Yes, I have a C:\Program Files\openHistorian\NModbus4.dll that is 74KB.
If it matters, I am online with the RTAC watching the ‘Offline’ and ‘Message_Sent_Count’ indicators to determine when OH is connected. It is as soon as I navigate off the page it drops the connection. By that I mean, if I click any other web button like ‘Home’ or ‘Devices’ the connection will drop.
I can however switch tabs and the connection is unaffected.
