Abstract

A remote station controller is described together with its software support, consisting of a programmable modern multiplexer and multiple remote receiver/transmitter units capable of time sharing a wide variety of remote digital devices. By this method, a cluster or group of devices are controlled by a small digital computing system and form a network to be used in the automation of laboratory and/or industrial instruments, sensors and terminal clusters. A network of small computing systems is supported by a central computing system forming a hierarchy of distributed control and data processing functions, as shown in Fig. 1.

Remote Station Controller

A remote station controller is described together with its software support, consisting of a programmable modern multiplexer and multiple remote receiver/transmitter units capable of time sharing a wide variety of remote digital devices. By this method, a cluster or group of devices are controlled by a small digital computing system and form a network to be used in the automation of laboratory and/or industrial instruments, sensors and terminal clusters. A network of small computing systems is supported by a central computing system forming a hierarchy of distributed control and data processing functions, as shown in Fig. 1.

Fig. 2 shows a block diagram of the remote station controller and is independent of the implementation media or computer system employed. The following features are descriptive of the apparatus: 1) A means of combining data, control interrupt and status transmission via a single common line pair and via purely digital techniques. 2) A means of providing functionally asynchronous communication between synchronous or asynchronous systems, having a wide variety of operating rates. 3) A means of providing common high-speed communication between systems having bit, character, and/or word stream manipulation requirements. 4) A means of providing an interrupt driven operating environment, in which the functions to be performed are physically independent of the interrupt source. 5) A means of providing complete autonomy to t...
