Everything I posted came straight out of TIA Portal's F1-Help system, with a little "extra" wrapped around the details.  What I am saying is that I posted "Siemens's solution".

Thank you very much for the support.

I will try your solution 

 

HI 0_Einstein expert sir,

wincc advanced modbus rtu connection not resuming AFTER DISCONNECT AND RECONNECT.

I have successfully communicated with delta plc on wincc advance v16 with Modicon modbus rtu protocol, everything is working fine.

but there is big problem wincc does not resume communication after cable disconnection and on connection again. Whereas i have tested keeping same PLC and communication setting with other HMI devices and it works flawlessly (Auto resume communication).

can anyone have idea how to make auto resume connection using Modicon modbus rtu protocol in wincc runtime advance v16.

thank you,
