Скачать или смотреть Python and Mitsubishi PLC communication

Demonstrate the use of Py MC Protocol package in Python for communication with Mitsubishi PLC (CPU built-in Ethernet Port).

pymcprotocol 0.3.0
https://pypi.org/project/pymcprotocol/

1)pip install pymcprotocol
(remark: required to know and have installed PIP in Python first. PIP is typically included by default with Python installations from version 3.4 onwards.)

2)PLC parameter
-Built-in Ethernet Port Setting
-Built-in Ethernet Port Open Setting
(remark: required to write PLC parameter to PLC & perform reset PLC)

3)Python example program run test
-Import the pymcprotocol PIP package
-Setup PLC connection(setting for PLC IP address, Port No, Communication Data Code)
-Connect to PLC
-Write integer value 10, 20, 30 to D100, D101, D102.
-Read integer value from D100 to D105
