A processor facility includes a CPU and a PCMCIA card coupled with each other with a data or address or control bus. The hydraulic service module comprises an outer casing defining an enclosure therewithin including an air chamber in fluid communication with an ambient air. The software program generates information to provide visual cues representing a Jam Acceptability Region contour, a Jam Assessment Strobe and text for display on a number of flexibly configurable display formats posted on display units. The computing server establishes an exercise model according to the control signal and power signal and combines the exercise model with an information model stored in the storage server to generate a display signal. The data record is loaded into a buffer store, is checked by the buffer store and is interpolated by means of an interpolator, in order to move the industrial robot on the path element. Each of the pages contains illustrative material, such as text andor pictures, and at least one of the pages is partially transparent, so that illustrative material on subsequent pages is visible to the reader through the transparent portion of the page.
