Central processor supervised controller system having a simulation of

Abstract

In a system for controlling a machine tool by a tool controller under the supervision of a central data processor, in which the controller transforms the data provided by the central processor into a format compatible with the machine tool, e.g., clock pulse encoded data format suitable for writing into and reading out of a serial storage magnetic memory device, a test system is provided wherein the central processor includes a simulation of the controller. This simulated controller gives the processor the capability of simulating and applying to the tool controller data in a format equivalent to that normally applied to the tool controller from the tool itself, e.g., a clock encoded data read output. The simulated controller also provides the central processor with the capability of receiving from the tool controller a tool control output in the format compatible with the control tool, e.g., clock encoded data and changing said data into an original format usable in the central processor.
