  • the hardwired implementation is often undesirable. For instance, in cases where the control logic needs to be updated or modified slightly, the hardware in these control devices needs to be substantially reprogrammed or replaced. In particular, these control devices cannot adapt to slight modifications in the environment. Further, these devices are often sourced from a plurality of manufacturers. Each of these control devices may be based on a different communication protocol. A control device that supports only one kind of protocol will thus not be able to network with other devices. Thus, there is a need for a control device that is readily adaptable for a variety of control applications and, at the same time, is able to interact with other devices, with each device possibly implementing a different kind of protocol.
