<p>The method involves detecting product states (alpha A, beta A) by an information detector (2'), and transmitting the states to information receivers (1', 1'') by an information provider (3) i.e. computer screen input mask. The states are periodically requested by the provider at time intervals, and are automatically transmitted to the receivers during change of the states to a changed product state. Requests (a', a'') of the receivers with the provider is stored on an electronic data carrier, and/or the product states with the detector and/or the information provider is stored on the carrier.</p> |
