Archie,
My testing was done using Modsim32 by Win-Tech Software on the same PC as the Advanced HMI.
The error has always been "Illegal Modbus Address" when using the DigitalPanelMeter.
For the BasicIndicator there mostly is no error, but the Bit values return incorrectly.
I am using Windows 7 in 64-bit mode.
Thanks very much.
