Title: Data transmission system
Inventor: KIM BYUNG-KI
IPC: G05B19/18
Filed: 1989-04-13
Granted: 1991-07-31
Abstract: The system performs the unified control  of  function  blocks separately designed and carries out transmission of  data  quickly and correctly. The controller comprises: CPU (1)  for  controlling sections via system bus (9); memory  section  (2)  for  memorizing data; servo controller (10) for adjusting shaft position via shaft controller (3);  data  communication  section  (4)  for  operating tape-reader/puncher;  PLC  (5)  for  controllign  relay;   graphic controller (6) for controlling keyboard (7), CRT display (8).  The data transmission system comprises the master function board  (41) for  transmitting  data  to  system  bus  (33)  via  buffer  (14), shaft-control function board (42) for exchanging data with the bus (33) via buffer (15), graphic function board (43) for  controlling the graphic display and exchanging data, PLC function  board  (44) for controlling relay via controllers (28),(29).
