The control library IToolS® (Industrial Component Tool Suite) is the answer to the interaction difficulties experienced by devices wishing to communicate via a common protocol. IToolS® is a software library containing its own communication drivers for the most popular devices used in the field of industrial automation. In addition to offering a number of controls for client/server communication management, it also contains several controls to use for one's communication client interface customisation. The framework IToolS®, has been entirely developed with the Microsoft .NET Framework technology; it is based on object-oriented programming characteristics and uses the powerful constructions made available by Microsoft .NET, while assuring compatibility with Windows CE. All IToolS® components rely on COM technology support: it is therefore possible to use IToolS® components in a variety of programming languages, from top level languages (.NET, C++, VB6, etc.) to scripting ones (JavaScript, VBScript, etc.)
