Communication with CNC machine through DNC interface

This paper presents usage of modern CNC machine's DNC interface for communication with the machine and emulation of its work. The analysis shows the solution is achieved by embedding elements of PC-Windows platform and Ethernet technology into the machine controller, enabling that way interoperability with all hardware and software components connected to Ethernet network. The paper demonstrates the usage of standard Ethernet TCP/IP network as well as legacy RS-232 connections for remote control and machine tool state data acquisition. This is the functionality that further enables interoperability of the machine with distributed software components such as DCOM, CORBA and RTC. These may be used to empower machine tool with new function modules. Detailed description given here aims to contribute to deeper understanding of communication interfaces necessary for application of the technology for whatever purpose it may be intended: virtual production, smart manufacturing, distributed manufacturing or IIoT.
