ABSTRACT:
A low cost, multipurpose digital IC is used as the basic building block in establishing a network communication system over a desired communication link. The digital IC can function as an addressable microcomputer interface between the network line and a remotely located microcomputer which may, for example, comprise any microprocessor based controlled product. In such mode, the digital IC's function is to take data from the network and pass it on to the remotely located microcomputer upon command from the central controller and to transmit data from the microcomputer to the central controller. The digital IC may also function as a nonaddressable microcomputer interface between the central or master controller and the network line. In such case the digital IC's function is to continuously take data from the central controller and place it on the network and take data from the network and pass it back to the central controller. The digital IC may also function as an addressable load controller associated with an individual remote controlled device and responding to shed or restore load commands from the central controller over the network line. When so used the digital IC may also be commanded to transmit a reply message back to the central controller giving information as to the status of the controlled device, thus enabling the central controller to monitor a large number of remotely located controllable devices.
