Python sample for communication with Mitsubishi Electric CNC M700 series using EZSocket.
It works by using COM object in Windows environment.
Please use as a hint when implementing in your own environment.
-Reading and writing values to D and M devices -Acquisition of information such as NC status, tool number and rotation speed -Directory search and file operations in NC (read / write / delete)
The following Mitsubishi CNC communication software development kit is required in a Windows environment.
