Cann't connect to the Haidenhain system (version TNC640)

Hi drunsinn

  I think there maybe something wrong in the program, or something configuration in the machine had been modified.

 One controller infomation of grob machine can be read from the program:
 Controller Information:
 TNC-Type:  TNC640
 NC-Version:    340590 10 SP2
 PLC-Version:   TNC640_V14.06.05

But the other controller infomation of HERMLE machine(C42U) can not be read suddenly。

This is an earlier result：
E:\pyLSV2-master\venv\Scripts\python.exe E:/pyLSV2-master/JCTest.py
Connecting to 192.168.1.37
{'Control': 'TNC640', 'NC_Version': '340590 10 SP3', 'PLC_Version': 'C42.33.04SP2HF1/S/'}

Did you manage to fix it yourself? Looks to me like the control didn't respond. Let me guess, you had to enable the connection on the control? Been there myself ;-)

Hi drunsinn

     You are right.

     I had downloaded a program from the other website. It is the same result. 

     I found some information on that website, so I go to the machine to check the configuration.

     The ip in our customer factory had been changed. So the py program has no authorization to access the controller.

      Thank you all the same.
