Abstract:
A control system having a man-machine interface controller and a numerical controller, and interactively performing data input/output operations therebetween, the control system comprising:an interactive data processing unit comprising a remote access control unit, disposed within the man-machine interface controller, transmitting an access request to a serial transmission line and receiving data coming via the serial transmission line; anda control unit, disposed within the numerical controller and connected to said interactive data processing unit via the serial transmission line, said control unit comprising a memory, a numerical controller processor, and an internal data input/output unit directly accessing the memory in response to the access request input via the serial transmission line, writing write-data for controlling servo amplifiers of a machine tool into the memory, and transmitting read-data read from the memory to the serial transmission line in response to the access request, said access request accessing an arbitrary address of the memory in said control unit without intervention by the numerical controller processor.
