Hi All,
Happy new year. I'm currently working on a project to communicate to a 5-axis machine which uses 840D controller. I need to develop a monitoring software (GUI based) which would read out the machine variables and also NC program from a HOST PC in realtime. I may/may not need to write to the R-variables on the controller. Can anyone let me know the optimal way to access the realtime data from machine? I see a few ways such as Access My Machine / OPC UA and Step 7 C-programming manuals but I'm not sure of the right way to start with. So I need to understand about which software and license is needed to access the machine remotely. And also whom to contact in this regards. Looking forward for these details. Thanks in advance.

Regards,
Raghav
