New code works.   It reconnected on its own after the PLC had been off for 3 days.  Before I could not leave the PLC off over a 2 day normal weekend without having to restart the HMI software.

Thank you for hanging in there with this.  I will switch to the new code today.

What was the outcome of your extended testing?

Wireshark shows no traffic from AdvancedHMI.   Using version 399r.

We turn off power to our PLC's every night then back on again the next morning.   I've noticed that most days my Advanced HMI app reconnects fine on its own with no extra code by me but some days, especially after two day weekends,   the PC quits sending packets to the PLC and HMI gives "No Response" when reading. 
How does the retry mechanism work in HMI and when it quits sending packets, is that the Windows network stack or the HMI code?
