Hello Archie ,
With earlier versions before 399 , we could change station address property and communicate with multiple ModbusRTU stations .
Here if any station does not respond , Read write to other stations was not affected , screen continues to show other station registers.
But With version 399 onwards , if any station does not respond within timeout period , communication to alll nodes (stations ) stops .
Trying to find out reason , still no joy .
Nodes 1 ,2,3 ,4 ,5 ,6 ,7 all working ok ...
Now if node 4 stops responding (In real field situation it can happen, that machine may be down), initially 4 ,5 , 6, 7 stop responding , and then 1,2,3 also stop resp,onding .
I tried to debug with Mod R Sim found that AdvancedHMI stops polling if any one device is unresponsive . Earlier it wasnt this way .

I'll see if I can round up 2 ModbusRTU devices to test this out and see if I can figure out the issue.
