Hello Friends,
I´ve got the same problem. The u850 Seems to Communicate via Modbus TCP. But I can´t find the way , how to get and set internal variables inside PLC. I do not understand the variables of PLC properties, like , PLCAddressValue, Txt, Visible . Could you help me ? i´m new in AB PLC. the video in youtube seems tobe old.
Thanks a lot
