Abstract: Abstract A  process  control  system  includes  redundant  digital controllers  and  a  plurality  of  input/output  (I/O) modules for interfacing with remote field sensors and actuators.   Bi-directional  communication  between  con-trollers  and  I/O  modules  is achieved by  a  parallel-wired,  process  I/O bus.   Failures  within the system, including the  bus  structure  itself,  that  continually keep the bus active (i.e., in a low state) are isolated by a  combination of software  diagnostic  routines for performing bus checkout and a unique quick disconnect feature that readily isolates the fault condition first between the I/O module nest area and the controllers, then, if necessary, to individual I/O modules.  During fault isolation procedures, individual I/O modules may be disconnected from the bus while the values of field signals are simultaneously maintained to provide mini-mum process upset.

Abstract: DEMULTIPLEXER CIRCUIT          Abstract A demultiplexer circuit which extracts from an incoming time division multiplexed digital bit stream any combination of PCM encoded words or data bits, irrespective of the rate of latter or the position of the data bits in a given channel or channels.  The demultiplexer circuit includes a random access memory for storing information as to the bit(s) to be demultiplexed out of the incoming digital bit stream.  A counter operates in synchronism with the received bit stream and the output thereof serves to access the random access memory to provide output signals indicative of the bit(s) carrying information for the subscriber station.  These output signals are utilized to read the digital signals intended for said station into other random access memory.  A summing circuit is coupled to the input of said other memory so that conference calls are summed in real time.  The digital signals are then read out of the other memory at a steady rate, with a stored data signal being similarly outputted irrespective of the rate of the signal or its position in a given channel or channels.
