Using AdvancedHMI Libraries

In a recent project I used the www.advancedhmi.com which required ModbusRTU communications. The package though fairly open source has some closed source elements. The closed source is predominantly in the driver PDU request handling + optimization and also in the custom controls.  I did like the custom controls and purchased the extended custom control libraries which are great for adding a professional look and feel to mimic a control cabinets dials, lights, pushbuttons  and digital and analogue readouts. The support response from Archie was great.
