Abstract
PURPOSE: To make it possible to insert and extract process input-output units without exerting an influence upon each unit in operation, by transferring data via an input data register or output data register provided to each process input-output unit.
CONSTITUTION: When data are sent from central processor CPU to a process input- output unit, a set signal is sent to one of output registers OREG of output parts OAD1WOADN corresponding to output units OD1WODN assigned by an address signal, thereby setting output data. Process input unit ID1, on the other hand, sends data at every constant time and input control curcuit ICNT writes it in input data register IREG so that the contents of input data register IREG will show the state of process input unit ID1 all the time.
