/*! /brief generic class for QW function blocks providing access to one word physical output
 *
 * In order that this FB can be used implementations need to provide a class CProcessInterface
 * this class needs to inherit from CCProcessInterfaceBase and provide the following functions
 *
 *   - bool initialise(bool paInput)
 *     Initialize the physical output identified with the value of the PARAMS FB input
 *       - @param paInput: if true it should be an input, if false it should be an output
 *       - @return true on success, false on error
 *
 *   - bool deinitialise()
 *     Deinitalize the physical port
 *       - @return true on success, false on error
 *
 *   - bool writeDWord()
 *     Write the value of function block's IN() data input to the physical input
 *       - @return true on success, false on error
 *
 * TODO a higher flexibility and easier use could be achieve if the base class would be a template parameter. However
 *   currently it is very hard to templatize a function block class.
