Software Toolbox: Custom OPC Client Toolkit

Version 5.20 offers new "codeless" development functionality, support for logical data objects and enhanced browser form control objects. Codeless functionality introduces both BindingExtender and DABinder components that extend the properties of controls and enables the user to easily bind OPC tag data directly to the control without writing code. This feature supports all basic OPC functionality including reads, writes and subscriptions, eliminating the need to know the intricacies of OPC. The user can extend this functionality to common Windows form controls, such as textboxes and labels, or visual objects, such as the company's Symbol Factory or Industrial Gadgets libraries. Also new is OPC live mapping, which allows the development of objects that correspond logically to the functionality provided by equipment or processes that are providing the OPC data. The release also includes several new Windows Forms browser controls and provides functional and visual updates to existing browser controls. One of the most useful new objects is the Generic OPC Browsing Dialog. This object will allow the user to use one object to browse items in OPC DA, A&E or UA servers, rather than a separate object for each specification type, for increased efficiency. A trial version is available for free download at http://opcdataclient.com/html/free_trial.asp.
