Abstract
PURPOSE: To establish the input and output control circuit providing the function to check the shift register to transmit the control information to the controlled unit in the sequencer.
CONSTITUTION: The parallel input data from the input circuits IN1WINn is stored in the memory section ME in the sequencer SQ serially via the transmission shift registers SR1WSRn. The control section CT transmits the data serially to SR1WSRn after processing it at operation section AL. This processed data controlls the controlled unit (not shown) via the output units OUT1WOUTn parallelly. After power supply is applied to the entire unit and clear signal s is made, ME delivers the check code to SR1WSRn. Further, the clock counter CN adds the check code to before and after the control data. When the code is circulated and returns to the shift register CR for check code, the comparison section CM checks whether the check code is correctly returned or not.
