Is it possible to save variable data from an eCo PLC to a PC? The PLC and the PC are conected via serial RS485
I have a PC with a codesys visualisation connected to an eCo PLC PM554 through serial cable (RS485)
I want to save every few minutes the changing values of two variables (pressure and flow) from the PLC to the PC in a file (txt, excel, etc) for further study
My PLC only has one port (COM 1)
Is that possible?
Thank you in Advance
