Control collection

The Industrial Automation Group of Advantech has introduced ActiveDAQ Pro, a collection of ActiveX controls performing I/O operations.

The package contains device, AI, AO, DI/O, thermo, counter and pulse control and can be used with any ActiveX controls with any development tool that supports them, including Visual C++, Visual Basic, Borland C++ Builder, Borland Delphi and Visual Studio.NET.

The collection consists of components that enable users to build graph display modules for data acquisition and develop prototype vision applications in an interactive environment without programming.

The various controls are explained as follows: button control for various display styles (2D and 3D) and is a Boolean control that displays an on or off state; graph control provides abundant graph display function, which enables the user to display data of various sources simultaneously; intensity control offers two-dimensional display and simple interpolation for scattered 2D data points; knob control is circular data control that provides various graph styles; LED control provides data display and editing functions with the seven-segment nixie tube mode; NumEditor control provides functions of numerical displaying and editing; slide control is linear data control that provides various graph styles.

Other features include: support for Advantech DAQ cards and functions with complete high-speed data acquisition; easy-to-use property sheets offering selections that will provide an access to all settings, eliminating unnecessary programming; independent control operation, needing no support from other existing ActiveX controls; physical properties like voltage, current and frequency, which can now be directly applied by the user and will automatically be reassigned to the data with proper input range and sample rate; straightforward user interface — less hardware dependent; optional lists vs direct input which eliminates a large portion of the direct data input; default settings for quicker execution; properties and parameters which can automatically determine an appropriate data interfering method to perform the data acquisition; parameter check-up and correction, which is automatically corrected.
