Read online retain values from AC500
I would use a Red Lion HMI, you can access the varables using Modbus RTU.
The screen can then build a Data Logger of the varables with lables of each one.
The Logged varables can be exported to a CSV file using a Free untility called websync.exe
If you need more flexability on how it is formatted Red Lion can run "C" programs to format how you need your text.
