Enterprises are adopting the Internet of Things paradigm as a
strategy to improve competitiveness. But enterprises also need to rely on their
legacy systems, which are of vital importance to them and normally difficult to
reconfigure or modify, their mere replacement being usually not affordable.
These systems constitute, therefore, barriers to agility and competitiveness, raising
the need to develop cost-effective ways for IoT adaptation. An approach for
adapting legacy manufacturing systems into the IoT realm is proposed in this
research. The methodology is twofold: an adaptation board is firstly designed to
provide IoT connectivity, allowing to remotely invoke the “legacy” functionality
as services. Then, the board itself can leverage the legacy system by developing
additional functionalities inside it, as the update process is usually triggered
by the need of new functionality from these systems. An experiment, which
consists of adapting to IoT a small distribution line that is controlled by an aged
Programmable Logic Controller, is developed to illustrate how straightforward,
affordable and cost effective the adaptation approach is, allowing to holistically
achieve a new system with more sophisticated functionality.
