Hello,
I'm trying to create a HMI, connecting to RSLogix 500 Emulator. I created a virtual serial port pair, COM1<-->COM2. And when I'm trying to run this program, its throwing the following unhandled exception.
A first chance exception of type 'MfgControl.AdvancedHMI.Drivers.Common.PLCDriverException' occurred in AdvancedHMIDrivers.dll

Can anyone please help me with this??
