Q: In which way in OpenSCADA possible to realize inter-modular connections?
Re: Inter-modular connections can be of the following types:
- The standard interface of access — is made by means of the virtual interface of the modular subsystems.
- The expanded interface of access — provides export of functions of the external interface by means of the exporter module, and the subsequent connection of the importer module to these functions by means of the functions "TModule::modFunc()".
- The user functions — any component of the program can register its own user functions ("TCntrNode::objFuncCall()"), which can be used further in an environment of the user programming of OpenSCADA.
