Abstract
Embodiments of a system, method and computer program product are described for instantiating additional programmable logic controller (PLC) functionality. In accordance with one embodiment, an extension for a PLC may be identified and loaded into a memory space of the PLC. The loaded extension has an initialization interface that may be exposed to the PLC. When the initialization interface is invoked, functionality of the PLC may be passed to the extension as at least one parameter of the invoked initialization interface. The extension can then be initialized utilizing the passed functionality.
