mitsubishi-cnc-m700

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.

Implementation function

-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)

How to use

from m700 import M700

# Open connection
m700 = M700.get_connection ('192.168.1.10:683') #683 is the default port for Mitsubishi M70 CNC controllers

# Get information in NC
m700.get_drive_infomation ()
m700.get_run_status ()
m700.get_alarm ()

# Operation on D device
m700.write_dev ('M900', 1)
m700.read_dev ('M900') #-> 1

# Operations on M device
m700.write_dev ('D200', 10)
m700.read_dev ('D200') #-> 10

# Manipulate machining program files (read / write / delete)
drivenm = m700.get_drive_infomation ()
m700.write_file (drivenm + '\ PRG \ USER \ __ TEST __. txt', b'TEST_WRITE ')
m700.read_file (drivenm + '\ PRG \ USER \ __ TEST __. txt')
m700.delete_file (drivenm + '\ PRG \ USER \ __ TEST __. txt')

# Close connection
m700.close ()
