ABSTRACT:
A numerical controller which allows easy and inexpensive construction or expansion of a control system and flexible construction of a sequential control section for a variety of system structures. The numerical controller has a numerical control section having multiple control systems. Between the numerical control section and a sequential control section, interfaces are provided for the individual control systems of the numerical control section. The control systems are assigned to the interfaces so that the control systems will be each controlled by an intended one of sequence programs (ladders1through3) installed in the sequential control section, under which signals are sent and received independently. The numerical control section and the sequential control section send and receive signals through the interfaces to which the control systems are assigned. By changing the assignment, the control system can be reconstructed freely, without adding a new programmable controller.
