A Machine Tool Interface Unit Using MODBUS Protocol

The present invention relates to a machining tool interface unit using Modbus standard protocol, and more particularly, to a machining tool interface unit using Modbus standard protocol, in which a communication scheme of a machining tool is improved, thus a user communicates using a standardized Modbus protocol through a newly generated Modbus map. Data in a machining tool controller is connected to addresses of the Modbus map, so that the user obtains a type and a location of the data through the Modbus map of the machining tool controller. By communicating using the Modbus protocol through the Modbus map, a maker communicates with the machining tool without another machining tool or a program made by the maker for her/himself, so that various operations such as spindle speed, spindle stopping and moving, load, control of moving speed etc., and sequence of an NC program are monitored and controlled. In addition, a delay time is prevented between an operation and removal of the machining tool, thus the operation is performed in real time.
