorithms executes.
Figure 3.2b provides a graphical representation of the three distinct levels, real time database, process I/O from DCS and operator entry and display parameters. The functional details of Exasmoc Controller an embedded system is given below.
