Title:
AUTOMATIC TURN-ON/OFF DEVICE FOR INPUT/OUTPUT
Document Type and Number:
Japanese Patent JPS5798001
Kind Code:
A
Abstract:
PURPOSE:To reduce the time for a design, manufacturing and a test by automatically changing over plural input/output (I/O) point selecting the output point from the second hierarchy from the last, and the input point from the last one by an operating part of a hierarchy structure. CONSTITUTION:Output points A-C of an output part 1 and input points H-J of an input part 2 are selected by an operating part 3, and are changed over by a relay part 4. The operating part 3 consisting of a hierarchical structure of last- in-first-out operates switches S11- in the 2nd hierarchy from the last to apply an input to an OR gate in an output selecting part 6, and switches W11- in the last herarchy to apply an input to an OR gate in an input selecting part 7. The outputs from the selecting parts 6, 7 are inputted to an AND circuit 5, the relay part 4 is controlled by the command of a start sommand ST1, and automatic switching over of plural I/O points is carried out. Also, the I/O points selected by the selecting parts 6, 7 and the circuit 5 are displayed respectively in the output display part 8, the input point display part 9 and the I/O connection display part 10.
