To integrate a hardware and software (functional) module into IntellectAxxon PSIM, perform the following steps:

1. Edit the DBI file.
2. Edit the DDI file.
3. Prepare a module.mdl file, where “module” is the name of the module to be integrated (this file is a transformed DLL file).
4. Prepare an executable file, module.run, where “module” is the name of the module to be integrated (this file is a transformed EXE file).
5. Copy module.mdl and module.run to the IntellectAxxon PSIM\Modules folder. 

Figure below shows a diagram of interaction between a functional module and the system core.

The DBI and DDI files contain information on the integrated functional modules (objects); this information is needed for the operation of the system core. The DBI file describes the structure of IntellectAxxon PSIM's configuration database. The DDI file describes the objects and their parameters. When an object is integrated, the name of the object, its parameters, and the related system events and reactions are added to these files.

In this document, we describe the steps for module integration by using the DEMO Axxon One Demo module, which emulates working with virtual hardware.  This module includes devices with unique addresses for accessing and polling these devices.  Thus the system includes a configuration consisting of 2 main objects: a parent object, DEMOAxxon One Demo, with the COM port parameter, and a child object, DEMO_DEVICE, with the Address parameter. The system allows you to perform a number of actions with devices and to pass all their events to the system core.
